Answers to Common Questions
View All FAQsWhy Is My Smart Thermostat Not Connecting to Wi-Fi?
Your smart thermostat usually won’t connect to Wi‑Fi because of weak signal, incorrect Wi‑Fi credentials, or a router/internet outage. Our certified technicians install, optimize, and set up the app so your system connects correctly. We help Las Vegas and Henderson homeowners with Nuve and other popular brands.
Quick checks:
- Verify the Wi‑Fi name and password.
- Check signal strength at the thermostat.
- Power‑cycle the router and thermostat.
- Confirm the thermostat is in pairing/setup mode.
- Retry the app setup once internet is restored.
