Google Nest Learning Thermostat (4th gen) + Nest Temperature Sensor (2nd gen) – Obsidian
Best Nest Thermostat Black Friday Deals 2026
A Nest thermostat can suit different priorities: straightforward app-based scheduling, a learning thermostat that adapts to your routine, or room-by-room temperature planning with an included sensor. This Black Friday guide compares the listed models by their documented features, so you can focus on what would matter in your home rather than assuming a sale makes one option right for everyone. Before deciding, check the exact product name and finish, review the offer shown for that listing, and confirm that the thermostat is compatible with your heating and cooling system. The right choice depends on the controls you want, your system’s wiring, and whether remote adjustments or a separate room sensor are useful to you.
Google Nest Thermostat – Snow
The Google Nest Thermostat in Snow is the simpler option here for shoppers who want app-based scheduling and remote temperature changes. You can program an energy-efficient schedule in the Google Home app on an Android phone or iPhone, and family members can adjust the temperature remotely from a phone, laptop, or tablet. That gives household members a way to make a change while away without relying on the thermostat’s schedule alone. Wi-Fi connectivity is listed, and voice-assistant compatibility includes Google Assistant and Matter-certified voice assistants. Voice control requires a compatible smart device, so consider what you already use before treating voice commands as part of your setup.
Its wiring qualification deserves attention before you buy. The thermostat is designed to work without a C wire in most homes, but some systems—including heating-only, cooling-only, zone-controlled, and heat-pump systems—need a C wire or another compatible power accessory. Check your system details rather than assuming that “most homes” covers your installation. If the wiring situation is uncertain, resolving that question before Black Friday shopping can help you avoid choosing an offer that is not appropriate for your setup.
This model earns the Best Budget label among the products in this guide because it offers scheduled app control and remote adjustments without the listed learning features or included temperature sensor of the other options. That is a comparison of the features provided here, not a claim about sale price or measured value. On Black Friday, compare the exact Snow listing and offer with the other Nest models, and decide whether scheduled control is enough for your household. If you specifically want the included second-generation sensor or a thermostat that learns your schedule, look at the other choices instead.

Google Nest Learning Thermostat (4th gen) + Nest Temperature Sensor (2nd gen) – Obsidian
Check Price on Amazon
The Google Nest Learning Thermostat (4th gen) with Nest Temperature Sensor (2nd gen), in Obsidian, is the most complete match here for shoppers who want to coordinate temperatures across rooms and use several kinds of control. The included sensor can go in a room of your choice, and the Google Home app lets you set the temperature that room should reach at a particular time of day. That can be useful when your preferred temperature depends on the room you use or the time of day. Since the sensor is included with this listed bundle, compare the exact bundle name when reviewing Black Friday offers rather than treating every thermostat listing as the same package.
The thermostat works with most 24V systems, including gas, electric, oil, forced air, heat pump, and radiant systems. A C wire is not required for installation in most homes, but “most” is an important qualification: confirm compatibility with your own system before buying. The listing also describes the thermostat as easy to install yourself and Matter compatible for smart-home integration. You can adjust it on your phone from anywhere or use voice control with an Alexa, Siri, or Google Assistant smart speaker. Check which devices and control methods you intend to use when comparing offers.
Its away-temperature feature uses the outdoor temperature to help find an energy-saving temperature when you are away, then returns to a comfortable temperature within an hour of your return. Those functions, the included sensor, and the app’s room-temperature scheduling support its Best Overall label among the listed options. That label reflects the breadth of the supplied features, not a test result or a guarantee that it is right for every system. During Black Friday, weigh those added controls against your actual needs: if you only want a basic schedule, the Snow model may be a more fitting choice; if room-specific scheduling appeals to you, this bundle brings that capability together with the thermostat.
Key specs
| System compatibility | works with most 24V systems, including gas, electric, oil, forced air, heat pump, and radiant, and no C wire is required for installation in most homes |
| App and voice control | Adjust on your phone from anywhere[1] or by using your voice with Alexa, Siri, or Google Assistant smart speaker[3] |
| Smart home support | it’s easy to install yourself and it’s Matter compatible for simple integration into your smart home[5] |
| Included sensor | it comes with the Nest Temperature Sensor (2nd gen) |
| Room temperature scheduling | put a sensor in any room and use the Google Home app to set the temp it should reach at a certain time of day |
| Away temperature adjustment | It uses the temperature outside to help find an energy-saving temperature when you’re away and returns to a comfortable temperature within an hour of your return[1] |
Google Nest Learning Thermostat – 3rd Gen – Programmable Smart Thermostat for Home – Compatible with Alexa (Stainless Steel)
Check Price on Amazon
The Google Nest Learning Thermostat (3rd gen) in Stainless Steel is a distinct option for someone who wants the thermostat to learn a routine. It learns your schedule and preferred temperatures, then programs itself. Its Home/Away Assist feature automatically adjusts to an Eco Temperature after you leave. Together, those features make this a useful model to consider if you would rather have the thermostat build a schedule from your habits than enter every scheduled temperature yourself. The Best for Learning a Schedule label describes that specific feature set, not a claim that this model outperforms the other products.
Remote control lets you change the temperature from anywhere using a phone, laptop, or tablet. Energy History lets you check how much energy you used and why on your phone, while HVAC monitoring looks out for heating and cooling systems and sends an alert if something does not seem right. These details may matter if you want remote adjustment, a view of energy use, and system alerts in the same thermostat. It also works with the Nest Temperature Sensor, which is sold separately; unlike the 4th gen bundle in this guide, the sensor is not listed as included with this product.
The listing identifies this Stainless Steel model as compatible with Alexa, but the facts provided here do not establish the wiring requirements or broader system compatibility. Check the exact listing and your system details before making a purchase, especially if wiring is a deciding factor. For Black Friday, compare this 3rd gen model with the 4th gen Obsidian bundle by looking at the features you will actually use: self-programming and Energy History here, versus the included sensor and room-temperature scheduling in the bundle. Check that the offer applies to this exact generation and finish, rather than assuming a deal on one Nest model carries over to another.
Key specs
| Scheduling | learns your schedule and the temperatures you like and programs itself |
| Home/Away Assist | automatically adjusts itself to an Eco Temperature after you leave |
| Remote control | remote control lets you change the temperature from anywhere on your phone, laptop, or tablet[1] |
| Energy history | With Energy History, just check your phone to see how much energy you used and why |
| HVAC monitoring | looks out for your heating and cooling systems; sends an alert if something doesn’t seem right |
| Temperature sensor compatibility | works with the Nest Temperature Sensor (sold separately) |
How to compare Nest thermostat Black Friday offers
Start by matching the offer to the exact product, generation, finish, and bundle. The products here are not interchangeable packages: the 4th gen Learning Thermostat listing includes a second-generation Nest Temperature Sensor, while the 3rd gen model works with a sensor sold separately. The Snow thermostat has its own scheduling and remote-control features. A Black Friday offer should be judged against the item actually shown, not against a similarly named Nest thermostat or a different bundle.
Next, compare the features that change how you would use the thermostat. Ask whether you want to set a schedule yourself, have the thermostat learn one, or set a room’s temperature using a separate sensor. Consider whether remote adjustment, voice control, Energy History, or HVAC alerts would be useful to you. These are practical differences supported by the listed features; they do not establish that one model is universally better. Check the current offer details for the exact item, and do not assume a promotion or package based on the category name alone.
Check your heating system and wiring before Black Friday
Compatibility should be a decision point before price. The Snow model is designed to work without a C wire in most homes, but the listing names several exceptions: heating-only, cooling-only, zone-controlled, and heat-pump systems may need a C wire or another compatible power accessory. The 4th gen Learning Thermostat works with most 24V systems, including gas, electric, oil, forced air, heat pump, and radiant, and likewise does not require a C wire in most homes. Those qualifications make it important to check your own equipment rather than reading “no C wire” as a guarantee.
For the 3rd gen Learning Thermostat, the supplied facts do not specify system compatibility or C-wire requirements. Do not fill that gap by assuming it has the same requirements as another model. Confirm the details for the exact listing and your system before buying. If you are considering a Black Friday offer, make compatibility part of your comparison alongside the price displayed for that offer. A thermostat that does not fit your installation is not the right choice just because its feature list looks appealing.
Choose between a manual schedule and learning features
Think about how much schedule setup you want to do. With the Snow thermostat, you can program an energy-efficient schedule in the Google Home app. That approach lets you enter a schedule yourself. By contrast, the 3rd gen Learning Thermostat learns your schedule and the temperatures you like, then programs itself. Its Home/Away Assist feature also adjusts to an Eco Temperature after you leave. Consider which approach sounds more convenient for your household rather than assuming that learning features are necessary.
The 4th gen Learning Thermostat also has specific temperature-setting options through its included sensor: place the sensor in a room, then use the Google Home app to set the temperature it should reach at a certain time of day. This is different from simply choosing a schedule for the thermostat, so decide whether room-specific planning addresses a real need. During Black Friday comparisons, make a short list of the controls you would use regularly. That can make it easier to avoid paying attention to a feature you do not need or overlooking one that matters to your daily routine.
Consider sensors, remote control, and smart-home use
The sensor distinction is straightforward but important: the 4th gen Obsidian bundle includes a Nest Temperature Sensor (2nd gen), and the 3rd gen Stainless Steel thermostat works with a Nest Temperature Sensor sold separately. The Snow model’s listed facts do not describe a sensor, so compare only what is confirmed for the exact listing. If room-temperature scheduling is a priority, the included sensor and app feature make the 4th gen bundle the relevant option among these products. If you do not expect to use a sensor, that bundle detail may be less important to your decision.
Remote access and voice control also differ across the supplied descriptions. The Snow and 3rd gen models list remote temperature changes from a phone, laptop, or tablet. The 4th gen lists phone adjustments from anywhere and voice control with Alexa, Siri, or a Google Assistant smart speaker; it is also Matter compatible. The Snow is compatible with Google Assistant and Matter-certified voice assistants, with voice control requiring a compatible smart device. Check which devices you already use and confirm the exact listing details when shopping Black Friday offers.
Match the feature set to everyday priorities
For a simple app-programmed schedule and remote adjustments, the Snow model has a focused set of listed features. For a thermostat that learns preferred temperatures and programs itself, the 3rd gen Learning Thermostat is the one to examine. For an included sensor and app-based room-temperature scheduling, consider the 4th gen bundle. These are different routes to managing temperatures, not a ranking of how well each will perform in a particular home. Your system, household habits, and preferred controls should lead the decision.
The additional information on the learning models may influence your choice too. The 3rd gen offers Energy History and HVAC alerts, while the 4th gen describes an away-temperature adjustment using the temperature outside and a return to a comfortable temperature within an hour of your return. Those features address different interests; do not assume one model includes the other’s functions unless its listing says so. On Black Friday, compare the exact item and the features attached to it, then decide whether the offer makes sense for your needs without relying on an assumed discount or promotion.
Make your Black Friday choice
The best Nest thermostat choice depends on what you want to control and what your system supports. Choose the Snow model for app-programmed scheduling and remote adjustment, consider the 3rd gen Learning Thermostat for a schedule that learns your preferences, or look at the 4th gen bundle for its included sensor and room-temperature scheduling. Check wiring and compatibility carefully, and verify the exact model and bundle before completing a Black Friday purchase. Compare the offer shown for that specific listing with the features you will use; do not assume every Nest thermostat has the same package or qualifies for the same deal.
