【语音控制】0成本实现小爱远程开关电脑

背景：之前使用HACS/网页版实现了电脑网络唤醒，但不能关机，不支持小爱

问题：不能语音关机，不支持小爱

环境：支持WOL的主板电脑，python 3.X环境(我这里用了群晖)

解法：1.使用小爱添加第三方设备

2.第三方平台提供API，

3.找台服务器运行Python脚本虚拟一个开关设备，定义开关触发bash脚本

方案评估：在评估方案时，在网上查资料最终方案为点灯科技 Blinker

系统架构：一番研究后最终系统架构和步骤如下：

Python程序逻辑如下

流程、架构理清了，开始执行：

1.准备python3.X的环境，确保pip3 命令可用，群晖没有PIP3可以装，但是后面很多库、依赖安装出错，最终放弃，我直接使用docker python环境

已经搞好的(包含依赖环境)上传到了：https://hub.docker.com/r/realwang/blinker-wol

2.在python环境中安装Blinker依赖环境，参考官方教程

点灯科技-点灯物联网解决方案

3.手机端操作

1.下载个点灯科技APP,注册账户2. 添加设备-->独立设备-->WIFI接入-->阿里云-->复制key3. 右上角编辑-->添加按钮-->修改键名为"btn-pc1"类型勾选开关按键4. 右拉添加个调试组件，锁定退出

4.编写python脚本，确保服务器81端口闲置

5.运行脚本，如果报错，缺什么补什么

6.电脑安装openssh，ssh测试一下到win10
