I finally managed to publish a simple environment monitor I wrote couple of weeks ago.
It is now successfully running at three locations, utilising quite standard BigClown setup, Raspberry PI that runs simple Python script and finally my general purpose InfluxDB/Grafana server.

Feel free to improve etc.
this is pretty awesome job which has inspired us to start building on Grafana as well.
I have only one suggestion - it is better for future compatibility purposes to share your firmware as a copy of this skeleton: https://github.com/bigclownlabs/bc-core-module
Many thanks! P.
