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。

{
  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "当前日志更符合正常模式，不建议报警。",
  "reasoning": [
    "推理步骤1: 正常样本是一两次失败后由成人成功开门；异常样本是短时连续失败尝试。"
  ],
  "key_evidence": [
    "正常样本是一两次失败后由成人成功开门；异常样本是短时连续失败尝试。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "儿童房温度传感器读数异常（约 23.9°C 显示为 2396），且数值随时间持续下降，表明传感器可能故障或数据漂移，导致无法准确监控儿童房环境安全。",
  "reasoning": [
    "推理步骤 1: 分析日志发现 kids_room_temp_sensor 在 16:10 至 17:00 期间报告的温度值分别为 2396, 2390, 2378... 等。这些数值远超正常室温范围（通常 18-30°C），且呈现明显的线性递减趋势，不符合真实物理环境的波动规律。",
    "推理步骤 2: 对比同一时间段内其他房间（如 master_bedroom, kitchen, living_room）的温度传感器读数，均在 2340-2360 之间合理波动，证明家庭整体环境温度正常，排除了全屋过热或系统基准错误的可能性。",
    "推理步骤 3: 结合 occupancy_sensor 显示儿童房内有人（Occupancy=1），如果温度传感器正常工作，应能反映人体散热导致的微升温或稳定状态，而非出现高达 2396 的荒谬数值并持续下降。这种‘高值 + 单调下降’的模式是典型的传感器校准失败、固件 Bug 或通信干扰导致的 Sensor Drift/Malfunction。"
  ],
  "key_evidence": [
    "kids_room_temp_sensor 连续报告数值 > 2300 (e.g., 2396, 2390)，远超物理极限。",
    "该数值随时间推移呈现非自然的线性下降趋势 (2396 -> 2358 -> 2330)。",
    "同期其他房间温度传感器读数正常 (2300-2360 区间)，形成鲜明对比。"
  ],
  "recommended_actions": [
    "立即检查儿童房温度传感器的硬件连接及供电情况。",
    "尝试重启设备或重新配对以重置传感器校准。",
    "在修复前，建议家长人工定期监测儿童房实际温度，以防因误报导致空调/暖气失控或真实高温未被察觉。",
    "联系设备制造商获取固件更新或技术支持，排查是否存在已知 Bug。"

## 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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁，日志显示为正常的家庭晚间活动模式。",
  "reasoning": [
    "1. 烹饪行为分析：厨房灶具（kitchen_cook_surface）在 07:10 和 18:33/19:01 开启，均伴随厨房灯（kitchen_light）的开启或保持开启状态，且时间符合早餐和晚餐时段。未发现灶具长时间无人看管（unattended cooking）的迹象，因为每次开启后不久都有其他房间（如客厅、主卧）的人员活动记录，暗示有人在家并可能经过厨房区域。",
    "2. 人员活动一致性：入户门传感器在 18:02 触发手动开锁，随后玄关、客厅、餐厅等公共区域运动传感器相继激活，符合家庭成员下班回家回家的正常动线。儿童房和主卧的运动传感器在晚间持续有活动记录，表明住户在家且状态正常。",
    "3. 环境数据合理性：温度传感器读数（如 2264-2361，推测单位为 0.1°C 即 22.6-23.6°C）处于舒适区间，无剧烈波动或异常高温（排除火灾风险）。门窗传感器状态正常，无非法入侵迹象。"
  ],
  "key_evidence": [
    "kitchen_cook_surface 开启时间与 kitchen_light 开启时间重合，且发生在常规用餐时段 (07:10, 18:33)。",
    "18:02 入户门锁手动解锁后，entrance_occupancy 和 living_room_occupancy 随即被触发，形成完整的回家行为链。",
    "全屋多个房间（kids_room, master_bedroom, living_room）在晚间均有 occupancy_sensor 活动，证明家中有人照看。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续保持当前的自动化规则监控，确保灶具超时自动关闭功能已启用以作为双重保障。"
  ]
}
```

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "儿童房温度传感器数据严重异常，读数高达 2359°C，远超物理可能范围，表明传感器故障或信号干扰。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，在 2026-08-21T17:00:00 至 17:50:00 期间，kids_room_temp_sensor 报告的温度值在 2347 到 2361 之间波动。",
    "推理步骤 2: 对比同一时间段内其他房间（如 living_room、master_bedroom）的温度传感器读数，均在正常的 22°C - 23°C 范围内（例如 2328, 2329）。",
    "推理步骤 3: 考虑到 Matter 协议中温度通常以 0.01°C 为单位存储，2359 的数值极有可能是传感器硬件故障、固件错误导致的数据溢出，或者是被恶意攻击篡改的信号，而非真实的室温。这种极端高温若被误判为真实环境，可能导致空调系统无效运行或触发错误的火灾报警逻辑。",
    "推理步骤 4: 尽管该时段儿童房有人员活动（occupancy=1），但如此高的温度读数与人体存在及周围正常室温完全不符，确认为设备层面的异常。"
  ],
  "key_evidence": [
    "2026-08-21T17:00:00 kids_room_temp_sensor 报告 MeasuredValue = 2359 (单位应为 0.01°C，即 23.59°C? 不，结合上下文 2328 代表 23.28°C，则 2359 代表 235.9°C 或数据位错误，无论如何均异常)",
    "同期 living_room_temp_sensor 和 master_bedroom_temp_sensor 读数稳定在 2300-2330 区间，显示环境正常",
    "温度读数在数小时内持续维持在 2300+ 的高位，未随时间自然下降，符合传感器死锁特征"
  ],
  "recommended_actions": [
    "立即检查并重置儿童房温度传感器设备，确认其硬件状态。",

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。

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。

    "2. 门锁与门禁状态：16:09 入户门被手动解锁并打开（LockState=2, Contact=False），随后儿童房灯光开启。结合此时段其他房间有人活动的情况，这极有可能是家长回家或孩子在屋内移动导致的正常开门/开灯行为，未发现异常闯入迹象。",

## 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，日志显示为正常的家庭晚间活动及烹饪行为。",
  "reasoning": [
    "1. 烹饪行为分析：厨房灶具 (kitchen_cook_surface) 在 07:06-07:30 和 18:30-19:15 开启，时间符合早餐和晚餐习惯。每次使用后均有明确的关闭记录（OnOff=False），且持续时间合理（约24分钟和45分钟），未发现长时间无人看管或异常长时开启的情况，排除 unattended_cooking 风险。",
    "2. 人员活动模式：主卧 (master_bedroom)、儿童房 (kids_room) 及公共区域 (living_room, dining_room, entrance) 的运动传感器在傍晚至夜间时段频繁触发 Occupancy=1，表明家庭成员在家中进行正常活动（如晚餐、洗漱、休息）。入户门传感器虽有多次触发，但结合室内多房间的人员存在状态，符合家庭成员归家后的正常动线，无入侵迹象。",
    "3. 设备状态与数据合理性：温度传感器读数（如 2320, 2340 等）处于合理的摄氏度范围（推测单位为0.01度或直接为整数，数值对应室温约23-24°C），无明显漂移或故障。洗碗机在 19:39 启动，符合晚餐后清洁习惯。所有关键设备状态变化逻辑连贯，无矛盾或异常停滞。"
  ],
  "key_evidence": [
    "kitchen_cook_surface 在 18:30:30 开启，19:15:00 关闭，时长约45分钟，属正常烹饪时长。",
    "master_bedroom_occupancy 和 kids_room_occupancy 在 17:00-20:15 期间持续报告 Occupancy=1，证明有人居住。",
    "entrance_occupancy 多次触发（18:04, 18:29, 18:54, 19:14, 19:39, 19:59），结合室内其他区域活跃，判定为正常人员走动而非非法入侵。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续保持当前的自动化规则监控，确保灶具超时自动关闭功能生效以作为双重保障。"
  ]
}
```

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "儿童房温度传感器报告异常数值（2356-2340），远超正常物理温度范围，表明设备故障或数据漂移。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，从 2026-08-17T17:00:00 开始，kids_room_temp_sensor 连续多次上报温度值分别为 2356, 2340, 2343, 2327, 2326, 2322 等。",
    "推理步骤 2: 这些数值的量级（2300+）明显不符合摄氏度（°C）或华氏度（°F）的物理常识（正常室温通常在 20-30°C 之间）。即使是华氏度，2356°F 也意味着房间已燃烧殆尽，这与同一时间段内其他房间（如客厅、厨房）正常的 22-23°C 读数完全矛盾。",
    "推理步骤 3: 结合上下文，该设备在后续时间点（如 19:25, 20:05）虽然数值有所下降但仍处于高位（2284, 2274），且与其他传感器数据不匹配，确认为传感器硬件故障、校准错误或通信协议解析错误导致的严重数据漂移（Sensor Drift/Malfunction）。"
  ],
  "key_evidence": [
    "2026-08-17T17:00:00 kids_room_temp_sensor 上报 MeasuredValue = 2356 (异常高)",
    "2026-08-17T18:00:00 同房间上报 2322，而同期 living_room_temp_sensor 为 2320 (单位不一致或设备故障)"
  ],
  "recommended_actions": [
    "立即检查并重置儿童房温度传感器，确认是否因电池电量不足或固件 Bug 导致。",
    "暂时忽略该传感器的报警逻辑，改用客厅或主卧的温度传感器作为儿童房环境的参考依据，直至设备修复。",
    "联系设备制造商进行固件更新或硬件更换，防止因数据错误触发误报的空调/加湿器控制逻辑。"

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": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "当前日志更符合正常模式，不建议报警。",
  "reasoning": [
    "推理步骤1: 正常样本是一两次失败后由成人成功开门；异常样本是短时连续失败尝试。"
  ],
  "key_evidence": [
    "正常样本是一两次失败后由成人成功开门；异常样本是短时连续失败尝试。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]

  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "儿童房温度传感器报告了异常的高数值（2375），远超正常物理温度范围，且随后出现数据漂移和丢失，表明传感器可能故障或被干扰。",
  "reasoning": [
    "推理步骤 1: 在 2026-08-28T16:30:00，kids_room_temp_sensor 报告温度为 2375。根据 Matter 协议标准及物理常识，该值极大概率是摄氏度单位错误（应为 23.75°C）或传感器读数溢出/故障，因为室内温度不可能达到 2375°C。",
    "推理步骤 2: 随后的几次读数（2362, 2372, 2356, 2354）虽然数值下降，但仍处于非物理合理的‘高位’区间，且与其他房间（如厨房 2352, 主卧 2344）相比，儿童房温度异常偏高，不符合热力学平衡规律。",
    "推理步骤 3: 从 18:26:00 开始，该传感器连续多次返回 None (null)，显示数据链路中断或设备彻底失效。结合之前的荒谬高值，这符合典型的传感器硬件故障、校准错误或固件崩溃模式，而非真实的环境变化。",
    "推理步骤 4: 尽管其他设备（门锁、运动传感器、其他房间温度）运行正常，但关键的安全监测设备（儿童房温控）的持续异常可能导致无法准确监控儿童房环境安全，属于设备层面的安全隐患。"

  "key_evidence": [

    "2026-08-28T18:26:00 至后续时间点 kids_room_temp_sensor 连续返回 MeasuredValue = None"
  ],
  "recommended_actions": [
    "立即检查儿童房温度传感器的物理状态，确认是否被遮挡、损坏或电池电量不足。",
