Why Is My Smart Thermostat Not Connecting to Wi-Fi?
Most smart thermostats fail to connect because they use 2.4 GHz, your router is on 5 GHz, the signal is weak, or the password is wrong. Router settings like MAC filtering, hidden SSID, or disabled DHCP can also block pairing.
Quick checks:
- Reboot the thermostat and router.
- Join the 2.4 GHz SSID and move closer.
- Re-enter the Wi‑Fi password.
- Disable MAC filtering/AP isolation; enable DHCP.
- Update router and thermostat firmware, then retry setup.
We also test controls and remote operation during tune-ups.
