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.
