Wallbox integration: Max ICP should not be limited to 32A

[ohinterstein]

The problem

It is impossible to set the Max ICP input number to a value higher than 32A.
My wallbox can charge up to 32A, but my home consumption can be higher than 32A (63A max in my case).
The Max ICP setting allows the Wallbox to adapt its charging current, depending on the home consumption.
If this value cannot be set to more than 32A, it means that if the home consumption is 20A for example, the Wallbox will charge to 12A only, which is not optimized (whereas the home max current can be really higher than 32A).

In the Wallbox app, this value can be set to 0-255A. It should be the same in Home Assistant.

@ohinterstein are you able to change this on the Wallbox portal, app? Because I believe we are using a value provided by the API (max available current) to set the maximum here. Will check this further on my own installation.

Hello @hesselonline , actually the ICP param seems not to be available on the Wallbox portal, I only found the "power limit" parameter (which corresponds the max charging power of the wallbox)

But the ICP parameter is available on the phone app, in the "Charging management" part, and should correspond to something like "max current per phase" of the house (sorry for my english... it is the name of the param on my app in French).

But what I can say is that the "Wallbox Maximum ICP current" input of the integration is well linked, because it changes the right setting of the wallbox. The only problem is that it should be possible to set it to a value higher than 32A. (it is up to the user to set the correct value depending on his house; if the value is too high, the circuit breaker will trip, simply...)

Hope it will help!
