Key Takeaways

• Humidity sensing is not the same as humidity control: A thermostat may display indoor humidity without controlling a humidifier or dehumidifier, so check the specific equipment support you need.
• Room sensors address a different problem than humidity sensors: Models such as the ecobee3 Lite bundle and Honeywell T9 can help account for rooms that run hot or cold, but that does not make their humidity features interchangeable.
• The ecobee Enhanced leads on feature balance: It pairs humidity monitoring with a broader smart-thermostat feature set, while the simpler Sensi and Nest options may suit buyers who want fewer system extras.
• Honeywell’s lineup calls for careful model matching: The T9, X2S, X7S, X7B, X8S, and ElitePRO S1200 differ in display, sensing, and smart-home details; similar names do not guarantee identical capabilities.
• Compatibility can outweigh the feature list: Wiring, HVAC type, and accessory needs may rule out a preferred model, making the product’s installation requirements a practical first filter rather than a final check.

More Details on Our Top Picks

1. Sensi Touch 2 Smart Wi-Fi Thermostat, Alexa Compatible, ENERGY STAR Certified (ST76)

   

   Best for Sensor Expansion

   View Latest Price

   The Sensi Touch 2 is a good fit for buyers who want to build a larger room-sensing setup over time. It supports up to 15 separate Sensi Room Sensors, giving it more expansion headroom than the ecobee Smart Thermostat Enhanced, though the sensors are an added purchase. Its touchscreen, scheduling, remote access, and usage reports make everyday adjustments and energy tracking straightforward. The listed product details do not specify a humidity-sensing feature, so I would not choose it for humidity readings or humidity-based control; its sensor support is for room comfort balancing. The main installation hurdle is the required C-wire, which rules it out for some existing setups. Pick it for multi-room temperature management, not for buyers whose main goal is monitoring indoor humidity.

   Pros:

   • Supports up to 15 separately sold Sensi Room Sensors
   • Touchscreen controls, app access, and flexible scheduling
   • Provides energy usage reports, equipment alerts, and maintenance reminders
   • Works with Alexa, Google Assistant, and SmartThings

   Cons:

   • A C-wire is required for installation
   • Room sensors are sold separately
   • The supplied product details do not identify humidity sensing

   Best for: Homeowners who want to add multiple compatible room sensors for temperature balancing and already have a C-wire.

   Not ideal for: Buyers specifically seeking a thermostat with a documented humidity sensor or homes without a C-wire.

   • Model:Sensi Touch 2 ST76
   • Connectivity:Wi-Fi, 2.4 GHz and 5.0 GHz
   • Display:LCD touchscreen
   • Power:C-wire required
   • Supported systems:Air conditioner, boiler, furnace, heat pump
   • Room sensor support:Up to 15 compatible Sensi Room Sensors, sold separately

   Our verdict

   “Choose the Sensi Touch 2 for an expandable room-temperature sensor setup, but skip it if humidity sensing is your deciding feature.”

   → See it on Amazon →

2. Sensi Smart Thermostat (ST55) – Wi‑Fi, DIY, Alexa, Energy Star Certified

   

   Best for DIY Installation

   View Latest Price

   The Sensi ST55 is the straightforward choice for buyers who value a guided installation and broad smart-home support more than a touchscreen. Its built-in level and app instructions can make replacing a standard thermostat less fiddly than setting up the Sensi Touch 2, while its compatibility includes Apple HomeKit as well as Alexa, Google Assistant, SmartThings, and Vera. It offers remote control, scheduling, and a filter indicator, but the supplied details do not list a humidity sensor. That makes it a weaker match for this roundup’s humidity focus than the ecobee Smart Thermostat Enhanced, which explicitly lists humidity control. The ST55 uses button controls and a small LED display, and wiring needs vary by system despite its battery backup. Choose it for a practical DIY upgrade, not for on-device humidity information.

   Pros:

   • Built-in level and app-based installation guidance
   • Supports Alexa, Apple HomeKit, Google Assistant, SmartThings, and Vera
   • Offers remote control, programmable schedules, and a filter indicator
   • Includes two AA batteries for backup

   Cons:

   • Product details do not specify a humidity sensor
   • Small LED display and button controls are less convenient than the Sensi Touch 2 touchscreen
   • Some HVAC systems may require a C-wire

   Best for: DIY-minded homeowners replacing a standard thermostat who want app-guided installation and Apple HomeKit compatibility.

   Not ideal for: Buyers who need documented humidity sensing, a large touchscreen, or guaranteed installation without checking their wiring.

   • Model:Sensi ST55
   • Connectivity:Wi-Fi
   • Display and controls:5-inch LED display with button controls
   • Power:24 V AC; two AA batteries included
   • Mounting:Wall mount
   • Supported uses:Air conditioner, boiler, furnace, heat pump temperature control
   • Compatible platforms:Alexa, Apple HomeKit, Google Assistant, SmartThings, Vera
   • Additional features:Programmable scheduling, filter indicator, data privacy features
   Our verdict

   “Pick the ST55 for guided DIY setup and wide assistant support, but choose a model with documented humidity sensing if humidity is central to your decision.”

   → See it on Amazon →

3. ecobee Smart Thermostat Enhanced

   

   Best Overall for Humidity Features

   View Latest Price

   The ecobee Smart Thermostat Enhanced earns the lead among these five because it is the only one whose supplied product details explicitly describe built-in humidity control. That makes it a more direct fit for a humidity-focused roundup than either Sensi model, whose listed features center on temperature scheduling and room sensors. Its occupancy sensing and schedule-based adjustments can also reduce heating or cooling when rooms are empty, while compatibility with Alexa, Google Assistant, Apple HomeKit, and SmartThings gives it broad smart-home reach. Homes without a C-wire can use the included Power Extender Kit, a useful advantage over the Sensi Touch 2’s stated C-wire requirement. Still, room-by-room sensing needs separately sold SmartSensors, and the supplied information describes humidity control without detailing specific humidity thresholds or dehumidification hardware.

   Pros:

   • Explicitly includes built-in humidity control
   • Occupancy sensing can adjust heating and cooling around room use
   • Power Extender Kit supports some installations without a C-wire
   • Works with Alexa, Google Assistant, Apple HomeKit, and SmartThings

   Cons:

   • SmartSensors for room-by-room comfort are sold separately
   • Some installations still require a C-wire or the included Power Extender Kit
   • Product details do not describe humidity thresholds or dedicated dehumidification equipment

   Best for: Households seeking documented humidity control, occupancy-based adjustments, and broad smart-home compatibility.

   Not ideal for: Buyers who want included room sensors or need detailed humidity-control specifications before choosing.

   • Connectivity:Wi-Fi
   • HVAC compatibility:Listed as compatible with 90% of HVAC systems
   • Display:4-inch LCD
   • Power:24 V corded electric; C-wire or Power Extender Kit may be needed
   • Humidity feature:Built-in humidity control
   • Occupancy feature:Built-in occupancy sensing
   • Smart-home compatibility:Amazon Alexa, Google Assistant, Apple HomeKit, SmartThings
   • Warranty:3 years
   Our verdict

   “For the clearest documented humidity feature in this group, choose the ecobee Enhanced, accepting that room sensors are an extra purchase.”

   → See it on Amazon →

4. ecobee3 Lite Smart Thermostat with Whole Home Sensors Bundle

   

   Best Included Sensor Bundle

   View Latest Price

   The ecobee3 Lite bundle stands out for what comes in the box: a SmartSensor for room occupancy and temperature plus a Door and Window Sensor. That gives it a more ready-made room-awareness setup than the ecobee Smart Thermostat Enhanced, whose SmartSensors are sold separately. The thermostat listing also identifies humidity detection, making it a better match for this roundup than either Sensi model. Buyers should separate that listed detection feature from claims of active humidity control: the supplied details do not explain specific humidity adjustments. The door-and-window sensor can support HVAC pausing when a window or door is open, but that feature requires a paid Smart Security subscription. It is a compelling bundle for buyers who want sensors included, though wiring conditions may still call for the supplied Power Extender Kit.

   Pros:

   • Humidity detection is listed among the thermostat features
   • Includes a SmartSensor for room occupancy detection
   • Includes a Door and Window Sensor
   • Power Extender Kit is included for some wiring situations

   Cons:

   • Door/window-based HVAC auto-pause requires a paid Smart Security subscription
   • Some installations depend on wiring conditions or the included Power Extender Kit
   • Humidity detection is listed, but specific control behavior is not detailed

   Best for: Households that want humidity detection and included room and door/window sensors without assembling a sensor bundle separately.

   Not ideal for: Buyers who want every sensor feature available without a subscription or who need explicit details on humidity-based control.

   • Model:ecobee3 Lite, EB-STATE3LTVP2-01 bundle
   • Connectivity:Wi-Fi
   • Power:24 volts AC/DC
   • Display:LCD
   • Humidity feature:Humidity detection
   • Included sensors:SmartSensor and Door and Window Sensor
   • Mobile compatibility:Android and iOS
   • Included installation components:Power Extender Kit, backplate, trim plate, install guide, wire labels, drywall plugs, screws
   Our verdict

   “Choose this ecobee bundle if included room and entry sensors matter alongside humidity detection, and accept the subscription condition for door/window auto-pause.”

   → See it on Amazon →

5. Honeywell Home T9 WiFi Smart Thermostat

   

   Best for Multi-Room Scheduling

   View Latest Price

   The Honeywell Home T9 is aimed at households that want to steer comfort by room and by whether anyone is home. Its smart room sensor support and geofencing give it a different emphasis from the ecobee3 Lite bundle: the T9 can build a multi-room setup, while the ecobee bundle includes a room sensor and a door/window sensor in the package. The T9 also provides a touchscreen, energy reports, and utility reward integration. However, the supplied product details do not identify a humidity sensor, so it is not as strong a match for a humidity-specific shortlist as either ecobee. Compatibility is another dividing line: it supports several forced-air and hydronic systems but excludes 120–240 V electric baseboard heat. Room sensors are sold separately, and many installations need a C-wire.

   Pros:

   • Supports smart room sensors for targeted multi-room comfort
   • Geofencing can adjust settings based on household location
   • Graphical touchscreen with Alexa and Google Assistant support
   • Includes energy reporting and utility reward integration

   Cons:

   • Product details do not specify a humidity sensor
   • Room sensors are sold separately
   • Incompatible with 120–240 V electric baseboard heat
   • Many installations require a C-wire or adapter

   Best for: Households with compatible central HVAC that want geofencing and the option to add room sensors for multi-room comfort.

   Not ideal for: Owners of 120–240 V electric baseboard systems or buyers who require documented humidity sensing.

   • Model:Honeywell Home T9
   • Connectivity:Wi-Fi
   • Display:Graphical LCD touchscreen
   • Power:24 V system with two AAA backup batteries
   • Compatible HVAC:Forced air (gas, oil, electric), hot water, steam, heat pumps
   • Incompatibility:120–240 V electric baseboard heat
   • Voice assistants:Alexa, Google Assistant
   • Room sensor support:Smart room sensors supported; sold separately
   Our verdict

   “Choose the T9 for geofencing and expandable multi-room comfort on a compatible system, but not if humidity sensing is a requirement.”

   → See it on Amazon →

6. Honeywell Home X8S Smart Wi-Fi Thermostat with Room Sensor, Black

   

   Best for Room-by-Room Comfort

   View Latest Price

   The X8S is my pick for households where the thermostat’s hallway reading misses what is happening in bedrooms or other frequently used spaces. Its included wireless room sensor can inform comfort adjustments from up to 200 feet away, giving it a more targeted approach than the X2S, which has no included room sensor. The 5-inch touchscreen also offers more space for controls than the X7S’s 4.3-inch display, while humidity and occupancy features add context to heating and cooling decisions. Matter support and compatibility with major voice platforms make it a flexible fit for connected homes. The tradeoffs are a required C-wire and no support for electric baseboard heat; video doorbell streaming also depends on a compatible, separately obtained device.

   Pros:

   • Included wireless room sensor supports more targeted comfort control
   • Large customizable 5-inch touchscreen
   • Humidity and occupancy features support comfort and energy-saving adjustments
   • Matter, Alexa, Google Assistant, and Apple Home compatibility

   Cons:

   • Requires a C-wire, with an adapter potentially needed
   • Does not support 120–240V electric baseboard heat
   • Doorbell streaming requires compatible equipment that may be purchased separately

   Best for: Households with rooms that run warmer or cooler than the thermostat location and buyers who want an included remote sensor.

   Not ideal for: Homes heated by 120–240V electric baseboard systems or buyers who cannot provide a C-wire.

   • Display:5-inch customizable touchscreen
   • Connectivity:Wi-Fi, 2.4 or 5 GHz
   • Included sensor:Wireless room sensor, range up to 200 ft
   • System compatibility:Up to 3 heat/2 cool heat pump with electric backup, or 2 heat/2 cool conventional
   • Smart home compatibility:Matter, Amazon Alexa, Google Assistant, Apple Home
   • Power:29 volts; C-wire required
   • Certification:ENERGY STAR
   • Doorbell compatibility:First Alert VX1 and Ring streaming doorbells
   Our verdict

   “Choose the X8S if an included room sensor matters more than a simpler thermostat or a lower-profile feature set.”

   → See it on Amazon →

7. Honeywell Home X2S Smart Wi-Fi Thermostat

   

   Best for Simple Scheduling

   View Latest Price

   The X2S suits buyers who want connected scheduling without the extra screens, room sensors, or air-quality detail found on models such as the ElitePRO S1200. It handles the basics that can make a thermostat easier to live with: flexible schedules, auto-away, and filter reminders, with Matter support for linking it to a compatible smart home. Its humidity feature is described as an optional indoor humidity display, so I would treat it as a basic awareness tool rather than the deeper humidity and air-quality monitoring offered by the ElitePRO S1200. The LCD and button controls keep the interface straightforward, and interchangeable accent pieces offer a small appearance choice. The main compromises are the required C-wire and the lack of electric baseboard compatibility; it also lacks the X8S’s included room sensor.

   Pros:

   • Flexible scheduling and auto-away support routine temperature changes
   • Matter and major smart-home platform compatibility
   • Filter reminders help prompt routine HVAC maintenance
   • Interchangeable white and gray accent pieces

   Cons:

   • Requires a C-wire with 24 VAC power
   • Does not work with 120–240V electric baseboard heat
   • Humidity display is more limited than the monitoring on the ElitePRO S1200

   Best for: Buyers with compatible forced-air or heat-pump systems who want app-based schedules, auto-away, and basic humidity visibility.

   Not ideal for: People seeking an included room sensor, a large touchscreen, detailed indoor air-quality tracking, or electric baseboard compatibility.

   • Display:LCD
   • Connectivity:Wi-Fi, 2.4 or 5 GHz, and Matter
   • Control:App and button control
   • System compatibility:Up to 2 heat/2 cool conventional or 2 heat/1 cool heat pump
   • Smart home compatibility:Amazon Alexa, Google Assistant, and Apple HomeKit
   • Power:24 VAC; C-wire required
   • Humidity feature:Optional indoor humidity display
   • Warranty:2 years
   Our verdict

   “Pick the X2S for straightforward schedules and basic humidity visibility, but choose a sensor-equipped model for more room-specific control.”

   → See it on Amazon →

8. Honeywell Home X7S Smart Wi-Fi Programmable Thermostat

   

   Best for a Touchscreen Interface

   View Latest Price

   The X7S is a strong match for buyers who want humidity monitoring and a visible, customizable control surface without moving up to the X8S’s larger 5-inch screen and included room sensor. Its 4.3-inch touchscreen gives schedules and temperature settings more room than the X2S’s LCD, while occupancy detection and auto-scheduling can reduce unnecessary heating or cooling when the home is empty. It also works with Matter, Alexa, Google Assistant, and Apple Home, so voice and app control are available alongside touch. Compared with the X7B, the listed feature set explicitly includes occupancy detection and auto-scheduling, making this the more feature-defined choice of the two. It still needs a C-wire and Wi-Fi, and humidity-related functions may depend on additional HVAC equipment or accessories.

   Pros:

   • Customizable 4.3-inch touchscreen
   • Humidity monitoring with occupancy detection and auto-scheduling
   • Matter and major voice-assistant compatibility
   • ENERGY STAR certified

   Cons:

   • Requires a C-wire; an adapter may be needed
   • Not compatible with 120–240V electric baseboard heat
   • Some humidity features may require additional HVAC equipment or accessories

   Best for: Smart-home households that want a customizable touchscreen, humidity monitoring, and occupancy-aware scheduling on a compatible HVAC system.

   Not ideal for: Homes with electric baseboard heat, no C-wire, or buyers who want a room sensor included in the box.

   • Display:4.3-inch customizable touchscreen
   • Connectivity:Wi-Fi, 2.4 or 5 GHz
   • Control:App, touchscreen, and voice
   • System compatibility:Up to 3 heat/2 cool heat pump with electric backup, or 2 heat/2 cool conventional
   • Smart home compatibility:Matter, Amazon Alexa, Google Assistant, Apple Home
   • Features:Occupancy detection, humidity monitoring, auto-scheduling, programmable temperature control
   • Power:Hardwired; C-wire required
   • Certification:ENERGY STAR
   Our verdict

   “Choose the X7S if touchscreen control and occupancy-aware humidity monitoring matter more than the X8S’s larger display and included room sensor.”

   → See it on Amazon →

9. Honeywell Home ElitePRO S1200 Smart WiFi Thermostat

   

   Best for Indoor Air-Quality Monitoring

   View Latest Price

   The ElitePRO S1200 earns its place for buyers who want humidity readings as part of a broader view of indoor air, not as an isolated number. It tracks humidity, VOCs, and estimated CO₂ levels, a wider monitoring brief than the X7S’s listed humidity monitoring. That added information may help buyers make more informed ventilation decisions, while the 5-inch touchscreen, Matter support, and compatible doorbell video add convenience at the wall. Its unusually broad stated HVAC support—including heat pumps, dual-fuel, radiant, PTAC, and fan-coil systems—also sets it apart from the more narrowly specified X8S. The tradeoff is complexity: the advanced system compatibility can make installation less approachable, and a C-wire is required. Buyers who only want humidity monitoring and routine scheduling may find the X2S simpler.

   Pros:

   • Tracks humidity, VOCs, and estimated CO₂ levels
   • 5-inch customizable touchscreen
   • Broad stated compatibility across several HVAC system types
   • Matter, major voice assistants, and compatible doorbell video support

   Cons:

   • Requires a hardwired C-wire
   • Advanced HVAC support may make setup more complex
   • Doorbell video depends on compatible equipment

   Best for: Owners of supported advanced HVAC systems who want humidity alongside VOC and estimated CO₂ monitoring.

   Not ideal for: Buyers seeking a simple humidity-and-scheduling thermostat, or anyone without a C-wire or confidence in advanced HVAC setup.

   • Display:5-inch touchscreen
   • Air-quality monitoring:Humidity, VOCs, and estimated CO₂
   • Connectivity:Bluetooth, RedLINK 3.0, and Wi-Fi on 2.4 and 5 GHz
   • Control:App, touch, and voice
   • HVAC compatibility:Heat pumps, dual-fuel, radiant, PTAC, and fan-coil systems
   • Power:Hardwired; C-wire required
   • Mounting:Wall mount
   • Dimensions:0.96 in D × 5.24 in W × 3.54 in H
   Our verdict

   “Choose the ElitePRO S1200 if you want humidity as part of broader air-quality monitoring and can handle a more involved installation.”

   → See it on Amazon →

10. Honeywell Home X7B Smart Wi-Fi Programmable Thermostat

    

    Best for Matter-Compatible Basics

    View Latest Price

    The X7B is a straightforward route to a touchscreen thermostat with humidity monitoring and Matter connectivity. It shares the X7S’s 4.3-inch customizable display and broad stated HVAC compatibility, but the supplied details do not list the X7S’s occupancy detection or auto-scheduling. That makes the X7B a better fit for buyers who want clear local controls and app or voice access without relying on those specific automation features. Compared with the X2S, it offers a larger touchscreen and explicitly lists humidity monitoring rather than an optional humidity display. It is ENERGY STAR certified, but buyers still need a C-wire and a compatible system; some features may require extra HVAC equipment or accessories, and electric baseboard heat is unsupported.

    Pros:

    • Customizable 4.3-inch touchscreen
    • Humidity monitoring with app, touch, and voice control
    • Matter and compatibility with Alexa, Google Assistant, and Apple Home
    • ENERGY STAR certified; C-wire adapter voucher included

    Cons:

    • C-wire is required even if an adapter is needed
    • Does not support 120–240V electric baseboard heat
    • Some features may need additional HVAC equipment or accessories

    Best for: Homeowners with compatible conventional or heat-pump systems who want a customizable touchscreen, humidity monitoring, and Matter-enabled control.

    Not ideal for: People with electric baseboard heating, no C-wire, or buyers prioritizing an included room sensor or listed occupancy detection.

    • Display:4.3-inch customizable touchscreen
    • Connectivity:Wi-Fi and Matter
    • Control:App, touchscreen, and voice
    • Compatible assistants:Amazon Alexa, Google Assistant, Apple Home
    • HVAC compatibility:Up to 3 heat/2 cool heat pump with electric backup, or 2 heat/2 cool conventional
    • Power:24 volts; hardwired; C-wire required
    • Wi-Fi requirements:2.4 or 5.0 GHz; 802.11ax/ac/a/b/g/n router
    • Certification:ENERGY STAR
    Our verdict

    “Pick the X7B for touchscreen humidity monitoring and Matter control, but favor the X7S if occupancy detection and auto-scheduling are priorities.”

    → See it on Amazon →

11. Honeywell Home X7S Smart Wi-Fi Programmable Thermostat, White

    

    Best for Smart-Home Flexibility

    View Latest Price

    The Honeywell Home X7S is a strong fit if you want humidity monitoring alongside broad smart-home support. Its 4.3-inch customizable touchscreen puts controls and readings on the wall, while occupancy detection can adjust settings when rooms are empty. You can also connect it through Matter, Apple Home, Alexa, or Google Assistant, giving it wider ecosystem choice than the Google Nest Thermostat, which centers more heavily on Google Home for app control.

    The tradeoff is installation flexibility: the X7S requires a C-wire and does not support 120–240V electric baseboard heat. Humidity monitoring is included, but some humidity-related functions may depend on extra HVAC equipment or accessories. I’d choose it for a compatible 24-volt system where touchscreen customization and cross-platform control matter more than a simpler installation.

    Pros:

    • Humidity monitoring adds indoor moisture awareness to temperature control
    • Matter, Apple Home, Alexa, and Google Assistant support offers broad ecosystem choice
    • Customizable 4.3-inch touchscreen makes on-wall controls easy to tailor
    • Occupancy detection can adjust settings when the home is unoccupied

    Cons:

    • Requires a C-wire for power
    • Does not support 120–240V electric baseboard heating
    • Some humidity features may need additional HVAC equipment or accessories

    Best for: Households with compatible 24-volt HVAC, an available C-wire, and devices across multiple smart-home ecosystems

    Not ideal for: Homes with electric baseboard heating or no C-wire that want to avoid wiring changes or added accessories

    • Display:4.3-inch customizable touchscreen
    • Connectivity:Wi-Fi, 2.4 or 5 GHz
    • Voltage:24 volts
    • Humidity feature:Indoor humidity monitoring
    • Occupancy feature:Occupancy detection
    • System compatibility:Up to 3 heat/2 cool heat pump or 2 heat/2 cool conventional systems
    • Smart-home support:Matter, Amazon Alexa, Google Assistant, Apple Home
    • Power requirement:C-wire required
    • Certification:ENERGY STAR
    Our verdict

    “Choose the X7S if you have compatible wiring and want humidity monitoring with a customizable display and broad smart-home compatibility.”

12. ecobee Smart Thermostat Essential

    

    Best for Flexible HVAC Compatibility

    View Latest Price

    The ecobee Smart Thermostat Essential suits buyers who want indoor humidity detection and scheduling across a broad range of common HVAC types. Its stated compatibility includes systems such as boilers, dual fuel, and heat pumps, while auto-away and auto-scheduling can reduce unnecessary heating or cooling when routines change. Compared with the Honeywell Home X7S, it offers a smaller display and a more basic feature set, but its listed system range makes it a useful alternative for varied household equipment.

    Power planning is the main compromise. Although the thermostat is described as battery powered, some installations may need a separately sold Power Extender Kit; a trim kit is also sold separately. The 3.74-inch touchscreen and app provide straightforward control, but buyers seeking a large, highly customizable wall interface may prefer the X7S. I’d shortlist this ecobee when HVAC compatibility and everyday humidity awareness take priority over an elaborate display.

    Pros:

    • Indoor humidity detection adds moisture information to everyday comfort control
    • Supports a broad range of listed 24 VAC HVAC system types
    • Auto-away and auto-scheduling can adapt operation to household routines
    • Works with Apple HomeKit, Google Assistant, and Amazon Alexa

    Cons:

    • Some installations may require a separately sold Power Extender Kit
    • Trim kit is sold separately
    • Compatibility can vary by HVAC system

13. Google Nest Thermostat – Smart Programmable Wi-Fi Thermostat (Charcoal)

    

    Best for Simple DIY Energy Scheduling

    View Latest Price

    The Google Nest Thermostat is the straightforward pick here for buyers who value DIY setup, automatic away adjustments, and HVAC alerts more than a clearly specified humidity-monitoring feature. Its ENERGY STAR certification and Google Home app scheduling make routine temperature control accessible, while HVAC monitoring can flag potential system issues. Compared with the ecobee Smart Thermostat Essential and Honeywell Home X7S, the Nest has a smaller 2-inch display and its supplied feature details do not list indoor humidity detection. That makes it a less direct match for shoppers choosing specifically for humidity sensing.

    Installation is a draw for many homes: it typically takes about 30 minutes and often works without a C-wire. However, some heat-pump or zone-controlled systems need a C-wire or power accessory, and remote functions rely on a working internet connection. I’d choose it for simple scheduling and maintenance alerts, but look to the X7S or ecobee if humidity monitoring is a must-have.

    Pros:

    • DIY installation is described as typically taking about 30 minutes
    • Automatic away adjustments can help reduce heating or cooling when nobody is home
    • HVAC monitoring can alert users to potential system issues
    • Often works in homes without a C-wire

    Cons:

    • The supplied product details do not specify an indoor humidity sensor or humidity monitoring
    • Some heat-pump and zone-controlled systems require a C-wire or power accessory
    • Remote features depend on a working internet connection and Wi-Fi

    Best for: Google Home households seeking a compact, DIY thermostat for scheduling, away adjustments, and HVAC alerts

    Not ideal for: Buyers who specifically require documented indoor humidity monitoring or need reliable remote control without internet access

    • Display:2-inch LCD
    • Connectivity:Wi-Fi (2.4 GHz and 5 GHz) and Bluetooth Low Energy
    • Power source:Two included AA batteries
    • Voltage:24 volts
    • Smart-device compatibility:Google Assistant, Amazon Alexa, iOS, Android
    • App control:Google Home app
    • Monitoring feature:HVAC monitoring and potential system issue alerts

How We Picked

I ranked these thermostats by how well they fit the specific search for smart thermostats with humidity sensors, while separating humidity monitoring from broader comfort features. I weighed whether a model’s humidity information is useful alongside its controls, how readily it can address uneven temperatures with room sensors, and the clarity of its smart-home and app experience. I also considered display usability, setup demands, HVAC compatibility, and whether the feature set seems suited to a simple replacement or a more involved connected-home system.

The ranking favors a balanced combination of humidity awareness, usable controls, and flexibility over a long list of features alone. Products that offer distinct benefits for room sensing, simpler operation, or broader integrations remain useful alternatives, but they rank below models that better match the central humidity-focused need. Several Honeywell products have similar names, so I treat each listed version separately and recommend checking its exact specifications and wiring requirements before purchase.

Factors to Consider When Choosing Smart Thermostats With Humidity Sensors

Before choosing a model, I’d separate the comfort problem you want to solve from the features that happen to be advertised together. These checks can help prevent paying for room sensors or smart-home integrations you won’t use—or buying a humidity display that cannot control the equipment you have.

Decide Whether You Need Humidity Monitoring or Control

A humidity reading helps you understand indoor conditions, but it does not automatically mean the thermostat can operate a humidifier or dehumidifier. If your goal is simply to track moisture alongside temperature, monitoring may be enough. If you expect the thermostat to manage humidity, check that the specific model supports your equipment and the control behavior you want. HVAC systems vary, and accessory terminals or wiring may be required. A common mistake is assuming that a humidity sensor means automatic humidity regulation. Match the thermostat’s documented controls to your actual humidifier, dehumidifier, or HVAC setup before buying.

Check HVAC and Wiring Compatibility First

Smart features cannot make an incompatible thermostat work with an incompatible heating or cooling system. Identify whether you have conventional heating and cooling, a heat pump, or another setup, then check the thermostat’s compatibility guidance and wiring requirements. Some homes may need a C-wire or an approved power solution, and accessory equipment can add further requirements. Take a photo of the existing wiring and record the system type before removing the old thermostat. Don’t rely on a matching wire color alone, since wiring conventions and system configurations vary. If the documentation leaves uncertainty, confirm compatibility with the manufacturer or an HVAC professional before installation.

Treat Room Sensors and Humidity Sensors as Separate Tools

A humidity sensor reports moisture conditions, while remote room sensors help the thermostat account for temperature differences around the home. Those functions can complement each other, but one does not replace the other. If bedrooms are uncomfortable while the main thermostat area feels fine, room sensing may matter more to comfort than extra app controls. If your concern is dryness or dampness throughout the home, focus on where humidity is measured and what the thermostat can do with the reading. Check whether sensors are included or sold separately, and whether they measure temperature, occupancy, or other conditions. Buying a bundle without a clear use for its sensors can add complexity without solving the problem.

Choose Smart-Home Support Around Your Existing Setup

Compatibility with Alexa, Google Home, or Apple Home can shape daily use, but the label alone does not tell you which controls are available. Check whether your preferred platform can change temperature, access schedules, or use humidity information—or whether it offers only basic commands. Also check app requirements, account setup, and whether the features you want need another device or service. A household using one platform throughout may benefit from a thermostat that fits that system, while a mixed-device home may value broader support. Avoid choosing based only on a voice-assistant logo; confirm the specific integration you plan to use.

Match the Display and Controls to Your Household

A large touchscreen can make schedules and settings easier to adjust at the wall, while a simpler interface may suit someone who mostly uses an app. Consider who will operate the thermostat: guests, children, or household members who do not want to manage a phone app may appreciate clear physical controls and readable information. Look at whether the display surfaces humidity clearly or buries it in menus. A more elaborate interface can also mean more setup choices and a learning curve. Compare the on-device controls with the mobile app before deciding which style will be easier for everyday adjustments.

Pay for Features That Solve a Real Comfort Problem

Higher-feature models make more sense when you will use capabilities such as remote room sensing, expanded smart-home integration, or control of additional HVAC equipment. If you mainly need scheduled temperature adjustments and a humidity reading, a simpler thermostat may be a better fit. Factor in possible costs beyond the thermostat itself, including optional sensors, wiring changes, and professional installation. A feature-rich thermostat is not automatically a better choice if its extras do not match your home or routine. Decide which one or two problems you want the thermostat to solve, then compare models against those needs instead of buying by feature count.

Frequently Asked Questions

Does a thermostat with a humidity sensor automatically control a humidifier or dehumidifier?

No. A built-in humidity sensor may only report indoor moisture levels, while equipment control depends on the thermostat’s supported functions and wiring. Check the exact model documentation for humidifier or dehumidifier control, not just the presence of a humidity reading. Your HVAC system may also need compatible terminals or additional wiring. If you want automatic humidity management, confirm that both the thermostat and your equipment support the intended setup. When the wiring or system type is unclear, ask an HVAC professional to verify it before purchase.

Should I choose a thermostat with remote room sensors if it already measures humidity?

Choose remote room sensors if temperature varies noticeably between rooms or you want the thermostat to respond to conditions away from its wall location. A humidity sensor and a room sensor serve different purposes, so one does not make the other unnecessary. Check what each sensor measures and whether it is included, optional, or limited to certain thermostat functions. For a home with consistent temperatures, remote sensors may add little value. For bedrooms that feel much warmer or cooler than the hallway, room sensing may matter more to comfort than additional humidity displays.

How can I tell whether one of these thermostats will work with my HVAC system?

Start by identifying your heating and cooling system type and checking the thermostat’s compatibility chart and wiring requirements. Note the labels on your current thermostat terminals, but don’t assume wire colors alone confirm compatibility. Heat pumps, multi-stage systems, and humidity-control accessories can have requirements that differ from a basic furnace-and-air-conditioner setup. A missing C-wire may also affect installation or call for a supported power solution. If the model’s compatibility information does not clearly match your system, verify with the manufacturer or an HVAC professional before ordering.

Are the Honeywell Home X7S, X7B, X8S, and X2S interchangeable?

No; similar names are not a reliable guide to identical features. The listed models differ by version, and details such as display, included room sensor, and smart-home support can affect which one fits your home. Compare the exact product listing and manufacturer specifications rather than relying on a family name or a photo. Pay particular attention to whether a sensor is included and which HVAC systems are supported. If you are deciding between two versions, use the model number and full feature list as the basis for comparison.

When is it worth paying for a more feature-rich smart thermostat?

A more advanced model can make sense if you will use remote room sensing, broader smart-home controls, or support for additional HVAC equipment. It is less compelling when your main needs are a basic schedule and an at-a-glance humidity reading. Include any optional sensors, installation work, and wiring changes in your decision, since those can affect the total effort and system fit. Also think about who will adjust the thermostat and whether they will use its extra controls. Paying for features is most useful when they address a specific comfort issue you already have.

Conclusion

For the broadest balance of humidity awareness and connected-thermostat features, I’d start with the ecobee Smart Thermostat Enhanced as my best overall pick. The Sensi Smart Thermostat (ST55) is my value-oriented choice for buyers who want a simpler connected thermostat, while the Honeywell Home ElitePRO S1200 is the premium-style pick for shoppers drawn to a larger touchscreen and indoor air-quality monitoring. Beginners should compare the Google Nest Thermostat and Sensi options based on the setup and app experience they prefer, after checking HVAC compatibility. For homes with uneven room temperatures, look more closely at the Honeywell T9 or ecobee3 Lite bundle; choose the Sensi Touch 2 if a touchscreen is a priority. Before making a final choice, verify that your preferred model’s humidity function matches your goal—monitoring, equipment control, or both—and that it works with your wiring.
