Thermostat displays E11 and cannot complete initial setup or connect to Wyze cloud services.

Safety first: No electrical work is required for this error.

• Check Wyze service status: Visit Wyze’s official status page or community forums to see if there is a known cloud outage.
• Verify account credentials: In the Wyze app, log out and log back in to confirm your username and password are correct.
• Check network firewall: Ensure your router or firewall is not blocking outbound connections for IoT devices. Disable VPNs or advanced filtering temporarily to test.
• Remove and re-add device: In the Wyze app, remove the thermostat from your account, then perform a factory reset on the thermostat (follow Wyze instructions) and re-add it as a new device.
• Try alternate network: Temporarily connect the thermostat to a different 2.4 GHz network (such as a mobile hotspot) to determine if the issue is with your home network.
