"It is recommended that you check in the following ways:
1. Whether the mobile phone turns on Wi Fi and the router works normally;
2. When connecting the Bluetooth device, the mobile phone must be connected to the network (because the Bluetooth device needs to be registered with the cloud server before it can be added successfully);
3. If you use Android phone, you must open the location permission of app;
4. The device may have been added. It is recommended to reset the Bluetooth device and add it again;
5. Whether the distance between the Bluetooth gateway and the Bluetooth device is moderate (less than 3 meters), it is recommended to be as close as possible (if there is no Bluetooth gateway, you can skip it and directly connect to the mobile phone)
6. Check whether other users are using the Bluetooth device (because of its characteristics, the Bluetooth device can only be controlled and used by one user, and other users will be offline when using it);
7. The Bluetooth device you added is not our product. Bluetooth products have certain private protocols, so other brands of Bluetooth products cannot be added to our app (even if they are successfully added, they cannot be controlled).
8. If the above situation has been ruled out, and your device is still unable to connect to the Internet, you can provide us with an app account, and we will arrange professional engineers to conduct in-depth investigation for you. "
