Fail to add a sensor?
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
- Please make sure your phone is within 5 meters of the Sensor.

- When pairing, check if the blue indicator light of the Sensor is flashing (by poking the Sensor for 1 second and then releasing it, the Sensor's indicator light flashing means it is in setting mode, and if the indicator light stops flashing, it means the pairing is successful).

- Make sure that the Hub firmware is the latest version (Menu >>> Hubs >>> Hub Settings >>> Firmware Version >>> Click *Check Update* to check if the Hub firmware is the latest version).

- Add a sensor without correct steps.Please re-add the device according to the instructions on the app.

- Do not turn off your phone's Bluetooth and network (Android needs to grant Bluetooth permission).
