Entire Zigbee network bounced

Configuration Zigbee
1

I’ve now had my entire Zigbee network go offline (all Zigbee devices unresponsive, greyed out in the Dashboard) for several seconds then come back twice. I’m currently on Core 2023.12.4. The first time it happened I was on either 2023.12.1 or 2023.12.3. I’m using ZHA with a SONOFF Zigbee 3.0 USB Dongle. This was in the log seconds after it happened the 2nd time:

[0x0AC5:1:0x0006]: async_initialize: all attempts have failed: [DeliveryError('Failed to deliver message: <EmberStatus.DELIVERY_FAILED: 102>'), DeliveryError('Failed to deliver message: <EmberStatus.DELIVERY_FAILED: 102>'), DeliveryError('Failed to deliver message: <EmberStatus.DELIVERY_FAILED: 102>'), DeliveryError('Failed to deliver message: <EmberStatus.DELIVERY_FAILED: 102>')]

Anyone else having an issue like this? What’s the cause?

I have the same setup, I’m not having that issue. I’m sure you’ve already analyzed this but what, if anything, has changed recently? Move a Zigbee device or the dongle? Add a new device? What’s the makeup of your Zigbee network? Most of mine is hard wired with only a couple wireless devices, it could be if you have a lot of wireless devices that it’s queuing up too much or perhaps you are conflicting with your wifi network.

Nothing has changed except for HA updates. Never had the issue prior to the December updates. I’ve got 83 devices mostly battery powered sensors and AC powered outlets/repeaters. I think it may be this issue except it seems to be happening more frequently to the users posting there.

Same here, network was rock solid till the 12.X updates came about. Now I get reinitialisation of ZHA every couple of hours and this causes devices to drop off the network.

Up 12.4 fixed some items but this is still happening. I cant see it in the logs but it is quite clear when you didnt do a restart but when you view devices it says unavailable 2h ago for example
