【写作说明】：看了 frLab的个人主页| 什么值得买 smzdm.com 的几篇关于 Home Assistant 的文章Home Assistant 篇一：从Node-RED与微信推送谈起_NAS存储_什么值得买 smzdm.comHome Assistant 篇二：群晖Docker安装Home Assistant_NAS存储_什么值得买 smzdm.comHome Assistant 篇三：给HA插上翅膀——HACS与MQTT_NAS存储_什么值得买 smzdm.com总想搞个事情出来，在网上找了些资料，感觉搞一个家庭用电量及电费统计模块很不错，又能就习一下Home Assistant和Node-RED，电路又很简单。总用购买了五个配件：peacefair品牌交流电压电流功率因数电能通信模块模组TTL串口通信-tmall.com锟斤拷猫 最好购买1000A开合式CT。我还买了TTL转USB线，但没有用到。首购金10元，到手 40元CH340C下载烧录器ESP8266 ESP-01 ESP-01S WIFI模块下载器 调试器-tmall.com锟斤拷猫 最好购买ESP-01S+CH340C下载烧录器，烧录器以后还可以使用。17.5元220V转5V9V12V400/500/700MA/1A隔离开关电源模块AC-DC降压模块-tmall.com锟斤拷猫 200V转5V电源模块，800ma应该够了，我买的是1A的。8元LM2596S DC-DC直流可调降压电源模块稳压板3A 12/24转12/5/3.3V-tmall.com锟斤拷猫 降压模块3.3V输出，也可以购买5V转3.3V模块，5V转3.3V的模块应该还要便宜点。3.5元40P彩色杜邦线 母对母 公对母 公对公 长10CM/20CM/30CM/40CM-tmall.com锟斤拷猫 还有这个母对母的杜邦线，家里有就没买了。2元。还要电铬铁和焊锡丝，这个没有可以到但电子产品的借用一下，也可以自己购买，我个自家有就没算成本了。总共花费71元。给大家总体展示一下。 安装软件服务首先安装 Home Assistant 、 Node-RED、QTT 和设置Node-RED的企业推送 参考 frLab 的三篇Home Assistant文章，我就不详细说了，上链接。Home Assistant 篇一：从Node-RED与微信推送谈起，Home Assistant 篇二：群晖Docker安装Home Assistant，Home Assistant 篇三：给HA插上翅膀——HACS与MQTT。硬件组装购买硬件： peacefair PZEM-004T 交流电压电流功率等信息测量通信模块。如果要测家庭总用电量请购买100A的，10A只能测2200W以下功率的电器。互感器CT最好购买开合式的，贵7元，这样就可以不用拆强电箱的进线。peacefair品牌交流电压电流功率因数电能通信模块模组TTL串口通信41元天猫精选去购买 CH340C下载烧录器+ESP-01S，CH340C下载烧录器不是必须购买，如果有一定基础可以自己用USB线烧录，以前有的可以重复使用。WIFI模块最好购买ESP-01S，ESP-01要多接两个电阻，接线也复杂很多。看电路图：CH340C下载烧录器ESP8266ESP-01ESP-01SWIFI模块下载器调试器10元天猫精选去购买 电源模块：因为peacefair PZEM-004T要5V输入，ESP-01S要3.3V输入，所有要有两个模块 220V转5V和5V转3.3V。也有些模块有5V和3.3V两种输出。220V转5V9V12V400/500/700MA/1A隔离开关电源模块AC-DC降压模块4.8元天猫精选去购买 LM2596SDC-DC直流可调降压电源模块稳压板3A12/24转12/5/3.3V3.5元天猫精选去购买 母对母杜邦线，接线用。40P彩色杜邦线母对母公对母公对公长10CM/20CM/30CM/40CM2元天猫精选去购买刷写固件：刷 Tasmota 下载固件 ota.tasmota.com/tasmota/release/ 或者 github.com 下载：tasmota-CN.bin ，这个是简体中文版下载安信可烧录软件 开发工具清单 | 安信可科技 ai-thinker.com 下载第3个 “3、烧录WiFi固件工具：ESP_DOWNLOAD_TOOL” 把ESP-01S插上烧录器并接上电脑电脑解压烧录软件并运行，运行后会自动安装驱动。如果没有安装就到 开发工具清单 | 安信可科技 ai-thinker.com 下载 "串口驱动"，安装驱动后会出现一个COM设备在烧录软件里选ESP8266，develop。第一行选择刚下载的固件，并在前面打钩，在@后面输 0X000000，FLASH SIZE 选 8Mbit，COM:选刚刚在设备管理器上看到的COM口，我这是COM3，其它的看和我上面对比一下，也选一样的。点START烧录固件。显示完成表示烧录完成。到此tasmota刷写完成，关掉烧录软件。配制WIFI :配制ESP-01S的WIFI把烧录器和ESP-01S从电脑的USB接口上扯出，再从新插到电脑USB接口上,然后到手机上操作。打开手机WIFI，搜索WIF 手机上会多一个tasmota开头的WIFI，后面的字母数字和我手机上的不一样。选择并连接。连上后就会出现这个配置WIFi界面，如果没有出现，就到浏览器里面 输入 192.168.4.1 可以看到这个界面，在这里填上路由器或AP的WIF名称和密码。点击保存，会跳转显示ESP-01S获取到的IP信息页面，因为显示时间比较短，没有截到图。如果在上一步没有看到ESP-01S的IP，就到路由器DHCP客户端上去查看，一个以tasmota开头的设置。到路由器上查看DHCP客户端IP就不详说了，这个大家应该都会。到电脑浏览器里输入ESP-01S的IP（我的是192.168.222.125），如果看到这个界面说明WIFI设置成功，可以到网页上设置了。设置ESP-01S填上安装的MQTT信息，安装MQTT可以看 Home Assistant 篇三：给HA插上翅膀——HACS与MQTT_NAS存储_什么值得买 smzdm.com设置好后保存，保存后会重启。保存后会重启，重启后到主菜单，上面会多出电压电流等信息，不过数据都是0，因为还没有接上PZE-004T。现在设置好了，把ESP-01S和烧录器从电脑上扯下，再把ESP-01S从烧录器上拔下。接线：现在可以装到强电箱上去了。用电工胶把电源模块胶到PZE-004T的外壳上，把ESP-001S放到外里。互感器我是套在入户零线上，因为火线空间太小不好装。现在所有安装都完成了。到 Home Assistant 里面添加MQTT插件这装Home Assistant按 Home Assistant 篇二：群晖Docker安装Home Assistant_NAS存储_什么值得买 smzdm.com 这篇文章安装添加集成如果有需要可以把他们添加个中文别名，点想要修改的一行到这Home Assistant就可以显示电压电流功率总用电量等信息了。月初自动清零和显示电费信息编辑

微信的“支付有优惠”如何赠送金币给好友
微信的支付有优惠小程序可以收集金币，终于换购一定金额的免费提现券，但是一个额度的兑换券一周只能兑换一次，比较麻烦，想委托身边的朋友帮忙购买，他们往往又没有金币，怎么办呢？唯一的解决办法就是把你多的金币赠送给好友一些。如何赠送呢？【1】打开微信小程序“支付有优惠”【2】在存放金币的瓶子界面，把手机头朝下倒置。平放不行，得倒置。这样会触发金币被倒出来的功能。【3】再把手机正过来，小程序就会跳出赠送金币的界面。最多赠送9个。提示：自己做测试的话用1个试，因为不管你最后选没选赠送人，系统都会默认金币被赠送了，直到12小时没人领才会给你退回来。用这个方法可以用自己的多个微信号提现，不过我没尝试，大家可以试试。
