The final interface board (click for full size)

In our new house, we're installing KNX as the primary infrastructure for home automation.
And obviously, I want to connect the garage door to the home automation system. Both to be able to run automations whenever the door opens or closes and to be able to control it from other devices than the standard remote control.

My solution comprises the following components:

KNX bus → KNX I/O unit → interface board → UAP 1 → garage door opener → scary outside world

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.
