Looking around for sparkfun IOT chart, I found that imp.guru can grab and plot data from sparkfun if you just hand over the public keys!

So I have imp.guru/f48 showing live data. NICE!

But I wanted to make charts with Input and Output temperatures together, I stumbled onto phant.io http://phant.io/graphing/google/2014/07/07/graphing-data/ where they describe how to use google charts to plot data.

I took a few hours and got charts! http://bobodyne.com/boiler

I'm pretty happy that I can look at the boiler, show other engineers what's going on and keep track of things.

I want to add temp sensors on zone #1 (Basement) and maybe an outside air temperature also.
