Hi - I had my hopes up that my thermostat preorder would work fine with my system but the app says it’s incompatible. After seeing some suggestions here for others with three wires (different colors than mine) I’m hoping there’s a workaround.
I have Red, Yellow, and Green wires as shown in this lousy picture I took a few days ago:
My current thermostat is a battery-powered Honeywell. I saw some people were advised to use a 24v transformer but I don’t have a power outlet near my thermostat.
Any advice? Is the magic man, @speadie out there?
