And after that

Exception fetching information from http://192.168.124.30:80/cgi-bin/configManager.cgi?action=getConfig&name=MotionDetect

Failed to sync device state for 192.168.124.30. See README to enable debug logs to get full exception

Integration manual reload fixed issue, but until reload I wasn't able to open my doors - that was quite a big problem !

Maybe self reload when this exception happens ?
