项目背景

最近看中智能小夜灯的项目，通过淘宝几块钱购买人体感应小夜灯（使用外壳），然后机子画板子加入esp8266联网控制，接入homeassistant，做智能控制。

目前以实现以下功能：

• 红外人体侦测
• ld2410微波侦测
• 环境光亮度侦测
• 夜灯控制
• RGB彩灯控制
• dht11温湿度读值（不准）
• 红外发射与接收

既然已经实现红外发射与接收，那么有没有可能通过这个设备，做为普通红外遥控转接信号来控制已接入homeassistant的其他设备呢？

 实现过程

网上论坛大神已提供相关代码，原作者帖子

实现步骤：

• 红外（或者315 433射频）遥控器发射信号
• 接收头接收到信号后给到ESP
• ESP交给MQTT
• HA里面根据MQTT内容执行相应的自动化

仅验证红外部分，实测可用：

1. 使用esphome来识别红外遥控按键代码[main:094]: nec: 1886437949:0

建立自动化例子

trigger:
  - platform: mqtt
    topic: ir_conf/senso/ir
    payload: '1886413469:0'
action:
  - service: switch.toggle
    data:
      entity_id: switch.wall_switch_left_158d0xxxx

使用红外遥控来验证
