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: ..."
  ],

    "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:

  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常情况，日志显示为独居老人在清晨正常的起床、洗漱及短暂外出活动。",
  "reasoning": [
    "1. **活动时间与行为模式分析**：日志时间集中在 04:40 至 07:05，属于清晨时段。住户在 05:32 卧室有人，随后 05:41 卫生间有人并开灯，05:50 厨房灶具开启，这符合老人早起洗漱、准备早餐或简单烹饪的正常生活规律。",
    "2. **设备状态逻辑自洽**：厨房灶具 (cook_surface) 在 05:50 开启，06:29 关闭，持续时间约 40 分钟，且期间有人员活动（厨房运动传感器多次触发），并非无人看管的长时间烹饪，排除了火灾风险。",
    "3. **门锁操作正常**：06:54 左右，入户门锁经历了 'Lock' (锁定) -> 'Unlock' (解锁) 的操作序列，且伴随门磁状态变化。结合 06:54:08 玄关运动传感器被触发，这表明住户可能进行了短暂的出门检查（如取快递、扔垃圾）或调整门锁，随后立即返回或确认安全，属于正常行为。",
    "4. **无异常环境数据**：温度传感器读数在合理范围内波动（客厅约 24-25°C），无烟雾报警或漏水报警触发。所有传感器状态变化均有对应的人员活动或设备操作支撑，未发现传感器卡死或漂移迹象。"
  ],
  "key_evidence": [
    "05:41 bathroom_occupancy = 1 且 bathroom_light = True，表明有人使用卫生间。",
    "05:50 kitchen_cook_surface = True 持续至 06:29 关闭，期间有厨房人员活动，属正常烹饪行为。",
    "06:54 front_door_lock 发生手动锁定和解锁操作，且伴随 entrance_occupancy 触发，符合短时外出或检查门锁的行为特征。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议保持现有监控配置，若此类清晨短时外出频繁，可考虑设置‘晨间活动’自动化规则以优化能源管理。"
  ]
}
```

Rejected response:

## 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",

  ],
  "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。

  "threat_description": "客厅温度传感器读数严重异常（约 24°C x 10），远超物理可能范围，且伴随厨房传感器数据丢失，表明存在严重的传感器故障或通信错误。",
  "reasoning": [
    "推理步骤 1: 分析日志发现 living_room_temp_sensor 在凌晨至清晨时段持续报告数值在 2424 到 2511 之间。考虑到 Matter 协议中温度通常以 0.01°C 为单位，该数值实际代表约 24.24°C 至 25.11°C，这在物理上是合理的室温；然而，若系统配置为整数单位（即直接代表摄氏度），则意味着室内温度高达 2400°C+，这显然不可能。结合上下文其他设备（如卧室 2367->23.67°C）的数值量级一致性判断，这里极有可能是**传感器固件 Bug、校准错误导致数值偏移了 100 倍，或者数据包解析错误**。",
    "推理步骤 2: 进一步观察 kitchen_temp_sensor，在 06:01:03 和 06:33:00 两次关键时间点（灶具开启前后）报告 `MeasuredValue = None`。对于独居老人家庭，烹饪时温度传感器失效会导致无法监控过热风险，属于安全隐患。",
    "推理步骤 3: 综合来看，虽然住户的活动模式（起床、洗漱、做饭、出门）符合正常逻辑，但核心环境感知设备（温度传感器）的数据质量完全不可信。这种大规模的数据异常（全房间温度读数畸变或丢失）不是单一事件，而是系统性故障，必须被标记为 sensor_malfunction 而非忽略。",
    "推理步骤 4: 尽管没有直接的入侵或火灾证据，但错误的温度读数可能导致空调误判（例如在高温读数下关闭制冷，或在低温读数下过度制冷），进而影响独居老人的居住安全和健康。"

  "key_evidence": [
    "living_room_temp_sensor 连续报告数值 >2400 (e.g., 2424, 2511)，若单位为摄氏度则物理上不可能，暗示传感器漂移或固件错误。",
    "kitchen_temp_sensor 在灶具操作期间（06:01, 06:33）多次返回 None，显示传感器功能间歇性丧失。",
    "所有房间的温度传感器在同一时间段内表现出非正常的数值特征（要么巨大偏移，要么丢失），排除了局部干扰的可能性。"
  ],
  "recommended_actions": [
    "立即检查并重置客厅及厨房的温度传感器，确认其固件版本是否更新或有已知 Bug。",
    "联系设备制造商或技术支持，报告传感器读数异常问题，可能需要硬件更换。",
    "在修复前，建议人工定期手动测量室内温度，以确保环境安全，防止因自动温控失效导致的极端温度情况。",

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
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：

## 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: ...",

    "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": "日志显示为独居老人正常的晨间起床、洗漱及短暂外出活动，未发现安全威胁或异常模式。",
  "reasoning": [
    "1. **时间线与行为逻辑分析**：日志时间跨度为 04:40 至 07:05。05:33 卧室灯亮且窗帘开启，符合老年人早起习惯；随后 05:38 卫生间灯亮，06:07 厨房灯亮并启动灶具，表明住户进行了洗漱和早餐准备，行为连贯且符合生活规律。",
    "2. **烹饪安全性评估**：厨房灶具在 06:07 开启，06:25 关闭，持续约 18 分钟。在此期间，厨房运动传感器（Occupancy）在 06:07、06:27 等时间点多次触发为 1，证明有人在厨房内活动，排除了“无人看管烹饪”的风险。",
    "3. **门锁与出入状态分析**：07:04 入户门出现锁状态变化（LockState 2->1，即从锁定变为解锁再锁定，或反之，结合 Event 描述为 Manual 操作）。考虑到 07:04 之前所有房间（包括客厅、卧室、厨房）的运动传感器均显示 Occupancy=0 或无活动迹象，且 07:04 后玄关运动传感器触发，这极可能是住户出门倒垃圾、取快递或短暂外出。由于是独居老人，这种短暂的短时外出属于正常行为，且门锁最终恢复锁定状态，无入侵迹象。",
    "4. **设备状态检查**：温度传感器读数在 23-25°C 之间波动，属于正常室温范围，无火灾高温报警。烟雾报警器无触发记录。漏水传感器无触发记录。"
  ],
  "key_evidence": [
    "05:33 bedroom_light OnOff=True 伴随 bedroom_occupancy=1，确认住户起床。",
    "06:07 kitchen_cook_surface OnOff=True 与后续 kitchen_occupancy=1 同时存在，确认为有人看管的正常烹饪。",
    "07:04 front_door_lock LockState 变化及 entrance_occupancy=1，结合此前全屋静默，判断为正常短时外出。",
    "全程无 smoke_co_alarm 或 water_leak_detector 报警。"

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
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",

}
```

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。

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
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:
{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "child_safety",
  "threat_description": "放学后长期只有浴室活动",
  "reasoning": [
    "推理步骤1: 放学后长时间只有浴室相关信号",
    "推理步骤2: 缺少回到儿童房或公共区域的链路",
    "推理步骤3: 存在异常风险"
  ],
  "key_evidence": [

Rejected response:
```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示家庭处于正常的无人/休息状态，所有房间无人员活动，温度变化符合自然散热规律，次卫灯光开启为预设定时任务，未发现安全威胁。",
  "reasoning": [
    "时间分析：日志时间为下午 14:30 至 17:30，结合 occupancy_sensor 全为 0 且跨天摘要显示各房间计数均匀（均为 48），推断此时段为家庭成员外出或集体休息的常规时段。",
    "环境一致性：全屋温度传感器读数在 23.5°C - 24.5°C (即 2350-2450 mK) 之间缓慢下降，这是空调关闭后室内热量自然散失的正常物理现象，无异常升温或骤降。",
    "设备行为逻辑：second_bathroom_light 在 16:30、16:45、17:00 分三次开启，间隔均为 15 分钟，呈现严格的周期性模式，极大概率是智能家居系统的‘定时任务’或‘离家模式’下的自动执行，而非人为闯入迹象。",
    "无冲突事件：虽然重点标记了 kids_room，但该房间 occupancy 持续为 0，且无任何门窗接触传感器报警或烟雾/漏水等危险信号，儿童房处于安全的空置状态。"
  ],
  "key_evidence": [
    "所有房间 occupancy_sensor 在整段日志中持续报告 Occupancy = 0。",
    "second_bathroom_light 的 OnOff 状态变化呈现完美的 15 分钟周期规律（16:30, 16:45, 17:00）。",
    "温度数据随时间推移呈现平滑、线性的下降趋势，符合热力学自然冷却特征。"
  ],
  "recommended_actions": [
    "确认 second_bathroom_light 的 15 分钟循环开关是否为预期的自动化场景设置，若无需此功能可在 Matter 配置中禁用该定时任务以减少干扰。",
    "继续保持当前监控策略，系统运行正常，无需额外干预。"
