This is a great improvement to my EV charging automation. I installed a wallbox, and extended the range of charging power from 1.4-2.4 kW to 1.4-11kW. This does not seem like a complicated thing, but if you have a wallbox yourselves, you know that 3-phase wallboxes start at 4.5kW. And 1 phase wallboxes end on 3.8kW. How did I manage to get control through the whole range? Check it out!
