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
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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。

{
  "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: 日志中未出现持续矛盾、直接告警或高风险时序链路。"
  ],
  "key_evidence": [
    "日志中未出现持续矛盾、直接告警或高风险时序链路。"
  ],
  "recommended_actions": [

  "confidence": "medium",
  "threat_type": "intrusion",
  "threat_description": "这些变化表明存在安全异常。",
  "reasoning": [

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
请根据以下设备记录评估当前是否需要安全响应；若需要，请说明原因与处置建议。

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。

  "confidence": "high",

    "1. 人员活动轨迹符合正常作息：22:26至23:34期间，客厅（living_room）运动传感器持续触发（Occupancy=1），表明有人在该区域活动；同时卧室（master_bedroom, second_bedroom）、玄关（entrance）和卫生间（bathroom）的运动传感器均显示无人（Occupancy=0）。这符合典型的“晚间在客厅休闲/看电视，随后准备休息”的行为模式。",
    "2. 门锁状态逻辑自洽：23:00左右入户门传感器显示关闭（StateValue=True通常表示闭合/锁定状态，结合上下文），且门锁执行了手动上锁操作（LockOperationType=0, LockState=1）。此时客厅有人，说明住户并未离家，而是可能刚回家或正在家中移动，手动上锁可能是为了加强夜间安防或防止误开，属于合理行为。",
    "3. 设备控制符合节能习惯：23:00时，客厅主灯关闭（OnOff=False）且空调关闭（OnOff=False）。这与住户在客厅活动但准备结束活动或调暗环境光的行为一致，没有发现长时间无人却开启高能耗设备的异常情况。",
    "4. 无异常报警信号：日志中未出现烟雾、漏水、一氧化碳等危险传感器的报警记录，也未出现门锁故障或传感器卡死（如长时间无变化后突然跳变）的迹象。"
  ],
  "key_evidence": [

    "front_door_lock 在 23:00:21 执行 Manual 上锁操作，且 front_door_contact 显示门已关闭",
    "living_room_light 和 living_room_ac 在 23:00 同时关闭，符合夜间节能或就寝前行为",
    "所有卧室及公共区域传感器状态与人员位置分布一致，无矛盾"
  ],
  "recommended_actions": [
    "无需采取紧急安全措施",

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
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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": [
    "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": "厨房温度传感器在烹饪活动期间出现严重数据漂移和逻辑矛盾，读数远超物理可能范围且与灶具状态不匹配。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，在 19:10:30 用户开启灶具 (kitchen_cook_surface) 后，厨房温度传感器 (kitchen_temp_sensor) 的读数开始异常飙升。",
    "推理步骤 2: 正常烹饪时，炉灶上方温度通常在 200°C-400°C (约 473K-673K)，而 Matter 协议中 TemperatureMeasurement.MeasuredValue 通常以 0.01°C 为单位或类似比例。日志中数值从正常的 ~2300 (约 23°C) 跳变至 2630、2548，甚至达到 2630 (若按 0.01 换算为 26.3°C，变化幅度极小；但若按某些特定厂商的非标准映射或单位错误理解，这些数值相对于环境温度的波动极其剧烈且不符合热力学规律)。更关键的证据是：在 19:37:00 灶具关闭后，温度读数并未回落至环境温度，反而在 19:45:00 再次飙升至 2630，并在随后几小时内维持在 2400-2600 区间，直到 20:40:00 才突然恢复正常。",
    "推理步骤 3: 这种‘开火升温 - 关火继续高温 - 长时间维持异常高位 - 突然归零/恢复’的模式，完全不符合真实的热传导物理特性。真实的烟雾报警器或高温传感器不会在热源移除后持续报告不可能的高温值长达一小时以上。这表明传感器固件存在 Bug、校准丢失或被恶意篡改，导致数据不可信。",
    "推理步骤 4: 虽然该设备未直接触发火灾报警（smoke_co_alarm 无事件），但一个失效的温度传感器可能导致联动系统（如自动开窗、空调策略）做出错误决策，或者掩盖真实的火灾隐患（如果传感器卡在某个中间值而非极端值）。此外，20:07:05 洗碗机启动时温度读数仍在异常高位，进一步证实了传感器状态的持续性故障。"

    "19:10:30 开启灶具后，温度读数从 ~2300 迅速跳变至 2488。",
    "19:37:00 关闭灶具后，温度读数未下降，反而在 19:45:00 再次升至 2630，并在此后数小时内持续处于 2400-2600 的异常区间，违背热力学常识。",
    "20:40:00 温度读数毫无征兆地突然回落到正常水平 (2253)，显示传感器状态不稳定或存在间歇性故障。"
  ],
  "recommended_actions": [
    "立即检查厨房温度传感器的硬件连接及供电情况，排除接触不良导致的信号干扰。",
    "重置厨房温度传感器并重新校准，检查其固件版本是否为最新。",
    "在修复前，暂时手动监控厨房区域，不要完全依赖该传感器进行自动化安全联动（如联动烟雾报警器的阈值判断）。",

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。

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",

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。

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: ...",
    "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。

{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁，日志显示为正常的夜间居家活动及睡眠准备行为。",
  "reasoning": [
    "1. 时间与环境分析：事件发生在2026-07-29晚间22:15至23:45，属于典型的夜间休息时段。室内温度传感器读数在22.4°C至22.7°C之间（Matter协议中通常单位为0.01摄氏度，即22.45°C等），处于舒适且稳定的范围，无火灾或极端天气迹象。",
    "2. 人员活动模式分析：主卧、客厅和玄关的运动传感器频繁触发（Occupancy=1），表明住户在卧室与公共区域间正常走动。次卧和卫生间传感器显示Occupancy=0，符合夜间无人使用的常态。这种多房间的活动轨迹是典型的睡前洗漱、整理或放松行为。",
    "3. 设备操作逻辑分析：22:40左右，住户关闭了客厅主灯和空调，并打开了主卧窗帘（CurrentPositionLiftPercent100ths=10000表示完全打开，可能是为了通风或查看窗外，也可能是误触，但结合后续动作看并非异常入侵）。随后入户门被手动上锁（LockState=1），这是标准的离家或就寝前的安防加固行为。",
    "4. 排除异常特征：没有发现非法入侵迹象（如门锁被暴力破解、非授权开锁记录）；没有发现漏水、烟雾报警等紧急事件；温度变化平缓，无传感器故障漂移迹象；所有操作均有对应的人员运动传感器支持，排除了自动化脚本误操作或设备故障的可能性。"

    "22:18-23:40期间 master_bedroom_occupancy 多次变为 1 (主卧有人活动)"
