Anyone have Zigbee or Z-Wave USB adapters that is not already whitelisted for USB discovery in HA?

Back-story: Home Assistant developer bdraco recently added a new user-friendly feature for automatically discovering USB adapters for Home Assistant core integrated components like ZHA (for Zigbee) and Z-Wave JS integrations as now noted in their documentation.

Zigbee USB adapter discovery:

https://www.home-assistant.io/integrations/zha/#discovery-via-usb-or-zeroconf

ZWave USB adapter discovery

https://www.home-assistant.io/integrations/zwave_js/#discovery-via-usb

These integrations in turn rely on the USB Discovery integration which watches host for USB devices:

https://www.home-assistant.io/integrations/usb/

This new feature means that if a user plug-in a USB adapter with a whitelisted identifier it will be auto-detected by Home Assistant OS and notify users that new devices have been discovered, however, for that to work automagically we first need a list of some identifying information about compatible USB devices added to the whitelist in each integration component.

I think it would be much appreciated by new users if existing users in the HA community that already has a working ZHA compatible Zigbee USB adapter that is presented with a unique description could give feedback here on its IDs and description so that it can hopefully be auto-detected with a “friendly name” in the future.

What is currently needed to automatically detect a Zigbee USB adapter is its “Product Description String” (a.k.a. device descriptor/descriptors) in combination with its “Vendor ID” (a.k.a. vid hex) and “Product ID” (a.k.a. pid hex).

Once we know a device descriptor, vid and pid we can attempt to get those whitelist those in Home Assistant core and its ZHA or Z-Wave JS integration components.

Using this detection method it is only possible to detect USB adapter that are configured with a such unique custom, which is only possible to configure on Zigbee USB adapters that uses USB-to-UART converter chip with a writable EEPROM (like WCH CH340B, FTDI FT231 series, or Silicon Labs CP210x series).

This means that if the manufacturer of your USB adapter has been cheap and used a USB-to-Serial bridge chip without a configurable EEPROM or missed configuring a custom “Product Description String” then Home Assistant OS can probably not auto-detect it as a unique device.

Note that if you as a customer would ask manufacturers to add this as a feature for new USB devices it should be noted a manufacturer only need to configure the “Product Description String”, and device manufacturers should not need to change the original VID or PID (as doing so would require providing custom drivers for the operating system).

FYI, omerk from Electrolama wrote that their upcoming zzhp and zzh2 USB dongles will have FT231X USB-to-UART bridge + come with customised “Product Description” strings so can be discovered.

The original zzh will however keep using the CH340E without EEPROM so can not use USB discovery.

#3

FYI, users who got one of the first batch ITead Sonoff Zigbee 3.0 USB Dongle Plus (which has Silabs CP2102 USB-to-UART bridge with programable EEPROM) report that ITead has, unfortunately, forgot/missed or chosen not to configure their own custom “Product Description” string to it. :frowning:

That means that those cannot use USB discovery even though their hardware supports it, which is a real bummer. IMHO potential buyers should really write to them and ask them to configure this on them.

This would not be hard for ITead to fix as all they need to do is write their own “description” to the EEPROM of the CP2102N USB-to-UART chip when they flash the firmware on it before packaging it.

Hello, I was just wondering if anyone has experienced this issue before, Is set it up originally and it was all working correctly. Then I tried installing ZIgbee2MQTT and it failed, I have deleted Zigbee2MQTT and tried going back to ZHA but it keeps failing, I get the error Failed to set up check the logs

I have tried to uninstall it Remove the Zigbee database file, Go To a backup of home assistant before I installed Zigbee2Mqtt.

When I reinstall ZHA it finds the serial device path to the USB without any Issues,

Created configuration for CP2102N USB to UART Bridge Controller, s/n: Serial Number shows up - Silicon Labs.

But I get this error image

Any Ideas What I am doing wrong?

#5

You are sure Zigbee2MQTT is not running anymore ?

#6

Yes It’s definitely not running or installed

#7

@Luke1 off-topic for this subject so please suggest that you create a brand new thread for that instead.

#8

FYI, got a reply from ITead that they will change default “CP2102 USB to UART Bridge Controller” text in the Product Description String value field to “Sonoff Zigbee 3.0 USB Dongle Plus” in their next batch.

They already tested that USB discovery works in Home Assistant on Linux, but the change will require them to generate and provide a custom device driver for Microsoft Windows-based operating systems.

Why it would require them to generate and provide a custom device driver I do not know as changing only changing the “Product Description” and leaving the original VID and PID should not require that.

ZigStar Stick USB discovery to be added here (PR patch by @mercenaruss = the maker of ZigStar):

ZigStar is by the way an open source hardware (USB dongle is based on CC2652P + CH340B chip):

@tteck reported in another thread that the very latest batch of Sonoff Zigbee 3.0 USB Dongle Plus that has shipped now looks to have a unique product description value written to CP2102N EEPROM.

The question that remains to answer is which exact product description that ITead chose to go with.

Perhaps people with new batch can verify product description and test changes from this pull request:

https://github.com/home-assistant/core/pull/58166

That uses wildcards so think it will work as long as product description contains “sonoff” somewhere(?).

#12

@tteck posted serial path old and new batch shipped from ITead with updated Sonoff Zigbee 3.0 USB Dongle Plus product description in https://community.home-assistant.io/t/sonoff-zigbee-3-0-usb-dongle-plus-by-itead-is-based-on-texas-instruments-cc2652p-can-be-pre-ordered-for-10-99/340705/174

Old ID

/dev/serial/by-id/usb-Silicon_Labs_CP2102N_USB_to_UART_Bridge_Controller_a4766cbfb593eb11b7611b4f3d98b6d1-if00-port0

New ID

/dev/serial/by-id/usb-ITead_Sonoff_Zigbee_3.0_USB_Dongle_Plus_201e5if00-port0

Serial path adds “usb-” + vendor as prefix and some ID and port-number as suffix + added underscores.

So assume new product description is “Sonoff Zigbee 3.0 USB Dongle Plus” (without underscores).

Again, can someone with new batch HW test PR? → https://github.com/home-assistant/core/pull/58166

I do not own a dongle from the new batch with the new product description so can not test it myself.

#13

FYI, ITead now posted a script/program that should let users themselves update the product description on already shipped dongles to supposedly match description already written to latest batch of dongles:

https://www.facebook.com/SONOFF.official/posts/2927251720919807

Tested it myself on a Windows 10 computer and it did not work for me (it closed without any messages).

Sadly ITead did not just release a script tool based on this open-source cp210x-program by VCTLabs:

https://github.com/VCTLabs/cp210x-program

Again, the point of having a unique custom product description is to allow USB auto-discovery in ZHA:

FYI, OpenMyDog submitted a new PR for ZHA discovery of Sonoff Zigbee 3.0 USB Dongle Plus:

#15

FYI, Home Assistant 2022.2 release notes now menation USB discover of Sonoff Zigbee Dongle Plus:

https://www.home-assistant.io/blog/2022/02/02/release-20222/#all-changes

Again, this only applies to newer batches of shipped dongles the initial batches missing ID in CP2102N, as if your dongle does not have this unique description then it will be discovered as dongle for Z-Wave.

FYI, looks like Home Assistant will soon support automatic USB discovery for the new ITead’s “Sonoff Zigbee 3.0 USB Dongle Plus V2” model “ZBDongle-E” based on Silicon Labs EFR32MG21 if merge:

  {
      "vid": "1A86",
      "pid": "55D4",
      "description": "*sonoff*plus*",
      "known_devices": ["sonoff zigbee dongle plus v2"]
    },

It uses a WCH CH9102F (CH9102/CH340 device drivers) for USB-to-UART chip which has VID (Vendor ID) "1A86 "and PID (Product ID) 55D4 as well as the new USB product description identifier “sonoff zigbee dongle plus v2” on this variant.
