Google Nest thermostat showing offline in app
A thermostat goes offline when it loses WiFi connection or can't communicate with Google's servers. Reconnecting it to WiFi and checking your WiFi settings fixes this in most cases.
When your Nest thermostat shows offline, it's disconnected from your WiFi network or can't reach Google's cloud servers. We'll reconnect the thermostat to your network, confirm your WiFi is working, and make sure the connection is stable.

Skip, I just want a technicianCommon mistakes to avoid
- Reconnecting the thermostat but not checking that the router settings support the band the Nest needs
- Not waiting long enough for the reconnection to complete — it can take up to 1 minute for the device to fully connect and appear online
- Changing the WiFi password without updating the thermostat — the device can't reconnect automatically
Signs you need professional help
- If the thermostat won't connect to WiFi after reconnecting and the signal is strong, or if your HVAC system isn't working at all, get in touch with a technician. The WiFi module or HVAC wiring may need service.
