2  UDP commands 

2.1  General information 

 

When using UDP commands it is strongly recommended to protect your Smart-Home-Network on 

port 7090

 

against unauthorized control or external attacks. 
 
 
The charging station reacts on broadcasts and directly addressed commands. In a group of several charging 
stations, direct addressing should be used because otherwise all charging stations would react. 

 

The commands are sent to the charging station as simple text commands (without end characters such as 
<CR> or <LF>). 

 

The answers come as data packages with up to 512 bytes and are formatted in JSON standard; each data 
line within the structure is terminated with <LF> (0x0A). 
 
 
Notes: 
For the JSON format, open-source-parsers are available. 

 

UDP does not support any error correction function. Please verify the effect of the sent commands yourself. 
 
Port information: 
Send port = UDP 7090 
Receive port = UDP 7090
