New Skyconnect not working in Proxmox

Hardware
5

I have the same issue. I’m running HAOS in a proxmox VM. On the host, lsusb identifies the Skyconnect as:

Bus 001 Device 003: ID 10c4:ea60 Silicon Labs CP210x UART Bridge

I’ve confirmed this is the right device by adding it, running lsusb, removing it, running lsusb. This exact device appears only when the Skyconnect is inserted.

In Proxmox I’ve passed the device through to HA as the USB port 1-2. “qm info usbhost” on the host confirms the passthrough:

Bus 1, Addr 3, Port 2, Speed 12 Mb/s
Class 00: USB device 10c4:ea60, CP2102N USB to UART Bridge Controller

In HA ssh, a “hwinfo --usb” shows that the device is visible within the HA VM (see full output below). I’ve rebooted the host, restarted the VM, and restarted HA from HA settings. In HA, Setting → Devices & Services, nothing appears as autodetected.

nope I am sure it is the correct one. It’s the only USB device connected and when I remove it I no longer see it in the list. Could it be they are sending out devices flashed incorrectly??

Goto UI->System->Hardware, click on All Hardware. You should see a ttyUSBx for your SkyConnect and you should see attributes like:

.....
ID_BUS: usb
ID_MODEL: SkyConnect_v1.0
ID_MODEL_ENC: SkyConnect\x20v1.0
ID_MODEL_ID: ea60
ID_PATH: pci-0000:00:05.2-usb-0:1:1.0
ID_PATH_TAG: pci-0000_00_05_2-usb-0_1_1_0
ID_REVISION: '0100'
ID_SERIAL: Nabu_Casa_SkyConnect_v1.0_2eba2b499514ed88a6d5b99be054580b
ID_SERIAL_SHORT: 2eba2b499514ed88a6d5b99be054580b
ID_TYPE: generic
ID_USB_DRIVER: cp210x
......

Do you see “Nabu Casa” or SkyConnect" anywhere in the list?
If not then, I don’t know… I don’t use Proxmox (but use libvirt/virt-manager).
My wild guess would be that Proxmox is perhaps passing the device as a “serial” device instead of a USB device, but is presenting it to the Guest as a serial USB device with its own USB attributes, thus any attributes that HA may use to indicate its a SkyConnect USB device is lost.

I am having this same issue. My SkyConnect was purchased from ameriDroid and was part of the 8th Batch (Mid November).

The one I purchases previously (February 2023) for another installation showed up as Nabu_Casa_SkyConnect_…. I thought it was strange it was identifying as usb-Silicon_Labs_CP2102N_USB_to_UART_Bridge_Controller_ba9bdf3453b7ed11885b955938a92db5-if00-port0.

Tried on my existing system, a new VM, and on a newly flashed RPi

None of them auto discover the ZHA integration but the device appears as an option if you manually setting up the ZHA integration but will not be recognized for the MultiProtocol. Doesn’t show in the hardware section to configure the multiprotocol.

The Silicon Labs Multiprotocol fails to start with an error that it cannot determine the firmware.

With the SkyConnect plugged in to your host without passthrough to the VM, try:
udevadm info /dev/ttyUSB0 (or what ever USBx its using).

Do you see any attributes with Nabu Casa or SkyConnect?

11

Thanks for following up!

This Skyconnect mounts to /dev/ttyUSB0 (the zwave and conbee mount at /dev/ttyACM0 and /dev/ttyACM1 respectively). Running the command directly in the host and in the Hass VM it returns

Looks like there is a batch that didn’t get the correct ID info flashed to the usb chip. I"ve seen a similar post elsewhere.

It may not auto-detect, but probably still works if you manually configure ZHA.

13

That explains a lot…I would raise the issue with AmeriDroid and see what they say.

Incorrect IDs is likely what keeps SiLabs Multiprotocol Add-on from recognizing and reflashing the device.

In the manual attempt to reflash, it seems the error is due to bellows.config and not so much the IDs. If its possible to fix this, then maybe there is hope.

14

BTW, I came across an article someone posted on Discord. Its about another way to manually flash firmware for use with Multiprotocol Add-On. The article is about flashing a Sonoff Dongle-E, but says it also works for SkyConnect.

15

I also had one of the bad Nov batch devices. The box was labeled “S/N 242303”; apparently some other devices with a similar serial number were affected. Nabu Casa support told me how to assign the correct device name. After running the steps below, the device is auto-recognized by HA.

  1. Install Advanced SSH add-on, disable Protected mode in the add-on settings.
  2. Connect to SSH terminal and run:
# Enter the OS container (make sure "Protection mode" is disabled in the addon)
docker exec -it homeassistant /bin/bash

# Build `cp2102x-cfg`
apk add alpine-sdk libusb-dev
git clone https://github.com/irrwisch1/cp210x-cfg
cd cp210x-cfg
make

# This command should list only a single device
./cp210x-cfg -l

# Finally, program it.
./cp210x-cfg -N 'SkyConnect v1.0' -C 'Nabu Casa'

# Unplug the SkyConnect and plug it back in. You should see a SkyConnect entry here when using the below command
ls -l /dev/serial/by-id/

These instructions dont seem to change anything for me.
I tried on both HAOS and directly on my Proxmox host.
When I unplug and plug it back in the name seems to remain the same.

Update:
nevermind! After doing it like 10 times it finally stuck.

I thought it won’t work for me. But after I saw your comment, I also tried 10 times. After this magic number it started fully working again, thanks I guess :smiley:

All good now, Thx a lot for this solution!

So, I’m new to the HA arena. Do I paste this whole code into SSH, or are there changes I need to make to the code?

I bought a SkyConnect stick a few months ago, I tried the solution above but it doesn’t work.

I’m using Home Assistant in a VM, Windows 11 being the host, and everytime I retsart the PC, the stick shows as “Crystal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light” under the VM USB settings.
(I don’t know what “myAVR mySmartUSB light” is, I’m not sure it was there before, I just noticed it. Perhaps it appeared after I did the steps mentioned a few posts above… I don’t know…)

I have to delete the device from the USB settings, physically remove the stick from the USB port, plug it back in, then add it back in the settings. Only then it will show as “NabuCasa SkyConnect v1.0”. Otherwise, ZigBee doesn’t work. It’s REALLY annoying to have to do that everytime.

S/N on the box is 242303, if that matters.

Should I contact Nabu Casa and ask for a replacement?

What VM software ? The Skyconnect is not faulty, Windows 11 is just not a good platform to run HA on.

VirtualBox. Could it be the culprit? Forgot to mention, but it always shows as SkyConnect under device manager in Windows.

I just received a SkyConnect from AmeriDroid and am having the same issue.

This looks like the improper USB setting. I’ll try the fix posted to see if that fixed it.
You’d think they’d have fixed the stock by now.

That fixed it. Thanks for posting this.
Funny, I had the exact same serial number on the box listed above.

Very similar setup to you. Did you ever find a more elegant workaround? Moving from VirtualBox to ProxMox is not an option as need the host to be windows. However every restart of host, virtualbox fails to pickup the SkyConnect and have to play unplugging, resetting, adding USB into virtualbox and cross fingers
