Migrate HA from Pi3 to Intel Mini PC - Conbee 2 not working

Bellardita · April 28, 2024, 6:59am

Hello together,

i bought a new mini pc (N95) to migrate my HA installation from an old Pi3.
The migration was no problem. Just a fresh install and a restore out of the complete backup.
Everything works fine, except the ZHA Integration.
I am using a Conbee II from Dresden Electronic and it is working fine in the old machine (Pi3).
In the new machine i reconfigured the Conbee II and it saw the stick on the right port. But it ends up with an error in the last config screen.

I searched for the problem in the internet, but just found some different problems like loosing connections.

I added my dev log.

Perhaps someone hat the same problem and has an idea what i can do.

If possible try a different USB port.

francisp · April 28, 2024, 8:13am

Do you use an USB extension cable ? The Pi3 does not have USB3 ports, but the Mini PC probably does.

Bellardita · April 28, 2024, 8:25am

Thank you both for the quick response.

I do not use an USB extension Cable, but my Mini PC has USB 3.0 and USB 2.0 Ports. I tested both ports.

starob · April 28, 2024, 8:34am

As @francisp said, an USB extension cable is recommended. It moves the stick away from the pc and it’s electrical noise. It will most likely fix your problem.

Bellardita · April 28, 2024, 8:40am

Thanks again for the advice.
I just bouth an 1m USB 2.0 extension cable. It will be delivered tomorrow, so i’m gonna try it tomorrow evening.

Bellardita · April 29, 2024, 5:36pm

Unfortunately the problem is the same while using the USB extension cable.

On the last configuration screen , i get an error “no connection”.
Any other ideas?

starob · April 30, 2024, 6:41am

It shouldn’t matter but please try /dev/ttyUSB0 (or /dev/ttyUSBx where x = 1 or 2 etc. depending on which USB port is used). Also the selected option under “Datenflusskontrolle” does not show anything. Can you check that.

Hedda · April 30, 2024, 9:11am

Is that are bare-metal installation of Home Assistant Operating System directly on the new mini pc or are you installing Home Assistant in a virtual machine and/or as a container under Docker or similar?

Asking as if using in a virtual machine and/or as a container under Docker or similar then you need manually to configure proper USB/device-passthrough as well as enable read and write access access to serial permissions. See → Technical support

Regardless, upgrade ConBee II firmware if you have not already → https://github.com/dresden-elektronik/deconz-rest-plugin/wiki/Update-deCONZ-manually

Bellardita · April 30, 2024, 10:57am

Hello Hedda,

it is a bere-metal installation of HA OS. I first tried an docker installation, but was not so happy with this way of running HA.

I’ll check the firmware update later when i am back at home. Hope to get it managed on a Mac.

I will although switch back to the other “Port”-Name (/dev/…). I read in another thread that it is recommened to use the long version.

Hedda · April 30, 2024, 11:08am

While it is generally recommended to use /dev/serial/by-id for USB device path mapping (because USB port mapping can sometimes change on reboots or be remapped to a different port when add other USB device), I recall seeing several people complaining about difficulties mapping the ConBee 2 using /dev/serial/by-id(but unsure what the root cause and/or solution was for those)

Bellardita · April 30, 2024, 4:32pm

I now tested to switch back to the long Port-Name. Without any effect.

Unfortunately the firmware update i tried did not work either. I used this instruction: How to update conbee II on hassio with deconz/phoscon integration? - #12 by thomas-svrts
It fails with “bootloader failed”.
Irritatingly, it doesn’t find suitable firmware as described in the instructions; I have to select it manually.

Normally i would thought there is a problem with the conbee 2 hardware, but as i put it back to the RP3 it works like a charm.

I although tried today a completely new restore of the new N95 from a fresh backup from the RP3, but this does not fix it either.

Hedda · April 30, 2024, 7:42pm

Try with a USB extention cable as sometimes some dongles have trouble making proper physical electrical contact in some chassis and then it can help to use a USB extension cable which has thinner plug and port

Bellardita · May 1, 2024, 6:34am

I am using an extension cable. 1m Amazon Basic USB 2.0 … But it although don’t work.

I think it has to be related, that i have made an restore on other hardware (vom PI to X86).

francisp · May 1, 2024, 6:56am

That should be no problem.

Bellardita · May 1, 2024, 7:41am

Hmmm…

Any other ideas? Shall i delete the ZHA Integration and try a new setup?
I have read that Zigbee2MQTT works better.
At the moment i only have 9 devices paired with the Conbee, so it would not be that hard to start the Zigbee Integration from scratch

francisp · May 1, 2024, 7:43am

Can’t hurt to try. But if it is a hardware problem between your USB-ports and the Conbee, it won’t help.

Bellardita · May 1, 2024, 2:09pm

I’ve now updated the firmware. But the problem is the same. No connection.

On the last screen, the empty choice under “Datenflusskontrolle” is although with empty value.

Bellardita · May 3, 2024, 9:46am

I gave up and bought the SkyConnect Stick. The migration out of the backup does not work, but now i added all the zigbee devices and it is now running again.
