Hey, guys need help to send RGB values to an Arduino via MQTT.
Below are a few of my items. I have a color picker for LivSoffitLight and it works. I want to use a selection item for go to some preset colors.
When I watch my MQTT broker I am getting the Value # from LivSoffitLightColor2 on the MQTT, however, I need to convert the selection # to RGB values.
Ie. When I select Red on the selection I get a #2 at the MQTT topic Mosquitto:Lighting/Accent_1/Color. However, I need the value to be "255,0,0"
Any help would be great.
I’m not sure if I need to do this with a rule. I have tried a Transition map, however, didn’t seem to make the output different.
Items:
String LivSoffitLightColor "Accent Lighting 1" {mqtt=">[Mosquitto:Lighting/Accent_1/Color:state:*:${state}]"}
Color LivSoffitLight "LivSoffitLight" <colorpicker>
Number LivSoffitLight2 "RGB Presets"
String LivSoffitLightColor2 "RGB Presets" {mqtt=">[Mosquitto:Lighting/Accent_1/Color:command:*:default}
