蓝牙电子秤接入HA（需要先连接蓝牙设备）

toil

看了XCray的帖子之后就一直在研究自己的云麦电子秤，结果我的不是直接读广播数据，而是先连接蓝牙后才能读取数据，不能直接抄作业了。研究了半天有人在github上传过一个Yunmai-Scale-ESP32-BLE-to-MQTT 改了改只接入阻值和体重两个数据，已经稳定运行了几个月还可以，但是总觉得买个ESP32只接入一个体重秤实在有点浪费，就一直想研究通过ESPHOME接入，苦于无奈只会python，实在玩不转ESPHOME,熬了几个晚上最后还是通过AI一点一点拼凑出来了，现在分享给大家一下。

十分感谢分享~我也有一个蓝牙设备。同事通过微信小程序连接蓝牙控制的。应该和楼主的电子秤类似。

C哩C哩

这个只能节体重秤吗
