如何利用HarmonyOS的分布式技术（如Ability Kit）实现智能家居设？备间的任务协同？

import deviceManager from '@ohos.distributedDeviceManager';

// 获取设备列表
const deviceList = deviceManager.getTrustedDeviceListSync();

// 过滤目标设备（如智能灯具）
const targetDevice = deviceList.find(device => 
  device.deviceName === 'SmartLight' && 
  device.deviceType === DeviceType.IOT_LIGHT
);

// 建立连接
deviceManager.bindDevice(targetDevice.deviceId, (err) => {
  if (!err) console.log('设备连接成功');
});

  // 远程调用的方法

// 构造调用参数
const want = {

  bundleName: 'com.example.smartlight',

  data: { brightness: 80 } // 控制参数

// 跨设备启动Ability并传递指令
featureAbility.startAbility(want).then(() => {

// 或通过分布式任务调度
distributedMissionManager.continueMission({

  missionId: currentMissionId,
