Group Sensors should allow other group sensors as members

I would like group sensors to be able to contain other group sensors.

Potential use case:

  • There is a house_motion group sensor that combines several motion sensors throughout the house. It’s set so that the group is on if any sensor is on, and off when all sensors are off
  • There is a empty_house group sensor that is on when my phone, my watch and my wife’s phone are all not on local wifi.

I would like to have a top level group that contains both the empty_house and house_motion groups that I’d configure to only be on when empty_house and house_motion are both on. Then I could use that to trigger an automation and/or send me a notification so I could check my cameras and see what set things off.

This is already possible. Please show the configuration you are trying to use.
