Hi, I am a newbe… using homeassistant automation using the rest\_command.wled\_update to send a payload with a range of colors in different segments to WLED. That all works fine. Now I would want to add an effect (e.g. blink) to some segments. Iooked at the API documentation, however cannot find an example of how use which parameters and which function codes.

I tried things like the following, however that does not make a difference at all.  
Does anyone have any suggestions?

{{  
{  
“bri”: brightness,  
“seg”: {  
“bri”: 255,  
“fx”: 2,  
“i”: result.segments  
}  
}  
}}
