Why use Tesla wall connector in a first place and not just the standard nema/dryer outlet with the Tesla cord/charger? It seems like people are overpaying for nothing.

I don't think there are any restrictions. I think j1772 might just work with an adapter (adapt from the nacs plug to the j1772 plug) I thought tesla even made a j1772 native wall connector.
There are some restrictions. I had the foolish idea of installing a Tesla charger at home to charge my Bolt. I’ve been unable to ever use it. The wall charger works fine with Teslas. My car and adapter charge fine at Tesla superchargers. But the home Tesla charger refuses to charge my Bolt. (Yes I disabled vehicle restrictions and tried all sorts of combinations of settings for weeks before giving up. Tesla support w…
This is the one I use https://ev-lectron.com/products/lectron-tesla-to-j1772-adapt...
Repeat after me: An owner voluntarily downgrading firmware to gain control of your hardware IS NOT A HACK. And if an adversary is doing this, then they have already breached yoir physical security.
It clearly seems people have different meanings to the word, then. For example, if I am able to gain root access to a WiFi access point I own, even though the vendor has tried to prevent it, then yes, I would call it a hack. To me, it doesn't matter why or who is doing the steps. In fact, I believe I have never before heard someone combine the meaning of the word to be related to the ownership of the device being hac…
Ownership implies authorization, and using the term "hacking" exclusively to refer to gaining unauthorized access to someone else's computer is a common usage that you must surely have encountered before.

> I thought tesla even made a j1772 native wall connector. At least a few years ago, they would openly recommend it for non-Teslas. I thought NACS brought some changes to Level 1 and 2 that aren't backwards compatible with J1772? I know there's an oddball voltage in there so you can put a NACS charger on a lamppost where J1772 would require a transformer; but I didn't think there were protocol issues too.
J1772 is 120V or 208-240V. Those are by far the most common voltages in the US. (208 is what you get when you take a US 3 phase system and connect to two phases - this is somewhat common and most people don't know or care that their apartment is wired like that). I have seen other voltages at industrial sites, but I wouldn't expect that in a lamppost.
J1227 would require a transformer, but NACS doesn't.
PSA: If your wall connector loses wifi, it'll just throw your charging schedules out the window and turn on/off sporadically. This is especially noteworthy if you have Time of Use billing :| SET THE TIMER ON THE CAR DIRECTLY!

While hacking is used to to refer to illicit activities, I do actually believe that the same activities can also be performed e.g. on your own devices, or with permission, and still be called hacking. So in my view, I do not believe legality is the defining term, but the actual things you do; oftentimes useful for illegal activities.
But I must assume there is a group of people who consider the term to be loaded with that exclusion, so I should take this into account.
However, to me "hacking your own devices" as a concept seems crystal clear, and is not a contradictory term.

I can do 48A @ 240V with my wall connector. It's also very convenient.
I do as well with a NEMA?
I've had both setups and whether the full amperage charger is worth it or not depends on your use case. If you're just going to plug it in overnight, it doesn't matter. It's about an hour's difference for a top up. If you're going to wait for your car to charge and unplug it because you share the charger or have to run an extension over a public sidewalk, then the faster speed is worth it.

I spent an hour yesterday getting the wall connector back on my wifi. Apparently last October when I added wifi 7 access points my network started working in WPA2/WPA3 mode and the wall connector wasn’t compatible with that. Ended up having to create a second SSID with WPA2 only support to get it back online. Supposedly the newest update fixes that, but I haven’t taken the time to test that out. But WiFi is shocking…
Does the tesla wall connector offer Ethernet? Honestly I feel like most devices that are not expected to move around should at least offer it as an option (exceptions being for things where it’s not feasible like smart bulbs, smart locks, etc). If anything it’ll remove congestion for things that can’t realistically be wired.
Too many problems to count:
- High voltage and low voltage wiring should generally be kept separated for safety reasons. Light sockets could probably be moved to low-voltage-only to power just LED bulbs but this wouldn't work for wall outlets which need to be 120-240V. Plus I like having the option to install 120V halogen bulbs wherever color rendering really matters!
- We'd also have to "normalize" having a separate network just for IoT stuff that only communicated in/out of its own LAN boundary via an actually-secure gateway with generic open protocols. (Pipe dream without government enforced standards similar to or piggy-backing on building codes)
- (Most) electricians notoriously suck at understanding low-voltage wiring.
- Probably more that I'm too lazy to think about but these two are already show stoppers for the next 10-30 years.

or, use Home Assistant to handle your charging schedules.
or even better, use EVCC https://github.com/evcc-io/evcc
