【求助】【已解决】关于gateway3添加新旋钮设备

invincible

今天到手了一个四键旋钮，接入米家并且能够获取旋转角度。
参照@relliky大佬的帖子https://bbs.hassbian.com/thread-25298-1-1.html折腾了一晚上，实在是心有余力不足，特来请教各位大佬。

目前xiaomi_gateway3.py的内容如下：

from custom_components.xiaomi_gateway3.core.devices import *

DEVICES = [{
    17658: ["LeMesh", "Scenario knob remote control Alpha", "lemesh.remote.ts10"],
    "spec": [
        BaseConv("battery", mi="4.p.1003"),  # uint8
        BaseConv("action", "sensor"),
        MapConv("action", mi="5.e.1012.p.1", map={1: "button_up_single", 2: "button_right_single", 3: "button_down_single", 4: "button_left_single", 5: "right_rotation", 6: "left_rotation", 11: "press_up_right_rotation", 12: "press_up_left_rotation", 13: "press_right_right_rotation", 14: "press_right_left_rotation", 7: "press_down_right_rotation", 8: "press_down_left_rotation", 9: "press_left_right_rotation", 10: "press_left_left_rotation"}),
        MapConv("action", mi="5.e.1013.p.1", map={1: "button_up_double", 2: "button_right_double", 3: "button_down_double", 4: "button_left_double"}),
        MapConv("action", mi="5.e.1014.p.1", map={1: "button_up_hold", 2: "button_right_hold", 3: "button_down_hold", 4: "button_left_hold"}),
        ConstConv("action", mi="5.e.1036", value="rotate"),
        BaseConv("rotate", mi="5.e.1036.p.2"),
    ],
}] + DEVICES

然后现在action无数据，旋转和电量都是不可用。

这个垃圾多模，反正我的门锁，接入一会儿，过段时间又不行，已经放弃了，你的21分钟前正常，然后就没有接入多模了

我这个不是21分钟前正常，是21分钟前BLE有数据

是的，在这之后设备就没连接到网关，所以没数据

看着没问题啊，service iid, event iid, property iid看着都是对的。你用的是最新的xiaomi gateway3吗？最近几个版本才改的这个新的语法。

看你已经研究了一部分了，你要是看得懂python，也可去翻一下alexiit的源代码。。就算有些看不懂的地方，忽略掉它们，只在关键地方去打印点信息出来看看是哪步错了。
如果你想查错源代码，给你点思路，从这里查起 https://github.com/AlexxIT/Xiaom ... core/device.py#L340
查为什么这个eid最后没有生成你想要的

大佬，目前歪打正着解决了按钮和旋转角度的问题。以下是当前的xiaomi_gateway3.py

1、抱着试试的心态，抄了下mibeacon协议下的写法，然后就好了。。。;
2、rotate在edata里是int8类型的十六进制数据，本来打算用作者mibeacon.py里的BLEByteConv，然后发现，右旋是正数，没问题；左旋是负数，显示出来是很离谱的数字，后来查了查，负数要单独处理；
3、然后想动mibeacon.py里的BLEByteConv，怎么改都不大行，干脆就复制了个BLEByteConv，改名BLENegativeConv，加上了处理负数。

class BLEByteConv(BaseConv):
    def decode(self, device: "XDevice", payload: dict, data: str):
        payload[self.attr] = int(data[:2], 16)  # uint8

class BLENegativeConv(BaseConv):
    def decode(self, device: "XDevice", payload: dict, data: str):
        value = int(data[:2], 16)
        if value > 0x7F: # 处理int8的16进制负数
            value = -(0xFF - value + 1)
        payload[self.attr] = value

电池电量就先不管他了，其他目前看下来还行，还在测试

嗯嗯，这个值是sint8，我猜大概是在python里面要用把这个sint8用sign extension来转换成sint64，python应该才会正确显示。直接把sint8转换到sint64，会把sint8当成uint8来使用。

负数都是最高位是sign bit，所以表示的意义不同
