WS2812 RGB Color changer with MQTT and Homekit with ESP8266 and

semaf · December 31, 2016, 3:24pm

I am trying to create a color changer for WS2812 RGB Leds and on off switch on OH2 with MQTT and Homekit.

The OH1 configuration is like below:

items:

Color TVLedLight  "Bed Color" <colorlight> (All)  
String TVLedLightColor (All) {mqtt=">[OpenHab:devices/family-room-tv-led/led/color/set:command:*:default]"}

sitemap:

Text label="Family Room" icon="sofa" {
            Frame label="Switches" 
                    Switch item=wifiplug_living_room
                    Colorpicker item=TVLedLight
               	}
}

rules:

import org.openhab.core.library.types.*
rule "Set RGB value TVLedLight"
when
        Item TVLedLight changed
then
        val hsbValue = TVLedLight.state as HSBType
        val brightness = hsbValue.brightness.intValue
        val redValue   = ((((hsbValue.red.intValue * 255) / 100) * brightness) / 100).toString
        val greenValue = ((((hsbValue.green.intValue * 255) / 100) * brightness) / 100).toString
        val blueValue  = ((((hsbValue.blue.intValue *255) / 100) * brightness) / 100).toString
        val color = redValue + "," + greenValue + "," + blueValue
        sendCommand( TVLedLightColor, color )
end

To see the items on Homekit it must have a syntax like below which has been tested:

Switch outlet1 "Lamp" (lights,lamp,bedroom) ["Lighting"] {mqtt=">[broker:/ol1/gpio/15:command:ON:1],>[broker:/ol1/gpio/15:command:OFF:0],<[broker:/ol1/state:state:default"}

I tried to change the configuration like its explained on Migration but Homekit does not show me a Switch or Color selector.

Would be happy for some help.

Based on your described setup you should be able to use the following:

Color TVLedLight  "Bed Color" <colorlight> (All) ["Lighting"]

This gives me some Errors
