It happened to me (on one of my Boom's) and despite many attempts I could not get it to connect to Channel 6. Changed it to 1 or 11 and it connected immediately. I have seen the same thing when first getting Sonoff devices connected.
I am using Unifi AP's (x4) with the Unifi Controller and I have just remotely changed the channel on my Garage AP to 6 and the Boom immediately disappeared from LMS. Switched it back to 1 and it came back on line so easily repeatable. A second Boom located in my office on a different Unifi AP has no problem with Channel 6. There is no channel interference and none of my neighbours are using channel 6 according to the Controller: [image: https://i.imgur.com/nBRQAVW.jpg] Not offering a technical reason, simply a possible solution to your woes. I could take the office Boom to the Garage and see if they both behave the same way but no reason to do so as I have a working solution. ------------------------------------------------------------------------ Heuer's Profile: http://forums.slimdevices.com/member.php?userid=2543 View this thread: http://forums.slimdevices.com/showthread.php?t=112325 _______________________________________________ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
