Zigbee2MQTT problems with HA Yellow

Configuration Zigbee
1

Hi all,
Read multiple threads on similar topics but nothing seems to work. Have tried uninstalling Z2M, uninstalling mosquitto, reinstalling both, replacing core-mosquitto server with the IP address of my HA, ensuring ezsp is in as adapter, but each time getting this error:

Got this in my zigbee2mqtt config files:

mqtt:
server: mqtt://[my_HA_IP]:1883
user: my_username
password: “my_pwd”
serial:
port: /dev/ttyAMA1
adapter: ezsp
baudrate: 115200
rtscts: true
frontend:
port: 8099

Please help.

I don’t have a Yellow, so not sure, but I think a /dev/tty/AMA1 is a serial port not your Zigbee. The Yellow Specs says that a USB port has SiLabs (which is what you want to use) so should be something like /dev/ttyUSBx, and there may also be a /dev/serial/by-id/blah-blah that points to /dev/tty/USBx that you should use in your Zigbee2MQTT config.

[EDIT] @ jezzalencko Correction, I see now that the Yellow uses a CM4 module (Silicon Labs MGM210P) instead of USB serial and the module is connected via /dev/ttyAMA1 typically running 115200, so I apologize for being incorrect earlier. So back to your earlier question, nothing appears to be incorrect with your setup other than YAML spacing.

as @wmaker states, you should use dev/serial/by-id. That way the config stays consistent even if the port changes. Adapter settings | Zigbee2MQTT

Hi,
I just went through every piece of information about running Zigbee2MQTT as addon on Home assistant yellow and only I found out is info, that support of the radio chip in Yellow ( Silicon Labs MGM210P is experimental and not stable.
Discord chanel is full of questions like that.
You can check it also here: Supported Adapters | Zigbee2MQTT

I think you’re OK.
Looking at the Spec, the Silicon Labs MGM210P uses the EFR32MG21. A lot of people use a Sonoff Dongle “-E” with Z2M which also has EFR32MG21. Some also use the SkyConnect with Z2M which also uses the EFR32MG21. So I think you’re fine. There are indeed a few things that aren’t supported in Z2M for these ESZP based devices, but it works for the most part.
