Hello,
i have a KM200 installed to my heating system and i'm wondering if i could interface to that module via NodeRed.
When i search, i don't find any Buderus node, although i find 3 Bosch nodes...
Does anybody knows if one of these nodes match with the KM200?
already thanks!

It wouldnt be too difficult to create a contrib node for this (there are several libraries on [npmjs.com](http://npmjs.com))
however, this might work for you...

Run that and then just subscribe to the MQTT topics in node-red.
