It ships with a remote temperature sensor, notices when people are home through its proximity and occupancy sensing, learns a schedule on its own and adds Matter, temperature alerts and a system health monitor. The Sensi Touch smart thermostat answers with a larger 4.3 inch color touchscreen, native Home Assistant support, a three-year warranty against two and a lower price, but it has no occupancy sensing and cannot use a remote sensor at all. Both work with Google Home, Alexa, Apple Home and SmartThings. Pick the Google Nest Learning Thermostat (4th gen) for a hands-off house with uneven rooms, and the Sensi Touch smart thermostat for a simple, touch-controlled upgrade on a budget.

What the differences mean

Room sensors and occupancy

The Google Nest Learning Thermostat (4th gen) comes with a remote temperature sensor and detects presence, so it can favour the room you are in and back off when nobody is home. The Sensi Touch smart thermostat reads the temperature only where it is mounted and has no occupancy sensing, so a cold bedroom stays cold.

Screen and controls

The Sensi Touch smart thermostat has a 4.3 inch color touchscreen you tap. The Google Nest Learning Thermostat (4th gen) has a smaller 2.7 inch color display that is turned with its dial rather than touched, and it shows the weather, which the Sensi does not.

Smart home platforms

Both work with Google Home, Alexa, Apple Home and SmartThings. The Nest adds Matter, while the Sensi Touch smart thermostat has full Home Assistant support where the Nest is only partial, which matters if Home Assistant runs your automations.

Wi-Fi

The Google Nest Learning Thermostat (4th gen) joins 2.4 or 5 GHz Wi-Fi and has Bluetooth. The Sensi Touch smart thermostat is 2.4 GHz only, which is where its owners' pairing trouble comes from on routers that merge both bands under one name.

Warranty

Sensi covers the Touch for three years and Google covers the Nest for two, a small but real point in favour of the cheaper thermostat.

What owners say

Owners of both thermostats talk about easy installs and app control they actually use, pre-heating or cooling the house from the phone. From there the stories split. Google Nest Learning Thermostat (4th gen) owners single out the learning itself, a thermostat that eases off when the house empties and kicks in as they arrive, the bright animated display and the bundled sensor that evens out a bedroom overnight; their complaints are about power without a C-wire where an older Nest ran fine, and control moving to the Google Home app only. Sensi Touch smart thermostat owners praise the app that walks them through the old wiring, the clear touchscreen and a thermostat that simply keeps working, while their recurring complaint is getting it onto a Wi-Fi network in the first place.
