How to have ZHA group entity off unless all its lights are on

Hi! I’ve successfully configured my control system using ZHA with a ConBee II dongle and several IKEA Zigbee bulbs and switches.

I’ve built two ZHA-based groups, and they work correctly so I can turn on and off all the lights in the group with a single command.

However, I see that the group is considered on when just one of the lights in the group is on.
I’d like to change this behaviour, so the group is considered off unless all the lights in the group are on.

I see that, for manually-defined groups, this is achieved using the all configuration variable. I’d like to know if it’s possible to achieve a similar behaviour for ZHA-defined groups.

Thanks!
