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

  "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。

    "推理步骤 4: 与此同时，客厅和卧室的温度传感器读数稳定且合理（约 22-23°C），表明其他传感器工作正常。这种单一传感器的极端异常排除了环境整体过热的可能性，确认为传感器故障或校准失效。",
    "推理步骤 5: 由于该传感器负责监测厨房这一高风险区域，其失灵可能导致烟雾报警器未能及时联动或用户无法通过远程监控得知真实火情，构成潜在的安全隐患。"

## 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",

    "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。

    "跨天活动模式稳定性：对比三天摘要，虽然 07-06 和 07-07 的 entrance 事件数显著高于 07-05（可能包含周末访客或外出归来多次），但各房间内部的 occupancy 变化与温度波动均呈现自然的昼夜节律（早晨升温、夜间无人），未出现设备长时间离线、误报或逻辑冲突（如门开着但人不在却持续报警）。",
    "关键设备状态正常：厨房灶具、烟雾报警器、漏水检测器等安全相关设备在日志中无异常触发记录；洗衣机、洗碗机等家电仅在预期时间段有少量交互或无交互，符合待机或正常使用状态。"

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。

    "设备状态一致性：所有温度读数（约 23°C）处于正常舒适范围，无过热或骤降；烟雾报警器未触发；漏水传感器无报警。虽然 18:25 厨房温度传感器短暂报空值 (None) 后恢复，但这属于常见的通信丢包或重启现象，且不影响后续读数，不构成故障。",
    "结论：整个序列展示了完整的‘归家 - 生活 - 烹饪’闭环，没有检测到尾随进入、非法闯入、火灾风险或设备卡死等异常模式。"

    "建议定期维护厨房温度传感器，防止因信号干扰导致的数据丢失（如 18:25 的 None 值）。"

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: ...",

    "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。

    "门锁操作合规：入户门仅在早上 07:21 出现一次完整的‘解锁 - 开门 - 关门’序列，随后门接触传感器状态变为 False（门外），符合正常的出门行为，无非法入侵或锁具故障迹象。",
    " occupancy 状态连贯：运动传感器的状态变化（0 到 1）均发生在合理的活动时间段内，且没有检测到长时间无人但温度持续升高的异常情况（排除火灾风险）。"
  ],
  "key_evidence": [
    "2026-08-27T07:21:00 至 07:21:28 期间记录了标准的出门开锁和关门流程。",

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

  "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",

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
{

  "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",

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 2376-2350），远超正常物理温度范围，且随后出现数据波动和下降趋势，表明传感器可能故障或受到干扰。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，从 2026-07-12T16:40:00 开始，living_room_temp_sensor 报告的 MeasuredValue 在 2376 到 2350 之间。智能家居设备通常使用摄氏度 (°C) 或华氏度 (°F)，但即使是华氏度，2376°F 也意味着超过 1300°C 的极端高温，这在普通住宅环境中是不可能的；如果是摄氏度，则更是严重错误。",
    "推理步骤 2: 观察后续数据变化，数值并未稳定在一个合理的室温（如 20-25°C/68-77°F），而是呈现出不规则的下降趋势（2376 -> 2350 -> 2342...），并在 18:45 左右降至 2292。这种‘高位虚高后缓慢回落’的模式不符合真实环境温度随空调或自然散热变化的线性规律，更像是传感器读数溢出、校准错误或通信噪声导致的异常值。",
    "推理步骤 3: 结合上下文，同一时间段内其他房间（主卧、儿童房、厨房）的温度传感器读数均在 2300-2340 左右的区间波动（同样存在单位或基准偏移嫌疑，或者整体系统存在某种偏移），但客厅作为重点监控区域，其初始读数显著高于其他区域且逻辑上不合理。考虑到入户门在 18:20 打开，若为入侵者携带热源，温度应迅速上升并伴随运动传感器触发，但运动传感器全程显示无人（Occupancy=0），排除了人为热源导致的高温可能性。因此，最可能的原因是传感器硬件故障、固件 bug 或 Matter 协议传输中的数据类型解析错误。"
