A simple script to pull data from a vcontrold daemon and push it into a carbon instance.
Optolink adapter -> vcontrold -> vitographer -> carbon -> graphite -> grafana
scale(scale(summarize(scale(scale(scale(vitodens.performance, 0.01),1.82), 11000), '1d', 'avg'), 24), 0.00006335)
0.01-vitodens.performanceranges from 0 to 100% -> map to interval[0,1]1.82- factor I came up with to address the deviation between measured value and real value11000- 11kW (my gas heater's max power)- summarized average value per day (in Watt hours)
0.00006335- € per Watt, i.e. 6.335 cent per kWh
