[rrd-users] Calculation that is a bit over my head.

[Jan Johansson]

Hello!

I have a data source that logs either 0 or 1.
This data point relates to the state of a relay that controls a 3kW water heater

I would like to be able to do dead reckoning of the power consumption of this heater for a given period of time.

But, I cannot figure out how to do this.

Any hints?
