之前618购入了米家小白万能遥控器作为蓝牙网关接入温湿度计，采集了一段事件的串口输出，发现温湿度的解析存在存疑，数据内容很奇怪
根据官方提供的信息eid 0x1004(4100) 0x1006(4102)分别代表温湿度，edata表示的值看不太明白，坛子里有大佬能解析下嘛？

一共有两个温湿度计2 可通过mac区分
原始日志还包含电量数据

官方文档：https://iot.mi.com/new/doc/embedded-development/ble/object-definition.html

以下为原始数据

看我的帖子，非常清楚，有3套代码解析这个数据（python、arduino c、esphome c），除了这个还有花花草草、榉树门锁（这个才是主要目的）。
这里简单说一下：edata的格式是十六进制逆序，量纲是0.1度/0.1%。

比如2103，你需要调整顺序为0321（字节内顺序不动、字节间调整），然后转换成10进制（也就是801）、然后再除以10（这个应为湿度，80.1%。如果是80摄氏度就太恐怖了

好的，非常感谢，我之前看到示例代码reverstr以为是整个倒转，所以一直解出来的数据都很奇怪对不上
