I've run something similar for 5 years, using https://www.smartevse.nl/ as the brains. The main advantages over commercial EVSE's in my case were that I could loadbalance charging the car with the electricity demands of the house, and that I could have the EVSE itself inside, so that there's no 240V current on any circuit from the breaker box indoors towards the car when there's no car present.

I do intend to add a second sometime, so that I can put the EVSE in my home automation UI as well; the version 2 of smartevse that I use does not have a network connection, but it can be connected to be controlled by a version 3 that does.
