Hi,
I bought a homematic ccu3 which actually is a raspberry pi3 with a board on it which has separate power plug.
I’m changing the SD of this with a hassio one and I’m trying to install homematic ccu plugin in hassio and configure it.
Since there aren’t any examples of ccu3 I’m using this configuration from documentation:
rf_enable: true
wired_enable: false
hmip_enable: false
rf:
- type: CCU2
device: /dev/ttyAMA0
wired:
- serial: xy
key: abc
ip: 192.168.1.0
hmip:
- type: HMIP_CCU2
device: /dev/ttyUSB0
After I start it I get a lot of errors like:
2020-12-14 20:05:59,339 [ERROR] BidCosRpcDispatcher - Could not register BidCos-RF_java```

I also did the config.txt which wasn’t easy to do at all on the boot partition 
dtoverlay=pi3-miniuart-bt
The hardware output is this:

anyone managed to do this successfully?
Basically ccu3 is just a raspberry pi 3b+ with a board on it… photo attached.
