Daily consumption and costs of energy

This flow calculates and visualizes the consumption and costs of the current day. Data input is a MQTT device, in this case the WLAN ACM-ESP gasmeter interface. In node "consumption to cost" you can adjust the parameters for the calculation of costs.

let Z = 0.93; // Zustandszahl
let H = 11.3; //Brennwert kWh / Nm³
let c = 14.32; // Cent / kWh
