ESPHOME 红外发射和接收配合MQTT

zro22

总体框架是这样的1，想要发送红外的时候，往MQTT 指定topic publish，然后ESPHOME会负责把内容发出去。
2，ESPHOME接受到遥控器的数据后，负责把数据转发到MQTT。
这样弄好之后，想要做什么都是通过MQTT自动化完成。


如下是ESPHOME的主要配置。

text_sensor:
  - platform: mqtt_subscribe
    name: "nec to send"
    id: sendnec
    topic: epshome32/sendnec
    on_value:
      then:
        remote_transmitter.transmit_nec:
          address: !lambda |-
            unsigned int addr;
            unsigned int command;
            sscanf(x.c_str(),"%x:%x",&addr,&command);
            ESP_LOGI("main", "NEC:0x%x:0x%x", addr,command);
            return addr;
          command: !lambda |-
            unsigned int addr;
            unsigned int command;
            sscanf(x.c_str(),"%x:%x",&addr,&command);
            return command;
  - platform: mqtt_subscribe
    name: "pana to send"
    id: sendpan
    topic: epshome32/sendpan
    on_value:
      then:
        remote_transmitter.transmit_panasonic:
          address: !lambda |-
            unsigned int addr;
            unsigned long command;
            sscanf(x.c_str(),"%x:%x",&addr,&command);
            ESP_LOGI("main", "PANA:0x%x:0x%x", addr,command);
            return addr;
          command: !lambda |-
            unsigned int addr;
            unsigned long command;
            sscanf(x.c_str(),"%x:%x",&addr,&command);
            return command;            
  - platform: mqtt_subscribe
    name: "sam to send"
    id: sendsam
    topic: epshome32/sendsam
    on_value:
      then:
        remote_transmitter.transmit_samsung:
          data: !lambda |-
            unsigned long data;
            sscanf(x.c_str(),"%x",&data);
            ESP_LOGI("main", "SAM:0x%x", data);
            return data;
remote_transmitter:
  pin: GPIO21
  carrier_duty_percent: 50%
  id: remote_send

  
remote_receiver:
  pin: 
    number: GPIO23
    inverted: True
#    mode: INPUT_PULLUP
  dump: all
  on_nec:
    then:
    - mqtt.publish:
        topic: esphome32/senso/ir
        payload: !lambda |-
          char temp[20];
          sprintf(temp, "%d:%d", x.address, x.command);
          ESP_LOGI("main", "rcv nec: %s", temp);
          return temp;
  on_panasonic:
    then:
    - mqtt.publish:
        topic: esphome32/senso/ir
        payload: !lambda |-
          char temp[20];
          sprintf(temp, "%d:%d", x.address, x.command);
          ESP_LOGI("main", "rcv pan: %s", temp);
          return temp;          
  on_sony:
    then:
    - mqtt.publish:
        topic: esphome32/senso/ir
        payload: !lambda |-
          char temp[20];
          sprintf(temp, "%d:%d", x.data, x.nbits);
          ESP_LOGI("main", "rcv sony: %s", temp);
          return temp; 
  on_jvc:        
    then:
    - mqtt.publish:
        topic: esphome32/senso/ir
        payload: !lambda |-
          char temp[20];
          sprintf(temp, "%d", x.data);
          ESP_LOGI("main", "rcv jvc: %s", temp);
          return temp; 
  on_rc5:        
    then:
    - mqtt.publish:
        topic: esphome32/senso/ir
        payload: !lambda |-

使用 OpenMQTTGateway 是不是更簡單點

待反馈吗？

我觉得,使用ESPHOME的好处是可以结合更多的sensor和ble tracker等等在同一个板子上

楼主，来个更详细的说明吧，之前买了小米的空调伴2    发现这玩意竟然没继电器，不能断电。想了一下这玩意可以自己做一个，继电器+红外发送就行了，。但它也有个好处，遥控器的开关和温度调整它也能接收到并更新APP上的状态

谢谢分享

这个有意思，现在DIY人体传感器，加个这玩意上去，又可以遥控房间红外设备了，66666

接收部分MQTT能收到按键信息了，请问里面的发射部分有什么作用？没明白原理。
epshome32/sendnec这个主题好像也没信息。
