HomeAssistant搭建,并将ESP8266通过MQTT接入

HTML  2024-03-24 15:49  647  

之前将ESP8266接入巴法云,使用一段时间后,发现不够稳定,干脆直接在内网搭建一个HomeAssistant实现灯的控制.这里使用docker搭建:

homeassistat(Home Assistant 2021.12.8):

version: '3'
services:
  homeassistant:
    privileged: true
    image: 'homeassistant/home-assistant:stable'
    container_name: 'homeassistant'
    environment: 
        - TZ=Asia/Shanghai
    network_mode: host
    volumes:
        - /home/file/docker/homeassistant/config:/config
    restart: unless-stopped

启动完成后访问服务器8123端口完成初始化.

还需要安装一个mqtt服务端,这里同样使用docker搭建

mosquitto:

version: "3.0"
services:
   mosquitto:
        container_name: 'mosquitto'
        image: 'eclipse-mosquitto:2.0.18'
        ports:
            - 1883:1883
            - 9001:9001
        volumes:
            - /home/file/docker/mosquitto/config:/mosquitto/config
            - /home/file/docker/mosquitto/data:/mosquitto/data
            - /home/file/docker/mosquitto/log:/mosquitto/log

mosquitto.conf

persistence true
#persistence_location /mosquitto/data
#log_dest file /mosquitto/log/mosquitto.log
listener 9001
port 1883
allow_anonymous true

启动mqtt服务器,然后来到HomeAssistant管理页面,

左侧配置-设备与服务,右下角添加集成,找到MQTT,输入刚刚搭建的mqtt服务器.

烧录开发板,跟前一篇文章的巴法云代码一样,这里再贴一下,设备接线参考 ESP8266通过巴法云接入米家

我这边使用的WiFiManager版本为0.16.0,发现使用最新版2.0.17有无法连接MQTT服务器的问题

#include <ESP8266WiFi.h>
#include <ESP8266WebServer.h>
#include <WiFiManager.h>
#include <Ticker.h> 
//#include <PubSubClient.h>
#include "PubSubClient.h"              //默认,加载MQTT库文件         

WiFiClient espClient;  //wifi客户端模式
PubSubClient client(espClient);
Ticker ticker;  //定时器对象

#define ID_MQTT  "esp8266-01"     //客户端id
#define D1 5   //D1
#define D2 4   //D2
const char*  topic = "light001";        //主题名字,与巴法云控制台的主题一致
const int B_led = D1;       //引脚值,此引脚用于连接继电器的信号端
const int led_switch = D2;       //引脚值,此引脚用于连接继电器的信号端
//**************************************************//

const char* mqtt_server = "192.168.4.200"; //默认,MQTT服务器
const int mqtt_server_port = 1883;      //默认,MQTT服务器端口
int count;    // Ticker计数用的变量
int state = 0; //灯的状态

// 建立WiFiManager对象
WiFiManager wifiManager;  

//灯光函数及引脚定义
void turnOnLed();
void turnOffLed();

//计数
void tickerCount(){
  count++;
}

// 连接MQTT服务器
void reconnect() {
    Serial.print("Attempting MQTT connection...");
    // Attempt to connect
    if (client.connect(ID_MQTT)) {
      Serial.println("connected");
      Serial.print("subscribe:");
      Serial.println(topic);
      //订阅主题,如果需要订阅多个主题,可发送多条订阅指令client.subscribe(topic2);client.subscribe(topic3);
      client.subscribe(topic);
    } else {
      Serial.print("failed, rc=");
      Serial.println(client.state());
      Serial.println(" try again in 1 seconds");
      // Wait 5 seconds before retrying
      delay(1000);
    }
//}
}

// 收到信息后的回调函数
void receiveCallback(char* topic, byte* payload, unsigned int length) {
  Serial.print("来了Topic:");
  Serial.println(topic);
  String msg = "";
  for (int i = 0; i < length; i++) {
    msg += (char)payload[i];
  }
  Serial.print("Msg:");
  Serial.println(msg);
  if (msg == "on") {//如果接收字符on,亮灯
    turnOnLed();//开灯函数
  } else if (msg == "off") {//如果接收字符off,关灯
    turnOffLed();//关灯函数
  }
  msg = "";  
}

//开灯
void turnOnLed() {
  Serial.println("turn on light");
  digitalWrite(B_led, HIGH);
  state = 1;
}

//关灯
void turnOffLed() {
  Serial.println("turn off light");
  digitalWrite(B_led, LOW);
  state = 0;
}

// 发布信息
void pubMQTTmsg(){   
    // 建立发布主题
    //巴法云个性设置,推送消息时:主题名后加/set推送消息,表示向所有订阅这个主题的设备们推送消息,
    //假如推送者自己也订阅了这个主题,消息不会被推送给它自己,以防止自己推送的消息被自己接收。
    String topicString = "light001/set" ;
    char publishTopic[topicString.length() + 1];  //转换成字符数组
    strcpy(publishTopic, topicString.c_str());
   
    // 建立发布信息,当前D1引脚状态
    String messageString;
    if(digitalRead(B_led)){
      messageString = "on"; 
    } else {
      messageString = "off"; 
    }       
    char publishMsg[messageString.length() + 1];   //转换成字符数组
    strcpy(publishMsg, messageString.c_str());
    
    // 实现ESP8266向主题发布信息,并在串口监视器显示出来
    if(client.publish(publishTopic, publishMsg)){
      Serial.println("Publish Topic:");
      Serial.println(publishTopic);
      Serial.println("Publish message:");
      Serial.println(publishMsg);    
    } else {
      Serial.println("Message Publish Failed."); 
    }
}

//程序入口
void setup() {
  pinMode(B_led, OUTPUT); //设置引脚为输出模式
  pinMode(led_switch, OUTPUT); // 开关引脚为输入模式
  digitalWrite(B_led, LOW);//默认引脚上电低电平
  Serial.begin(9600);     //设置波特率9600
  
  //********************自动配置网络************************  
//  wifiManager.setTimeout(20);
  wifiManager.setConfigPortalTimeout(120);
  // 自动连接WiFi。以下语句的参数是连接ESP8266时的WiFi名称
//  wifiManager.autoConnect("AutoConnectAP");  
  // 如果您希望该WiFi添加密码,可以使用以下语句:
   wifiManager.autoConnect("8266","xxxxx"); 
  //重置wifi设置
  // wifiManager.resetSettings();
  // WiFi连接成功后将通过串口监视器输出连接成功信息 
  Serial.println(""); 
  Serial.print("ESP8266 Connected to ");
  Serial.println(WiFi.SSID());              // WiFi名称
  Serial.print("IP address:\t");
  Serial.println(WiFi.localIP());           // IP
  //*******************************************************  
    
  client.setServer(mqtt_server, mqtt_server_port);//设置mqtt服务器
  client.setCallback(receiveCallback); //mqtt消息处理  
    
  ticker.attach(1, tickerCount); // Ticker定时对象
  
  Serial.println("setup结束");

}


//循环执行 
void loop() {

//  Serial.println("循环");

  int val = digitalRead(B_led);
  int ctl_val = digitalRead(led_switch);



  if(ctl_val == 1){//按键按下
      delay(400);
      state = !state;
      digitalWrite(B_led, state);
//      digitalWrite(led_switch, LOW);
      digitalWrite(led_switch, LOW);
      int ctl_val = digitalRead(led_switch);
      Serial.print("开2关值为 :\t");
      Serial.println(ctl_val);
    }

  


    if (client.connected()) {
      client.loop();
      if (count >= 10){ // 每隔10秒钟发布一次信息
        Serial.println("心跳报");
          pubMQTTmsg();
          count = 0;
      }
    }else{
          reconnect();
    }

}

烧录完成后,现在为HomeAssistant添加该设备

在homeassistant的configuration.yaml中最后添加一行

light: !include light01.yaml

随后在configuration.yaml同级目录添加light01.yaml,内容为

- platform: mqtt
  name: "卧室灯"
  state_topic: "light001/set"
  command_topic: "light001"
  payload_on: "on"
  payload_off: "off"
  optimistic: false
  qos: 0
  retain: true

完成后重启homeassistant即可

连接HomeKit

配置-设备与服务中添加HomeKit,然后开放端口
