Wallbox

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 wallbox has been integrated over the network, only the inputs (Act) (enable), (Cpl) (limitation of the charging energy), 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.

Again, it loads when the vehicle is connected and the Enable input is On. In addition, the inputs (Cp) (power) and (E) (energy) are now also used. This is necessary 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.
