And TPMS. And key-fob remote lock/unlock. And BTLE for BYO music / calls.

This is the one big thing that has me leaning towards "used, 2015 or older" for my next car. With an EV, you really do want a way to specify how much power / when should be used for charging though; some "discounted" electric utility plans require being able to shed / schedule big loads on demand, too.

If this vehicle doesn't have any screen, you need to use a phone or similar to configure all this. Yes, schedule data can be done over BTLE, but something big like an OTA update can not be (at least, practically).

There's also a lot of value (for some people) in being able to change/monitor charge capacity from distances further away than what BTLE would support.

If the modem could be toggled and there was a USB port for software updates, I'd be _thrilled_.

I've a petrol car so I don't really know, but what's stopping the power/timing controls from being buttons on the charger wall unit? Even a local network app I'd have no issue with, but I really don't want my car or charging unit on the internet.

Yep, this can absolutely be done. Home wall chargers are just a fancy switch[1], you just need a way to enable/disable it. Could be a feature of the charger, but in the worst case you could add your own secondary contactor that removes power from the entire charger when you don't want the car to be charging.

[1]: They also have control pins to tell the car the maximum amperage they're allowed to draw, but that's not relevant to the feature of "disable the charger when I don't want it charging"

The car makes all the decisions about how much power to draw and when to do it. Excluding the DC super/fast chargers, the hardware on the wall is pretty "dumb".

It's been pointed out elsewhere, but remote notifications are useful so you know it's time to get out of the public charger and let somebody else in (or to go back out and check on why it's suddenly stopped charging)
