所需材料
8266开发板
红外发射二极管
三极管放大器

参考两个开源项目
https://github.com/huexpub/IRMQTT
https://github.com/Caffreyfans/IREasy

先刷入IRMQTTServer固件
https://github.com/huexpub/IRMQTT/blob/master/fimware/IRMQTTServer.ino.generic.bin

8266上电后，搜索IRMQTT热点，连接上，转入配网WEB页面，未弹出请尝试访问192.168.4.1地址

连接好wifi后，在路由器管理界面查看新增的ESP_xxx设备 然后给他固定IP

8266断电后如图所示连接二极管与三极管

浏览器进入刚刚固定的IP进行匹配空调

选择对应的空调型号，模式，电源，温度，并点击 UPDATE/SEND，空调有反应后，视为有效型号，若无反应，请对应尝试model 1-6子设备型号，如均无反应，可能不被支持。

然后配置homeassistant（又名HASS）
修改configuration.yaml

    mqtt:
  # MQTT Broker的IP地址或者域名
  broker:yiniot.com
  # MQTT Broker的端口号，缺省为1883
  port: 1883
  # 用户名
  username:自定
  # 密码
  password:123456
