Yeelight Kotlin library

Control your Xiaomi Yeelight lamp using Kotlin. This library use Ktor for sockets, more info available here.

Maven Central

This library has 3 modules:

  • Module :core:
    • high level api: YeelightManager, YeelightDevice, YeelightColorFlowPresets
    • low level api: YeelightApi
  • Module :home-ktx:
    • extensions (for my home)
  • Module :app:
    • example app!

Setup

Add this in your build.gradle.kts file:

// core library
implementation("com.github.omarmiatello.yeelight:core:1.0.4")

// extensions example (my home)
implementation("com.github.omarmiatello.yeelight:home-ktx:1.0.4")

Example

suspend fun main() {
  val yeelight = YeelightManager()

  // for debug: Network search + print details
  yeelight.printAllYeelightDevices()

  val myDevice = yeelight.findDeviceById("0x0000000011744b6b")

  if (myDevice != null) {

    // switch on (smooth, 500ms)
    myDevice.setPower(true)

    // switch off (instant)
    myDevice.setPower(isOn = false, effect = SpeedEffect.sudden)

    // get properties values (ex: power state)
    myDevice.getProperties("power")

    // set current configuration as default
    myDevice.setCurrentAsDefault()

    // switch toggle `on -> off` or `off -> on`
    myDevice.toggle()

    // set brightness: 1 to 100
    myDevice.setBrightness(50)

    // start color flow
    myDevice.startColorFlow(
      flowTuples = listOf(FlowColor(0xFF0000), FlowColor(0x00FF00)),
      repeat = 1,
      action = FlowEndAction.off
    )

    // stop color flow
    myDevice.stopColorFlow()

    // set the smart LED directly to specified state.
    // If the smart LED is off, then it will turn on the smart LED firstly and then apply the specified command 
    myDevice.setScene(SceneAutoDelayOff(brightness = 50, duration = 3.minutes))

    // start a timer job
    myDevice.cronAdd(CronPowerOff(5.minutes))

    // retrieve the setting of the current cron job
    myDevice.cronGet()

    //  stop the specified cron job (currently support only CronPowerOff)
    myDevice.cronDel()

    // set white temperature (1700 - 5600)
    myDevice.setWhiteTemperature(5000)

    // set color from black `0x000000` to white `0xFFFFFF`
    myDevice.setColorRgb(0xFF0000)
  }

  // control a group of lights
  yeelight.roomCucina().forEach {
    it.setPower(true)
    it.startColorFlow(flowPolice(speed = 1.5), repeat = 3, action = FlowEndAction.off)
  }

  // preset flows
  yeelight.cucina1().startColorFlow(flowPolice())

  // custom flows
  yeelight.cucina2().startColorFlow(christmasUsaFlow)

  coroutineContext.cancel()
}

val christmasUsaFlow = listOf(
  FlowColor(0xFF0000, 100, 0.milliseconds),
  FlowSleep(300.milliseconds),
  FlowColor(0x0000FF, 100, 0.milliseconds),
  FlowSleep(300.milliseconds),
  FlowColor(0xFFFFFF, 100, 0.milliseconds),
  FlowSleep(300.milliseconds),
)

Note: All functions here are suspend suspending function

Kotlin suspending function does not block a thread, but suspends the coroutine, and it can be only used from a coroutine.
