The Wallbox function block is used to control and visualize a charging station for electric vehicles.
It is possible to use the object inputs or a network connected device.
The following charging stations are supported:
Keba KeContact P20
Keba KeContact P30 C/X
BMW Wallbox Pro

Charging station with supported wallbox↑
For supported charging stations the data exchange with the Miniserver is done via the local network.
The maximum possible charging current of the charging station is set in the properties. It varies depending on the connection type of the respective charging station.
If the charging station is integrated over the network, only the inputs (Act) (Activate charging process), (Cpl) (Charging power limit), and (R) (Reset) are used.
Charging station without supported wallbox↑
If an unsupported charging station is used, it can still be integrated into the Loxone System. In this case no charging station device is assigned in the properties of the function block.
Charging is active when a vehicle is connected and the (Act) input is On. In addition, the inputs (Cp) (Current charging power) and (E) (Charged energy) are now also used. These are required for the statistics.
Keba KeContact P20 Socket ETH Wallbox↑
The Keba KeContact P20 Socket ETH Wallbox is an intelligent charging station for your electric vehicle, ideal for integration into the Loxone system. By communicating with the Miniserver (via Ethernet), the Wallbox is easy to operate and the loading data is always in the field of vision.
