Troubleshooting Vivint Thermostat Offline Issues
Check Your Wi-Fi Connection
Start by ensuring your thermostat is connected to a stable Wi-Fi network. Check the Wi-Fi signal strength in the area where your thermostat is installed. If the signal is weak, consider moving your router or using a Wi-Fi extender to boost the signal.
