You’re in the wrong section of the forum for this, but you would need a C-adapter transformer like this, connected to Rc and C. Then take the existing wires on your thermostat and connect the red one to Rh and the white one to W1. Tell the wyze that you have those 4 wires during setup. (Rc, C, W1, Rh)
You will be losing one of the nice features of your current thermostat - it works even when there’s no power, so if you wanted to retain this functionality, you could leave the current thermostat attached, and just turn it all the way down. Then run 2 additional wires from the current thermostat to the proper terminals on the wyze, leaving the thermostats hooked up in parallel, so that if the power goes out, you can just raise the temp on the old thermostat to power on the furnace.
I’m assuming you have one of these models.
