Hyperion is an open source ambient light implementation controlled primarily by an Raspberry Pi. The main features of Hyperion are:
1. Low CPU load. For a led string of 50 leds the CPU usage will typically be below 2% on a non-overclocked Pi.
2. Json interface which allows easy integration into scripts.
3. A command line utility allows easy testing and configuration of the color transforms (Transformation settings are not preserved over a restart at the moment...).
4. Priority channels are not coupled to a specific led data provider which means that a provider can post led data and leave without the need to maintain a connection to Hyperion. ...
