感谢大神的集成，之前用esphome读的培正，得自己搞月用电数据啥的。看到帖子试了下改成透传，很容易就成功 ...

这个可以多组吗？

好吧，插件不支持复用，添加俩透传端口也用不了,希望楼主能增加一下这个功能?多模块接入（复用）

经过一个星期的不断测试，发现硬件连接上存在DT-06电流倒灌到pzem-00t的可能，问题出现在DT-06 TX口->>>pze ...

俺也发现了，请问这个你解决了吗？

已经解决了，在pzem 004t的rx到dt-06的tx之间串接10K-15K的电阻。

nodemcu加个330Ω的电阻就差不多了，手头没有多余的电阻没有过多测试，对于noedmcu而言，10—15KΩ过大了

谢谢分享，学习一下

你好,江苏无锡,请问下电价实体怎么搞?

没找到8266透传的资料，还是某宝直接入手DT 06模块了，省心。

好，最近准备弄下电量计量的，“还是某宝直接入手DT 06模块了”。这个你买的哪一家的？多谢
