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",

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": "客厅温度传感器读数异常偏高且持续上升，远超正常室温范围，疑似传感器故障或安装位置错误。",
  "reasoning": [
    "1. 分析温度数据趋势：从03:10到11:05，客厅温度传感器（living_room_temp_sensor）的读数从2364持续攀升至2544。在Matter协议中，TemperatureMeasurement.MeasuredValue通常以厘氏度（centi-degrees Celsius）为单位，即除以100得到摄氏度。因此，读数2364对应23.64°C，而2544对应25.44°C。虽然25.44°C处于人类可接受的室内温度范围内，但关键在于其变化趋势和绝对值与其他房间的对比。",
    "2. 对比其他房间数据：在同一时间段内，卧室温度传感器读数稳定在23.90°C - 24.53°C之间，厨房温度传感器读数在24.86°C - 25.59°C之间波动。客厅作为主要活动区域，其温度理应接近人体舒适区（约22-24°C）。然而，日志显示客厅温度从凌晨开始就高于卧室，并随时间推移不断升高，甚至在上午9点后超过了厨房温度（例如09:20时客厅25.51°C vs 厨房25.51°C，随后客厅略低但仍偏高）。",
    "3. 结合环境逻辑判断：在没有开启空调制冷或制热设备（日志中未显示空调动作，且 occupancy 为 0 表示无人）的情况下，室内温度不应出现如此单调、持续的线性上升趋势，尤其是在夜间至清晨时段。这种‘漂移’现象更符合传感器自身故障（如校准错误、内部元件老化）或传感器被放置在热源附近（如阳光直射、电器散热口）的特征。考虑到这是智能家居安全分析，传感器提供错误的环境数据可能导致自动化策略（如空调联动）失效，属于设备层面的异常。"

## 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",
  "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。

  "reasoning": [
    "1. 分析数据范围：Matter协议中TemperatureMeasurement.MeasuredValue通常以0.01°C为单位上报。日志中大部分数值在2358-2558之间，对应室温约23.6°C-25.6°C，符合正常家庭环境特征。",
    "2. 识别异常点：在[2026-08-08T14:05:00]时刻，living_room_temp_sensor上报值为-500，这在物理上是不可能的（除非极寒环境且传感器未校准，但结合前后文2430和2440来看，这显然是错误数据）。",
    "3. 观察趋势异常：在异常点前后，温度读数呈现非自然的剧烈波动。例如从14:00的2430骤降至14:05的-500，随后在14:10回升至2440，14:15又升至2475。这种短时间内的大幅震荡不符合热惯性规律，表明传感器可能存在间歇性故障、电池电量不足导致信号不稳定，或者内部ADC转换错误。",
    "4. 排除其他因素：同一时间段内，厨房和其他房间的温度传感器读数变化平缓且合理（如kitchen从2497降至2457），说明并非全屋环境突变，而是特定设备问题。"

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",

    "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。

    "在17:00:00时刻，该传感器突然上报温度为2920（即29.2°C），这是一个显著高于当前环境温度且与前后数据不连续的突变。",
    "紧接着在17:10:00，温度立即回落到22.54°C，并在此后保持正常的缓慢下降趋势（22.52°C -> 22.29°C等）。",
    "这种“尖峰”式的瞬时异常读数不符合物理热惯性规律（房间温度不会在10分钟内先急剧升高再急剧降低），也不伴随其他设备（如空调、窗户状态）的联动变化，因此判定为传感器硬件故障、校准漂移或通信数据包错误。"

  "recommended_actions": [
    "检查卧室温度传感器的电池电量，低电量可能导致读数不稳定。",
    "尝试重启该温度传感器或重新配网，以排除临时性软件/通信故障。",

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",

    "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。

{

  "threat_type": "intrusion",
  "threat_description": "检测到疑似入侵行为：住户在离开卧室后，于无人状态下打开客厅窗户并关闭窗帘，随后门锁被手动操作且门传感器状态异常。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，在 07:40 左右，入户门锁 (front_door_lock) 发生了手动上锁操作 (LockOperationType=1)，紧接着 (31 秒后) 入户门接触传感器 (front_door_contact) 报告状态为 True (通常表示门已打开或处于非闭合安全状态，取决于具体定义，但结合上下文更可能是门被打开或传感器误报导致状态翻转)。",
    "推理步骤 2: 关键异常发生在 09:10-09:12。此时 living_room_occupancy 持续为 0 (无人)，living_room_window_contact 先变为 True (窗户打开)，随后仅过 9 秒 (09:12:09) 又变为 False (窗户关闭)。这种极短时间内‘开窗 - 关窗’的动作模式，在无人居住的情况下极不自然，不符合正常通风习惯，更像是有人进入室内操作后迅速撤离或试图掩盖痕迹。",
    "推理步骤 3: 结合 07:40 的出门记录和 09:10 的窗户异常动作，存在一种可能性：有人在住户出门后（或趁其不在时）进入了房屋，打开了窗户（可能为了制造噪音、通风或作为进出通道），并在短时间内关闭了窗户和窗帘 (09:15 窗帘位置仍为 0，即完全拉下/关闭)，试图恢复现场。虽然日志未直接显示窗户再次打开，但‘无人状态下快速开关窗’是典型的入侵前兆或入侵过程中的行为特征。",
    "推理步骤 4: 此外，厨房温度传感器读数极高 (约 254°C，实际应为 25.4°C 但单位缺失或漂移严重)，若确认为真实高温则伴随火灾风险；但考虑到所有房间温度同步偏高且变化趋势一致，更有可能是传感器校准问题或数据格式误解。然而，相比于温度数据的歧义，窗户和门锁的行为逻辑矛盾构成了明确的物理入侵证据链。"
  ],
  "key_evidence": [
    "09:10:00 至 09:12:00 期间，living_room_window_contact 在无人 (Occupancy=0) 状态下发生 'True -> False' 的快速翻转，暗示有人短暂开启并关闭了窗户。",
    "07:40:22 门锁手动上锁后，07:40:31 门传感器立即报告 StateValue=True，可能存在门未关严或非法开启后的状态重置。",
    "09:10:00 窗帘状态 CurrentPositionLiftPercent100ths = 0 (完全关闭)，配合窗户的快速开合，符合‘进入 - 操作 - 复原’的入侵模式。"
  ],
  "recommended_actions": [
    "立即通知住户家中可能有人闯入，建议其回家后立即检查门窗锁具及室内情况。",
    "联系物业或安保人员前往现场核实，特别是检查客厅窗户是否有强行开启的痕迹。",

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",
  "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。

  "threat_description": "玄关运动传感器（entrance_occupancy）在长达6小时的时间段内持续报告有人存在，且状态仅在0和1之间切换但缺乏合理的离开/进入逻辑，疑似传感器故障或卡滞。",
  "reasoning": [
    "分析重点设备日志：观察 `entrance_occupancy` (玄关运动传感器) 的状态变化。",
    "发现异常模式：从 07:30 到 13:32，该传感器频繁上报 Occupancy = 1。具体时间点包括 08:19, 08:39, 09:24, 09:44, 10:04, 10:49, 11:09, 11:54, 12:14, 12:34, 13:19。",
    "排除正常行为：虽然早晨有人员活动，但在上午8点到下午1点半期间，没有任何其他证据（如门锁开启、其他房间长时间无人后突然有人、灯光开关等）表明有人在玄关区域进行正常的进出活动。通常运动传感器在无人的情况下应报0，或在人离开后一段时间报0。此处连续多次报1，且间隔规律（约30-40分钟），不符合人类正常的停留或短暂经过特征。",
    "对比其他传感器：同一时间段内，客厅、餐厅等其他区域的 occupancy 传感器也有波动，但玄关作为入户通道，其持续的高频“有人”信号若无法被其他设备佐证（如门磁未触发开锁），极大概率是传感器自身故障（Stuck-on）或误报。",
    "结论：这种持续的、无实际物理交互佐证的“有人”信号属于典型的传感器卡滞（Sensor Stuck）现象。"
