I'm working on an iPhone app which lets the user configure a set of colors and associate the colors with a temperature. Using the current temperature and the configurations, the app will calculate an appropriate color for the Philips Hue light bulbs.
The app currently uses a third party service to get the weather information but I plan to support the Thermodo device.
I'm currently looking for a few testers. If you are interested and have access to Philips Hue light bulbs, head over to http://c.4su.re/QCdK and sign up :-)
