"If the device is offline, please check according to the methods listed below:
1. Please check whether the equipment is powered on normally. The equipment may be powered off due to poor contact and other reasons.
2. Whether the device has been powered off or disconnected from the network. If the link is disconnected, there is a process to go online. Please confirm whether it is online after 2 minutes (not all devices support power-off memory function, so the device will go offline after power-off).
3. Please confirm that the network environment signal of the device is strong and stable.
4. Please confirm whether the home Wi Fi network is normal, or whether the Wi Fi name and password have been modified. If so, you need to reset the device and add it again.
5. If the network is normal, but the device is still offline, please confirm whether there are too many Wi Fi connections. You can try to restart the router, power on the device again after power failure, and then wait for 2-3 minutes to see if the device can resume connection.
6. You can try to use mobile hotspot to connect the device to check whether the device is often offline due to network problems.
7. If all the above are ruled out and there is still a problem, it is recommended that you remove the device and add it again. Add it again after removal. If there is still a problem, please select the device in the app user feedback, submit the feedback, provide us with the login account and device ID, and we will submit the technical query reason. "
