Thermostat Shows Offline or Cannot Connect to App

Symptoms

• App shows device as "Offline" or "Unreachable"
• Wi-Fi icon on the thermostat display is absent or showing an error
• App changes do not take effect on the thermostat
• Thermostat operates locally but remote control does not work

Likely Causes

1. Wi-Fi router was restarted or changed since the thermostat was set up
2. The T1 is connected to a 5 GHz band; it only supports 2.4 GHz
3. The router is out of range or signal is weak at the thermostat location
4. The Monverta cloud service is temporarily unavailable
5. The thermostat firmware needs updating

Step-by-step Fix

1. On the thermostat, go to Settings > Wi-Fi. Check whether a network name is shown. If it reads "Not connected," the T1 has lost its Wi-Fi credentials.
2. Restart your router and wait 2 minutes. Check whether the thermostat reconnects automatically — many disconnections are caused by a temporary router restart.
3. Confirm your router broadcasts a 2.4 GHz network. If you have a combined 2.4/5 GHz network, split the bands in your router admin panel and connect the T1 to the 2.4 GHz band specifically.
4. In the app, go to Settings > Device > Reconnect and follow the steps to re-enter your Wi-Fi credentials.
5. Check status.monverta.com to confirm there is no active service outage.
6. If the device has a pending firmware update, the T1 will prompt you on screen — apply it and retest.
