For years I have had my zigbee network functional with a ConBee2 zigbee coordinator in my home assistant box.

But this week, devices started to randomly drop off the zigbee network. I could re-pair them and get them in again. But yesterday, it suddenly dropped 24 devices... Sensors, buttons and lightbulbs seem to be the most common ones.

I've restarted the ZHA integration, restarted the docker container, even downgraded to 2026.8.3. Still the same.

I checked the Home-Assistant github repo issues and there are lots of issues regarding zigbee and dropped devices in the last 2-3 weeks.

Does anyone have any suggestions as to why this happened all of the sudden?

The zigbee network has been stable for years before this.

EDIT: At this time I have re-paired all the devices and will see if they start dropping off again.

This seems newsworthy.

The 2 lead project members have left the project for different reasons.

They state that the project will continue as it has always done, since it has a council (which I didn't know), so we shouldn't worry.

There was an argument regarding AI policies in the projects between some of the core contributors, which I think has influenced some of this decision.

There is currently a malicious attack going towards the AUR, in the form of a botnet impersonating git users/maintainers to take over packages and adding a malicious payload.

Arch team is aware and working hard to reset/delete the affected commits and packages.

Not properly released on kernel.org yet, but 7.0 has been tagged on the kernel git repository.
