Unable to Control Variable Charging Amps

[pwhitea]

Is there an existing issue for this?

• I have searched both the existing open issues & recently closed issues and did not find a duplicate of this issue.

I have read about the Fleet API and understand I may need to use it

• I understand issues relating to read only commands will be auto closed if not using the Fleet API.

Version of the Tesla component

V3.24.1

Version of the Tesla car software

2024.32.3

Model

Model 3

Current Behavior

I am trying to control charging amps on my M3. My Tesla wall connector shares a 32A circuit with other devices (washing machine) currently. I want to be able to vary the charging to take advantage of the 32A when other devices not in use. I have been trying to use the following for this and it does not work - see debug log.

data:
email: xxxxxxxx.com
command: CHARGING_AMPS
parameters:
path_vars:
vehicle_id: "XXXXX"
wake_if_asleep: true
charging_amps: '10'
action: tesla_custom.api

I am finding that a wake up call does work OK, so there is nothing fundamentally wrong with setup, the following call wakes up the vehicle just fine.

data:
email: xxxxxxxx.com
command: WAKE_UP
parameters:
path_vars:
vehicle_id: "XXXXXXX"
wake_if_asleep: true
action: tesla_custom.api

Expected Behavior

Expecting that the following will change the charging amps on vehicle when executed

data:
email: xxxxxxxx.com
command: CHARGING_AMPS
parameters:
path_vars:
vehicle_id: "XXXXX"
wake_if_asleep: true
charging_amps: '10'
action: tesla_custom.api

Testing this in the Developer Tools results in following error, plus logs -

Failed to perform the action tesla_custom.api. Unknown error

Anything else?

No response

[wesback]

I am seeing the same behavior, however I am also no longer able to change the amps using my mobile app so I am wondering if the problem goes deeper that just the integration.

[skipishere]

Is this still a problem?

[TomVL]

Is this still a problem?

yes it is. I'm also unable to change the amps and even the max battery level percentage...

[zlymeda]

see teslamotors/vehicle-command#287 (comment)

[garethcook]

I do this, been working fine for a very long time

- data: value: "0" target: entity_id: number.tesla_charging_amps action: number.set_value

[jambees]

I have this same issue. I've tried using the following in Developer Tools - Actions and after a delay it returns an error.

action: number.set_value target: entity_id: number.tesla_charging_amps data: value: "6"

The error reported in the UI is "Failed to perform the action number.set_value. Unknown error"

In system logs it seems there are two log errors for the time I attempted the service call:
