Hass OS & Odroid N2+ & HM-MOD-RPI-PCB & Homematic Addon

Greetings,
I got my new SBC, an Odroid N2+. Next step should be the migration from my working Raspi 4

I use the add pcb HM-MOD-RPI-PCB
From the electricle point of view, it will fit to GPIO Ports on Odroid N2+

How to enable the serial communication trough the GPIO Pins?
I have allready enabled the overlay in /mnt/boot/haos-config.txt

# cat /mnt/boot/haos-config.txt 
# Uncomment this to enable GPIO support for RPI-RF-MOD/HM-MOD-RPI-PCB
overlays=rpi-rf-mod

The cmdline.txt File was not changed

# cat /mnt/boot/cmdline.txt 
console=tty0 console=ttyAML0,115200n8

After booting the System, I found a new Device in /dev and I guess, this will be my serial device File for communication with my homematic radio, right?

# ls -l /dev/raw-uart 
crw-------    1 root     root      238,   0 Oct 12 15:24 /dev/raw-uart

Next step I tried was to configure my Homematic Addon via WebGui
This is my working Raspi config, I only changed the devicefile to the new once

rf_enable: true
wired_enable: false
hmip_enable: false
rf:
  - type: CCU2
    device: /dev/raw-uart
wired: []
hmip: []

After hitting the Save Button, I get an error.

Fehler beim Speichern der Add-on-Konfiguration, Device '/dev/raw-uart' don't match the filter subsystem=tty! in HomeMatic CCU (core_homematic). Got {'rf_enable': True, 'wired_enable': False, 'hmip_enable': False, 'rf': [{'type': 'CCU2', 'device': '/dev/raw-uart'}], 'wired': [], 'hmip': []}

The filter come from HomematicAddon → config.yaml

Does anybody have this setup running?
Or any suggestions what I am doing wrong?

Thx a lot and best Regards,
Daniel

Hey Daniel,
Did you manage to get this working?

I am trying to get a zigbee shield to work with my ODROID N2+ using the UART pins (same gpio header as rpi).

Something new here? Same idea, but want to be sure it worked, before buying the odroid. Thanks.
