Milight control via MQTT
Simple flow that controls MiLight/limitlessLED/AppLamp wireless RGBW lights via MQTT. Based on AppLamp API
- MQTT in node listens for topic "lights/+/+", where the first subtopic is the light group number and the second is a command that goes along some possible message values:
- power, "on"/"off"
- whitemode, "yes"
- hue, "0-255"
- brightness, "1-100"
- disco, "yes"
- disco, "up"
- disco, "down"
- The first function translates MQTT subtopics and messages into a simple command or an array of simple commands, since most controls need the power on/enable group command to be effective
- The second function takes the simple command and translate it into MiLight 2-bytes code (or 3 bytes code if you uncomment the last line)
- The delay node ensures that there's at most 1 packet every 100ms, as per MiLight specifications
- The UDP out node finally send the 2/3-byte code to the MiLight wifi box.
