新手的第一条blueprint

zro22

是这样的，我买了个万能遥控器，包含了红外，蓝牙，射频433和315。对，我也买了个这个帖子说的几百块的遥控器
https://bbs.hassbian.com/thread-14172-1-1.html
然后用ESP32做了一个RF桥，负责接收射频信号然后把码转给MQTT。
为了方便写自动化，创建了一个blueprint，具体内容就是侦测MQTT的topic，判断topic里面的码，开关对应的灯。blueprint写好之后，配置自动化，只需要选择码加上对应的设备就可以了。
算是学习了一下blueprint的编写，中间还趟了几个坑，或者不叫坑，是摸索的过程。
整个blueprint如下（这个是单码控制单/多灯，我实际用是四码控制四/多灯）
东西一旦写好实际很简单，大家一看就懂，但是写的过程很痛苦，一点点看示例，debug。

比如最开始value_a没有指定类型，结果跟踪debug发现 playload是 11111 value_a是'11111'导致判断为0不执行。
还有开始只写了switch.turn_on 发现无法turn_on light，所以加了一个light_turn_on。
发在论坛权当是一个备份吧，不然过几天又忘了怎么写。
我的RF码是aabb0或者aabb1 0代表关 1代表开，如果你的码不是这样，就需要分别定义开和关的码。

blueprint:
  name: mqtt topic to trigger switch or light 4 cnt

          domain:
          - light
          - switch
          multiple: true    
trigger:
  platform: mqtt
  topic: !input mqtttopic
action:
- variables:
    payload: "{{ trigger.payload }}"
    value_a: !input value_a 
- choose:
  - conditions:
    - "{{ payload == value_a*10 }}"
    sequence: 
      - service: switch.turn_off
        data:
          entity_id: !input light_a
      - service: light.turn_off
        data:
          entity_id: !input light_a    
  - conditions:
    - "{{ payload == value_a*10+1 }}"
    sequence: 
      - service: switch.turn_on
        data:
          entity_id: !input light_a    
      - service: light.turn_on
        data:
          entity_id: !input light_a
