What Is The Latest Generation Of Nest Thermostat? | Now

If you are shopping for a Nest thermostat today, the model list can feel confusing. There is the Nest Learning Thermostat in several generations, the simpler Nest Thermostat, and older devices that are still on many walls. Knowing which one counts as the latest generation helps you avoid buying hardware that is close to retirement or missing newer features you may want.

This article breaks down which Nest thermostat generation is the newest, how it fits into the rest of the lineup, and what that means for upgrades. You will also see how to check your own thermostat’s generation, plus a few buying checks so you can match the right Nest device to your home.

Latest Generation Of Nest Thermostat Models

The newest Nest thermostat generation is the Nest Learning Thermostat 4th gen. Google launched it in 2024 as the successor to the long running 3rd gen Learning Thermostat and has been rolling out steady software updates through 2025. It sits above the entry level Nest Thermostat from 2020 and the mid tier Nest Thermostat E.

On Google’s own pages, the Learning Thermostat 4th gen is now listed alongside the 3rd gen, Thermostat E, and Nest Thermostat, with its own section in official release notes and in the Google blog coverage of its new Farsight faces. Those two signals show that this model is the current generational flagship instead of a minor variant.

At a high level, the 4th gen Learning Thermostat brings three main changes compared with earlier Nest models:

• Refined hardware design The 4th gen keeps the familiar round body but adds new finishes and a brighter, more reflective screen that can show richer faces when you walk by.
• New Farsight faces Seasonal and minimal faces add clearer icons and energy views when the thermostat lights up from across the room.
• Updated compatibility and software Wider compatibility with modern HVAC wiring, improved Google Home app integration, and an active update track that older generations will not share forever.

The plain Nest Thermostat (the 2020 square edged model) is still a current product, but it does not have a numbered generation. When people ask about the latest Nest thermostat generation, they almost always mean the Learning Thermostat family, where 4th gen is now the top step.

Current Nest Thermostat Lineup At A Glance

Before you pick a model, it helps to see where each Nest thermostat sits in the range. The table below summarises the main Nest thermostat lines and their current status.

Model	Generation And Release	Status Today
Nest Learning Thermostat 4th gen	4th generation, released 2024	Newest flagship, active software updates
Nest Learning Thermostat 3rd gen	3rd generation, released 2015	Still on an active update track, older design and feature set
Nest Thermostat	Unnumbered model, released 2020	Current budget option with Google Home app focus
Nest Thermostat E	Single generation, released 2017	Still in the field, no longer widely sold new
Nest Learning Thermostat 1st and 2nd gen	Released 2011–2014	Retiring from smart features, only basic local control after 2025

Google has already announced that the earliest Learning Thermostat generations will lose app connectivity and updates from late 2025 while they continue to work as simple wall thermostats. The 3rd gen, Thermostat E, 2020 Nest Thermostat, and 4th gen Learning Thermostat remain on an active update schedule through the Nest thermostat software update history and related help articles.

The practical takeaway is simple: if you want the latest generation Nest thermostat, you are looking at the Learning Thermostat 4th gen. If you just want a cheaper way into the Nest lineup, the 2020 Nest Thermostat remains a current option, and many homes with 3rd gen or Thermostat E units can keep them in service without rushing to replace them.

How To Tell Which Nest Thermostat Generation You Have

Many Nest owners already have a thermostat on the wall and only need to know whether it is an older generation. Nest model names are similar, so a quick check saves time before you plan an upgrade.

Check The Device Itself

• Look at the shape and ring Learning Thermostats are round with a rotating metal ring, while the 2020 Nest Thermostat has a flat touch strip on the side and a more compact face.
• Check the display style The Thermostat E has a frosted, soft looking screen, the 3rd gen has a clear bright screen, and the 4th gen combines a bright screen with new animated faces in the Farsight view.
• Open the access door if present Some early Nest models and some regional versions include subtle markings near the wiring terminals that list a generation number or model ID.

Use The App To Read The Model Name

The Google Home and Nest apps both list the thermostat model once the device is set up. That label is a simple way to confirm what you own.

• Open the app Launch the Google Home or Nest app on your phone and sign in with the account that controls your thermostat.
• Select your thermostat Tap the thermostat tile from the home screen to open its detail page.
• Open device settings Go into the settings menu and look for a line labelled model or technical information, where you will see names such as “Nest Learning Thermostat 3rd gen” or “Nest Thermostat”.

Match Model Details With Google’s Help Pages

Once you know the model name, you can match it with the descriptions and photos on Google’s help site. The Nest thermostat software update history page lists Learning Thermostat 4th gen separately from earlier generations, along with release dates and version numbers. Cross checking your model name against those entries confirms whether you own the latest generation.

Should You Upgrade To The Nest Learning Thermostat 4th Gen?

Knowing that the 4th gen Learning Thermostat is the latest Nest thermostat generation is only half the story. The next question is whether an upgrade makes sense for your home and budget.

When An Upgrade Makes Strong Sense

• You own a 1st or 2nd gen Learning Thermostat These early models lose app based controls and new features from late 2025, so a newer thermostat keeps remote control and active security patches.
• You want the best Nest experience long term The 4th gen Learning Thermostat sits at the top of Google’s current range, with an active feature plan, rich Farsight faces, and deep Google Home integration.
• Your current thermostat struggles with your HVAC system If your present Nest often reports power issues, drops Wi Fi, or cannot control newer multi stage or heat pump systems, the 4th gen model’s updated compatibility list may resolve those pain points.

When You Can Wait

• You own a 3rd gen Learning Thermostat or Thermostat E These models continue to receive updates and work with Google Home, so you can hold off until you see a feature you truly want from the 4th gen.
• You installed the 2020 Nest Thermostat recently The 2020 model remains a live product with ongoing updates, and it already offers remote control, scheduling, and Matter smart home standards.
• Your energy use is already under control If your home is well insulated, your schedule is stable, and bills are in a good place, the upgrade gains may be modest compared with other energy projects.

Smart thermostat savings always depend on how your home is used, but research from the U.S. Department of Energy on programmable thermostat settings shows that even simple schedule changes can lower heating and cooling costs by around ten percent across a year. Smart thermostats such as the Nest Learning Thermostat automate that behaviour and can make those savings easier to sustain.

Latest Generation Of Nest Thermostat Models And Buying Checks

Once you have decided to buy the latest generation Nest thermostat, a short checklist helps avoid unpleasant surprises on installation day. The Learning Thermostat 4th gen is designed for a wide range of systems, yet there are still a few details to verify.

Confirm HVAC Compatibility

• Identify your system type Write down whether you have central heating only, heating and cooling, a heat pump, or another setup such as radiant floor heat.
• Use Google’s online compatibility checker Google maintains a simple questionnaire that lets you enter your HVAC wiring and shows whether your system works with the latest Nest thermostats.
• Check for accessories and extras If you have humidifiers, dehumidifiers, or a separate fan controller wired into the old thermostat, confirm that the new Learning Thermostat can handle those connections.

Look Inside Your Existing Thermostat

A quick look at the wiring behind your present thermostat gives a clear picture of what the Nest Learning Thermostat 4th gen will need.

• Turn off power to the HVAC system Switch off the breaker or dedicated switch for your heating and cooling equipment before removing the thermostat faceplate.
• Photograph the wiring Take a clear photo of the wire labels and where each conductor lands. This makes the Nest install steps easier and lets you share details with an installer if you need help.
• Look for a C wire or spare conductor While the latest Nest Learning Thermostat often works without a dedicated common wire, having one available improves stability on some systems.

Plan Where The Thermostat Will Sit

Placement matters for comfort and for the Farsight faces that distinguish the 4th gen Learning Thermostat.

• Check the viewing angles The screen is designed to be readable from across the room, so pick a spot where you are likely to see it from common living areas.
• Avoid heat or cold spots Do not mount the thermostat over supply vents, near ovens, or in direct sun, as that can skew its temperature reading.
• Consider a stand if wall wiring is awkward In some regions, the Learning Thermostat can sit on a stand on a shelf, with the Heat Link or similar module wired elsewhere.

Ways To Get The Most From Any Nest Thermostat

Once you have a Nest thermostat in place, fine tuning a few settings helps you get better comfort and lower bills from the hardware you already own.

Use Scheduling And Presence Features

• Set a realistic schedule Create a weekday and weekend schedule that reflects when people are home, asleep, or away, so the thermostat can trim heating and cooling when rooms sit empty.
• Enable home and away automation Allow the thermostat and the Google Home app to use phone location and motion sensing to catch unexpected absences and adjust temperatures automatically.
• Watch the energy history Check the energy reports inside the app each month to see when heating or cooling peaks, then adjust set points or habits where it makes sense.

Pair With Simple Home Changes

Smart thermostats work best when the rest of the house works in your favour. Small changes in how you run your home can boost the impact of a Nest thermostat.

• Seal obvious drafts Use basic weather stripping or draft excluders around doors and windows so the thermostat does not have to compensate for large air leaks.
• Use curtains and blinds Keep heat inside on cold nights and block strong sun on hot days to steady indoor temperatures.
• Service your HVAC equipment on schedule A clean filter, tuned burner, and checked refrigerant level help your system respond accurately to thermostat commands.

If you want more detailed advice on temperature targets and schedules, the U.S. Department of Energy’s Energy Saver guidance on programmable thermostats lays out simple temperature bands that still work well with modern smart thermostats. Nest devices can follow those bands automatically with the right schedule and presence settings.

Once you understand that the Nest Learning Thermostat 4th gen is the latest Nest thermostat generation, the rest of the decision turns into matching that model against your own home. Confirm your HVAC compatibility, look at how you use each room across the day, and then decide whether an upgrade now will save enough time, comfort, and energy to be worth the spend.
