This tool was made because NEST only displays the last 10 days of energy usage in their app and webclient. For me this was a pretty big limitation, rendering the whole idea of getting a detailed overview useless. Based on how NEST interacts with their customers, I don't expect them to fix this problem any time soon. That's why I decided to make the tool myself.

The tool can be used with historical data that is available here:

https://myaccount.nest.com/mynestdata

Request an archive with all data and wait for it to be processed (this can take a long time). Then extract the data from the zip file and simply find the month that you'd like to check out. Then drag the "year"-"month"-summary json file on the site, and you will get the overview of that month.

Please note that all parsing is done on client-side. No reports are uploaded to a server!

Known issues:

• * (!) Currently the reported heating/cooling cycles are random and change with each request. This has been reported and I've no idea when they will address this. Feel free to bug NEST support about it yourself ;)
• * I'll continue updating this tool, once NEST fixes their reports
• * Tested with Chrome & Firefox only. No plans for all browsers support
