  • 10 * X = Y, where this is X rather than Y.

    If you prefer, they might have said 0.1x as expensive.

  • This is a GREAT article, thank you for sharing!

    Also, learning about SparkFun's data service is very helpful, and that PID is terrific! I wonder if I could build one...

    Regarding the graphs, it would be interesting to get one of the local weather on those days overlaid on those graphs, at least the pre-PID ones. At a minimum, it would help your hacker space figure out how to save some energy and figure out how poorly the insulation is, since undoubtedly the internal air temperature had been modified using heating/cooling - which also corresponds to the highest energy usage costs of each day.

    Kudos for an excellent project and write-up!

    Cheers, Robert~
