Wyze Thermostat - Battery Powered

[bd0]

Hey @sungrd1

I have a radiator system with only two wires and just bought a 24V transformer and hooked it up using this method - hope it works for you:

Thermostat with external transformer

I’ve had to get one as well, but hasn’t came in yet. I have a radiant floor heat system that just has two wires running from the thermostat to the switch that turns on the water pumps.
