My first post so please be kind 🙂

I read all about the SMLight SLZB-06/07 adaptors and plumped for the 07 due to cost here in the UK. I have a HA HAOS installation in Proxmox and have successfully passed the USB details through a VM and HA discovers the device. as I believe it should. The problem is that I am finding it impossible to configure this device and the integration process consistently fails with what look like Python errors in the log. I raised a Github support ticket for this last week:
https://github.com/home-assistant/core/issues/125847

But so far there has been no repsonse, so I thought I would also try here. In the meantime I have also created a bare metal HA 13.1 HAOS installation which also exhibits the same errors.

I am new to HA, the Proxmox installation seems to discover all sorts of services/entities in my home which seem to working OK. I am interested in moving on to see what I can do with senors and other devices if only I can get the Zigbee radio dongle working. I haven't re-posted the error logs here as they are available from the Github post noted above.

All the info I read before purchasing the SLXB-07 seemed to suggest that it should be a case of plugging it in and away you go. This doesn't seem to be the case in reality for me. Can anybody help me get this device working please ?

How are you running the bare metal one?

I installed the Generic x86-64 version following Method 1 of the installation instructions at: https://www.home-assistant.io/installation/generic-x86-64. I have done nothing to the installation at thispoint other than configure the integration/services discovered around the house at first startup. The SLZB-07 was plugged into the machine at this point and was 'discovered' (as it was on the original Proxmox VM) and I tried to configure it from there. At this point it returned 'Failed to probe the usb device' . I then tired to install ZHA - just to see if that found anything different. This found the SLZB-07 on /dev/ttyUSB0 and I chose thedefault EZSP Radio Type. I left the Serial Port Settings as default and continued. At this point it returned 'Failed to Connect (unsurprisingly). I gave up at this point and asked for help.

On your bare metal install, can you enable debug logging for ZHA? https://www.home-assistant.io/integrations/zha/#debug-logging

I Have enabled the debug logging as noted in the URL above. I have tried to configure the SLZB-07, the results are shown in the attached file. Is this what you wanted to see. ?

Perfect. Could you attach the file or DM it to me?

I thought I had. I'll try again.

Ah

#

So debug logging will be in the main Home Assistant debug log

There should be a button to download the whole log file at the bottom. You may need to ZIP it up to shrink it

OK, try again.

Did the system log files provide any pointers towards getting a fix for this problem?

brittle valley Sep 20, 2024, 7:42 PM

#

Is this with the bare metal install? Or Proxmox?

#

As far as the log is concerned, the serial port just doesn't work

pale canyon Sep 21, 2024, 8:01 AM

#

Its from the bare metal installation

Out of interest I have installed the latest HAOS on an RPi using the RPi Imager. Once the initial setup completed I installed the SLZB-07 which was then 'discovered' by HA. I tried to configure it and had exactly the same problem as the previous installations. ZHA configuration also failed with the same issues. I have come to the conclusion that the device is faulty and have raised a support ticket with SMLight. I will wait their coments before proceeding futher. Thanks for your help so far.

It sounds like it. For every USB device with a serial port, there are actually two "halves": the USB descriptor, which names the device and what HA uses to discover it, and then the actual serial port. If the ZigBee chip on your device is broken, the USB part will still work but it will not be communicating with anything
