is it possible to determine the car that's connected?

[g-i-t-h-u-bb]

Is it possible to determine which car is connected to the charger? I know Tesla can simply see which car is connected at a supercharger. I would imagine the same is possible with other chargers. I have not found anything that points in that direction. The log also does not seem to contain it. But it would be a great feature!

kindest regards,

I've been strugling with the same problem. I believe there is no data communication between AC chargers and the car except some low voltage signals to determine the state of the car/charger. That's why your charger also doesn't know the SOC, unlike with DC chargers, where this is different.
I've seen looking for a way to determine which car is connected as well, the next step is to automatically with plug and charge switch between tags so the kWh get charged to the right tag. There was an issue in this post about getting the rfid tag, which could help you to determine the car connected (after you have scanned the tag). It shows that this feature was included in a beta release, but I haven't had a chance to see if this option made it to production release already.

for your question, I'm relying on the Audi connect app to determine which car is parked near the charger and is plugged in, this doesn't give a 100% succes rate, as it relies on the Audi connect integration, not ideal.

I use the resistance sensor for this purpose. For my both electric cars there is a fair difference. This is my code for the template sensor:

{% set resistance = states('sensor.alfen_car_pp_resistance_socket_1') | int(0) %}
{% if resistance > 32500 and resistance < 33500 %}Car 1{% elif resistance > 650 and resistance < 750 %}Car 2{% endif %}

I guess this can be closed, as there is no way to get a 100% solution for this.
