The smart scenes fail to be executed in the Mi Home app

If the smart scenes fail to be executed in the Mi Home app, please check the following troubleshooting methods:
1. Check whether the related devices are connected to the Mi Home app;
2. Restart the router to check if the issue persists;
3. Check whether the device firmware and the Mi Home app are the latest versions;
4. Control the camera alone to see if it can work properly;
5. Check whether the system time of the mobile phone is normal (faster or slower);
6. If the smart scene involves a gateway and sub-devices, you can adjust the distance between the gateway and the sub-devices to ensure that the sub-devices are online.
