Not sure anyone has had these issues before but I moved all my light groups in HA to ZHA groups in an effort to reduce zigbee traffic and make it more efficient. All works fine no issue, however what i have noticed is that the state of devices do not update, or take a very long time, sometimes 30mins ++ to update to the correct state.
Switching it on and off multiple times as a group usually sorts it and it works for the next few times before the same thing starts happening again. It seems to only happen to the lights I have grouped as ZHA groups.
Any suggestions where I might start to dig?
