Earlier quoted context omitted.

You can bypass vehicle restrictions. You could potentially then use it for J1772-compatible EVs (like a Chevy Bolt or Nissan Leaf) Or just for the spirit of actually owning the shit you pay for.

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.

I use my Gen 1 Tesla Wall Connectors to charge my NACS-native Lucid Gravity.

I hate the gen 3 wall connector. It creates a wifi access point in your garage that you cannot turn off: TeslaWallConnector_ some people were able to downgrade their firmware to a version that didn't do that, but i guess this article shows telsa got rid of that ability. I would love to be able to hack any firmware to disable that. I also read that a connected tesla car can force an over-the-air firmware update maybe…

Thank you. This information is not listed anywhere and I am currently getting quotes for solar panel build.

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.

Eh, that’s a bad generalization. defense in depth is a thing and there are many cases where you’d want to protect against attackers with physical access

Why would I want to hack the bootloader for a wall charger? Asking for a friend

What vehicle restrictions? This is for the Tesla home charger, not Superchargers.

Arguably it’s a crack. A good one, though.

The SSID stops broadcasting after the unit is commissioned, unless you're using power sharing between multiple units. In that case the SSID is used for the units to communicate.

by commissioned you mean "connect it to your home wifi and let it talk to tesla"? (i won't do that)

because it hasn't gone away after configuring the setup stuff (amps, etc)

And make sure the firmware is up to date. Mine is at 26.2.2.
