I have the same problem (V2C Trydan). The maximum current slider seems to be broken. I've seen a few changes in the last versions related to the number component, not sure if that might be related.

Are you on the latest HA version? If not you need to be on at least 2022.8. Otherwise try a reinstall of the integration ensuring you set the max current to match your charger specs.

Yes, i’m using the latest .8 version It’s a 32A charger. The slider is fixed at 32A, and when i change it, nothing happens, it just goes back to 32A.

@bananaslug123 it looks like your charger is isn't conforming to the ocpp standard. You'll need to log the actual messages and look at the response before the index error is thrown

See how you get on with the latest release
