node-hue-api VS room-assistant

If OP has Philips hue bulbs, the Pi can interface with the bridge over LAN with nodejs modules like this

Also, I am using the bluetooth on the Pi to drive Room Assistant, to tell which room I'm in and automatically switch on the audio in that room when I am in that room, and switch it off when I leave. It also has support for the grid-eye sensor which looks like the flir sensor you useThere's also a similar project for ESP32 called ESPresence.

Check out Room Assistant. I have 9 RaspberryPi Zeros set up around my house and these do a great job tracking which rooms our cats are in, provided that we put a tiny BLE dongle on their collar.

Earlier I had six raspberry pi's spread around the house to try out new things (e.g. room level presence detection - which did not work well despite weeks of tuning - and as snapcast clients). But it became a pita to keep watch over so many independent systems, updating them, remembering the IP, passwords, forgetting what I have installed last time, etc. This is what I like with the whole docker thing: fire up a container, tweak it, and then if it is not used delete it again without affecting the other services.

There's a project called "room-assistant", however you'd need to have multiple Raspberry Pis running it in various locations...

You can try room-assistant. It takes your Bluetooth devices and calculates distance, works quite nice in my environment for in room detection.

I've been playing around with room assistant. https://www.room-assistant.io/
