Hi,

I’m wondering if anyone has built BLE proximity detection, maybe using ESP32 boards for Homey?

I would want to know if certain devices (phones/smartwatches of my family) enter or exit a certain area (room or part of a room). Or if my car is at home. I know there is proximity detection for Homey but that won’t allow me to detect if a person enters or leaves a room, just if they’re close to my Homey.

Thanks,  
Paul

There’s the beacon app, but not sure it’s accurate enough to detect which room you are in.

This app possibly can do that:

>
> Make personalised flows with ESPresense

Right, that relies on the BLE of Homey which is not precise enough to determine presence in a different room than the Homey is in. Thanks for your response though!

Nice, I hadn’t found that one! Looks like the exact app I was looking for 😀

Thanks Peter!
