All entities becoming unavailable after my migration from deCONZ to ZHA

[Guillaume_Desmidt]

Hello everyone,

I migrated all my devices from deCONZ add-on to ZHA last weekend.
I’ve had no problems and the management is much better integrated with Home Assistant.
However, 2 days later I was unpleasantly surprised to see that all my Zigbee devices had been switched to Unavailable.

However, my stick is well detected and I see it on the Hardware section.

But all entities are in status unavailable:

I’ve tried rebooting the box, changing the USB port key and using a USB extension cable.
I even tried a restore from a backup where all my entities were still up, but nothing helped.
I also reinstalled the deConz Add-on to update my key in the latest firmware but nothing changed.

I’m wondering whether I did the right thing with this integration.

Here’s my setup:

• Home Assistant 2023.10.5
• Supervisor 2023.10.0
• Operating System 11.0
• Hardware Raspberry Pi 4
• Zigbee stick : ConBee 2

Have you ever had this problem? I’m a bit desperate because all my heating is managed by Home Assistant.

Thanks a lot

anything in the logs?

Nothing in the logs despite a restart or reload of the integration
And no error when I enable the debug logging. And it’s hard to diagnose because it’s so verbose.

I found this kind of log, including one on ble monitor integration.
Is it possible that there’s an interface problem on my Raspberry?

So in the end, the solution was quite “simple”. All the apapreils had to be re-paired.
I don’t understand what happened to get to this point.
