Tibber - Set SoC of an "non integrated" EV in Home Assistant

I use Tibber as power company/buy/sell electricity from.
I also have an MG4 EV. The MG4 does not have an “Tibber Integration”, which means that every time I want to charge my MG4 at home, with my “Tibber Integrated” EV charger (Easee), I need to manually enter the SoC (state of charge) of the MG4 into the Tibber app.

I would much rather have HA do that form me :smiley:

I can read relevant data from MG/SAIC using the integration;

And I have the Home Assistant Tibber Integration installed.

- Now, do we have any geniuses in here that can poke around in the Tibber API and find out if I can change the SoC of a specified EV (we have two).
