Devide and rule Sonoff 4-Channel?

I run some 25 MQTT devices including Sonoff, LSC, Shelly and Maxcio and Gosuna plugs. A Sonoff 4 Channel Pro operates 4 lights in adjacent rooms. The switches may be individually toggled in the app’s sub menu. But, how to attribute the 4 channels to the correct rooms and use the 4 switches individually in flows?

Not sure if I understand you right, you can use the switches in flows individually:

But it is not possible to assign each switch of a Sonoff 4 Channel Pro to a individual zone/room.

thanks, took some work, including deleting and re-installing the 4- channel device. After that it was solved. Btw, it looks a lot different in version 5!
