# NodeMCU_v3_ws2812、已弃用，推荐使用：https://github.com/Aircoookie/WLED

#### 介绍
WS2812灯带使用NodeMCU通过mqtt接入home assistant。

#### 准备工作
1. NodeMCU v3
2. Home Assistant服务器
3. mqtt服务器
4. ws2812灯带（Din接NodeMCU的D4引脚）


#### 安装教程

1.  云编译NodeMCU固件，地址：https://nodemcu-build.com/index.php ，除了默认模块以外，需要额外选择：MQTT、WS2812、WS2812 effects这三个模块。
2.  使用：https://github.com/nodemcu/nodemcu-flasher 将固件刷入NodeMCU
3.  使用：http://esp8266.ru/esplorer/ 将init.lua文件上传到NodeMCU（注意修改文件中WiFi信息和mqtt服务器信息，具体看文件注释）

#### 使用说明

1.  在Home Assistant的配置文件中加入：
~~~

  - platform: mqtt
    name: "灯带"
    command_topic: "ws2812/switch"
    state_topic: "ws2812/switchpub"
