Hi, if you want to speak Dutch, please use the Motion Blinds NL thread, I’ll answer English here.
My Homey is turned off at the moment and I’m not near it so I cannot check.
Although Homey has flow cards for all devices of a type, I normally use the group app to combine devices:
Or I create flows that name all the individual devices. The reason is that more often that not, all is never really all. That way I can separate sunblinds and rollerblinds more easily for example.
