We have two nest in our home. The downstairs unit keeps falling offline. It sends a message: “Thermostat doesn’t have enough power for Wi-Fi.” However, when switching the units, down to up, the upstairs unit worked just fine in the downstairs location. So I know that there is enough power at the location downstairs. Restarted the system and hooked it back to the Wi-Fi where it stayed connected for about 3-4 hours. Is this a dead unit or is there some other form of trouble shooting?
