I’m tearing my hair out trying to troubleshoot devices dropping off the network. The devices dropping off seem to be primarily Aqara door and motion sensors. I have no idea what to try next. Here’s my system:
Home Assistant running on a VM in Unraid.
Running ZHA on a Skyconnect. The Skyconnect is on a USB 2.0 port with a 36" USB extension cable. I tried using a USB 3.0 port and it doesn’t seem to matter. I also tried a Sonoff 3.0 USB Dongle Plus–ZBDongle-E.
ZHA is set to Channel 15. My Wifi Router 2.4GHz band is set to Channel 6 and my two range extenders are set to Channel 11.
My Zigbee network has 72 devices. 39 of these are battery powered. I have a mix of Aqara, Sonoff, Ikea, Philips, Sengled, and Third Reality devices.
Thanks. The Hubitat info was good reading. I’ve been reluctant to change my Zigbee channel for fear that I would have to repair all my devices, but maybe that’s what I need to do.
I tried this but couldn’t find the relevant info in the file. I searched for “utilization” and “%”, but neither of these terms were found. I also tried searching for “15” (my Zigbee channel) and found several entries for “depth:”.
There are 45 diagnostic entities that are not enabled. Might one of those provide helpful info to solve the problem?
I just looked at this as I began to migrate from a conbee to sonoff and found this in the json file.

If using latest ZHA integration then normally it is only Zigbee end devices (usually just battery-powered products) that will need to be re-paired, as normal is that all always-on Zigbee Router devices (usually mains-powered products) that have permanent power and are connected will automatically change channel → https://www.home-assistant.io/integrations/zha#defining-zigbee-channel-to-use
Regardless, if possible begin by setting non-conflicting static Wi-Fi channel(s) on your Wi-Fi devices (Wi-Fi router and WiFi access points, etc.) as that is usually much easier than changing Zigbee channel.
Yes I have close to 80 devices and all reconnect on a Chanel change. Im running into the same issue, 1 or 2 bulbs will drop off every day or 2, I have no battery powered routers, I think my channel is just congested.
I’m using 25 now but doesn’t matter, I think I just have too many devices, zigbee isn’t meant for that I suppose. As you can see every channel is congested. Could switch to 15 but then 15 would be where 25 is now. Can’t win with 2.4ghz congestion I didn’t have this issue with Hubitat BUT I was using 2 hubitat hubs, 1 just for bulbs and 1 for switches and battery devices, which seemed to work a lot better.
