I just spent the most frustrating 3 hours! See the photos. I followed the instructions carefully, think I wired everything as it should be. But at the end, “WYZE” did not appear on the thermostat! I double-checked all the wiring. Finally had to remove it and reinstall the old thermostat because it was getting cold in the house (I live in Wisconsin). Does anyone see anything wrong? I think I’m gonna need to return this and get another, maybe the unit is bad.
