Hi community. My house is a month away from finishing and I would like to put in two Wyze Thermostats. I spoke with NEST, showed them my wire configs (as attached below) and they verified it would work. When I did the Wyze Thermostat compatibility checker, it did not show a selection or port for my U1 wire that I currently have in my dumb thermostat that comes with the house.
*all of the other wires I know are standard and look ok.
Anyone have any idea what I would connect the U1 wire with?
