Wyze Thermostat on 2 wire system

I’m not sure about the adapter. Seems it wouldn’t help me with my 2-wire furnace, but I don’t remember why.

What I did was power my Wyze thermostat with two wires from a simple doorbell transformer, and then I connected the two wires from my furnace to the thermostat. Easy peasy, and it’s been working for a couple of years now without issue – even with countless power outages.

It automatically comes back online after a power outage, assuming your wifi and internet also are online. In addition, it will run whatever schedule you have set if the internet goes out, but the power stays on.
