You may have heard about “Internet Of Things”, platforms mixing hardware and software projects to publish and share data accross the web. The idea is to have some hardware collecting data, and publishing it on a website. One successful example, open source & free, is ThingSpeak, used here in this post.
So, Jaluino Bee is cheap (~$10 if you build your kit yourself) and that was one main goal while designing it. A reason is the cheaper it is, the more you can put Bees as things in the internet. This is the idea here: collecting electrical consumption from a power device and publish it on ThingSpeak.
