openHAB integration

Example configuration for a device with ID labor:

Items

Group WS2812
Dimmer lab_ws_bright  "Brightness"       (WS2812) {mqtt=">[local:homie/labor/WS2812FX/brightness/set:state:*:default]"}
Dimmer lab_ws_speed   "Speed"         (WS2812) {mqtt=">[local:homie/labor/WS2812FX/speed/set:state:*:default]"}
String lab_ws_mode    "Mode [%s]"         (WS2812) {mqtt=">[local:homie/labor/WS2812FX/mode/set:COMMAND:*:default], <[local:homie/labor/WS2812FX/mode:state:default]"}

Sitemap

sitemap lab label="Test Sitemap" {
Frame label="WS2812" {
    Slider item=lab_ws_bright
    Slider item=lab_ws_speed
    Switch item=lab_ws_mode mappings=[next="+", prev="-"]
}
}

Better scaling for speed (percent instead of 8bit)

Change item lab_ws_speed to:

Dimmer lab_ws_speed   "Geschwindigkeit" (Labor) {mqtt=">[local:homie/labor/WS2812FX/speed/set:state:*:JS(scale_percent_to_byte8.js)]"}

and create file scale_percent_to_byte8.js in transform/ subdirectory.

(function(i) {   
    return i*255/100;
})(input)
