These Integration shows the Data of the EnergyControl Wallbox of the Company Amperfied formerly known as Heidelberg.
The Communication is over Modbus RTU and need a wired connection to the Wallbox. At the Wallbox itself there have to be done some dip switches change to allow communication.
The Modbus protocol is documented under https://www.amperfied.de/wp-content/uploads/2023/03/20220809_AMP-Erweiterte-ModBus-Registerbeschreibung.pdf The Hardware and Wiring to the WB is described on the internet in some different places. (as example https://joachim-wilke.de/blog/2023/03/05/heidelberg-wallbox-uber-modbus-mit-einem-raspberrypi-verbinden/)
In the configuration.yaml you have to add a modbus section (I only have these modbus usage therefore i named it modbus.yaml)
modbus: !include modbus.yaml
in the same folder in which the configuration.yaml is placed you should copy the modbus.yaml file
If Hardware connection is established and Homeassistant is restarted the entities are added.
A Photovoltaic optimized vehicle charging could be established with these communication and entities.
The current could be defined from 0 and 6.0 till 16.0 Amp in 0.1 Amp Steps depending on the vehicle there could be additional restrictions / Amp Steps included.
