2026 verdict
Generation gap, but not a clear upgrade: the Sensi Touch smart thermostat keeps Apple HomeKit support that its successor dropped, and it matches the Sensi Touch 2 smart thermostat on screen size, humidity sensing and warranty.

Choose the Sensi Touch smart thermostat for an Apple Home household, and the Sensi Touch 2 smart thermostat when 5 GHz Wi-Fi and room sensors matter more than HomeKit.

What the differences mean
Apple HomeKit
The Sensi Touch smart thermostat supports Apple HomeKit. The Sensi Touch 2 smart thermostat does not, so an iPhone household that lives in the Home app loses that route by choosing the newer model.
Extra room sensors
The Sensi Touch 2 smart thermostat supports external temperature sensors for balancing rooms, while the Sensi Touch smart thermostat does not, so it only reads the wall it is mounted on.
Wi-Fi bands
The Sensi Touch 2 smart thermostat joins 2.4 GHz and 5 GHz networks. The Sensi Touch smart thermostat is 2.4 GHz only, and owners of the older model name that as the step that gave them trouble on some routers.
Body size
The Sensi Touch 2 smart thermostat is slimmer at 142 x 82 x 20 mm, while the Sensi Touch smart thermostat measures 137 x 81 x 26 mm. Both have a 4.3-inch color touchscreen and come in several color options.
Which one to buy if
- your home runs on Apple Home
The Sensi Touch smart thermostat supports Apple HomeKit and the Sensi Touch 2 smart thermostat does not.
- you want to add sensors to even out room temperatures
Only the Sensi Touch 2 smart thermostat supports external temperature sensors.
- your router merges 2.4 and 5 GHz under one network name
The Sensi Touch 2 smart thermostat handles both bands, avoiding the pairing friction of a 2.4 GHz only thermostat.
- you want a slimmer body on the wall
It is 20 mm deep against 26 mm on the Sensi Touch smart thermostat.

What owners say
Owners of both Sensi Touch models describe the same easy installation: the app maps the existing wires to the new terminals, so first-time installers finish without an electrician, and both groups praise the clear color touchscreen. Sensi Touch smart thermostat owners add that no batteries are needed, that humidity monitoring is handy and that voice control works across Alexa, Google Home and HomeKit, while the main complaint is a difficult first Wi-Fi pairing on some home networks. Sensi Touch 2 smart thermostat owners single out the glass design that looks premium beside older thermostats and the ability to balance rooms with add-on sensors, while a minority report Wi-Fi dropping after a few months, trouble pairing a sensor and missing advanced diagnostics.
Upgrading from the Sensi Touch smart thermostat?
Moving from the Sensi Touch smart thermostat to the Sensi Touch 2 smart thermostat buys 5 GHz Wi-Fi, support for external temperature sensors and a slimmer body, and it costs you Apple HomeKit support. The screen size, humidity sensing, warranty and Google Home, Alexa, SmartThings and Home Assistant support stay the same. If your Sensi Touch smart thermostat already keeps its Wi-Fi connection and you use Apple Home, there is no reason to move. If you want room sensors, the newer model is the one that offers them.
