## 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: 正常样本是晚餐时间且有成人活动；异常样本发生在夜间儿童应睡时段。"
  ],
  "key_evidence": [
    "正常样本是晚餐时间且有成人活动；异常样本发生在夜间儿童应睡时段。"

{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "儿童房温度传感器报告了异常高的数值（2348-2340），远超正常物理温度范围，且与同房间其他设备状态及相邻房间温度趋势不一致，表明传感器可能故障或数据漂移。",
  "reasoning": [
    "推理步骤 1: 分析时间戳为 2026-07-20T17:20:00 至 18:00:00 期间的日志，发现 kids_room_temp_sensor 连续上报的 MeasuredValue 分别为 2348, 2346, 2340, 2330。在 Matter 协议和标准温度测量中，单位通常为摄氏度 (°C) 或毫开尔文 (mK)。若单位为 °C，234°C 对于室内环境是不可能的；若单位为 mK，则对应约 -0.15°C，但考虑到后续数值下降趋势及与其他房间对比，更可能是传感器读数错误（如溢出、校准错误或固件 Bug）导致数值虚高。",
    "推理步骤 2: 对比同一时间段内其他房间的温度数据。客厅 (living_room)、主卧 (master_bedroom)、厨房 (kitchen) 等房间的温度均在 2300-2350 之间波动（假设单位为 mK，即约 22.8°C - 23.2°C）。如果 kids_room 的 2348 是真实高温，其温差将超过 20°C，这在无特殊加热设备的儿童房内极不寻常。更重要的是，当其他房间温度稳定在 23xx 水平时，kids_room 的读数却异常偏高且随后缓慢下降，这种孤立的高值不符合热力学规律。",
    "推理步骤 3: 结合 occupancy_sensor 数据。在温度异常期间（17:20-18:00），kids_room_occupancy 显示有人存在（Occupancy=1），且 dining_room 和 living_room 也有人员活动。这表明并非无人导致的误报，而是传感器本身在有人活动时输出了错误数据。此外，该数值序列（2348 -> 2330）虽然呈下降趋势，但起始点 2348 明显偏离了家庭平均温度基线（约 2310-2320），属于典型的传感器故障或数据漂移特征。"
  ],
  "key_evidence": [
    "2026-07-20T17:20:00 至 18:00:00 期间，kids_room_temp_sensor 读数高达 2348-2330，显著高于同时段其他房间（如 master_bedroom 2314, kitchen 2315）的读数。",
    "该异常读数出现在有人员活动的时段（occupancy=1），排除了因无人导致的静态误差，指向传感器硬件或软件故障。",
    "数值 2348 若解读为摄氏度则物理上不可能，若解读为毫开尔文则与周围环境温度差异过大，不符合热平衡常识。"
  ],
  "recommended_actions": [
    "立即检查儿童房温度传感器的物理连接和供电情况，确认是否受到干扰或损坏。",
    "暂时禁用该温度传感器的数据上报，并启用备用温度监测方案（如使用空调遥控器上的温度显示作为临时参考）。",
    "联系设备制造商或技术支持进行固件更新或硬件更换，防止因数据错误触发错误的 HVAC 控制逻辑。"

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 occupancy_sensor 显示儿童房有人活动（Occupancy=1），排除了因无人导致的设备休眠或离线问题。这种单一传感器与其他同类型传感器及环境常识的巨大偏差，确认为 sensor_malfunction（传感器故障）或 sensor_drift（数据漂移），而非真实的热源威胁。"

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",
    "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": "儿童房温度传感器读数严重异常（约 2300-2350），远超物理可能范围，且伴随该房间运动传感器持续报告无人状态，存在设备故障或数据上报错误风险。",
  "reasoning": [
    "推理步骤 1: 分析日志发现 kids_room_temp_sensor 在 17:20 至 20:35 期间连续上报的温度值均在 2260 到 2355 之间。考虑到其他房间（如客厅、厨房）的温度读数正常（约 2270-2320），且符合摄氏度单位逻辑，而儿童房读数约为正常值的 10 倍，这明显超出了任何物理环境的合理温度范围（即使是极端高温也不可能达到 2300°C）。",
    "推理步骤 2: 结合 occupancy_sensor 数据，在 17:30 至 20:30 期间，kids_room_occupancy 持续报告为 0（无人）。如果儿童房内有人活动导致温度异常升高，通常会有运动传感器触发；反之，若房间确实无人，温度应趋于稳定或随室外变化，绝不可能出现如此剧烈且数值荒谬的波动。这种‘高报温’与‘无人员’的状态组合，排除了真实火灾或人为加热导致的高温可能性。",
    "推理步骤 3: 对比同一时间段内 master_bedroom_occupancy 和 kitchen_cook_surface 等设备的正常行为，确认系统整体运行正常。唯独儿童房温度传感器表现出典型的‘传感器漂移’或‘固件/通信错误’特征（例如将小数点后的数值误报为整数，或者内部寄存器溢出）。这种单一传感器的极端异常属于 sensor_malfunction，而非入侵或火灾威胁。"

## 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: ..."
  ],

    "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 19:01 开启，此时厨房灯 (kitchen_light) 已开启（19:00），且多个房间（entrance, dining_room, living_room）的运动传感器均检测到有人活动。这表明有人在厨房进行烹饪准备或正在用餐，属于正常的“有人看管”状态，不存在无人看管烹饪风险。",
    "2. **人员流动与门锁逻辑**：入户门在 18:08 被手动解锁并打开（contact_sensor=False），随后玄关和客厅运动传感器检测到人员进入，符合家庭成员下班回家的正常归家流程。没有发现非法入侵迹象。",
    "3. **儿童房安全状态**：虽然重点监控对象是儿童房，但日志中儿童房运动传感器持续显示 Occupancy=1（从17:06至19:36+），表明儿童一直在房间内活动。温度读数在22-23摄氏度左右，处于舒适范围。未发现儿童独自外出、窗户异常开启或长时间静止等异常情况。",
    "4. **设备状态一致性**：所有涉及的关键设备（灯光、传感器、家电）状态变化符合时间逻辑（如晚上开灯、回家开空调/灯）。无传感器卡死（stuck）或数据漂移导致的误报特征。"
  ],
  "key_evidence": [
    "19:01 kitchen_cook_surface OnOff=True 伴随多区域 occupancy=1，证明烹饪有人看管。",
    "18:08 front_door_lock Manual Unlock + entrance_occupancy=1，符合正常归家行为。",
    "kids_room_occupancy 在 17:06-19:36 期间持续为 1，确认儿童在房内活动。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议保持常规的安全监控策略即可。"
  ]
}
```

```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，数值高达 2300+ (应为 23-24°C)，且伴随厨房窗户意外开启事件，存在数据漂移或设备故障风险。",
  "reasoning": [
    "推理步骤 1: 分析温度数据发现，从 17:00 开始，kids_room_temp_sensor 报告的温度值在 2362 到 2267 之间剧烈波动。正常的室温应在 20-30°C 之间（即 2000-3000 的整数部分），但这里的数值如 2362、2345 等明显超出了合理范围，且后续数值持续下降至 2200 多，这不符合物理规律下的自然降温曲线，极可能是传感器读数错误（Sensor Drift/Malfunction）或单位/格式解析错误。",
    "推理步骤 2: 结合上下文，虽然厨房窗户传感器 (kitchen_window_contact) 在 18:54 报告了 'False' (开启状态)，但这通常发生在傍晚用餐时段，属于正常家庭活动。然而，如果儿童房真的处于 2362°C 的高温环境，将构成严重的火灾或健康威胁，这与家中其他区域（客厅、主卧）稳定的 22-23°C 读数形成巨大反差，进一步证实儿童房传感器数据不可信。",
    "推理步骤 3: 尽管 occupancy_sensor 显示儿童房有人，但如此离谱的温度读数无法解释为真实的热源（如有人在里面开火），最合理的推断是传感器硬件故障、校准丢失或通信干扰导致的数据漂移。这种单一传感器的极端异常若被误读，可能导致错误的警报或掩盖真实的火灾隐患。"
  ],
  "key_evidence": [
    "2026-07-28T17:00:00 至 20:00:00 期间，kids_room_temp_sensor 连续报告数值 > 2200 (例如 2362, 2345)，远超正常室温上限。",
    "同一时间段内，living_room_temp_sensor 和 master_bedroom_temp_sensor 均稳定在 2200-2300 的正常范围内，排除了全屋普遍高温的可能性。",
    "厨房窗户在 18:54 意外开启，增加了潜在的安全关注点，需确认是否为入侵尝试还是用户操作，但主要异常仍在于温度传感器的数据质量。"
  ],
  "recommended_actions": [

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",

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2: ...",

    "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，所有设备状态符合正常家庭晚间活动模式。",
  "reasoning": [
    "1. 人员活动分析：日志显示在16:10左右，儿童房（kids_room）和客厅（living_room）的运动传感器同时被触发（Occupancy=1），随后在16:30左右恢复为无人状态（Occupancy=0）。这符合家庭成员（可能是孩子或家长）在傍晚时分短暂进入房间活动的正常行为模式。",
    "2. 门窗状态分析：阳台门传感器在16:12报告状态为False（通常表示关闭/锁定），这与运动传感器触发的时间点接近，表明有人进出后关门，或者仅仅是传感器更新，没有发现非法入侵迹象（如门锁异常开启或窗户长时间未关）。",
    "3. 环境数据一致性：温度传感器读数在合理范围内波动（约23-24摄氏度），且各房间温度变化趋势一致，没有出现突变的极端值，排除了传感器故障或火灾风险。",
    "4. 无其他危险信号：厨房、卫生间等关键区域的漏水、烟雾传感器均无报警记录，入户门锁无异常操作记录。"
