烧水和消毒提醒--influxdb节点--历史数据查询--查询最大值

Node-Red
#1

电热水壶和消毒碗柜都同时插在一个可即时更新功率的插座上.
如何来实现水壶烧完水, 消毒碗柜消毒完碗时TTS提醒呢?

前置需求

  1. 可查询即时功率的插座, 本例用的是米家智能插座带usb口的增强版
  2. 配置好InfluxDB数据库, 可参考妖神教程](https://bbs.iobroker.cn/t/topic/559/1)
  3. TTS

原理简述

  1. 当功率从较高状态下, 下降为1w, 可判断为 消毒或水壶完成了消毒或烧水
  2. 查询60秒前到现在,功率的最大值, 如果较高就是烧完水, 如果较低就是消毒完成

:+1:大神厉害，学习了很多。我学习你的这个流程，搞了一个厨房关灯流程。就是根据湿度降低的差值，判断是否做饭完成。正在试验中。谢谢你的分享
