Every time the power goes out I have to manually go to the thermostat and reconnect the WiFi. What's odd is i don't have to input the wifi password. It connects right a way to the router once you click on the wifi name with no problem but I have to do this every time. It's in a hallway and connected to an access point which is only 10ft away in my bedroom. I have 5 Nest cameras and doorbell that connect right away once power is restored and 2 of them are on the access point so the wifi isn't the issue.
