I included documentation that explains what progress I've made on this. I've tried PIR sensors, and also IR Diode Emitter / Receiver pairs. I find the RF detector the best.

You'll see that I was forced to use two different walls and got around this by putting the sensor at a 90 degree angle in one wall via a drilled hole in a project box. It's somewhat laborious to wire these, as you are putting two outlets in, but it works 100% when installed. More details in the repo.
