ODB2 dongles to integrate into openHAB

There was some time ago some threads on “Connected Cars” and stuff.
I’m wondering, if anyone has managed to integrate data from ODB II dongles into openHAB?

I’m thinking of placing some ESP8266/ESP32 in the garage (or the car, if they’re not too energy-hungry) and reading some Bluetooth ODB2 - like EM327-based - and MQTTing the interesting data into openHAB. But perhaps there’s another simpler solution already in place or someone can point me to a good tutorial?

My primary use case is to read-out the SoC of my EV in real time, so I can use it to trigger charging it accordingly.
