| 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! |

| I hate the gen 3 wall connector. It creates a wifi access point in your garage that you cannot turn off: TeslaWallConnector_<unique-id>
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 through the charging cable or wifi, but I haven't verified that. |

| ▲ | m463 29 minutes ago | parent [-] | | by commissioned you mean "connect it to your home wifi and let it talk to tesla"? because it hasn't gone away after configuring it (amps, etc) | | |

| 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. |

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

| ▲ | m463 2 hours ago | parent | next [-] | | 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. | | |

| ▲ | akerl_ 2 hours ago | parent | prev [-] | | Can confirm. I've used an adapter to charge 2 different non-Tesla cars off my wall connector. |
