The Sensi Touch smart thermostat is the better overall pick, thanks to a higher owner rating and an included trim plate option. The Sensi Touch 2 smart thermostat counters with dual-band Wi-Fi and external temperature sensor support.

Wi-Fi and sensors. The Sensi Touch 2 smart thermostat adds dual-band 2.4GHz/5GHz Wi-Fi and external temperature sensor support, while the Sensi Touch smart thermostat is 2.4GHz-only. Both share the same 4.3-inch color touchscreen, humidity sensing and 3-year warranty.

The Sensi Touch 2 smart thermostat supports both dual-band 2.4GHz/5GHz Wi-Fi and external temperature sensors, which can help on 5GHz-heavy networks and for balancing rooms. The Sensi Touch smart thermostat is limited to 2.4GHz and its built-in sensor.

No, neither the Sensi Touch smart thermostat nor the Sensi Touch 2 smart thermostat supports Apple HomeKit. Both work with Google Home, Alexa, SmartThings and Home Assistant, with a color touchscreen and voice control.

Buyers who want dual-band 2.4GHz/5GHz Wi-Fi and the option to add external temperature sensors for multi-room balancing, and are fine going without a bundled trim plate.

Buyers who want the higher-rated Sensi touchscreen with an available trim plate and do not need 5GHz Wi-Fi or external sensor support, since the two are otherwise nearly identical in features and warranty.
