A thought experiment. 5 known people and 1 pet in a room. 1 living being leaves the room. IR door sensor in place. What information do we want about the new situation? And what sensors would we need to gather it?....

@wallyllama Are you talking about all the way down to the system knowing who each of those people are?

I dont know. I guess Im wondering what you want from this. Do you care about pets vs humans? Adults vs children? General person count only? If the goal is to not shut the lights off on people then the last one is good enough.

I have recieved 2 amg8832 chips for experimentation after some delays because of import rules. The labeling on the bagggie says they need to be mounted within 108 hours of opening the bag. I would recommend getting a breakout board and not raw chips.
I'll post in the appropriate category any additional progress.

@wallyllama If I am looking at the information on these, these could see the direction a person is moving correct? If so, that would be a way to count people entering or leaving a room.

@wallyllama After watching this video this looks even more interesting.

I've been thinking of them as low resolution cameras that can see in the dark, but there may be more clever ways to think of it that I havent come across, but any computer vision algorithm would work. Motion detection for sure.
I have a fairly large living room with a high ceiling, if I mount one in the center, i should cover most of the room, I estimate a person would be about 1 pixel at the floor. The coverage is a pyramid so at the edges height is zero. Corner mounting like the video shows would probably fix that.
I think these work work better than my idea for a giant capacitive touch screen.

@matt-shepherd Something I hadn't thought of. Nice idea. I do have an Amazon Echo in my living room. My only question on that is have they figured out a way to sparate 2 Amazon devices like an Echo in one room and a Dot in another room to know what room a sound came from? Last I checked, that was not possible.
I was looking into it a bit for other automation stuff like turning on a light in a room. For example, when I am in the living room and I say "turn the overhead light on", it turns on the living room overhead light. When I go into the office, where now I am being heard by the Dot, and I say the same phrase, it should turn the office overhead light on. From the reading that I have done, you can't use them that way, but it should be possible somehow.
@dbemowsk this can be crudely done via routine feature on amazon alexa, what it offers is that you can rename any IOT device state (ON or OFF) with any name, so like in your example, living room lights you can just say Alexa "living room overheads" and it will turn the living room overhead lights, similarly for office you can say "Alexa; "office overheads" and it will switch on the office overhead lights. Ofcouse you have to have a different phrase for OFF state, but you get the idea. But yes the same phrase for all rooms and letting alexa sense which room r u in, and acting accordingly is actual smart home. I would keep searching if I can find n build somethig like that.

@sam9s what you are describing, while a nice way to control things, has the same basic flaw as a PIR device. You have to tell it you are there. The PIR(alexa) knows what room it is in, but you have to signal it some how. Alexa is signaled by a voice command, PIR by motion, but if you are quietly reading a book both of them forget you are there. Alternatively you can have them assume you are there for a set amount of time after the signal, or until they get an off signal.
The trick is to get them to detect you without actively addressing them. If Alexa can detect breathing, or heat or CO2, etc, then it would solve the problem.
you can combine alexa with door sensors. If alexa is triggered and no one has left the room then someone is still here. That is the idea that @dbemowsk pointed out earlier in the thread.

If you enter a room and do not say anything, then Alexa has no way of identifying WHO you are. Even if the echo could detect breathing, heat, or CO2, you are back to knowing that someone is there, but not who.
