I have noticed that in my Groups tab in ZHA there is Default Lightlink Group with the group id: 0x0000. In Devices section it only lists my Coordinator two times (according to this github issue thread this is only a display bug).
My question is what is Default Lightlink Group in ZHA Zigbee groups?
I tried to find the answer on web, but haven’t found anything that directly answers this question. I want to know this in order to safely delete this group or keep it in case it’s an essential component of ZHA.
