How do I add the circulating fan feature to my existing Sensi thermostat?
The circulating fan feature was released in an over-the-air firmware update to all Sensi Smart Thermostats compatible with HomeKit and Sensi Touch models (ST-55, 1F87U-42WF, ST-75, 1F95U-42WF). You will need the latest firmware to access circulating fan.
Check your firmware version:
- Open the Sensi app and select the thermostat you want to view from the dashboard screen.
- (iOS users) Navigate to Settings by selecting the gear icon at the top right of the screen. (Android users) Navigate to Settings by selecting the three-dot menu button at the top right of the screen
- Select About thermostat.
- Thermostat model: Make sure that the thermostat is a 1F87U-42WF or a 1F95U-42WF. These are the only two models receiving this feature.
- Thermostat Firmware Version: Check your thermostat firmware version. If it is not version 500 or version 600 (depending on your model) or later, then allow 24 hours after initially connecting to Wi-Fi to receive this update.
- ST-55/1F87U-42WF – firmware version 6004850703 or later
- ST-75/1F95U-42WF – firmware version 6004970705 or later
