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:

1. Open the Sensi app and select the thermostat you want to view from the dashboard screen.
2. (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
3. Select About thermostat.
4. Thermostat model: Make sure that the thermostat is a 1F87U-42WF or a 1F95U-42WF. These are the only two models receiving this feature.
5. 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.
