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
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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。

Chosen response:

  "threat_description": "设备使用频率突然翻倍",
  "reasoning": [

    "频率显著高于普通居家行为",
    "更像异常强迫式操作"
  ],

  ]
}

Rejected response:

  "threat_description": "日志显示正常的家庭晚间活动模式，无安全威胁或异常行为。",
  "reasoning": [
    "时间线分析：事件发生在傍晚至晚上（17:00 - 20:15），符合典型的下班回家、做饭、休息的家庭作息规律。",
    " occupancy 逻辑验证：客厅 (living_room) 在 17:30 短暂无人后，于 18:13 检测到有人进入，随后与厨房、餐厅、儿童房等多房间传感器同时报告有人状态，表明家庭成员正常在屋内移动和互动，不存在长时间无人却设备频繁动作的异常情况。",
    "设备联动合理性：用户在 18:40 开启灶具，18:56 关闭；19:47 启动洗碗机。这些操作均伴随相应的照明变化（如厨房灯开启）和温度波动，且后续有人员离开该区域（如 19:56 餐厅有人，但厨房未再报动作），符合正常烹饪流程。",
    "环境数据一致性：室内温度从 23.6°C 逐渐下降至 22.5°C 左右，空调系统（SystemMode=3，通常为制冷）在 17:43 启动，随后温度稳步下降，传感器读数稳定，无漂移或故障迹象。窗户接触传感器在 19:36 变为 False（打开），但在同一时间段内多个房间仍有人活动，且未触发入侵警报，结合上下文更可能是住户开窗通风而非非法入侵。",
    "无危险信号：烟雾报警器、漏水传感器等安全设备未在日志中报告异常状态，所有 actuator（执行器）动作均有明确的 user-initiated 前因（如手动开灯、开关电器）。"
  ],
  "key_evidence": [
    "多房间 occupancy_sensor 在晚间时段呈现连续且合理的有人/有人移动模式。",

    "温度传感器数据显示空调运行后室温自然下降，无突变或停滞。",
    "窗户传感器状态变化（False）发生时，其他区域仍有正常人员活动，未伴随门锁异常或紧急报警。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，当前系统运行正常。",
    "建议定期查看完整日志以确认窗户开启事件的持续时长，确保非长期未关窗导致的能源浪费或潜在风险。"

## 任务
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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": [

    "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。

  "reasoning": [
    "推理步骤 1: 分析厨房温度传感器日志，发现从 19:05 开始，读数从正常的 24°C (2419mK) 急剧上升至 26.0°C (2601mK)，并在 19:10 达到 24.9°C (2494mK)。虽然夏季高温可能导致升温，但随后在开启灶具后数值继续非理性飙升。",
    "推理步骤 2: 关键异常点出现在 19:15-19:20。当用户开启厨房灯和灶具时，温度读数瞬间飙升至 25.53°C (2553mK) 和 26.01°C (2601mK)。考虑到 Matter 协议中温度通常以毫开尔文 (mK) 为单位，2601mK 约等于 -272.15°C（绝对零度附近），这在物理上是不可能的；或者即使单位是摄氏度，该数值也远超任何室内环境或正常烹饪产生的温度。",
    "推理步骤 3: 最致命的证据是 19:16:00 的日志显示 `kitchen_temp_sensor` 值为 `None`。这表明传感器在尝试报告极端异常值后立即失效或通信中断。结合之前不合理的数值跳变，这符合典型的传感器硬件故障、校准错误或无线信号被强干扰的特征，而非真实的火灾风险（因为烟雾报警器未触发且无其他火情迹象）。",
    "推理步骤 4: 排除误报：客厅和卧室的温度变化趋势相对平稳且符合空调运行逻辑，唯独厨房传感器表现出独立的、违背物理规律的剧烈波动和断连，确认问题局限于该特定传感器。"

System:
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。

  "threat_description": "厨房温度传感器数据严重异常，数值远超物理可能范围且出现断连，疑似设备故障或遭受干扰。",
  "reasoning": [
    "推理步骤 1: 分析厨房温度传感器日志，发现从 18:05 开始，读数急剧上升至 2448、2507、2586 直至 2709。考虑到 Matter 协议中温度通常以 0.01°C 为单位（即 23.5°C 表示为 2350），该数值对应约 27°C，看似正常；但结合上下文，若单位为毫开尔文或其他未明确标度的原始值，或者更可能的情况是：如果这是摄氏度直接记录，2709°C 会导致房屋瞬间气化，显然不可能。即使假设单位是 0.01°C，2709 代表 27.09°C，这在烹饪时是合理的。然而，关键在于 18:58 的读数突然变为 'None'，紧接着 18:57 开启了灶具。",
    "重新校准推理：让我们再次检查数值的量级。如果 2388 代表 23.88°C，那么 2709 代表 27.09°C。这是一个非常正常的烹饪温度。但是，请注意 18:58 的 `kitchen_temp_sensor` 报告了 `None` (Null)，而就在前一分钟 (18:57) 用户打开了灶具 (`cook_surface`)。随后在 19:00 读数恢复为 2534 (25.34°C)。",
    "关键矛盾点：虽然 27°C 本身不危险，但传感器在开启热源后仅 1 分钟内就返回 `None` (丢失连接或无数据)，随后又跳变回一个相对稳定的高温值，这种“断连 - 恢复”的模式在持续加热过程中极不寻常。更严重的隐患在于：如果传感器逻辑错误地将单位搞错（例如将 0.01°C 当作 1°C 读取，或者反之），或者传感器本身发生了漂移/故障导致读数不可信。",
    "修正后的深度推理：仔细观察时间线。18:57 开启灶具。18:58 温度读数为 None。19:00 温度为 2534 (25.34°C)。如果传感器正常工作，开启灶具后温度应缓慢上升。这里没有明显的过热报警。但是，**真正的异常在于数据的连续性和有效性**。在 18:58 这一关键时间点（刚开火），传感器失效（None）。这可能导致无法监控潜在的火灾风险（如油锅起火初期温度飙升过快）。此外，对比卧室和客厅的温度，它们都在 22-23°C 左右波动稳定，唯独厨房在开火前后表现出数据缺失和不稳定性。",
    "最终判定：虽然绝对温度值（~27°C）看起来不高，但传感器在操作期间（开火瞬间）的数据丢失（Sensor Malfunction/Data Loss）构成了安全隐患，因为它剥夺了系统对潜在火灾风险的实时监控能力。同时，数值的剧烈跳变（从 2709 到 None 再到 2534）也暗示了传感器可能处于不稳定状态或存在校准漂移。"

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
以下是过去一段时间的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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",

}
```

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。

    "推理步骤 3: 结合设备状态，灶具处于开启状态 (OnOff=True)，而温度读数高达 260°C+，这极可能意味着发生了燃气泄漏引发的燃烧、油锅起火导致的热辐射异常，或者是传感器本身因靠近火源/故障而报告了错误的高危数值。无论哪种情况，都构成了即时的火灾隐患。"

System:
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
以下是过去一段时间的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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",

    "关键证据2"
  ],
  "recommended_actions": [

}
```

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。
