Car/Bike protection using ESP32 or such

1

Has anyone thought about a way to use ESP32 etc for protecting cars/bikes against theft?
I am thinking of maybe

  • disc locks with ESP32 alerting
  • same for cable/chain locks (incl electric continuity check against the chain being broken, vibration/motion)
  • GPS location
  • posisbly bluetooth presence to allow usage (ala Monimoto)

All these could report locally on/in/near the vehicle via ESP32 or BT to a HA-like center (maybe running on a Rpi Pico) which in turn could be used to alert via Telegram etc and also to a HA instance?

That way only the center/controller needs to have a SIM (eSIM) connection, the other elements report to teh controller via BT or ESP32 or such?

The same controller could then maybe also be used as gateway for a camera system to upload video files recorded etc. ?

Has this been done?

The “controller” idea is flawed.
If your car is 10km away, how do you envision the ESP32 to talk to it? Lorawan handles long-distance, but is not reliable enough, afaik.

Apple already invented Airtags for this (and Google is coming)

No, that is exactly the point. The controller is hidden somewhere on the bike, and has 4G/3G/2G or such connectivity. Which allows things like the disc lock, the chain lock, the GPS tracker etc to not also need their own connectivity. So a local network that includes all optional devices that track, secure etc and the car/bike. The controller is then responsible for sending the alerts via a single connection.
