Hi folks,
Thanks for reaching out. I'm sorry for the trouble this may have caused you. Sometimes a range issue or wireless interference can cause your sensor to disconnect from your thermostat. In these cases, your thermostat will automatically default to using its own temperature sensors. If your sensor disconnects, you may experience the following:
- You may not notice that your sensor is offline right away. Instead, you might only sense that you’re uncomfortable in the room where the sensor is placed.
- If your sensor has been disconnected from your thermostat for over 24 hours, you’ll get a notification on your phone. You will also find that the sensor is offline on the Nest app home screen, and you won’t be able to manually switch to it with the app or thermostat.
- If you check the sensor list, you’ll also find that your sensor will be grayed out and you won’t be able to select it or change options.
Try the troubleshooting steps here:
- Try moving your sensor a bit closer to your thermostat. Sometimes it may pass the connection test during setup, but will struggle to stay connected if it’s just a bit too far away.
- Check for objects such as mirrors and refrigerators between the sensor and your thermostat. These items could block the connection. For more help, read Troubleshooting wireless interference.
- Check the battery charge. The Google Home app or Nest app will send you a notification before the battery is fully drained, so you should have plenty of time to replace it.
- If the battery still has a charge, try removing it for 10 minutes. This lets power drain completely from the sensor and forces it to reset. Then put the battery back in and check if the sensor has reconnected in the Nest app.
Best,
Jenelyn
