If you’re searching for a smart thermostat with a Farsight display, the main choice here is between a newer model with a room sensor included and an older learning thermostat that focuses on automatic scheduling. My best overall pick is the 4th Gen Nest Learning Thermostat with Nest Temperature Sensor: Dynamic Farsight gives its large screen more at-a-glance utility, and the included sensor can help address uneven temperatures between rooms. The 3rd Gen Nest Learning Thermostat is the simpler alternative for buyers who want learned schedules, remote app access, and HVAC alerts without needing the newest screen or included sensor.

Both models aim to reduce hands-on thermostat adjustments, but they are not interchangeable. The 4th Gen has the clearer advantage if display visibility, room-by-room temperature awareness, and wider smart-home support matter most. The 3rd Gen may suit a household that values familiar Nest learning features and broad system compatibility, provided its display and sensor arrangement match the home. I’d check HVAC compatibility and installation requirements before choosing either; smart controls cannot make an incompatible system work.

Google Nest Learning Thermostat (4th Gen) with Nest Temperature Sensor (2nd Gen) – Obsidian
The 4th Gen takes the lead because its large, bright touchscreen and Dynamic Farsight directly answer the reason someone might search for a thermostat with a farsight display. The screen is designed to make temperature information more visible at a glance, rather than requiring the same level of close interaction as a basic control panel. Compared with the 3rd Gen, this is the more display-led choice and the more natural fit for a central hallway or another spot where household members regularly pass the thermostat.
Its second major advantage is what comes in the box: a 2nd Gen Nest Temperature Sensor. That gives the system another source of room temperature information, which can be useful when the thermostat’s location does not reflect conditions in a bedroom or living area. The 3rd Gen can work with a Nest Temperature Sensor too, but buyers need to purchase it separately. For a home with a recurring hot or cold spot, the 4th Gen bundle is a more complete starting point, though a sensor does not promise that every room will reach identical comfort.
Both products learn schedules and support app-based control, so I would not choose the newer thermostat solely for automatic programming. The 4th Gen separates itself through Dynamic Farsight, the included sensor, Matter compatibility, and listed support for Alexa, Siri, and Google Assistant. That broader integration may matter in a mixed-device home. Its main caveats are setup complexity for less technical buyers and the replaceable CR2 battery. The product information also says it works with most 24V HVAC systems; that is a useful starting point, not a substitute for checking your specific wiring and equipment.
Against the 3rd Gen, this is the pick for buyers who want the most capable display-focused package and room sensing without a separate sensor purchase. The 3rd Gen may be a better fit if you already use its generation of Nest features, want its stated 95% compatibility figure, or do not need a touchscreen-forward presentation. The 4th Gen’s advantage is clearest when screen visibility and multi-room temperature awareness are both priorities.
Pros:- Large, bright touchscreen with Dynamic Farsight.
- Includes a 2nd Gen Nest Temperature Sensor for tracking another room.
- Learns schedules and supports automatic away and scheduling features.
- Matter compatibility and listed Alexa, Siri, and Google Assistant support.
Cons:- Initial setup may be challenging for buyers without technical experience.
- The included CR2 battery will need periodic replacement.
- Compatibility is described for most 24V HVAC systems, so individual system checks are still needed.
Best for: Households prioritizing a large Farsight-style display, included room sensing, and compatibility with a broad mix of smart-home platforms.
Not ideal for: Buyers who prefer a straightforward setup, do not need an additional room sensor, or have not confirmed their 24V HVAC system and wiring compatibility.

Our verdict“I’d choose the 4th Gen for the most complete Farsight-focused package, especially when an included room sensor and broader smart-home support are useful.”
Google Nest Learning Thermostat, 3rd Gen, Mirror Black
The 3rd Gen is the better fit for buyers who want a learning thermostat with remote control and HVAC alerts but do not need the 4th Gen’s Dynamic Farsight screen. It learns preferred temperatures and daily patterns, then builds a schedule intended to reduce repetitive manual changes. Home/Away Assist, Energy History, and alerts add practical tools for managing heating and cooling from the Nest app. These functions keep it relevant, even though the 4th Gen is the stronger match for a display-first search.
Its clearest advantage in this pairing is the stated compatibility with 95% of heating and cooling systems. That figure gives the 3rd Gen a broader stated reach than the 4th Gen’s description of working with most 24V systems, although neither description can confirm compatibility with an individual furnace, heat pump, or wiring arrangement. I would check the manufacturer’s compatibility guidance before buying. The thermostat is hardwired at 24 volts and lists Wi-Fi, Bluetooth Low Energy, and 802.15.4 wireless interconnect.
On the display question, the 3rd Gen has a bright digital screen, but the supplied product details do not specify Dynamic Farsight. That makes it a less direct choice than the 4th Gen for someone who wants information to stand out from across a room. It also lacks the newer model’s listed Matter support and broader specified voice-platform range. While it can pair with a Nest Temperature Sensor, that accessory is sold separately; buyers managing an uncomfortable room should account for that extra step in the setup.
Compared with the 4th Gen bundle, this model suits someone who values familiar learning and monitoring tools over the newest display and included sensor. Its remote features depend on a working internet connection and Wi-Fi, so a network problem can limit app-based control and notifications. I would choose it for a home where its compatibility and learning features are the deciding factors, not for a buyer who specifically wants the most explicit Farsight display experience.
Pros:- Learns preferred temperatures and routines to create a schedule.
- Includes remote control, Home/Away Assist, Energy History, and HVAC alerts.
- Product details state compatibility with 95% of heating and cooling systems.
- Supports an optional Nest Temperature Sensor.
Cons:- Nest Temperature Sensor is sold separately.
- Remote control and notifications require working internet and Wi-Fi.
- The supplied description does not specify Dynamic Farsight or Matter compatibility.
Best for: Nest users seeking learned schedules, app control, Home/Away Assist, Energy History, and a model with a stated 95% HVAC compatibility figure.
Not ideal for: Buyers who want Dynamic Farsight, an included room sensor, Matter support, or a display that is explicitly described as a large touchscreen.
- Generation:3rd generation
- Color:Mirror Black
- Display:Digital, bright display
- HVAC compatibility:Works with 95% of heating and cooling systems, according to the product description
- Connectivity:Wi-Fi, Bluetooth Low Energy, and 802.15.4 wireless interconnect
- Wi-Fi bands:2.4 GHz and 5 GHz
- Power:Hardwired, 24 volts
- Controls and assistants:App, voice, and remote control; Google Assistant and Amazon Alexa
Our verdict“I’d pick the 3rd Gen when its learning tools and stated broad HVAC compatibility matter more than Dynamic Farsight and an included room sensor.”
How We Picked
I ranked these two thermostats by how well they meet the specific promise of a smart thermostat with a Farsight display, then weighed the practical differences that affect a household’s choice. Display readability and at-a-glance usefulness come first: the 4th Gen explicitly features a large, bright touchscreen with Dynamic Farsight, while the 3rd Gen is described as having a bright digital display without the same Dynamic Farsight feature specified.
I also compared what buyers get for managing temperature beyond the main thermostat. The 4th Gen package includes a 2nd Gen temperature sensor, a meaningful distinction for homes where one room regularly runs warmer or cooler. The 3rd Gen supports a Nest Temperature Sensor, but it is sold separately. Next, I looked at learning and remote-control capabilities, HVAC compatibility, connectivity, and smart-home support. The 3rd Gen has a stated 95% heating and cooling system compatibility figure; the 4th Gen is described as compatible with most 24V HVAC systems. Those descriptions are not identical, so I would verify the exact system rather than assume either is a match.
Finally, I considered setup and ongoing tradeoffs, including Wi-Fi dependence, wiring or power needs, and the 4th Gen’s replaceable CR2 battery. I have not treated energy-saving claims as guaranteed results: actual outcomes depend on the home, equipment, schedule, and settings. Because there are only two products in this comparison, the ranking reflects which better fits the Farsight-display brief, not a claim that the older model lacks value.

Factors to Consider When Choosing Smart Thermostat With Farsight Display
The right choice depends on how much you value the display itself compared with room sensing, system fit, and smart-home integration. I’d use the following checks to separate the two.Decide what Farsight needs to do for you
The 4th Gen is the straightforward pick if Dynamic Farsight and a large touchscreen are the features that brought you here. The screen is the most visible distinction between these products. The 3rd Gen has a bright digital display, but its supplied details do not identify the Dynamic Farsight feature. If you want a thermostat whose display is a prominent part of the experience, the newer model better matches that brief. If you mainly need app control and learned schedules, the older model’s display may be sufficient.
Check HVAC compatibility and wiring before ordering
The 3rd Gen listing gives a specific compatibility figure of 95% of heating and cooling systems; the 4th Gen description says it works with most 24V HVAC systems and often does not need a C-wire. These are useful screening details, not a system-by-system guarantee. Identify your heating and cooling equipment, inspect the existing thermostat wiring, and use the manufacturer’s compatibility checker or installation guidance. If you are unsure about the wiring, asking a qualified installer can prevent an avoidable setup problem.
Treat the included sensor as a real difference
The 4th Gen package includes a 2nd Gen Nest Temperature Sensor, while the 3rd Gen can use a compatible sensor purchased separately. A second measurement point can help the thermostat account for a room that differs from the thermostat’s location. Think about where your household spends time and whether one room is regularly too warm or too cool. If the temperature is consistent across your home, the included sensor may matter less; if a known hot or cold spot is a concern, the bundle offers a more ready-to-use solution.
Match smart-home support to the devices you already own
The 3rd Gen lists Google Assistant and Amazon Alexa support. The 4th Gen lists Alexa, Siri, Google Assistant, and Matter compatibility, giving it a broader stated range for a mixed smart-home setup. Check which voice assistant or platform you actually use before paying attention to compatibility claims. A wider list only helps when it fits your existing devices and preferred controls. Both products offer app-based control, while the 3rd Gen specifically calls out Nest app functions such as Energy History and HVAC alerts.
Weigh power, setup, and internet dependence
The 3rd Gen is described as hardwired at 24 volts. The 4th Gen is also listed at 24 volts and includes a CR2 battery that needs periodic replacement. The 4th Gen product information notes that initial setup may be challenging for less technical users; the 3rd Gen listing describes typical installation as 30 minutes or less. Installation time varies with wiring and system conditions. Also, the 3rd Gen’s remote control and notifications require a working internet connection and Wi-Fi, so distinguish local thermostat operation from connected features when planning your setup.
Frequently Asked Questions
Which thermostat is the better choice for a Farsight display?
I’d choose the 4th Gen Nest Learning Thermostat. Its listed large touchscreen includes Dynamic Farsight, while the 3rd Gen is described as having a bright digital display without Dynamic Farsight specified. The 3rd Gen can still suit someone who wants learning and app features more than a display-led experience.
Does the 4th Gen include a room temperature sensor?
Yes. This 4th Gen package includes a 2nd Gen Nest Temperature Sensor. The 3rd Gen supports a Nest Temperature Sensor too, but that sensor is sold separately. A room sensor can provide another temperature reading for a room that differs from the thermostat’s location, though it does not guarantee identical temperatures throughout the home.
Will either thermostat work with my heating and cooling system?
The 3rd Gen product details state compatibility with 95% of heating and cooling systems. The 4th Gen is described as working with most 24V HVAC systems. Those summaries do not confirm a specific installation. Check your system type and thermostat wiring against the manufacturer’s compatibility information before choosing, and get installation help if the wiring is unclear.
Do both models learn my schedule?
Both are described as learning schedules or preferred temperatures and adjusting heating and cooling around those patterns. The 3rd Gen also lists Home/Away Assist, Energy History, and HVAC alerts. The 4th Gen lists automatic scheduling and away features. Learning behavior can reduce routine manual changes, but the result depends on how you use the thermostat and the conditions in your home.
Which model is better for a mixed smart-home setup?
The 4th Gen has the broader stated smart-home support in this comparison: its listing includes Matter, Alexa, Siri, and Google Assistant. The 3rd Gen lists Google Assistant and Amazon Alexa. I’d check that your existing devices and preferred platform support the control features you want; platform compatibility alone does not mean every function works in every setup.
Conclusion
For the buyer who searched specifically for a smart thermostat with a Farsight display, I recommend the 4th Gen Nest Learning Thermostat with the included 2nd Gen Temperature Sensor. It pairs Dynamic Farsight with a large touchscreen, adds another room temperature reading, and lists broader smart-home support. Pick it if those display and sensing benefits justify a more involved setup.
Choose the 3rd Gen Nest Learning Thermostat if you want learned schedules, app control, Home/Away Assist, Energy History, and the product’s stated 95% system compatibility figure, but do not need Dynamic Farsight or a sensor in the box. For either model, check your HVAC equipment and wiring before purchase. My short version: 4th Gen for display and included room sensing; 3rd Gen for established Nest learning features and its stated broad compatibility.
