If a Tapo sensor will not pair with the Tapo H500, these are the checks from Tapo’s pairing guide.

What This Problem Means

The sensor is not joining the hub.

Common Symptoms

• The sensor is not found
• Pairing times out
• The sensor light does not blink

Safe Checks You Can Try

1. Pull the battery tab

Tapo says to pull out the battery insulation tab.

2. Move closer

Bring the sensor close to the hub while pairing.

3. Reset the sensor

Reset the sensor until its light blinks rapidly.

4. Start pairing from the hub

Start adding the sensor from the H500 in the Tapo app, and keep the sensor close to the hub until it is found.

5. Reboot the sensor

Take the battery out and put it back. If the light is dark or dim, fit a new battery.

6. Check the region

Tapo says the region codes on the labels must match (UK/EU sensors with UK/EU hubs).

When To Contact Support

If none of these checks fix it, contact Tapo support through TP-Link’s UK support site, with the model and hardware version from the label on the device.
