ESP8266 Low Power 4-Position Socket

Overview

打印机等设备太多，长期通电待机功耗大，不同电，使用时又不方便，之前一直使用小K 一位智能插座，连接排插，定时开关所有设备。知道最近玩起ESP8266，学习了Arduino，所以产生了自己DIY智能插座的项目。目前已实现功能：1.低功耗设计，采用4只磁保持继电器，只在开关动作时继电器线圈通电，其余时间只有ESP8266待机耗电，用USB电流表测试整个PCB待机电流0.08A，单个继电器动作时电流0.15A。 2.断网状态 4位插座可独立使用按键控制，相应LED指示通断状态。 3.采用MQTT协议接入Home Assistant,可使用Home Assistant WEB或者手机客户端控制每位开关，同时插座会反馈按键开关操作插座的状态，按动任意按键，插座将局域网IP发送给MQTT订阅主题 4.使用ESP8266 WEBserver服务，可网页操作开关通断（同时支持POST参数控制，可接入其他自动控制设备或程序） 5.使用ESP8266 EEPROM存储开关状态，重启上电可分别设置每位开关状态为关闭/开启/保持上次状态（使用WEB配置） 6.WEB界面可设置4位开关备注名称 7.上电长按第3个按键（电源线端为按键1），可重置EEPROM参数 8.WIFI账号密码配网，使用过WiFiManager中文库做WEB配网，但偶尔程序跑飞，所以改成WEB页面配网，断码请自行完善 9.WEB配网及内置定时开关功能正在完善中，敬请期待注意，插座带有220V交流电，非专业人士请勿拆开和改造！该文章仅为展示，如仿制请自行注意安全！！！本开源项目遵循GPL3.0开源协议，但是如果商用，请您捐助所得净利的20%给慈善项目并且将整个捐款订单公开，如果做不到请不要商用

100 points: Why can't MSComm1.Output = SHuZu(i) be used? I have to use MSComm1.Output = SHuZu to use it.
This is a problem in VB6, but because it involves hardware, I still come to your place to ask for advice: The code is as follows dim SHuZu(5) as byte,i as integer for i =0 to 4 MSComm1.Output = SHuZu(
