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 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 my fragile on these wall connectors, I’ve had a lot of trouble keeping it connected to my home network over the years.

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.

OTOH it would be super cool if we normalized wiring light sockets, outlets, and wall switches with low-voltage ethernet cable and had a simple way for mass-produced lightbulbs to plug into a wired network.

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

Funnily enough, I used to! (I even contributed a few PRs). However with my new home battery I need more granular control to do some tariff arbitrage that EVCC didn't really support. Great project though!

>SET THE TIMER ON THE CAR DIRECTLY!

This would open up a lot of issues to get away with not paying and charging for free.

Your comment makes no sense. The tesla wall connector is a home charging port you install in your garage.

I knew this is about wall charger at home but I assumed ‘time of use billing’ was some kind of billing system for the charger that’s implemented.

some people have variable electrical tariffs, so electrical use in the middle of the night is usually much much cheaper than the middle of the day.

That's done on the property's electricity smart meter.

It also fits the broader theme here: too much important behavior seems to live in the "application layer" of the charger, while the more durable source of truth is elsewhere.

I have a Volvo. Twice a year when DST changes, the schedule is afterwards one hour off. Been this for 3 years now.
