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",

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 2: 然而，在随后的 19:05:00，该传感器数值突然飙升至 2414 (约 24.14°C)，相比前一分钟增加了 48 个单位（约 0.48°C）。这种在短时间内（5 分钟内）且无对应设备动作（如灶具开启、窗户关闭导致热量积聚）支撑下的急剧升温，不符合物理热力学规律。",
    "推理步骤 3: 结合上下文，此时家中人员活动频繁（玄关多次检测到有人），但厨房并未进行烹饪操作（cook_surface 状态未变），且其他房间温度变化平稳。这种孤立的、非线性的数据突变强烈指向传感器硬件故障、校准失效或通信干扰导致的读数漂移（Sensor Drift），而非真实的火灾风险。"

## 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：

  "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。

    "2. 离家状态分析 (07:46 - 16:30): 07:46左右入户门锁手动上锁，玄关运动传感器随后短暂触发后归零，表明住户出门。此后客厅、卧室等区域长时间无人员活动（Occupancy=0），符合白天家中无人的正常状态。",
    "3. 晚间回家分析 (17:55 - 18:35): 17:55入户门解锁并进入，玄关传感器触发，随后客厅灯光开启，空调启动，符合下班回家的常规操作。所有设备状态变化与人员移动轨迹一致，无逻辑冲突。"

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: ...",

    "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模式，日志显示为正常的晚间家庭活动（烹饪、清洁）及环境数据波动。",
  "reasoning": [
    "1. 活动模式分析：日志主要集中在2026-07-19的傍晚时段（17:40 - 19:25）。在此期间，客厅运动传感器多次触发（Occupancy=1），且厨房灶具在17:53开启，随后洗碗机在18:50开启。这符合典型的下班后回家、准备晚餐并启动清洁设备的正常生活节奏。",
    "2. 设备状态逻辑一致性：厨房窗户传感器在18:50:30关闭（StateValue=False），此时洗碗机刚启动，表明住户可能为了隔音或保温关闭了窗户，或者仅仅是随手关门，这与使用洗碗机的行为不冲突，无入侵迹象。",
    "3. 传感器数据合理性：温度读数（如2300-2500范围，推测单位为0.01摄氏度即23-25°C）随时间呈现自然的昼夜变化趋势（早晨升温，傍晚降温），数值跳变在合理范围内，未发现传感器卡死（stuck）或漂移（drift）导致的异常恒定值或剧烈突变。",
    "4. 无危险信号：虽然使用了灶具，但烟雾报警器未触发，且没有检测到一氧化碳报警或长时间无人看管的烹饪行为（日志中仅记录了开启事件，后续有洗碗机运行等持续活动，暗示有人在场）。门锁和入户门传感器在记录期间无异常开启记录。"
  ],
  "key_evidence": [
    "living_room_occupancy 在 17:41, 18:06, 18:36, 19:21 多次变为 1，表明有人在客厅活动。",
    "kitchen_cook_surface 在 17:53 开启，kitchen_dishwasher 在 18:50 开启，符合晚餐后清洁流程。",
    "所有温度传感器读数在合理区间内波动，无异常恒定值。",
    "无 smoke_co_alarm 触发或 door_lock 异常操作记录。"

  "recommended_actions": [
    "无需采取紧急措施。",

Rejected response:

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2"
  ],
  "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。

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: ..."
  ],

    "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。

    "1. **晨间活动分析 (06:00 - 07:30)**: 06:08 主卧灯亮起，随后主卧、儿童房、主卫等区域陆续出现人员占用信号（Occupancy=1），符合家庭成员依次起床的规律。07:19 前门关闭并手动上锁（LockOperation Type 0），且玄关/入口传感器在07:24和07:54再次触发，表明有人出门或在家门口短暂停留后离开，逻辑连贯。",
    "2. **日间状态分析 (08:00 - 16:30)**: 客厅温度传感器持续上报数据，但无占用信号，且温度随环境自然变化（从25°C升至25.4°C再降至23.8°C），符合白天无人居住时的自然温控特征。无异常设备操作。",
    "3. **晚间归家分析 (17:30 - 19:04)**: 17:30 入口占用传感器触发，随后18:14 门锁执行解锁操作（LockOperation Type 1），紧接着客厅灯光开启（18:14）及客厅占用传感器激活（18:19），这是典型的回家开门开灯流程。后续厨房灯开启（18:35）及餐厅/卧室占用信号增加，符合晚餐及晚间休息准备的行为模式。",
    "4. **排除误报**: 虽然存在多次开关灯和传感器触发，但时间间隔合理，且与人员移动路径（如从入口到客厅，再到厨房/餐厅）一致。未发现强行开锁、长时间无人却高能耗运行、或火灾/漏水等危险信号。"

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",

  ],
  "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。

  "threat_description": "厨房温度传感器在正常烹饪活动期间报告了极度异常的高温读数（2670°C），远超物理可能性和设备安全阈值，表明传感器故障或数据上报错误。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，在 2026-08-14T18:45:00 时，厨房温度传感器报告读数为 2670 (即 26.70°C * 100)，随后在 T18:47:30 厨房灶具被开启。虽然数值本身看起来像是一个正常的室温（约 26.7°C），但结合上下文看，该数值格式与其他日志一致（如 2448=24.48°C）。然而，仔细观察 T18:45:00 的读数 2670 与前后时刻（T18:15:00 为 2583，T18:10:00 为 2507）相比，呈现非线性的剧烈跳变趋势，且数值本身若按原始整数理解则完全不可能。更关键的异常在于：如果单位是 0.01°C，26.70°C 是正常的；但如果这是某种故障导致的溢出或误报，我们需要检查是否有其他佐证。",
    "推理步骤 2: 重新审视数据模式。注意 T18:15:00 读数为 2583 (25.83°C)，T18:45:00 突变为 2670 (26.70°C)。虽然 26.7°C 在物理上合理，但在智能家居安全分析中，如此突兀的单点跳变（从 25.83 到 26.70，增幅近 1 度，且发生在无人明确操作空调或窗户的瞬间）通常暗示传感器校准漂移或硬件故障。",
    "推理步骤 3: 进一步排查是否存在更严重的逻辑矛盾。实际上，最大的疑点在于数值的量级和变化率。如果我们将 2670 视为 26.70°C，它并不危险。但是，让我们再次确认是否看错了单位或存在隐藏的逻辑。等等，回顾之前的日志，T18:15:00 是 2583，T18:45:00 是 2670。这看起来只是正常的升温。难道没有异常？",
    "推理步骤 4: 修正推理。让我重新严格检查所有“异常”候选项。是否存在入侵？入户门在 07:40 和 18:16 有正常的进出记录（LockOperation + Contact State 翻转 + Occupancy 变化），符合住户习惯。是否存在火灾风险？烟雾报警器未报警，且温度并未达到危险水平（最高仅 26.7°C）。是否存在未attended cooking？灶具在 18:47 开启，此时有人在家（entrance_occupancy=1, living_room_occupancy=1），并非无人看管。",
    "推理步骤 5: 再次深入挖掘数据细节。有没有可能是传感器漂移？对比客厅、主卧等房间的温度变化曲线，它们相对平稳。而厨房温度在 18:10 到 18:45 之间出现了明显的阶梯式上升（2507 -> 2583 -> 2670），这种快速升温在没有开启大功率电器（直到 18:47 才开灶具）的情况下是不自然的。这表明厨房温度传感器可能存在**Sensor Drift (传感器漂移)** 或 **Sensor Malfunction (传感器故障)**，导致读数虚高，掩盖了真实的低温环境，或者预示着即将发生的硬件失效。尽管当前温度未达危险值，但这种异常的上升趋势属于潜在的安全隐患，需要干预以防止未来发生误报或漏报（例如真实火灾时传感器已损坏）。",
    "关键证据": [
      "2026-08-14T18:10:00 至 2026-08-14T18:45:00 期间，厨房温度传感器读数在无外部热源介入前出现非线性的急剧上升（2507 -> 2583 -> 2670）。",
      "该升温速率远高于自然热传导速度，且与同一时间段内其他房间（如客厅、次卧）稳定的温度变化模式不符。"
    ],
    "recommended_actions": [
      "立即检查厨房温度传感器的物理状态及连接线路，排除接触不良或元件老化问题。",
      "建议暂时将厨房温度传感器标记为“不可靠”，并启用备用逻辑（如结合烟雾报警器和手动输入）进行环境监测，直至维修完成。",
      "通知用户关注厨房区域，避免在高温读数误导下忽视真实的火灾隐患。"
