Feature Request: 11kw and 22kw mode option #44

Hi, I am using this nice piece of code since the beginning and I love it! As I changed now from 11kw to 22kw I miss the posibility to set the current value up to to 32A (16A is the max at the moment).

For the moment I change the code by myself every time. I think it would be a good solution to make it configable in the Integration sektion (11kw or 22kw).

What you think?

hm... as far as I know the Wallbox is set to 11 kW by default - and needs to be shipped in and needs to be prepared for 22 kW (if not directly purchased with 22 kW option). Since 11kW was the maximum for getting the money from the KfW I would consider that most of the devices should be 11kW and this will probably not change for the majority of devices.

I don't know what happens if this would be a parameter and anyone will set the max_ampere to 32 - in the case the wallbox does not support it... I don't think that this would be a good option to go with if it could break something on the device.

The best option would be, if the Wallbox could report the max allowed ampere throught MQTT - then, it would be possible to read this topic and set the max value accordingly.

It was possible to get a 11kw and 22kw in the online shop. If somebody has purchased a 11kw version, it is possible to have it remotely unlocked to 22kw afterwards. In my UI it was possible to set 32A, although the box was limited to 11kW. Because of the internal limitation to 11kW, it did not charge with more than 16A. It would be careless by openWB if the adjustment to 32A would cause anything to break. The guys are not amateurs. Apart from that, I assume that someone who sees the benefit in this integration knows whether he owns an 11kw or 22kw box.

BTW: The KFW subsidy is earmarked for 1 year. After that, you can sell the box or convert to 22kw or what ever... This no longer has any influence on the subsidy paid.
