It has proximity, occupancy and ambient light sensors that drive an eco and away mode, sends temperature alerts, shows the weather on a 2.4 inch colour display, joins 2.4 or 5 GHz Wi-Fi with Bluetooth, works with Apple Home and comes in four colours.

What the differences mean

Display and controls

The Google Nest Thermostat has a 2.4 inch colour screen behind a mirrored lens that also shows the weather, driven by a touch strip on the side. The Sensi Smart thermostat uses a wider 5 inch monochrome LED display with physical controls. Neither is a touchscreen.

Presence sensing

The Google Nest Thermostat has proximity, occupancy and ambient light sensors, so it can wake its display, notice an empty house and correct for sun on the wall. The Sensi Smart thermostat lists none of them and works from its schedule and your settings.

Home Assistant and warranty

The Sensi Smart thermostat is listed with full Home Assistant support and a three year warranty, while the Google Nest Thermostat is only partially supported and covered for one year.

Wi-Fi and alerts

The Google Nest Thermostat sends temperature alerts and connects on 2.4 or 5 GHz Wi-Fi with Bluetooth. The Sensi Smart thermostat has no temperature alerts and is 2.4 GHz only.

Apple Home

Only the Google Nest Thermostat works with Apple Home; the Sensi Smart thermostat does not.

What owners say

Google Nest Thermostat owners lead with value: replacing an old dial or never-programmed thermostat, they report lower heating bills, sometimes a utility rebate that made it nearly free, and they like controlling it from the phone to pre-heat or pre-cool before getting home. The eco and away mode, which combines phone location with the motion sensor, is credited with cutting wasted heating, and the install takes around half an hour with the app guiding it. Their caveats are practical: a C-wire or Nest's adapter is required, control lives only in the Google Home app, and the eco mode can switch on too eagerly. Sensi Smart thermostat owners describe a guided self-install, physical buttons, easy schedules and fan circulation settings, but note the app's US and Canadian address requirement and occasional Wi-Fi drops.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
