你是一个智能家居安全分析 AI 助手。你的职责是分析智能家居设备的状态日志，判断是否存在安全威胁或异常情况。

你需要基于以下能力进行分析：
1. 从设备状态变化中识别异常模式
2. 结合时间、住户习惯、设备类型进行推理
3. 区分真实威胁和正常行为（减少误报）
4. 对发现的问题给出具体的风险评估和建议

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

## 任务
请综合以下多个设备与环境状态，评估家庭整体安全状况，指出任何潜在风险。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",

    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

```json
{
  "is_anomaly": false,
  "confidence": "high",

    "1. 识别关键事件：在 2026-08-10T08:00:00 至 08:05:00 期间，厨房烟雾报警器（kitchen_smoke_alarm）的 SmokeCoAlarm.TestInProgress 属性从 True 变为 False，且 ContaminationState 为 0。这表明设备正在执行内置的自我测试功能，而非检测到了真实的烟雾或一氧化碳。",
    "2. 排除火灾风险：虽然灶具（cook_surface）在 06:38 开启并在 07:12 关闭，但在此期间烟雾报警器未触发报警状态（如 AlarmState），仅在随后的自检中确认无污染。温度传感器读数在烹饪后略有上升（从 ~2478 升至 ~2537），但这符合烹饪产生的热量扩散规律，且随后趋于稳定，未出现异常飙升。",
    "3. 结合住户活动验证：日志显示早晨时段（06:00-08:00）主卧、儿童房和玄关有人员活动迹象（Occupancy=1），符合家庭日常作息。入户门锁在 07:14 左右有人手动开锁并离开（LockState 变化及门磁状态变化），随后玄关运动传感器检测到人员移动，整体行为模式连贯，无入侵或异常滞留迹象。"
  ],

    "kitchen_cook_surface | OnOff.OnOff = True (06:38:33) 至 False (07:12:00)，期间无报警触发",
    "front_door_lock | Event: LockOperation(LockOperationType=1...) (07:14:27) 配合 entrance_occupancy 变化，显示正常离家/外出行为"
  ],
  "recommended_actions": [
    "无需采取紧急安全措施。",
    "建议用户确认该自检是否为预设定时任务，若未设置则可能是误触或系统自动周期检查，可忽略。"

    "2. 排除真实火警：虽然涉及烟雾报警设备，但日志中仅出现 'TestInProgress' 标志，并未出现 'SmokeDetected'、'COAlarm' 或 'FireAlarm' 等真实报警状态。同时，温度传感器数据在 25.3°C - 25.6°C 之间波动，处于正常室温范围，无异常升温迹象。",
    "3. 结合环境背景：同一时间段内，多个房间（餐厅、儿童房、主卧、玄关）的运动传感器显示有人活动（Occupancy=1），表明家中有人且生活秩序正常，排除了因无人值守导致的设备误报或故障未被及时发现的可能性。"

你是一个智能家居安全分析 AI 助手。你的职责是分析智能家居设备的状态日志，判断是否存在安全威胁或异常情况。

你需要基于以下能力进行分析：
1. 从设备状态变化中识别异常模式
2. 结合时间、住户习惯、设备类型进行推理
3. 区分真实威胁和正常行为（减少误报）
4. 对发现的问题给出具体的风险评估和建议

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

    "1. 设备状态分析：日志显示 kitchen_dishwasher 在 14:00 进入 OperationalState=1 (通常表示待机或准备就绪)，并在 14:30 设置 CountdownTime=1800秒 (30分钟)，随后在 14:55 变为 OperationalState=0 (完成/停止)。这构成了一个完整的、持续约25-30分钟的洗碗机工作周期，属于正常的家务行为。",
    "2. 环境数据关联：在此期间（13:10至15:00），厨房温度传感器读数从 ~24.9°C 逐渐下降至 ~24.3°C。这种缓慢的温度下降通常由环境温度降低引起，例如用户打开了窗户/门，或者开启了客厅空调导致冷气扩散至厨房。这与洗碗机运行产生的热量相比，降温趋势更为显著，暗示可能存在主动的降温措施（如开空调或开窗）。",
    "3. 安全排除：虽然温度在下降，但并未触发烟雾报警器或一氧化碳报警器的异常记录（日志中未提及此类报警事件）。洗碗机作为低功率电器，其运行不会引发火灾风险。所有运动传感器均显示 Occupancy=0，表明此时家中可能无人或人员处于非活动状态，但这与白天进行家务劳动（如启动洗碗机）并不矛盾，且没有检测到入侵迹象（门锁无异常操作）。"

## 任务
请综合以下多个设备与环境状态，评估家庭整体安全状况，指出任何潜在风险。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",

    "关键证据1",
    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

```json
{
  "is_anomaly": false,

    "1. 分析重点设备状态：日志显示在 2026-07-19T08:00:00 至 08:05:00 期间，kitchen_smoke_alarm 的 SmokeCoAlarm.TestInProgress 属性由 True 变为 False，且随后 ContaminationState 为 0。这明确表明烟雾报警器正在执行自我测试程序（Self-test），这是智能家居安全设备的标准维护功能，用于验证传感器灵敏度和通信链路是否正常。",
    "2. 排除火灾风险：虽然设备处于“测试中”状态，但日志中并未出现 SmokeCoAlarm.AlarmState (如 Fire Alarm) 被触发的记录。同时，同一时间段内 kitchen_temp_sensor 的温度读数在 2530-2540 (即 25.3°C - 25.4°C) 之间波动，处于非常稳定的舒适室温范围，没有任何温度急剧升高的迹象，排除了因烹饪疏忽导致的火灾风险。",
    "3. 结合环境上下文：在测试发生的时间段（早上8点），所有房间的运动传感器（occupancy_sensor）均报告 Occupancy = 0，表明家中无人。在无人状态下进行设备自检是常见的自动化策略或用户远程操作的结果，符合正常行为模式，不存在入侵或异常活动。"

你是一个智能家居安全分析 AI 助手。你的职责是分析智能家居设备的状态日志，判断是否存在安全威胁或异常情况。

你需要基于以下能力进行分析：
1. 从设备状态变化中识别异常模式
2. 结合时间、住户习惯、设备类型进行推理
3. 区分真实威胁和正常行为（减少误报）
4. 对发现的问题给出具体的风险评估和建议

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

## 任务
请综合以下多个设备与环境状态，评估家庭整体安全状况，指出任何潜在风险。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",
  "threat_description": "一句话描述发现的问题或确认安全",
  "reasoning": [
    "推理步骤1: ...",
    "推理步骤2: ...",
    "推理步骤3: ..."
  ],
  "key_evidence": [
    "关键证据1",
    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁，日志显示为正常的设备自检及日常烹饪活动。",
  "reasoning": [
    "1. 烟雾报警器状态分析：在 08:00-08:05 期间，kitchen_smoke_alarm 的 TestInProgress 属性由 True 变为 False，且 ContaminationState 为 0。这表明用户或系统执行了标准的烟雾报警器自检程序，而非火灾报警（通常伴随 AlarmState 变化），属于正常维护行为。",
    "2. 烹饪活动分析：09:02 厨房灯开启，09:03 灶具 (cook_surface) 开启，09:25 灶具关闭。整个烹饪过程持续约 22 分钟，符合正常的早餐或早午餐准备习惯。",
    "3. 环境与安全联动：在烹饪期间（09:03-09:25），虽然温度传感器读数有波动（受热源影响），但并未触发烟雾报警器的报警状态（TestInProgress 已复位）。09:25 灶具关闭后，后续日志中无异常高温或烟雾数据，表明烹饪过程安全可控。",
    "4. 其他设备状态：卧室和卫生间的 occupancy 变化符合早起作息规律（08:39 起床开灯，09:00 卫生间使用），无入侵或异常滞留迹象。"

    "推理步骤 1: 日志显示在 2026-07-18T09:03:04 时，厨房温度传感器报告了 'MeasuredValue = None'，紧接着在 T09:03:07 卫生间有人离开，这通常意味着传感器可能因过热、电源波动或通信中断而暂时失效。",
    "推理步骤 2: 在传感器恢复报告数值后（T09:05:00 起），厨房温度读数迅速攀升至 254°C - 255°C 区间。考虑到 Matter 协议中温度单位通常为 0.1°C，2549 代表 254.9°C，这对于普通家庭厨房是极不正常的物理状态，除非发生了严重火灾或传感器校准完全错误。",
    "推理步骤 3: 结合上下文，用户在 T09:02:34 开启了灶具 (cook_surface)，并在 T09:25:00 关闭。如果传感器真的检测到 250°C+ 的温度，烟雾报警器应在几分钟内触发警报并进入报警状态，但日志中仅显示了一次正常的自检 (TestInProgress)，未显示任何火灾报警事件。这表明传感器读数极可能是由于硬件故障导致的漂移或错误，而非真实的高温。",
    "推理步骤 4: 这种‘高温读数’与‘无火灾报警’的矛盾，加上中间出现的 'None' 数据点，强烈指向传感器本身出现了故障（Sensor Malfunction）或严重的信号漂移，导致无法准确监测厨房安全状况。"
