Electricity usage as recorded by the Wattson

and as recorded and graphed on pachube for a period of a month

This is our house electricity usage - read in realtime by Ruby software running on a Mac Mini (home grown software as such) through the Wattsons USB port.

As you can see from the graphs the software has been reasonably stable for the last month, the next step for this part of the home monitoring system is to use this to display current energy usage in a few places around the house to keep us all aware of how much electricity we are using - as this seems to be the best, and most sensible way of reducing our total electricity usage.

I now need to get the same kind of information on the usage of gas, as most of our heating is based on gas - and as we have a very old gas meter with rotating digits this is not terribly easy...
