Great idea, Gustavo. Keen.io makes it easy to create, measure and visualize pretty much anything. I once used it with a Tessel to record ambient light and temperatures in a room to help optimize conditions for plant growth. The WiFi module on the Tessel 1, however, was pretty flaky, and I ended up abandoning the project after awhile and forgetting about it as a result. The trick for goal tracking will be to automate your script so you don’t need to think so much about using it — perhaps using a CI solution — and setting a periodic reminder to come back and revisit your goals on the Keen dashboard from time-to-time to help reinforce positive behaviors.
