Hi,

I got it flashed but now I'm getting the following error in the logs. Compiled and uploaded with ESPHOME terminal

Okay, update. I thought I had a shortcut by just taking the BLE MAC from my phone.. Seems like that caused it. I used the tesla_ble_listener and it turned out to be a different MAC. I used that and boom! It recognized the ESP32 as a key.

But I wan't there yet, it wasn't working.. After literally doing esphome run tesla-ble-esp32-generic.yml a few times. It just started working!

NOTE: minimum amps is same as in the app, 5. (Using the trickle charger) NOTE: When pressing "pair" you don't get a popup on the Tesla screen, until you tap your key card!

So to re-iterate:

1. Install ESPHome CLI locally
2. Clone/download the project locally
3. Create secrets.yaml and put in your details. (Including a new api_encryption_key)
4. Go into the directory and run esphome run tesla-ble-esp32-generic.yml (Make sure your ESP32 is connected via USB to your PC)
5. Once it's done, it should boot up and start showing you logs.
6. In Home Assistant, go to Settings > Devices & Services > ESPHome > Tesla BLE device and click "Pair BLE key"
7. Tap your NFC card to your car's center console
8. Hit confirm on the screen

Success! @yoziru Thank you.

I've also had a few issues to get the pairing to work but seemed to finally do it this morning. I haven't repeatedly rebuilt it like you and, moreover, I've adopted it into my HA esphome add-on so I can easily update it - I've already done that too. I just tried pairing again this morning and I could now start charging and change the charge limit. The real test will be when I take the car away and then return home - will it still work?! Fingers crossed!

Update

Getting errors again. It's really intermitent. @yoziru any idea?

Just installed the new release and tested it. Worked great on first try, then exited the vehicle. Went of of range, got back in and then got the following errors and it didn't recover. Let me know if there's a specific scenario you'd like me to test.

I was having a similar issue as @TwilightDuck here after getting this built using a generic cheap, nasty esp32devkit board off aliexpress. I also didn't install espHome "standalone" - I put the yaml straight into ESPhome inside of Home Assistant and got it built that way.

I've noticed the following messages repeating in the log, even after pairing the key (and seeing "Unknown Key" in the Locks menu.

Plus whenever I would try to do something (wake, set charge amps, start/stop charging) I would get this:
