Ever since I got my Nest all I've wanted is to be able to aggregate my energy usage over a long period of time to look for patterns and mainly appease my curiosity. Sure there are the monthly usage reports, and the web and device only goes back 10 days.
Does the API expose that data, or would I need to somehow calculate it myself? I'm not seeing on the API reference anything like 'is_running'. Or is there a chance a future "Nest Data API" is going to come out?
The Nest API only provides realtime data, not historical. Nest has an online community where they accept product suggestions for future enhancements.
