We're building a new house at the moment so I'm looking into various flavors of home automation right now. And even though many people seem to go with Philips HUE-based solutions, I've decided on using KNX instead. There are both advantages and disadvantages but that's an entirely different post.

Obviously I want to be able to add my own components to the setup – both as actuators (i.e. things that are controlled by automation/switches, like lights, relays, motors) and as sensors (i.e. inputs that can trigger stuff, like switches, light sensors, motion sensors, …).

Since my weapon of choice at the moment is NXP's 32 bit ARM LPC11U00 series, the job at hand is as follows:

Connect an LPC11U68 to a KNX bus and observe and send data objects.
