"Please check in the following ways:
1. Check whether the device is offline on the app. If it is offline, reset the device and distribute the network again;
2. If your device is a low-power device (devices using batteries and all kinds of sensor devices), in order to ensure the endurance, the low-power device will only show offline in the app after being offline for more than 24 hours. Therefore, it is very likely that your device has been offline, and you need to re network it before it can resume its normal function.
3. If there is still a problem with the device after reallocating the network, we suggest that you first restore the device to its factory settings in the app and remove it, and then add it again;
4. Please check whether the distance between the device and the router (no more than 5 meters without separation, no more than 2 meters with walls, metal objects, etc.) is too far, resulting in the loss of signal transmission. In order to solve this problem, it is recommended that you remove the device first, then reset the device to the distribution network state and re distribute the network. Please keep the network signal good during the connection process.
5. Confirm whether the region of your account is correct. If the region is selected incorrectly, the cloud server where the device is registered is far away from you, which will cause great delay and control failure.
6. If the problem still exists, please provide the app version number and the virtual ID of your device, and we will check the problem for you as soon as possible. "
