Great design
Great design; the json configuration idea is genius. No in app ability to mess with URL or API keys or any other settings. I love your work! Thank you!
Great app
This is a nice app. It would be even better if it was updated for iOS 7 design and also maybe have some tabbed interface in case we need to separate buttons in sections, and perhaps add more controls and ability to get feedback from http request (say you switch fan on, and of there's error, then it would stay as off)
