Title: Smart home control and device management implemented in UniApp

Smart home has become an important part of modern life. By using UniApp, we can easily develop smart home control and device management applications. This article will introduce how to implement smart home control and device management functions in UniApp, and provide specific code examples.

1. Overview

UniApp is a cross-end application framework based on Vue cloud development, which can simultaneously develop applications for multiple platforms such as mini programs, H5, and App. Taking advantage of UniApp, we can quickly build smart home control and device management applications to control and manage smart devices and improve users' quality of life and convenience.

2. Implementation process

1. Device list display

First, we need to display the user’s smart device list. By calling the cloud-developed database interface, the user's device list information is obtained and displayed on the page. The sample code is as follows:

<template>
  <view>
    <view v-for="(device, index) in devices" :key="index">
      <text>{{ device.name }}</text>
      <button @click="controlDevice(device)">控制</button>
    </view>
  </view>
</template>

<script>
export default {
  data() {
    return {
      devices: [], // 设备列表数据
    }
  },
  onShow() {
    // 获取设备列表数据
    this.getDevices()
  },
  methods: {
    getDevices() {
      // 调用云开发接口，获取设备列表数据
      uniCloud.callFunction({
        name: 'getDeviceList',
        data: {},
        success: (res) => {
          this.devices = res.result.data
        },
        fail: (err) => {
          console.error(err)
        }
      })
    },
    controlDevice(device) {
      // 跳转到设备控制页面，并将设备信息传递过去
      uni.navigateTo({
        url: '/pages/device-control/index?deviceId=' + device.id
      })
    }
  }
}
</script>

2. Device control page

On the device control page, we can implement specific control operations on the device. Control methods vary depending on the type of device. Here's a simple example showing how to control the on/off and brightness of a smart light. The sample code is as follows:

<template>
  <view>
    <button @click="toggleSwitch">开关</button>
    <slider
      @change="changeBrightness"
      :value="brightness"
      :min="0"
      :max="100"
    ></slider>
  </view>
</template>

<script>
export default {
  data() {
    return {
      device: {}, // 设备信息
      brightness: 50, // 亮度
    }
  },
  onLoad(options) {
    // 获取设备信息
    this.device = options.deviceId
  },
  methods: {
    toggleSwitch() {
      // 发送控制命令，开关智能灯
      uniCloud.callFunction({
        name: 'controlDevice',
        data: {
          deviceId: this.device.id,
          command: 'toggleSwitch'
        },
        success: (res) => {
          console.log(res)
        },
        fail: (err) => {
          console.error(err)
        }
      })
    },
    changeBrightness(value) {
      // 发送控制命令，调整智能灯亮度
      uniCloud.callFunction({
        name: 'controlDevice',
        data: {
          deviceId: this.device.id,
          command: 'changeBrightness',
          value: value
        },
        success: (res) => {
          console.log(res)
        },
        fail: (err) => {
          console.error(err)
        }
      })
    }
  }
}
</script>

3. Summary

Through UniApp, we can quickly build smart home control and device management applications, and achieve specific control and management of smart devices. This article briefly introduces the implementation process and provides code examples, hoping to provide some reference for you to build smart home applications. Of course, in actual applications, you can also expand more functions according to actual needs, such as scene control, scheduled tasks, etc., to enhance the smart home experience. I wish you good results in your UniApp development!
