Has anyone else experienced this and is there a solution. Just bought a new home with a Nest and the following wiring configuration W, Y, G, R, C (a blue wire), OB. It is connected with my wifi and has the Matter App installed (no idea what that does). Recently, in the evenings, the device has "shut down" showing "No Power", I check the device, and the wiring set-up shows as greyed out. I check to ensure the HVAC system is still on, flip the circuit breakers, check the condensation pan to ensure the limit switch is not tripped, go back restart Nest and nothing. Restart Nest and nothing, Factory reset and nothing, Pull the Nest, all wires still connected, use a multimeter to check the wires...nothing, but was working fine during the day.
All set to call a "Nest Pro" in the am to check wiring, get up and everything is fine, power good, wiring set-up is illuminated.
I have checked to ensure there is no routine set-up from the previous owner, checked schedule settings, nothing obvious to me that will explain why it has shut down with "No Power" in the evening and then starts back up during the day.
