在这里用到3个设备：

1、永诺yn20e智能电表，来自咸鱼10块钱

2、esp01s一个3元

3.ttl转485模块一个2元

yn20e有485接口，支持modbus协议。用esp8266做一个modbus rtu tcp透传设备（源码已经分享）通过modbus tcp 传输到ha。

怎么给8266供电的，外接usb数据线吗

sorrypqa

好像使用这种方式接入HA，不是显示为单个设备，而是多个零散的实体，很不爽

是的啊

为何不在esphome处理，而是透传到ha

esphome也用了，感觉都不行啊，半个小时或者一个小时才更新一次数据

不可能把，你透传轮询也是一样的逻辑，只是一个底层处理一个应用层处理

esphome我也用了啊，你看上面的代码

esp怎么连接2个或者三个从站啊，我试了多次都不行
