Can't use Conbee 2 for ZHA interation

[Ir0nhid3]

The problem

I tried to change from Deconz to ZHA and removed all devices, entities and add-ons. Unluckyly I had to try it serveral times with even less luck - the integration does not work with my conbee 2 anylonger. The device is not recognised anylonger. A couple of years ago it was no problem. Could you please fix that? Some of my devices are not supported from deconz.

How are you running Home Assistant? Docker? A VM?

Are you manually entering the serial port path or are you selecting the Conbee from the ZHA setup screen?

[Ir0nhid3]

On Proxmox Container with that one: https://tteck.github.io/Proxmox/#home-assistant-os-vm

[puddly]

Try unplugging the Conbee, plugging it back in, and remapping it to the HA OS VM. It's common for the Conbee to "disconnect" after communication with it stops, breaking some hypervisors.

[Ir0nhid3]

I will do that again, but in deconz it works fine.

Is the deconz addon uninstalled?

[Ir0nhid3]

Is the deconz addon uninstalled?

Yep, so the device is not used elsewhere. In the first steps it is recognized fine, though.

USB serial devices have two parts: the USB side and the serial port. The first step you see just shows the USB information, it doesn't try to communicate with the device in any way and doesn't know if the serial port is functional. When you continue, ZHA actually tries to communicate with the serial port. The error you see is because ZHA can't communicate with the Conbee 2.

We have many Conbee 2 users and this is the first issue reported for the Conbee 2 in months so I'm inclined to believe this is a Proxmox + Conbee issue with your setup.

Are you running deCONZ as Home Assistant OS addon or in another VM or container?

It could be, but it does not make sense in my eyes, if the same hardware runs in the same environment with another add on. I would not know why this does not work.

deCONZ runs as an addon. The hardware in Home Assistant is shown as expected. And even if that path ist manually used it does not work.

[Ir0nhid3]

Update: the same USB port does not work. Another works from out of the box why so ever.

I have the same issue. it happened after the new HA update and installing some add ons. when I try to reload as it states the firmware is incompatible. the repairs links empty and I can't see any firmware updates available on their website. any suggestions would be great! I have the Connect zb1 and bought it a week ago and worked fine until the HA update last night.

@FloraFiat this issue is about the Conbee II. If you're having issues with a ZBT-1, please open a new issue and attach diagnostic information for the ZHA integration and a debug log.
