xuanfeng · 2020 年5 月 7 日 18:23

论坛排版有点问题，可以去原文看看：https://33m.me/18

需要具备的条件：

已安装 HA
已安装 MQTT
已安装 Node-RED
懂得基本的 Arduino 开发板烧录

需要准备的材料：

433MHz 发射模块 * 1
433MHz 接收模块 * 1
ESP8266 NodeMcu Lua WiFi V3 物联网开发板 * 1
3.3v 电源模块 *1
电源 * 1
杜邦线 * N
三色LED灯珠 * 1
外壳 * 1

我正好有个坏了的路由器，我就拿这个做外壳了。

这个433MHz模块的天线被我剪断了重新接的，变形了不影响使用。

1、获取遥控代码

▷ 接线图：

▷ 打开示例：
打开示例并烧录到开发板文件 - 示例 - rc-switch - ReceiveDemo_Advanced

▷ 打开串口，按遥控器按键：
【串口返回数据】
二进制代码： 001000101100010010010100
协议： Protocol: 1
脉冲长度： PulseLength: 262

Decimal: 705748 (24Bit) Binary: 001000101100010010010100 Tri-State: not applicable PulseLength: 
262 microseconds Protocol: 1

由于没找到那个型号的模板，就用这个代替了，这个板子也是一样的。

HA配置：

	# 开关
	# MQTT
	- platform: mqtt
	name: “开门”
	state_topic: “home/芯片ID/stat”
	command_topic: “home/芯片ID”
	qos: 2
	payload_on: “1”
	payload_off: “1ok”
	retain: true
	- platform: mqtt
	name: “关门”
	state_topic: “home/芯片ID/stat”

include “user_interface.h请问这个头文件在哪里下呢？谢谢！
编译到这里出错：else if (pub.payload_string() == “reset”) {
错误提示：extended character “ is not valid in an identifier
