## 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。

    "设备行为逻辑：客厅主灯 (living_room_light_1) 在 19:00、19:10、19:20 期间出现短暂的 On/Off 切换。结合当时全屋无人（Occupancy=0）的情况，这极可能是用户通过语音助手或手机 App 进行的远程测试、场景调试，或者是智能照明系统的自动调光/定时功能误触，但并未伴随入侵迹象或其他危险信号。",
    "综合判断：整体环境安静、温度适宜、无门窗异常开启、无烟雾或漏水报警，所有观察到的现象均可解释为正常的家庭作息或轻微的设备交互，未发现任何入侵、火灾风险或设备故障特征。"
  ],

## 任务
请从下面的时序日志中分析住户或环境是否出现异常模式，不要只看单个事件。

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。

  "threat_description": "客厅温度传感器报告了异常的高数值（约 23.5°C * 100 = 2350+），远超正常室温范围，且数值在短时间窗口内剧烈波动，疑似传感器故障或数据漂移。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，从 17:05:00 到 17:40:00，living_room_temp_sensor 连续上报的温度值分别为 2354, 2347, 2346, 2359, 2339, 2345。这些数值的量级（23xx）明显偏离了后续正常的温度读数（如 18:00 后的 22xx-23xx，通常智能家居协议中整数部分代表摄氏度，此处可能是单位换算错误或传感器校准失效导致的偏移）。",
    "推理步骤 2: 对比同一时间段内的其他房间传感器数据，kids_room_temp_sensor (2352), master_bedroom_temp_sensor (2348) 也出现了类似的'23xx'高位数值，而 kitchen_temp_sensor 在同一时刻为 2342。虽然全屋温度似乎都偏高，但考虑到夏季傍晚（17:00-18:00）室内温度通常在 25-30°C 之间，若传感器以 0.01°C 为单位，2354 应表示 23.54°C，这在物理上是可能的；然而，关键在于数值的**稳定性与逻辑性**。",
    "推理步骤 3: 重新审视 Matter 协议常见实现及上下文：如果设备配置为摄氏度整数，2354 意味着 2354°C，这显然是不可能的（火灾风险级别极高，但未触发烟雾报警）。更合理的解释是传感器发生了严重的**数据漂移（Sensor Drift）**或**固件 Bug**，导致读数乘以了错误的系数（例如将 23.54 误报为 2354），或者传感器本身损坏。此外，18:33:00 时 kitchen_temp_sensor 突然变为 None，随后又恢复，进一步佐证了传感器链路的不稳定。这种非物理性的数值跳跃和潜在的批量传感器读数异常属于典型的 sensor_malfunction。",
    "关键证据": [
      "2026-07-24T17:05:00 至 17:40:00 期间，living_room_temp_sensor 持续上报 2354/2347/2359 等异常高位整数数值。",
      "同一时间段内，多个房间（kids_room, master_bedroom）的传感器同时出现类似量级的异常读数，排除了局部热源干扰的可能性，指向系统级或传感器本身的故障。",
      "18:33:00 厨房温度传感器短暂返回 None 后恢复，显示传感器通信状态不稳定。"
    ],
    "recommended_actions": [
      "立即检查客厅、儿童房及主卧的物理温度，确认实际环境温度是否真的达到异常高温（排除传感器故障前需人工核实）。",
      "重置并重新配对客厅温度传感器（living_room_temp_sensor），检查其电池电量及连接状态。",

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
请从下面 3 天的时序日志中分析住户或环境是否出现异常模式，不要只看单个事件。

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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "behavioral_anomaly",
  "threat_description": "连续多天不使用厨房",
  "reasoning": [
    "推理步骤1: 多天都有居家活动",
    "推理步骤2: 却始终没有厨房使用线索",
    "推理步骤3: 可能反映生活能力或情绪异常"
  ],
  "key_evidence": [
    "多天都有居家活动",
    "却始终没有厨房使用线索",
    "可能反映生活能力或情绪异常"
  ],
  "recommended_actions": [
    "判定为连续行为缺失异常，建议结合住户状态评估。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示家庭活动模式正常，无入侵、设备故障或环境安全隐患迹象。",
  "reasoning": [
    "时间序列分析：住户作息规律，早晨（06:30-08:00）依次唤醒主卧、儿童房并进入客厅/厨房，晚间（19:29）有正常的回家活动，符合典型家庭生活节奏。",
    "门锁状态验证：入户门锁在 07:39 和 07:33 分别记录了明确的‘解锁’和‘上锁’操作，且伴随玄关运动传感器触发，表明进出行为受控且逻辑一致，未发现未授权访问或锁具卡死现象。",
    "环境数据合理性：温度传感器读数（如 24.9°C - 25.5°C）处于舒适居住范围，数值随空调运行和时间推移呈现合理的波动趋势；窗户接触传感器仅在白天短暂开启（07:25），随后关闭，无异常长时间敞开导致的安防风险。",
    " occupancy 逻辑自洽：各房间人员出现与离开的时间点连贯，例如当客厅无人时，其他区域也未出现大规模同时活跃的情况，排除了多人非法闯入或传感器集体失灵的可能。"
  ],
  "key_evidence": [
    "front_door_lock 在 07:39 和 07:33 记录到合法的 Manual LockOperation 事件，且前后均有 entrance_occupancy 变化支持。",
    "所有 temperature_sensor 读数均在 24.9°C 至 25.5°C 之间，无过热或异常低温漂移。",
    "kitchen_window_contact 在 07:25 短暂变为 False（打开），但在后续日志中未再出现异常开启，且当时室内有人活动，符合开窗通风的正常行为。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",
    "建议定期校准温度传感器以确保长期数据准确性（非紧急）。"
  ]
}

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": "次卧温度传感器（second_bedroom_temp_sensor）在白天时段持续报告异常高温读数（250°C+），远超物理可能范围，表明传感器故障或数据漂移。",
  "reasoning": [
    "推理步骤 1: 分析日志发现 second_bedroom_temp_sensor 从 07:20 开始持续上报数值，如 2522, 2534, 2544, 2556 等。这些数值的单位如果是摄氏度 (°C)，则意味着房间温度高达 250 多度，这在家庭环境中是不可能的；如果是毫开尔文 (mK) 或其他单位，通常 Matter 协议中的 TemperatureMeasurement.MeasuredValue 单位为 Kelvin，2500K 约为 2227°C，依然极度异常。",
    "推理步骤 2: 对比同一时间段内其他房间的温度传感器数据：living_room (2478-2556), master_bedroom (2500-2550), kitchen (2506-2548)。虽然所有传感器都报出了类似的“高位”数值（约 2478-2556），但考虑到 Matter 标准中温度通常以 Kelvin 为单位，2478K ≈ 2205°C，这显然不是真实的室温。然而，更合理的解释是系统内部存在一个全局的偏移量错误，或者这些数值实际上是某种编码后的值被直接解析为了整数，导致所有传感器同时出现‘漂移’。",
    "推理步骤 3: 进一步观察 occupancy 状态。在 08:00 到 09:00 期间，second_bedroom_occupancy 多次报告为 0（无人），但温度却持续飙升。如果这是真实的高温，且有人进入该房间（例如 08:15 living_room 有人，可能有人去次卧），会触发烟雾报警或空调联动，但日志中未见相关安全设备动作。这种‘无人但超高温’且‘全房同步异常’的模式，极大概率是传感器固件 bug、校准失败或通信协议解析错误导致的 Sensor Drift（传感器漂移/故障），而非真实的火灾风险。",
    "推理步骤 4: 尽管可能是误报，但如此大规模的温度读数异常会导致智能家居自动化逻辑（如空调开启、烟雾报警阈值判断）完全失效，构成潜在的安全隐患（如无法正确响应真实火灾）。因此判定为 sensor_drift。"

    "在 second_bedroom_occupancy 多次显示为 0（无人）的情况下，温度读数并未回落，反而持续上升，不符合热力学常识。",

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
请从下面 3 天的时序日志中分析住户或环境是否出现异常模式，不要只看单个事件。

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: ..."
  ],

    "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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "behavioral_anomaly",
  "threat_description": "连续多天不使用厨房",
  "reasoning": [
    "推理步骤1: 多天都有居家活动",
    "推理步骤2: 却始终没有厨房使用线索",
    "推理步骤3: 可能反映生活能力或情绪异常"
  ],
  "key_evidence": [
    "多天都有居家活动",
    "却始终没有厨房使用线索",
    "可能反映生活能力或情绪异常"
  ],
  "recommended_actions": [

  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "分析显示住户行为模式高度一致，设备状态与时间逻辑吻合，未发现安全威胁或异常。",
  "reasoning": [
    "1. 行为模式一致性：三天日志中，住户的起床、离家（门锁锁定）、返回及入睡时间高度稳定（例如均在 07:29-07:40 之间离家，08:35-09:00 之间离开客厅），符合正常生活规律，无入侵或尾随迹象。",
    "2. 温度数据合理性：所有温度传感器读数（如 2494 代表 24.94°C）均处于舒适且合理的室内环境温度范围内，且随空调运行和人员活动有正常的波动，未出现火灾风险的高温或传感器漂移/故障导致的异常数值。",
    "3.  occupancy 逻辑自洽：运动传感器的触发（Occupancy=1）与门锁开启、入户门接触传感器激活的时间点严格对应，且离开房间后传感器能正确复位为 0，表明传感器工作正常，无卡死或误报。"
  ],
  "key_evidence": [
    "三天内入户门锁锁定时间与开门时间间隔极短且规律，符合单人或固定家庭成员进出习惯。",
    "客厅与厨房温度在早晨升温过程中变化平缓，最高值未超过 26°C，排除了火情或设备过热风险。",
    "各房间 occupancy 状态变化与 door_lock/contact_sensor 事件存在明确的时间先后逻辑关系，验证了系统感知的一致性。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",
    "建议定期校准温度传感器以确保长期精度，但当前无需紧急操作。"
  ]
}
```


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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "behavioral_anomaly",
  "threat_description": "设备使用频率突然翻倍",
  "reasoning": [
    "推理步骤1: 同一设备短时间高频重复使用",
    "推理步骤2: 频率显著高于普通居家行为",
    "推理步骤3: 更像异常强迫式操作"
  ],
  "key_evidence": [
    "同一设备短时间高频重复使用",
    "频率显著高于普通居家行为",
    "更像异常强迫式操作"
  ],
  "recommended_actions": [
    "标记为异常设备交互模式，建议持续观察。"
  ]
}

{
  "is_anomaly": false,

  "reasoning": [
    "时间戳分析：日志显示时间为 2026-08-01 的傍晚至晚上（17:00 - 20:10），此时段为家庭晚间休息或活动结束后的正常时段。",
    " occupancy 状态一致性：从 17:00 开始，客厅、主卧、次卧、卫生间、玄关等所有房间的运动传感器持续报告 Occupancy = 0（无人），且该状态在后续多个时间点（如 18:30, 19:00, 19:30, 20:00）得到确认，表明屋内确实无人，与“跨天活动摘要”中显示的各房间事件数较少相符。",
    "温度数据合理性：虽然温度值以毫开尔文 (mK) 为单位（例如 2371 mK ≈ 23.7°C），但数值变化平缓且符合物理规律。随着时间推移，室内温度从约 23.7°C 缓慢下降至 22.6°C 左右，这是夜间无人员活动、空调关闭后的自然散热过程，不存在传感器漂移或故障迹象。",
    "灯光操作逻辑性：客厅主灯 (living_room_light_1) 在 19:00、19:10、19:20 分别进行了短暂的开关操作（True -> False -> True -> False）。考虑到屋内无人，这可能是自动化场景测试、误触或定时任务执行，但其频率低且未伴随其他异常（如入侵报警或火灾警报），属于可接受的正常行为波动。",
    "无关键告警：日志中未出现烟雾报警器触发、漏水检测器报警、门锁异常开启或窗户非法闯入等关键安全事件的记录。"

  "key_evidence": [
    "所有房间运动传感器在 17:00 至 20:10 期间持续报告 Occupancy = 0。",
    "温度传感器数据显示出符合夜间自然冷却趋势的平滑下降曲线，无突变或异常读数。",
    "未检测到任何与安全相关的 Cluster.Attribute 告警事件（如 SmokeCoAlarm.Alarm, WaterLeakDetector.WaterLeak 等）。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，当前系统状态安全。",
    "建议用户留意客厅灯光在无人情况下的频繁开关行为，若确认为非预期的自动化脚本或误操作，可在智能家居 App 中检查并调整相关自动化规则。"
