前提环境：
安装有home assistant（以下简称ha）
安装有mosquitto （mqtt服务端）
有ha可控制的灯
原理：
监视光猫管理页面的无线终端设备列表，存在指定mac设备即被认定为主人回家，否则被认定为离家。
//自动化操作

MQTT协议其实也是建立在tcp协议上的，理论上来说只要支持MQTT协议的设备都可以进行跨平台通讯。
我用Golang实现了一下，感觉挺好玩的。
我想到一个使用场景，就是家里的电热水器。平时上班的时候电热水器可以关掉，而回家的时候电热水器自动启动，这样比较省电。我经常是忘记回家去开电热水器，等想洗澡的时候又要等很长时间。
package main
import (
"fmt"
mqtt "github.com/eclipse/paho.mqtt.golang"
"time"
)
var messagePubHandler mqtt.MessageHandler = func(client mqtt.Client, msg mqtt.Message) {
fmt.Printf("Received message: %s from topic: %s\n", msg.Payload(), msg.Topic())
}
var connectHandler mqtt.OnConnectHandler = func(client mqtt.Client) {
fmt.Println("Connected")
}
var connectLostHandler mqtt.ConnectionLostHandler = func(client mqtt.Client, err error) {
fmt.Printf("Connect lost: %v", err)
}
func main() {
var broker = "192.168.23.244"
var port = 1883
opts := mqtt.NewClientOptions()
opts.AddBroker(fmt.Sprintf("tcp://%s:%d", broker, port))
opts.SetClientID("go_mqtt_client")
//opts.SetUsername("emqx")
//opts.SetPassword("public")
opts.SetDefaultPublishHandler(messagePubHandler)
opts.OnConnect = connectHandler
opts.OnConnectionLost = connectLostHandler
client := mqtt.NewClient(opts)
if token := client.Connect(); token.Wait() && token.Error() != nil {
panic(token.Error())
}
sub(client)
publish(client)
client.Disconnect(250)
}
func publish(client mqtt.Client) {
num := 10
for i := 0; i < num; i++ {
text := fmt.Sprintf("Message %d", i)
token := client.Publish("topic/test", 0, false, text)
token.Wait()
time.Sleep(time.Second)
}
}
func sub(client mqtt.Client) {
topic := "topic/test"
token := client.Subscribe(topic, 1, nil)
token.Wait()
fmt.Printf("Subscribed to topic: %s\n", topic)
}显示：
D:\GoProjects\hello\go_build_main_go.exe Connected Subscribed to topic: topic/test Received message: Message 0 from topic: topic/test Received message: Message 1 from topic: topic/test Received message: Message 2 from topic: topic/test Received message: Message 3 from topic: topic/test Received message: Message 4 from topic: topic/test Received message: Message 5 from topic: topic/test Received message: Message 6 from topic: topic/test Received message: Message 7 from topic: topic/test Received message: Message 8 from topic: topic/test Received message: Message 9 from topic: topic/test 进程 已完成，退出代码为 0

有意思，就是没硬件设备，(●—●)，改天去淘宝弄个集成IO网络控制板，也玩玩物联网
