Add Delta Wallbox

[premultiply]

Not sure whether its still of interest, but I recently integrated my Delta Basic WB into Home Assistant via ModBus: https://www.photovoltaikforum.com/thread/209699-delta-ac-max-basic-wallbox-modus-rtu-rs485-wie

You dont need the small board which in addition gives you less options than the control via ModBus:

Since I ordered 2 of these Wallboxes last week, I would be interested in an integration in EVCC. Is there a similar currently supported Wallbox? Because then I could maybe try to get them to work and test them.

Maybe you can share the Modbus port of at least one of the boxes to us?
That would speed up implementation and testing. 🎅🏻🎄

Please send an email with the connection details to info@evcc.io or send a pm to me at our Slack channel. Thx.

I also own two AC MAX Basics and already started implementing a plugin for EVCC. Was able to sucessfully charge my EV yesterday while managing power limits via EVCC but there is still some work to do. I think it can be improved by integrating additional registers that are not described in the documentation I have.

Will send a wip pull request shortly. Feel free to comment or help to improve it (my first Go adventure ;) )

I got an AC MAX Smart here, which i want to use with evcc.
Trying OCCP first until end of the year. Cabling will only provide 13A 1p until the electrican brings the new cable.

@premultiply: I think this issue can be closed because the PR got merged today.
@xpcone: Would be nice if you could try out the plugin with your AC MAX Smart as I can only test with the AC MAX Basic here.
