Please provide the full payload of your application trying to register your XMLRPC server to the HMIPServer. |

Hi,
these are the server and the client to register the server.
Server runs on: 192.168.0.50:8000
CCU runs on: 192.168.0.25:2010
Tried Port 2001 and also 2010. Both gave the same result.
According to wireshark, the server responds with an empyt XML-RPC response after registering it.
This is the wireshark trace:

Sorry, but please no email reply to github emails. Use the web browser to edit/add comments and don't answer via email to github emails because all your things end up unformatted in the ticket. And please use code tags for formatting code! |

Sorry, but perhaps you should have a look for other python related projects communicating via XMLRPC to a CCU/RaspberryMatic device like https://github.com/danielperna84/pydevccu from @danielperna84 since this can't be a general issue/bug within RaspberryMatic what you are describing here. And this here isn't a discussion fora where you seek for help in your development but only for reporting issues/bugs that need to be fixed in RaspberryMatic itself. However, if you want I can move over this ticket/issue to the discussion section and then other ppl could help you accordingly. |

Hi Jens, thanks for your time and looking into. |

Describe the issue you are experiencing
When registering an external XML-RPC Server (using INIT Method) the CCU should respond with a list Devices.
This doesn't happen, but instead in the log File it appears an error:
Error requesting method listDevices: <class 'TypeError'>:MyServer.listDevices() takes 1 positional argument but 2 were given Code: 1
An external triggerd "listDevices()" respondes with the expected behaviour.
