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
请结合下面的 Matter 设备日志，判断是否存在设备健康问题，并说明可能的故障类型。

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。

  "reasoning": [
    "1. 传感器数据异常：日志显示 kitchen_temp_sensor 在 11:08:00 的测量值为 'None'，表明传感器通信中断或硬件故障。同时，该传感器在 09:25 至 10:40 期间持续报告约 2550-2554 (即 25.5°C) 的高温，而同一时间段 living_room_temp_sensor 报告约 2530-2560 (25.3-25.6°C)，虽然数值接近，但结合后续灶具关闭后的读数波动，需警惕传感器漂移或受局部热源干扰。",
    "2. 灶具使用模式分析：kitchen_cook_surface 在 06:21 和 11:27 两次被设置为 False (关闭)。然而，kitchen_occupancy 在 11:27 之后直到日志结束 (12:02) 一直为 1 (有人)。对于独居老人家庭，长时间停留在厨房且灶具刚关闭，若未伴随其他活动（如洗碗、清洁），可能存在忘记关火后离开，或者因身体不适导致行动迟缓的风险。",
    "3. 综合判断：虽然目前没有直接的火灾报警（smoke_co_alarm 无触发），但关键的安全监控设备（温度传感器）失效，加上灶具使用后的人员滞留行为，构成了安全隐患。主要问题指向传感器本身的可靠性下降（malfunction），这会导致后续无法准确监测厨房环境变化。"

## 任务
请结合下面的 Matter 设备日志，判断是否存在设备健康问题，并说明可能的故障类型。

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。

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
请结合下面的 Matter 设备日志，判断是否存在设备健康问题，并说明可能的故障类型。

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。

  "reasoning": [
    "1. 分析温度数据的合理性：在2026-08-05这一天，其他房间（厨房、主卧、次卧）的温度传感器读数均在23°C至25°C之间波动，符合夏季室内空调环境的正常范围。然而，客厅温度传感器在13:15至13:55期间多次上报29.2°C、29.4°C甚至29.6°C的数值，这与周围环境的温差过大（超过4-5度），且缺乏合理的物理原因解释（如阳光直射通常不会导致如此剧烈的瞬时跳变后迅速回落）。",
    "2. 识别异常模式：观察日志发现，客厅温度传感器在13:15报出2920 (29.2°C)，随后在13:35报出2940 (29.4°C)，13:55报出2960 (29.6°C)。这些数值呈现非线性的异常升高，且在14:00突然回落到正常的24.8°C左右。这种‘尖峰’式的异常读数不符合热惯性规律，极有可能是传感器内部元件故障、ADC转换错误或固件Bug导致的‘鬼影’数据。",
    "3. 结合设备状态验证：虽然客厅空调在13:00开启（OnOff=True），但这通常是为了降温，而非导致室温异常飙升。如果空调故障导致过热，温度应持续上升而非瞬间回落。此外，客厅 occupancy 传感器在此期间一直显示为0（无人），排除了人体热源对局部微环境造成剧烈干扰的可能性。因此，判定为传感器本身的 malfunction。"

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",

  ],
  "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。

    "2. 分析关联环境数据：在 bedroom_occupancy 保持活跃的同时，厨房 (kitchen) 的 occupancy 传感器也频繁报告为 1 (例如 07:20, 08:15, 09:20, 09:55)，表明老人在家中走动，符合日常起居逻辑。",
    "3. 发现关键异常点：在 05:56:07，厨房温度传感器 (kitchen_temp_sensor) 返回了 'TemperatureMeasurement.MeasuredValue = None'。随后在 07:10 恢复数值，但整体温度读数呈现非自然的线性增长趋势（从凌晨2200左右升至早晨2500+，即22°C至25°C以上），且中间出现数据缺失。",
    "4. 综合判断：虽然重点关注的 bedroom_occupancy 本身无异常，但日志中暴露出的 kitchen_temp_sensor 数据丢失 (None) 是明显的硬件或通信故障迹象。考虑到这是智能家居安全分析，传感器失效可能导致火灾或高温预警缺失，因此判定存在设备层面的异常。"

    "推理步骤 3: 考虑到住户为独居老人，若发生燃气泄漏或油锅起火等事故，初期可能无烟雾报警触发（或传感器故障），而温度的持续异常升高是火灾前兆的最强信号。当前温度趋势表明室内环境已处于危险的高温状态，极大概率发生了未受控的燃烧或加热事件。"

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
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。

  "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",

    "1. 分析关键事件序列：在 09:10:00 至 09:12:00 之间，客厅窗帘执行了两次开合操作（CurrentPositionLiftPercent100ths = 0），同时窗户接触传感器在 09:10:00 显示为 True (Closed)，但在 09:12:00 变为 False (Open)。",
    "2. 结合物理逻辑判断：通常智能窗帘关闭时（位置0%），如果窗帘盒设计合理，不应触发窗户接触传感器报警（即不应显示为打开）。然而日志显示窗帘关闭的同时/之后，接触传感器报告了“打开”状态。",
    "3. 排除人为入侵可能：此时段（上午9点）卧室和厨房均有人员活动迹象（Occupancy=1），且入户门未开启，无其他异常入侵特征。这种短暂的、与设备动作同步的状态翻转，更符合传感器安装松动、磁铁错位或窗帘轨道干涉导致的信号抖动。",
    "4. 综合评估：虽然温度数据正常，但针对重点关注的窗户安全设备，其状态变化不符合正常的‘人-窗’交互逻辑（即人不在场时窗户保持关闭，或人离开后窗户被手动打开），而是与自动化设备动作冲突，判定为传感器硬件或安装层面的故障。"

    "推理步骤 2: 关键异常发生在 09:10:00。此时日志记录显示客厅窗户位置 (living_room_window) 为 0%（关闭），但仅 2 分钟后 (09:12:00)，窗户接触传感器 (living_room_window_contact) 的状态突然从 True 变为 False。结合上下文，这极可能意味着窗户被从外部强行推开，导致传感器逻辑翻转或物理触发，而系统未能及时响应这一变化。",
    "推理步骤 3: 综合行为模式，住户在早晨 (06:32-08:55) 有正常的卫生间和卧室活动记录，但在 09:00 左右卧室 occupancy 再次变为 1 后，紧接着发生了窗户异常开启事件。考虑到前门在 07:19 已被打开过，若住户当时并未完全离开或处于非正常状态，那么 09:10 的窗户异常配合之前的开门记录，强烈暗示了有人利用前门进入后，试图通过窗户通风或逃离，或者是入侵者正在屋内活动。特别是窗户传感器在‘关闭’状态下瞬间变为‘打开’，符合暴力破窗或推窗的特征。",

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: ..."
  ],
  "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:

  "reasoning": [
