Over the Holidays I bought some Bluetooth LED Candles called PlayBulb. They come with an app but I wanted to control them via WiFI and integrate them with WIoTP and take advantage of Node-Red, Watson API and Twitter. E.g to reflect the mood of Tweets. Here the IBM DeveloperWork Recipe https://developer.ibm.com/recipes/tutorials/playbulb-candle-watson-iot-platform-using-watson-apis-and-twitter/
