Autel charger issue

[marcsuard]

I am very satisfied with my Autel MaxiCharger AC and the overall integration works very well. Almost everything functions as expected.

However, I have one issue with the charging current adjustment. Whenever I try to change the maximum current, I receive the following error message :

PropertyConstraintViolationError: When chargingProfilePurpose = ChargingStationMaxProfile, chargingProfileKind SHALL NOT be Relative

Could you please let me know how I can solve this, or if this functionality is not yet supported with my setup?

Thank you very much for your support. I really appreciate the product — this is the only function I am missing.

Best regards,
Marc

@marcsuard Don't change the max current. This will work for you, just change the variables to what you have. I have an Autel and have automated it fully through HA and this integration.

conn_id: 1
custom_profile:
transactionId: "{{ states('sensor.charger_transaction_id') | int(0) }}"
chargingProfileId: 1
stackLevel: 2
chargingProfilePurpose: TxProfile
chargingProfileKind: Relative
chargingSchedule:
chargingRateUnit: W
chargingSchedulePeriod:
- startPeriod: 0
limit: "{{ min_evse_rate }}"

Can I ask what version of this integration you are using? I am currently on 0.7.0 because a couple more recent ones did not work.

I have made a blueprint of my automation. It has all the details about what I tested with. I also can't get past 0.7.0 so am running that.

Thank you very much for your support and for sharing your blueprint and experiences.
I followed your advice to use a TxProfile instead of changing the station max current, and it now works perfectly with my Autel charger. The automation runs smoothly and integrates very well with my setup.

I really appreciate the time you took to explain and provide examples – this was exactly the missing piece I needed. Thanks again for the great work and for making this integration so powerful!
