1 Introduction
The Programmers Guide provides the necessary information how to send UDP commands to your charging
station. It gives you the possibility to get status information from the charging station or control it with an UDP
Client (PC software or Smartphone App).
The User Datagram Protocol (UDP) is a simple network protocol that belongs to the transport layer of the
Internet protocol family.
With suitable Home automation controllers it is also possible to realize e.g. a reduction of your energy con-
sumption in conjunction with a photovoltaic system and your charging station.
