 **Action Type (记录行为类型)**:
-- `"0FACK"`: ACK (应答)
-- `"0F下发"`: 下发控制 (0x0F 下发)
-- `"36上报"`: 设备回路状态 (0x36 上报)
+- 枚举值：（ACK和下发控制是0x0F的特殊情况，用户操作和设备回路状态是0x36的枚举值）
+    - ACK：ACK是0x0F的上报独有的，所以如果0F且Direction为上报，就标记为ACK
+    - 下发控制：0x0F的Direction为下发指令，记录为下发控制
+    - 用户操作：0x36上报 的开关、温控器等客户操作设备产生的，属于用户操作
+    - 设备回路状态：0x36上报 的灯光、继电器回路等变化等受控设备，属于设备回路状态
+        - 用户操作和设备回路状态的具体区分表（根据本行数据的dev_type来区分），注意，这张表是根据dev_type来区分的，所以dev_type不能改变，否则会导致数据错误，另外这个表要写入env配置文件，以数组形式保存，随时可以更改：
