Possibility of a New Authentication Method?

[rstad944]

I noticed in the latest Tesla Android app under Settings that there is an option to "Pair Phone to Powerwall" which requires a toggle of the PW switch.

Has anyone been able to exploit this option to pair a local controller (e.g. Raspberry Pi) to the TEG via a LAN connection?

I am especially wondering if the Powerwall mode (backup, self powered) could once again be controlled locally without using the owner-api.teslamotors.com endpoint. This local control capability had been essentially removed when the PW firmware was updated from 1.49 to 1.50.

Also keen to hear more about this! Just tried implementing a POST to /api/operation in tesla_powerwall python library repository, and it wasn't till I ran an integration test that I happened upon an access denied error, e.g.:

tesla_powerwall.error.AccessDeniedError: Access denied for resource /api/operation: Unable to POST to resource: User does not have adequate access rights

Would be fantastic to modify backup percentage via api 🙏

Agree. This does sound very interesting. I'll leave this issue open until we can find a solution.

I was able to make API calls to my gateway by grabbing the bearer token after logging in to the local web app (as "customer"). It only lasts for a few hours but it allows me to make calls to the /vitals endpoint.

@patniemeyer Just double checking if you're still able to replicate this?

I tested using a bearer token and am still seeing a 404 for /api/devices/vitals.

EDIT: Oh perhaps you're referring to a version before 23.44.0.

@longzheng as we can see it is REDACTED.

Maybe we can implement a Authentication to the Code?
