Im looking for a way to see when someone enters/exits a door way (door is unlikely to be opened/closed)

I did a little poking around and found a 'dual beam' sensor, which is kind of what i want, but they are mostly bulky.

Ideally what would be nice is something i could put in to the trim of the door and potentially hook up to the power where the light switch is (might be mess so not opposed to a battery solution) but basically I want it to act like a garage door trip sensor.

The idea is that i'd like to turn the light on/off when you enter/leave the room and I want it to be responsive to the action of entering/exiting the door and not so much movement based.

I feel like there should be some sort of device thats like 1/2 inch in diamter that i could just drill a hole on both sides of the door jam and hell, even on the door itself which could in a perfect situation detect when the door is shut but also when someone enters/exits

the trim is nicely painted so I'd hate to have to pop it off, but that could be done if really needed

something like this in size/style

only ir/laser based. I cant find out for sure, but i think this is pressure based.

im planning on doing this with a discansce sensor from 'mysensors',
(https://www.mysensors.org/build/distance )
and then modify the code so it just sends those two signals to domoticz:

im planning on mounting the sensor above the door,
when it sees something coming closer --> someone entering,
when it sees something going further away --> someone leaving

ugh, im angry at mysensors.. according to the tutorials they make it seem like no big deal. but i attempted to make a very stupid temp sensor and i couldnt get it to work and it seems to boil down to a power issue, but i'd have to do something with external power to the radio and it just seemed like a pain with no real directions.

i did find a few zwave boards that are basically arudinos with a zwave chip/library built in to it. all pretty new and barely released... but neat none the less

and i've moved to beaglebones which i've gotten working but need to do a lot more coding to get that functioning well, and its really only good for a centralized controller for multiple sensors/functions... which... i'd like to do for controlling the garage door... its on the list
