doesn’t seem like it needs to increase the electric usage by that much, you only need a RasberryPi or equivalent to run the server, and you control everything with your phone… the outlets and solenoids shouldn’t need much power to do their thing. I saw earlier today how many options for EVs are available in South America (anywhere outside the US imperial core, actually) and it was a bit shocking. The conversion to EV business seems like a great idea - especially if they can standardize replacement parts that would be amazing.
