Before you buy

What do you need to make it work?

No hub for the device alone

Choose a platform above for its connection. A hub can be optional for the device itself and required for a platform or automation.

Equipment that adds features

Check which features need it

Matter controller

Not needed for the Google Home app. Google says controlling the thermostat from another maker's platform or app may need that maker's own Matter hub.[13][28][44][74]

One device can provide more than one role. These are setup requirements, not a shopping list of separate purchases.

What could you do with this?

Put its functions to use.

Research, not hands-on testing

Start with a documented control or event. The selected connection shows what is confirmed for that platform.

Matter device-type support is based on the platform’s list for this kind of device; this exact model is not named.

Setup and sources

Apple Home

Matter only — needs an Apple home hub (HomePod or Apple TV) for remote control, and Apple Home gets basic temperature/mode control, not Nest's learning features. First Nest LEARNING Thermostat to work with Apple Home (the 2020 budget Nest Thermostat got there first, via its April 2023 Matter update).[6][28][44][61][62][77]

Google Home

Deepest integration + auto-learning[7][27][28][43][44][63][64][65][73][74][75]

Alexa

Alexa connects via Matter (no Nest skill setup for this model). For Matter thermostats Amazon lists setting the temperature and asking for the current temperature, with no Nest schedules or learning features, and you need a Matter-capable Echo as the controller.[5][28][37][44][60][62][76]

SmartThings

Matter only — you need a SmartThings hub (standalone, or built into recent Samsung TVs/appliances) as the Matter controller, and Samsung documents Matter-thermostat support generically rather than naming this model.[9][38]

Home Assistant

Via Matter you get standard local climate control; Home Assistant's official Google Nest (SDM) cloud integration is the documented alternative — it covers all Nest thermostat models but requires Google's one-time $5 Device Access fee.[8][39][40][53][66][78]

Plans and ongoing costs[3][24][27][43][73]

✓ Works without a subscription: Yes.

Vendor account required: Yes — you must create a vendor account to use it. (established from the maker's own statement that this model can only be set up in its app, which itself requires an account)[15][32][48]

Maintenance and offline use[4]

The catch

Learning features are fullest in Google's app; elsewhere it works as a Matter thermostat.

Where Google Nest's own pages disagree

how often this thermostat needs a C wire or the Nest Power Connector

On how often this thermostat needs a C wire or the Nest Power Connector, this page shows both, with the help article's system list first, in maintenance.notes. Google's C wire help article says heating-only, cooling-only, zone-controlled and heat pump systems need a C wire or the Nest Power Connector, while its specification page says one is needed in under 1% of homes, so this page gives the help article's list first.

Who it's for

Set-and-forget households: it learns your schedule so you don't program one.
