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",

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: 结合 temperature_sensor 数据分析，在老人离开客厅传感器范围后，客厅温度并未因空调关闭而下降，反而呈现持续上升趋势（例如 08-20 从 23.9°C 升至 24.4°C）。对于独居老人而言，这种‘无人但室温持续攀升’的模式极不寻常，暗示老人可能因生病或跌倒被困在房间内，导致空调系统未被关闭或调节，或者房间密闭导致热量积聚。",
    "推理步骤 3: 对比三天日志，该模式具有高度重复性（均在凌晨 03:30 左右发生），排除了偶然因素。考虑到用户画像为‘独居老人’，这种规律性的夜间长时间静止伴随环境参数异常，是典型的潜在健康危机信号（如中风、心脏病发作后无法起身，或跌倒后无法呼救）。"

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",

    "4. 排除误报：虽然部分传感器数据（如温度值）看起来数值较大（可能是原始单位未转换或特定协议格式），但运动传感器和接触传感器的状态变化逻辑清晰。深夜无预警的开门+开灯+人员移动组合，极大概率指向入侵而非正常的夜间起夜（通常不会先开阳台灯再进客厅，且阳台门开启是首要触发点）。"

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。

以下是过去 3 天的设备活动记录。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。

  "threat_description": "客厅温度传感器读数异常偏高且波动剧烈，显示为摄氏度数值的十倍（例如 2317 代表 23.17°C），表明传感器存在严重的校准漂移或固件故障。",
  "reasoning": [
    "推理步骤 1: 分析日志中的温度数据，发现所有房间的温度传感器报告的值均在 2300-2430 之间（如 living_room_temp_sensor 在 02:00 报告 2322）。考虑到 Matter 协议中温度通常以 0.01°C 为单位存储，实际温度约为 23.22°C，这在物理上是合理的室温范围。然而，数值本身是整数形式而非小数形式，或者设备配置错误导致单位解析偏差，这属于数据格式/校准层面的异常。",
    "推理步骤 2: 观察同一时间段内不同传感器的行为模式。虽然多个房间（客厅、次卧、厨房、主卧）都报告了类似的'高位'整数温度，但更关键的是这些数值的稳定性与变化率。例如，living_room_temp_sensor 在 02:00 到 02:25 期间从 2322 快速上升至 2342，随后又下降至 2336，这种高频的微小整数跳动（±10 个单位即 ±0.1°C 的剧烈震荡）不符合真实热力学环境的热惯性特征，更像是传感器噪声过大或采样逻辑错误导致的漂移。",
    "推理步骤 3: 结合上下文判断威胁等级。尽管没有直接检测到入侵（occupancy 传感器在夜间大部分时间为 0，仅在凌晨短暂触发一次可能误报或正常活动），但温度传感器的严重漂移会导致空调系统基于错误数据运行（如过度制冷或制热），造成能源浪费甚至设备损坏。此外，如果该数值被错误地解释为绝对高温（2317°C），将直接触发火灾报警，构成潜在的安全误报风险。因此，判定为 sensor_drift（传感器漂移/故障）。"
  ],
  "key_evidence": [
    "living_room_temp_sensor 在 2026-07-03T02:00:00 至 04:50:00 期间持续报告 2300+ 的整数值，且数值频繁在几十的范围内无规律波动（如 2322 -> 2342 -> 2336），表现出非物理性的抖动特征。",
    "跨房间一致性检查显示，厨房和主卧传感器也出现了类似的数值偏移（如 kitchen_temp_sensor 达到 2402），暗示可能是全局配置错误或批量固件问题，而非单一设备故障。"
  ],
  "recommended_actions": [
    "立即检查并重置所有受影响的温度传感器设备，确认其固件版本是否为最新。",
    "联系设备制造商或技术支持，核实 Matter 协议下的温度测量单元（Unit of Measure）配置是否正确（应为 0.01°C 而非 1°C 或其他错误映射）。",

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",

    "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": "客厅温度传感器读数严重偏离物理现实，显示异常高温（2300-2400+），且与住户活动模式不匹配，疑似传感器故障或数据漂移。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，从 2026-08-11T01:40:00 开始，living_room_temp_sensor 的 MeasuredValue 持续在 2300 至 2400+ 之间波动。考虑到 Matter 协议中温度通常以 0.01°C 为单位，该数值实际代表 23.00°C 至 24.00°C，这在夏季夜间是合理的室温范围。然而，若假设系统未进行单位缩放或存在严重的浮点数溢出/截断错误，这些数值本身作为原始整数（如 2312）对于普通家用传感器来说极高（2312°C），这显然不可能。更可能的情况是：这是一个单位转换错误（例如将毫开尔文 mK 误报为摄氏度，或者内部存储值未正确除以 100），或者是传感器固件 Bug 导致上报了错误的原始值。",
    "推理步骤 2: 对比同一时间段内的其他房间数据。master_bedroom、kitchen、second_bedroom 的温度传感器也报告了类似的数值范围（2300-2400+）。虽然全屋温度同时升高可能意味着极端天气，但结合时间戳（凌晨 1 点至 4 点），此时室外气温通常较低，室内空调应处于制冷或待机状态，不太可能出现全屋同时达到 2300°C（或即使按 0.01 换算后的异常剧烈波动模式）的情况。更重要的是，这种‘整齐’的高数值分布强烈暗示是数据采集或传输层面的系统性错误，而非真实的热事件。",
    "推理步骤 3: 观察住户行为与设备状态的关联。日志显示在 2026-08-11T03:14:00 和 2026-08-12T03:14:00 左右，living_room_occupancy 短暂变为 1（有人），随后又迅速归零。如果温度传感器正常工作，当有人进入时，由于人体散热，温度应有微小上升或保持稳定；但在日志中，温度读数在人员出现前后并没有表现出符合物理规律的动态变化，而是维持着异常的静态高值。此外，厨房灯光在凌晨 07:32 和 06:33 被开启，这与正常的作息不符（除非是定时任务，但通常不会如此频繁且无关联操作），进一步增加了环境数据的不可信度。综合来看，温度传感器的数据可信度极低，属于典型的 sensor_drift 或 sensor_malfunction（此处归类为 drift 涵盖数据偏差类故障）。",
    "推理步骤 4: 排除入侵风险。虽然入户门传感器（entrance_contact_sensor）未在提供的片段中明确显示‘打开’状态，但 occupancy_sensor 在凌晨时段多次检测到有人（Occupancy=1），且随后立即消失。如果这是入侵者，通常会伴随门窗接触传感器报警或长时间停留。目前的证据链主要指向传感器数据本身的异常，而非明确的入侵行为。因此，首要问题是传感器数据失真。"
