Hi,
I have a random exception when trying to turn on or off my zigbee lights. My zigbee controller is the HUSBZB-1 usb stick. Most of the time it works, but it fails frequently. This is very frustrating and doesn’t help me with the WAF 
I opened a ticket a week ago about that problem but didn’t receive any reply (see https://github.com/home-assistant/home-assistant/issues/9340).
Am I the only one with this problem?
Thanks.
