Looking for sensi smart thermostat alternatives? You might want to explore other options if your needs differ from the Sensi ST55.

However, you may need different features. Some users prefer a touchscreen display or Apple HomeKit support. Others require a C-wire for more stable power.

How each alternative compares
Ecobee Smart Thermostat Essential
The Ecobee Smart Thermostat Essential shares the Sensi ST55’s Alexa compatibility and Energy Star certification. It also supports flexible programming for daily schedules.

It provides more visual feedback than the Sensi.
Sensi Lite Smart Wi-Fi Thermostat
The Sensi Lite Smart Wi-Fi Thermostat shares the ST55’s Alexa compatibility and Energy Star certification. It uses Wi-Fi for connectivity. The key difference is the lack of a display.
