Vailant Heating Unit Monitoring

Monitoring my Vailant Heating Unit with a Ebus-Coupler (esera) connected via USB to a Raspberry PI. Frst, I collected the data with vwmon (C-program based on ebusd) and loaded the data in a MySQL-DB.  I have plotted the collected data with chart.js.

In the meantime I am collecting the data with a FHEM-ebusd-Module and visualate the data with grafana.
