Sorry for the slow response t this one.
Do you have a log showing what is received from the device and possibly annotating it with what you think needs to be sent to the device at what time.
We could probably provide a channel linked to the indicator class so you can set this in a rule. If the device is really using a combination of the scene and basic classes that is a real pain as the scene class should provide everything that’s needed (it has methods for button down and button up, double, triple press etc).
Thanks
