Why Is My Smart Thermostat Not Connecting to Wi-Fi?

Your smart thermostat usually won’t connect because of a power issue (often no C‑wire) or a home network problem. Check that the thermostat has steady power and confirm your Wi‑Fi name and password. Restart the router and the thermostat. Move the router closer if the signal is weak, then retry the app setup. If it still won’t join, we can diagnose the control and wiring. Our diagnostic visit is $179 and is waived with repair. We serve Garden City, NY and nearby.
