We've made a prototype for an Arduino version of our product TellStick, this makes it easy to control socket receiver such as Nexa, Proove, Home Easy, CoCo, Intertechno etc from Arduino.
We would like to know your opinion and interest about it, and depending on your feedback we might make a shield available for purchase.
