From what I can see, homematic is a networked home automation server.  Being unable to comprehend German I can't glean much from their sales material, but they seem to use some kind of home-brew comms protocol

I'd suggest setting tcpdump to watch your packets and see what data is being exchanged.  It may well be that you're dealing with a fail-and-die protocol and not properly handling its failure response.

It might be considered overkill, but when I'm first building a networked process I log the hell out of everything, from raw line messages to the parsing and processing steps.  It helps, believe me.  If you give individual messages unique ID numbers, and make sure to print iteration numbers on loops, you can easily highlight where it's going wrong, or highlight adverse behaviour patterns.

Anyway, just my two cents.
