More than a dozen Zigbee devices went Offline within an hour of each other

My hunch is that it is due to the health check, but I could be wrong. Here is my post on the issue:

All Zigbee devices are offline

Ok, Eric, thanks for your thoughts. For Number 2: I found a 15’ Ethernet cable, and power cord, and moved the hub as far away as I could. I’ve had smartthings for about 3 years now, and never had a problem. I’ve read this before, so I figured I’d give it a shot. I’ll have to remount everything at a later time. My utility room looks like a spider web For Number 3: I honestly had forgotten that I got a new router, and never went back to hard code the wifi channel to 11. I remedied that this morning. For Number 4: See aforementioned Spider web For Number 5: This is my first go-to solution. I unplugged it for about 1/2 hour again. I had to move it anyways. And… bingo. Most of the devices are coming back online by themselves. The only things left are…

I think a combination of changing my wifi channel and moving the router made the biggest gains. I hadn’t had an issue where the hub was for eons, so who knows. I still have some leak sensors that aren’t online, but I haven’t had a chance to work with them.
