ZHA Zigbee groups are incorrect assigned to controller device

The problem

Zigbee groups in ZHA are bound to their controller device, which they should not.

A Zigbee group is not a device on its own, and should therefore not be bound to a device.

As a result of the current behavior, scenes cannot be used:

Another area where this goes wrong is when targeting areas or using device automations.

@dmulcahey any update? I would be okay if you just removed the device for now to make Zigbee groups usable through GUI.

Imho its best to represent Zigbee groups as (virtual) devices because they inherently have the same functionality as a single device (e.g one lamp vs group of lamps).

I hear ya 😃 that said, I guess I could make the argument that the coordinator is the virtual device 😛.

Anyway, I’m willing to make the change outlined above to remove the device altogether. As for virtual devices, that would require a bit more thought to ensure that everything works correctly. If you’re ok with this staying the way it is for a bit then I’ll explore it otherwise I’ll get something up to sever them from the coordinator tomorrow.
