I’m trying to find a simple way to create a group which combines the availability status of multiple devices.
It should behave the same way a regular group does, but display the availability.
So - lets say I have 5 devices in that group - as long as one of them is available, the group should show “available” or “on” - or the other way around, the group should show “unavailable” or “off”, only if all devices are unavailable.
Is there a simple way to do that? - it should be simple, because the devices will probably change in future and I don’t want to have to edit dozens of template sensors every time they do … it should be as simple as dragging it from one group to another
