Every 8 hours or so all of my ZigBee devices (motion sensors, open/close sensors, water sensor) lose connection.
Sometimes they show up as still connected in the app, and even seem to be sending temperature information, but don’t register when they open or close or when motion occurs and thus not triggering their automations.
Sometimes they show up as simply disconnected in the app.
Usually if I pull out and then replace the battery in one of these devices they will connect again and many of the other devices will also connect automatically. Only to lose connection again 8 hours later.
Currently doing a reboot of my hub, leaving it disconnected for 1 full hour. Hopefully this will work.
The issue has been happening for about a week now.
Zigbee and WiFi can overlap each other. It’s possible you may have your Zigbee channel and WiFi channel interfering with each other. Use a WiFi analyzer app and see what’s around you, because it could be your neighbor’s WiFi that’s hammering away at your Zigbee network. Usually, changing channels on one or both will solve the issue, but you need to know what’s around and what’s available so you’re not guessing.
What’s your zigbee mesh like in terms of available repeaters distance between them, including the hub. Sounds like a interference and/or range issues. You could also have a zigbee repeater failing and causing issues in your mesh.
To add to the thought above, also check for any misbehaving zigbee router devices, especially some older GE switches and even their newer outlets (non power meter capability ones). I have one of their outlets causing issues like this and I’m about to ask for a replacement.
Been a while since I posted here. I did end up changing the channel that my zigbee devices were using to channel 25 (previously they were on 24). This solved the problem and things have been working well for the past month.
And then 2 days ago they started back up again.
I’ve tried switching to a different channel and then switching back and that usually solves the problem for a few hours and then we are back to being disconnected (or worse…it says it’s connected but it isn’t).
