Nice job guys. Thanks.
To reinforce what Ray suggests above — future improvements would be to allow us to download all data points instead of just the ones displayed on the graph. For instance, if I am interested in the details of my temperature logging over the week, I need to see the temperature data for every minute of the week. Yes, 10,000 pts but that is the detail needed.
Also, perhaps a way to offload the data is to have the option of a trigger setup so data can me emailed out every day/week as the user desires. One could even setup a way to capture the emails into a separate folder or dropbox share for later analysis.
