1, background restriction: iOS system will restrict the background activities of applications to save battery life and resources. As a result, the automation cannot be triggered normally when the Mijia App is not opened. You can try to check and adjust the background activity permissions of the application in the settings of iOS to ensure that Mijia App can trigger automation normally when it runs in the background.
2. Conditions are not met: when setting automation, some conditions are set, such as time and equipment status. Not opening the App does not meet these conditions and will not trigger automation.
