Only able to read data not able to change

[26miller]

I am trying to get this working but somehow get stuck. I have installed this with ESPhome dashboard in homeassistent. Once installed and all proper values configured I was able to pair the bluetooth key with my car. After completing this I can see sensors update with actual data. But as soon as I try to change charging amps or any operation this action times out.

I am able to change these charging amps with my ios Tesla app and I also tried the suggested reset of tesla.

Can anybody point me in the right direction to get this running.
