For the past few days I ahve been trying to set up the Tesla Fleet integration so I can pull by Powerwalls and EV into HA.
I have
- Created a Tesla Account
- Created an Application with Authorization Code and Machine-to-Machine set
- Generated a Public/Private Key Pair
However when I try to setup the Tesla Fleet integration in HA it opens the Tesla autnetication site then throws an error ( Tesla Auth ):
# Something went wrong. Try again later
Client authentication failed. Please verify the credential provided for client authentication is valid.
Reference ID: b82d60d6-07e1-4e61-ae31-a024dca61975
I've been around the loop a few times, setting up additional applications with the same outcome.
My friendly AI says there's a bug that means the Tesla process is setting grant-type to
client-credentials, authorization-code
and suggests this is wrong, but not how to fix it.
Any advice would be hugely appreciated.
Additional info:
- I have a UK Tesla account.
- I am not being prompted for my credentials before getting the error
