Continuing the discussion from Wyze Thermostat Clicking and no screen:
Hey my thermo stat is just clicking
The blue wire at the furnace isn’t connected to anything, Remove the C adapter and connect all the wires back where they were, and make sure the blue wire is on the C terminal. Do you have a picture of the furnace board before you changed anything?
Make sure to tell wyze that your “old thermostat” has the following wires during setup: Rc, Y1, G, W1, C
