我购置于某宝的北创卡微电子科技。如有条件，建议您还是测量一下IN、IP间的电压，如果只是互感器变比的问 ...

麻烦楼主看一下算式有问题么？按说in和ip不能有这么高的电压。文档2000:1的互感器，30A的交流电才输出130多mv。我这小灯泡才几A就输出80多mv。另外如果修改配置文件计算公式，计算正确。但是计量大电流的设备时候会错误。

计算无误，说明问题并不出在BL0906。换批电流互感器排查一下

我真想把我的脑袋拧下来当球踢，我焊上去的是5.1K的负载电阻。要是真的串到30A上边。还不把0906炸了。

之前用培正测了总的

我复刻完了但是hass里数据显示未知，logs里有报错；

1、检查BL0906电压是否正常
2、先不接入220V和ESP，通过串口调试工具直接向BL0906发送指令(指令参考厂家文档)，确认其状态
3、检查BL0906与ESP的串口连接是否正常

好的，我试试

大佬，我复刻完了但是有报错温度有时会乱跳是啥原因？附日志

因为硬件问题，可能性比较多，需要自己排查。比如esp8266、周围电磁干扰等问题均可能出现该情况。您可以考虑用esp32来替换试一试，当然如果不影响使用完全可以不管他。

你应该做的是缝合版，那个版本好像有一点点问题，esp读取bl0906会报错，我在3.3V输出加个电容后，情况好了很多，准备重新打板子测试
电子白痴，如有错误，请大佬们指正
