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

Your smart thermostat usually won’t join Wi‑Fi because of a weak signal, incorrect network credentials, or a power issue at the thermostat. Try these quick checks:

• Confirm your home Wi‑Fi works on a phone near the thermostat.
• Re-enter the correct network name and password.
• Power-cycle the thermostat and router.
• Improve signal by moving the router or reducing interference.
• Ensure the thermostat has steady power. We include thermostat testing and calibration during HVAC tune-ups and can repair or replace as needed. Protection Plan members receive a 10% HVAC service discount in Milwaukee.
