after doing some experimental plaster trials yesterday (hard-work) 'was thinking about how to run the cable for the sensor-switches for our various doors (single & twin-door french-windows) and door-less door-ways (as it were) ... fitting reed-switches for the doors was what I'd intended, linked-back to digital inputs of convenient modules, but got to thinking about putting a PIR sensor immediately above the doorway, perhaps with a short tube over the sensor, to limit its field of view, instead-of or as-well, to better sense comings & goings ... hmmm, would it work (with Cortex) ?
not sure about reed-switches ... they say nothing about how far open a door is, or what it's doing, whether it's closed-fast & locked, or not ...
