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: ...",

    "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"

  ],

  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示住户活动规律，设备状态与时间戳逻辑一致，未发现安全威胁或异常模式。",
  "reasoning": [
    "温度数据合理性分析：所有温度传感器（living_room, kitchen, bedroom）的 MeasuredValue 均在 2405-2557 范围内。考虑到 Matter 协议中温度通常以 0.1°C 为单位存储整数，该范围对应 24.05°C 至 25.57°C，符合夏季室内正常居住温度，无过热或传感器漂移迹象。",
    " occupancy 行为逻辑验证：卧室 (bedroom) 和客厅 (living_room) 的占用状态变化符合典型作息。例如，早晨 8:00 左右卧室有人进入随后离开，下午 13:38 再次出现，晚上 20:03 后持续有人，且伴随窗帘开合（08:43 卧室窗帘关闭）和灯光开启（08:26 卧室灯开启），这些联动行为表明是住户的正常生活轨迹，而非入侵者试探。",
    "跨天模式一致性：对比三天（8/15, 8/16, 8/17）的摘要数据，每日的 living_room 和 bedroom 事件数量波动在合理范围内（如 8/17 白天活动减少可能因外出或休息），且没有出现设备突然离线、状态卡死或与其他房间传感器产生矛盾（如卧室有人但窗户传感器异常触发）的情况。",
    "关键设备状态确认：入户门锁、烟雾报警器等关键安全设备在日志片段中未报告故障或异常触发，厨房灶具和洗碗机也未出现长时间无人看管的高温运行记录。"
  ],
  "key_evidence": [
    "温度值稳定在 24-26°C 区间，无极端高温或低温突变。",
    "卧室占用状态与窗帘位置、灯光状态存在合理的时序关联（人进屋->开灯/关窗->人走）。",
    "三天内的活动频率分布符合正常家庭作息习惯，无长时间异常静默或高频随机触发。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",
    "建议定期校准温度传感器以确保长期精度。"
  ]

## 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",

  ],
  "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。

    "人员活动模式合理：主卧、儿童房及公共区域的人员占用状态与时间戳吻合，夜间（00:00-07:32）主卧无人而其他房间偶有活动符合睡眠习惯，白天及傍晚家庭成员在各房间间正常流动，无异常徘徊或长时间滞留现象。"

  "key_evidence": [

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。

    "设备行为：客厅主灯在 19:00、19:05、19:10 等时间点频繁开关，但每次间隔极短（5-10 分钟），结合当时无人状态，可能是用户远程测试、误触或智能场景的自动调试，但未伴随人员进入或其他危险信号（如烟雾报警、漏水报警），属于可接受的偶发行为。",
    "综合判断：无任何入侵尝试（门锁未动、窗户未开）、无火灾风险（烟雾传感器未触发）、无设备卡死或数据漂移现象。整体环境安全。"
  ],
  "key_evidence": [
    "18:30 - 20:00 期间，全屋运动传感器连续报告 Occupancy = 0。",

  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议关注客厅灯光在无人状态下频繁开关的原因，确认是否为智能家居自动化规则冲突或用户误操作，必要时调整场景设置。"

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。

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：

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",

  ],
  "key_evidence": [

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",
  "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。

  "reasoning": [
    "推理步骤 1: 分析日志发现从 16:40 开始，living_room_temp_sensor 报告的 MeasuredValue 在 2300 到 2384 之间波动。考虑到 Matter 协议中温度通常以 0.1°C 为单位存储，这些数值实际代表 23.0°C - 23.8°C，这在逻辑上是合理的；然而，若系统未进行单位转换直接显示原始值，或者该设备固件将整数部分误报为摄氏度（即实际温度高达 2300°C），则构成严重异常。",
    "推理步骤 2: 进一步观察发现，在 19:00 左右，kitchen_temp_sensor 的读数突然跳变至 2424 和 2488。结合同一时间段 kitchen_cook_surface 被开启的事件，如果这是真实温度，意味着厨房瞬间达到 2400°C+，这会导致火灾并烧毁房屋，显然不符合常理。更可能的情况是传感器硬件故障、通信干扰导致的数据包解析错误，或者是固件 Bug 导致的数值溢出/错位。",
    "推理步骤 3: 对比卧室温度传感器（bedroom_temp_sensor）在同一时间段的读数（约 2100-2200），虽然也偏高，但趋势相对平稳且与客厅/厨房的剧烈跳变模式不同。这种多房间传感器同时出现非物理级高读数的现象，极大概率不是环境变化引起的，而是传感器本身的 malfunction（故障）或网络传输中的数据包损坏。特别是厨房传感器在烹饪开启后数值飙升，属于典型的传感器失效特征。",
