Source code
We use a website called Github to house most of our source code. You can build the Candle Controller from scratch if you prefer to do so.
The Candle controller is based on the Webthings Gateway, an open source smart home controller that was originally developed by Mozilla, and is now overseen by the Trellian company. We build on their wonderful work, but are not affiliated with them.
Additionally, we've created an overview other open source projects that we build on.
