Why can't a delay plugin be added after binding a manually executed Tap-to-Run scene to a Scene Switch button?
Learn about functional limitations when adding delay plugins to scenes bound to Scene Switch buttons.
Currently, there are functional limitations to the rules created through the scene switch panel: after binding to a button, only device control actions can be added, and other actions such as adding or modifying delay plugins are not supported.
If you need to use the delay function, it is recommended to add the plugin before binding the scenario to the button. If the binding has already been done, you need to delete the existing scenario and re-edit it.
