Need help to setup RFXtrx. No devices are added

Configuration
1

I’m trying to add RFXtrx remote devices (IMPULS and later Somfy). These are working in Domoticz.
I can’t get this integration to work in HA. Also not with the manual of the RFXrtx integartion. Maybe it is to complicated for me (I’m Dutch).

I’ve added RFXTRX (RFXCOM RFXtrx) integration:

  • Select: Serial
  • Select device: /dev/ttyUSB0 - RFXtrx433 - RFXtrx433, s/n: A13UQUT - RFXCOM

Integration is added with:

  • Automated adding enabled

  • Protocols: ac, arc, lighting4, x10

  • Enabled Debug logging in UI

  • added also in configuration.yaml lines (don’t know if this part is needed):

logger:
  default: warning
  logs:
    homeassistant.components.rfxtrx: debug
    RFXtrx: debug
  • Restart Home Assistant

After restart an doning nothing i see the following lines in Logging ‘Home Assistant Core’:

Don’t know what this means. Is the integration working?

After pressing 2 times On and Off buttons (power switch goes 2 times On/Off) of the IMPULS remote controller nothing happens in HA. Also there is no extra logging.
I’m lost.

Before I used this RFXcom succesfully in Domoticz (on the same Raspberry PI).
For example I used the following setting in Domoticz to add:

  • Switch ype: On/Off
  • Type: Impuls
  • House Code: K
  • Unit Code: 13

Hope someone can give me an explanation to add (manually/automatic) these devices.
I’ve also 7 Somfy blinds to add (with the Somfy integration or RFXrtx? like in Domoticz).

Finally I figured it out myself. Did cost me al lot of time and frustration that no one had the answer. I’m replying with the answer so maybe someone else can use it.

Needed for my IMPULS switches codes. Like I said:

  • Switch ype: On/Off
  • Type: Impuls
  • House Code: K
  • Unit Code: 13

Help from sourced:

0x05: ‘IMPULS’
0x4B: ‘K’

Came also cross this site:

command should be:
generateId.py -t type -s subtype -p parameters
to generate a code for a Lighting1 type device using ARC subtype, set to housecode A unit code 3

python generateId.py -t Lighting1 -s IMPULS -p K,13
gives
071005004B0130000

This was not right!

id = ‘0710’ + TYPES[subType] + ‘00’ + HOUSECODES[args[0]] + ‘0’ + args[1] + ‘00’ + ‘00’

0 is not needed and number 13 to HEX:
K = 4B and 13 =0D so the correct code is:
071005004B0D0000

Switches are working know.

Also the Somfy blinds are added as RFY:
071a0000[id][unit_code]
