You can group lights like this in Home Assistant.

You can also do it in ZigBee creating a group, if you just use the group in HA then you get the cascading "light 1 change, light 2 change, light 3 change, light 4 change", but with a ZigBee group it goes "light group blah change" and they all go at once.
