Hi.
I want to make a simple and cost efficiant way to have an montly overview of kwh for usage of underfloor heatingcables.
How much kW the heatingcable is delivering is easily measured with instruments and the measured kW is accurate enough for most uses.
My plan is to count the time while the relay for the heating cable is active, and multiply this time with the cables kW for every hour of active relay.
Then i want to extract the kWh for each previous month, and add it to a trend.
This will when time goes by show the last 2 years of heating cable kWh usage.
Does anybody have a script with something similar that can help me on my way?
