Limiting "requested current" to 16A

[krenlund]

I have a 11 kW go-e Charger installed with 16A breakers. However, with MQTT the "requested current" slider in HA goes all the way up to 32A.

What's the best way to limit current selection to 16 amps on a dashboard? I could probably work around this by creating a helper in HA, but are there other, better, more correct methods?

It's hardcoded at the moment: https://github.com/syssi/homeassistant-goecharger-mqtt/blob/main/custom_components/goecharger_mqtt/definitions/number.py#L33-L44

You could patch the file locally. On the long run a config setting is missing here or some auto-detection would be nice.

Your understanding is correct. If you use HACS your manual change will be overwritten on every update.

[krenlund]

Yeah, I just need to remember that after next update. Should be pretty obvious though when the slider range changes.

Did you try to change to slider to 32A (just for fun?). I guess it will be reduced to 16A by the Go-e charger firmware (in best case!).

[krenlund]

Yeah, I tried that by accident! It did indeed allow a higher current and the charger started pulling more juice from the grid! Didn't want to blow any fuses so I quickly turned it down. Also in the go-e mobile app the current was indicated higher than is possible to set with the app. So either there is no fail safe in the charger firmware or I have wrong settings somewhere 🤔 This is quite worrying if you think about it.

Uuuh. That's nasty. Good to know.
