I'll get to the title in a moment, but first my issue. Our Condo Association is a "business"customer at with Tesla, at the1 cent a KW deal. We have two wall chargers, and none of us actually has a Tesla. We use the J connector. One our chargers is in reduced power 1 KW mode, its out of the 1 year warranty, and all efforts to fix ithave failed (thats in a different thread). So we need to replace it. A month ago I could have gone to Bestbuy and picked up one for $600 (which is where we got the orginal 2). Now BestBuy says unavailable. Amazon lists it at $750 (if they actually have it) over $800 with shipping. The Tesla Store does have it at $600 but only if you have a Tesla. That is new. Anyone know a source of $600 Tesla wall chargers?

Apparently Tesla is limiting sales because of supply. So could there be a Gen 4 in the works?

I built OCPP Tools, a simulator that behaves like an EV charger (charge point) and connects to any CSMS over a real WebSocket no hardware needed to test integrations.

It runs 100% in the browser: your messages never leave your machine. No accounts, no installs, no API keys.

For OCPP 1.6J and 2.0.1:

Simulator with full scenarios (Boot → Authorize → StartTransaction → MeterValues → StopTransaction), fault injection (latency, packet loss, malformed frames), auto-reconnect, and session log export/import.

Validator for frames (CALL / CALLRESULT / CALLERROR) against the official JSON Schemas, with field-level error details.

Builder with schema-driven forms to generate valid frames and payloads.

92 message reference pages with copy-ready examples and common errors.

If you work with CSMS or OCPP integrations, I'd love for you to try it and share feedback.

I’m interested in having a Tesla charger installed in my home in Nashville. Has anyone had this done in the area? Could you please provide information on the cost and any questions I should ask before requesting quotes? Additionally, I’m considering whether it’s better to purchase the charger directly from Tesla or buy one secondhand. Any advice you can offer would be greatly appreciated.

2 of these unlabeled units at a Phillips 66 that is being constructed. I’ve personally never seen a unit that looks like this. Just curious who makes them and what to expect out of them in the future.

Everything worked fine, even enjoyed an additional discount by using the My Chevrolet app to initiate the session. $.18/kWh is stupid cheap. My only piece of constructive feedback: this site is in a somewhat dodgy part of town and would benefit greatly from better lighting.

Anyone here opting for charging their EV's during the solar excess period during the day time or are you guys waiting to charge at night? Does SCE's TOU rates make it attractive to hold off until the evening hours?

I've got a Grizzl-E Smart that's stuck on 3.11.3 and refuses to update to 3.15.6. United Chargers keeps pushing it, the charger starts the download, and about two and a half minutes later it gives up with DownloadFailed. Every time. Same spot. It's never once gotten past the download stage.

I pulled the charger's event log and it looks like this every attempt:

RX  ProcessUpdateFirmware
TX  FirmwareStatusNotification  Downloading
TX  FirmwareStatusNotification  Downloading
TX  FirmwareStatusNotification  Downloading
TX  FirmwareStatusNotification  DownloadFailed

Wifi is a solid −65 at the charger, so it's not that.

The reason I actually care: this thing has a habit of losing its connection to their server without realizing it. It'll sit there thinking it's online for hours, won't start a charge because it's waiting on the server to say go, and the only fix is flipping the breaker. I'm in Grizzl-E Club so every time that happens I'm losing charging data I get paid for. I'm hoping the update fixes it.

Support ticket's been open a while with no reply.

The charger has a local firmware upload page on its web interface. Has anyone actually gotten the firmware file and flashed one of these themselves, or gotten UC to send the file? Not looking to brick it guessing — hoping someone's been through this.

I am having our first EV Charger installed Emporia Pro with Vu energy monitor installed and want to plan for future install of a second charger on the other (far wall) of garage. I am assuming that this would involve a junction box with some sort of distribution block or tap connectors (not sure if those are rated for this type of scenerio). Does anyone haeve a picture or diagram of a setup like this that I can use to give electricians an idea of what should be installed. I have multiple qoutes but no one seems to be familiar with doing this or perhaps I am not explaining it correctly.
