In the last post I described my new Filtrete 3M-50 thermostat and my data collection using a script from a wiki. I wanted an easy way to get values for datapoints on the graphs and have been looking for a use for javascriptRRD since discovering it a year or more ago.

I ended up having to modify the library slightly to get it to pass the yaxes option on to flot. My source is over on github.

You can see the real time data over here.
