We are ready to release a new app for the ThingSpeak Platform! The new app is called TweetControl – this app listens to Twitter for hashtags (#awesome) and allows you to control anything that you can imagine. TweetControl is a mash up of ”The Internet of Things” and social networking. We were inspired by an early ioBridge project created by Matt Morey in July 2009 that used Twitter for home automation. Matt could control lights or turn on his furnace using Twitter. Now that Twitter has a Streaming API, we were able to build a scalable service to control anything in real-time via a social network.
Imagine an “Easy Button” for Twitter. All you have to is Tweet a hashtag from your Twitter account to control anything that has a web service API. The applications for TweetControl are endless, and we are excited to see what you come up with. The documentation for TweetControl is available on the ThingSpeak Community site to help you get started.

Looks quite similar to what the WS4D folk (www.ws4d.org) already presented at the Embedded World in Nürnberg/Germany two years ago. There is even an online demo on the WS4D website to open and close a window via Twitter. It seems to be down currently
. But sure will be fixed soon
