Your Sera thermostat comes with dedicated support from the people who built it. Your home is precisely maintained — and so is your ownership experience.
Troubleshooting
Thermostat is unresponsive
Check your HVAC circuit breaker. If power is confirmed, remove the Sera unit from its base for 10 seconds, then reattach. Still unresponsive? Schedule a call.
Wi-Fi connection lost
Open the Sera app → Settings → Wi-Fi and re-enter your credentials. Sera supports both 2.4 GHz and 5 GHz. Restart your router if needed.
Incorrect temperature reading
Ensure the thermostat is out of direct sunlight and away from vents. Adjust calibration under Settings → Sensor Offset in the app.
Heating or cooling won't start
Confirm your HVAC system is powered and the filter is clean. Run a system test under Settings → Diagnostics in the Sera app.
App won't connect to the thermostat
Enable Bluetooth during initial setup. Ongoing: both your phone and Sera must share the same Wi-Fi network. Re-link via App Settings → Devices.
