自动关闭电视

wolfcdd · 发表于 3 天前

已实现的功能：电视机持续播放XX分钟后，强制关闭，并且必需等待XX分钟后，才能继续开启。

1、自定义电视机持续播放的时间（设置trigger节点对应的时间间隔）
2、自定义电视机休息的时间（设置trigger节点对应的时间间隔）
3、休息时间未达到，强制开机，5秒后强制关机（5秒可在第一个节点中自行设置，建议最短不要小于3秒）
4、未使用global变量，而是使用的flow变量，重新部署后会全部初始化（可自行改为global变量，即使重新部署也会持续状态。）

未实现的功能：未超过持续播放时间，中途关闭后，下次继续打开，不能继续上次的计时

流程图如下：

完整Json如下：
