Method 1: Make Sure the Thermostat is Compatible
When purchasing a Nest Sensor, you must check that the sensor is compatible with your actual thermostat. However, the company made these types of sensors to only work with the Nest Learning Thermostat 3rd generation, and the E model is incompatible with the Nest Thermostat mirror version. If you are currently trying to use Nest sensors with another brand or device that isn’t compatible, the sensors won’t work at all.
Method 2: Reboot Your Sensor
Rebooting the thermostat refreshes the device and helps you resolve the issue preventing the connections between the two devices. If your thermostat is compatible with your sensor and you are still facing the sensor not working issue, try to reboot your Nest sensor. To reboot your sensor, follow these steps:
- Remove the battery of your sensor.
- Wait for at least 60-90 seconds.
- Now put the battery back in and power on the sensor.
These should reset the sensor and allow it to start taking more accurate readings. If you continue to experience temperature errors, you can also try calibrating your Nest thermostat to ensure that it’s measuring the correct temperature.
Method 3: Reduce the Distance Between the Sensor and the Thermostat
If your Nest Temperature Sensor has stopped working, it may be due to the distance between the sensor and the thermostat. To fix this issue, reduce the distance between the sensor and thermostat by moving them closer together.
Make sure that the sensor has a clear line of sight to the thermostat and avoid placing any obstructions between them.
It is also recommended to reduce the number of walls between the two, as walls can interfere with the connection. Finally, ensure that your thermostat is in the Wi-Fi range of your router.
Method 4: Make Sure Phone Bluetooth is Enabled
The Nest sensor and the thermostat are linked with the Nest app. They connect and share data with the help of Bluetooth communication protocol, so your mobile’s Bluetooth needs to be enabled to let these two devices exchange information without any issue. To turn on Bluetooth on an Android device, follow these steps:
- Swipe down from the top of the screen or go to the settings.
- Tap on the Bluetooth option and turn on the toggle.
- Search your device and tap on connect.
To turn on Bluetooth on an iPhone device, follow these steps:
- Open the Settings app on your iPhone device.
- Go to the Bluetooth section.
- Tap on the toggle to switch on the Bluetooth.
- Search the device and tap on connect.
Method 5: Replace the Battery
The Nest Temperature Sensor comes with a CR2 lithium battery that can last up to 2 years. When the battery level is down, the device’s overall performance will be low, and the device’s connection will not work properly.
A notification will be sent to your mobile, and you will be alerted in the Nest app when the battery sensor is reduced. So, if the battery is low, purchase a new battery of the same size and make sure to choose a high-quality model and replace it with the old one. To do this:
- Take out the old battery and replace it with a new one of the same size.
- Ensure the new battery is securely placed in the sensor and the contacts are properly lined up.
- Once the new battery is installed, test the sensor to ensure it works.
