The original idea was to create an automated reminder system that made use of the Wunderbar platform to monitor data. Eventually, we settled on solving a problem that many of us have on a daily basis: needing to know when our warm bottle of beer is cold enough to drink, as soon as possible!
We used the Wunderbar RESTful API to receive the sensor data, and Twilio API to send a text message to the user once the beer has reached below a certain temperature. Script written in node.js.
This could be extended to be a persistent monitoring service, having the node.js app run from an Intel Edison.
