Feature request: Checkmk compatibility

[mschlenker]

Hi Mario,

I worked for Watterott in recent projects and currently work as technical writer for @tribe29. To be able to include the Watterott CO2 traffic lights in Checkmk https://github.com/tribe29/checkmk monitoring, the easiest way would be listening at port 6556 and spill out collected data in the Checkmk plain text format. In case I did this implementation including documentation, would you include it in your repository? Or would you prefer me to fork it?

Thx! Mattias
