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

Most smart thermostats fail to connect because of weak Wi‑Fi, an incorrect network/password, 5 GHz network incompatibility, or low thermostat power. Try moving closer to the router, confirm the SSID/password, and connect to a 2.4 GHz network. If it reboots or shows power issues, a C‑wire or compatible power add‑on may be needed. Our Dayton technicians can assess wiring, confirm compatibility, and handle setup, calibration, and testing.

Quick checks:

• Power cycle the thermostat and router.
• Ensure HVAC breakers are on.
• Avoid guest networks when pairing.
