If your Wi-Fi connection is lost, the thermostat will continue to follow scheduled set points. You can still make changes manually, using the buttons on the thermostat itself. However, you will not be able to make changes remotely from your smartphone or tablet. When the connection is re-established, you will be able to make changes to the schedule and temperature through the Mysa app once again.
