@Tiwas actually that’s what the Homey app already can do you can call multiple cameras in one flow (with multiple cards) and it will behave the same as the grouping function Eufy provided.
Actaully the grouping in the Eufy app is really slow.
But grouping in the Eufy app in Homey, I’m not sure about that, it will create a lot of overhead and in the end it wont be any faster, it only saves you some flowcards
