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
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key
3. 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
6.跑起来手机上的设备会显示在线,手动操作开机后用小爱测试下
