Why can my smart device trigger the configured Automation normally for the first time only, but fail to do so afterward?

Please troubleshoot the issue by following the steps below:

Verify that the device is connected to the network and the network connection is stable.

Check if your app is updated to the latest version.

Confirm that the linked scene configured in the app is correct and does not conflict with other linked scenes.

If the Automation rule is created based on environmental parameters such as temperature, humidity, weather or wind speed, execution exceptions may occur due to the device's edge-trigger mechanism. For further troubleshooting, please submit your request via the official feedback channel.

Note on Edge-Trigger Mechanism: The device triggers the Automation only at the moment when the monitored value crosses the set threshold. For example, the Automation will be triggered when the temperature rises from 25°C to 26°C, but will not be triggered repeatedly if the temperature remains above 26°C.
