Can't connect generic EFR32MG21 zigbee module with CH340 serial to USB chip

[rain ocean]

I'm trying to connect a Zigbee USB dongle to ZHA, but it'll just say that it can't open the device. The documentations say that the Home Assistant Connect ZBT-1 is based on the same chip, so I don't know why it's not connecting. I am passing through the device into a Docker container, and when I run bash inside, the container recognizes the device. My end goal is to be able to connect the Zigbee stick to home assistant. I have also looked in the hardware menu under System, but there is no option to list devices. Thanks in advance to anyone that chooses to help me

Please share your compose file and ls -l /dev/serial/by-id/.

[rain ocean]

docker run -d \
  --name homeassistant \
  --privileged \
  --restart=unless-stopped \
  -e TZ=America/Montreal \
  -v /root/config:/config \
  -v /run/dbus:/run/dbus:ro \
  --network=host \
  --device /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0 \
  ghcr.io/home-assistant/home-assistant:stable

This is what the ls -l command outputs when run in the docker container
crw-rw---- 1 root root 188, 0 Dec 23 16:49 usb-1a86_USB_Serial-if00-port0

device is actually not needed if you use privileged.
Try to flash the coordinator with a firmware.

[rain ocean]

what would be the best firmware for it?

[keen trout]

Not sure for this model and ZHA.

[hallow tiger]

what specific device is this, anyways? firmwares generally need to be built to match a particular device.

[rain ocean]

It's an EFR32MG21 chip

It's not branded

[keen trout]

Looks like a ZB-GW04.

[hallow tiger]

Which is one of the devices that has firmware available from https://github.com/darkxst/silabs-firmware-builder

the board should have an identifying mark visible through the case saying the type and revision if so

[rain ocean]

It's a v1.2 from what I can see on the board

[hallow tiger]

right, then go over to https://darkxst.github.io/silabs-firmware-builder/ and flash away.

[rain ocean]

Already on it, thanks

Says this is the current firmware

[hallow tiger]

might as well upgrade it, but the build it came with should be working.

[rain ocean]

Firmware is upgraded now

I'm gonna go plug it in and see what happens

[hallow tiger]

unfortunately, given that it connected fine to the pc you used for the upgrade and already had a fairly recent firmware, it seems likely that you're hitting some other problem :(

but who knows, maybe that'll do the trick.

[rain ocean]

It failed the first time, but it now says network formation when i clicked the second time

Ayyy it worked
