I wish that there was a way to use the HUSBZB zigbee stick that separated it from Home Assistant. I think ZHA runs well but my only issue is that I hate that every time I have to restart Home Assistant it seems like it has to reinitialize or reconnect to everything and for a little while devices can be sluggish until you operate them a few times then everything starts working well. If zigbee was separate from Home Assistant this problem wouldn’t exist.
I know there is zigbee2mqtt but I don’t believe this works with the HUSBZB and I don’t really want to change controllers at this point. /rantoff
