Important Note: Your Sensi thermostat will control your heating and cooling system even if the Wi-Fi connection has been lost. You can still make temperature/system mode changes from the thermostat on the wall. If you are running a schedule when connection is lost, your Sensi thermostat will continue to run the schedule. However, additional features such as modifying advanced settings, switching between schedules, and automatic software updates will not be available until the Wi-Fi connection is restored.
