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。

## 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。

  "reasoning": [
    "1. 分析温度数值合理性：日志中 `kitchen_temp_sensor` 的读数在 2265 到 2557 之间波动。根据 Matter 协议标准，TemperatureMeasurement.MeasuredValue 的单位是厘氏度（centi-degrees Celsius），即需要除以 100 得到摄氏度。因此，这些读数对应的是 22.65°C 至 25.57°C。这个温度范围对于室内环境来说是完全正常且合理的，并非传感器本身损坏导致的极端值（如几千度的高温）。",
    "2. 识别关键异常点：在 06:10:02，`kitchen_temp_sensor` 的读数变为 `None`。随后在 06:35:00 恢复为 2493 (24.93°C)。这种中间值的突然丢失通常表明传感器通信中断、电池电量不足或模块临时故障。",
    "3. 结合住户行为分析：该家庭为独居老人。虽然温度读数本身正常，但传感器在早晨（老人可能起床活动的时间段）出现数据断连，可能导致基于温度的自动化场景（如空调控制）失效或误判。此外，06:09 厨房有人（Occupancy=1），紧接着传感器数据异常，需排除是否因烹饪热源导致局部过热触发保护机制而暂时停止上报，但更可能是设备本身的稳定性问题。",
    "4. 综合判断：主要威胁并非来自入侵或火灾，而是设备可靠性问题。`sensor_malfunction` 是最贴切的分类，因为数据的不连续性和潜在的单点故障风险影响了智能家居系统的完整性。"

    "推理步骤 3: 结合住户为独居老人的背景，厨房出现长时间无人看管的高温状态（尽管有 occupancy 信号，但可能是误报或人员在远处），且温度数值远超正常室温范围，极有可能是灶具干烧、电路过热或燃气泄漏导致的燃烧初期迹象，触发了烟雾报警器前的温度预警阶段。",

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

  "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. 分析温度数值单位：日志中的 `MeasuredValue` 为整数，如 2534、2273。在 Matter 协议中，TemperatureMeasurement Cluster 的 measuredValue 通常以厘氏度（centi-degrees Celsius）为单位，即除以 100 得到摄氏度。因此，2534 代表 25.34°C，2273 代表 22.73°C。这些数值本身处于室内正常温度范围（约 20-26°C）。",
    "2. 识别异常点 A (初始值)：[2026-08-05T00:00:00] 记录值为 2273 (22.73°C)。虽然这在物理上是可能的，但结合后续 08:00 后的稳定高温环境，且该时间点通常为夜间，若未开空调，此值略高但尚可接受。然而，更关键的异常在于后续出现的非物理值。",
    "3. 识别异常点 B (负值)：[2026-08-05T14:05:00] 记录值为 -500。转换为摄氏度为 -5.00°C。在夏季（8月）的室内客厅环境中，除非传感器被故意放入冰箱或室外极寒环境，否则室内不可能达到 -5°C。这明显是一个传感器故障、校准错误或数据传输损坏的信号。",
    "4. 识别异常点 C (剧烈波动与恢复)：在 -500 之后，[14:10:00] 立即跳回 2460 (24.60°C)，随后在 14:10 同一分钟内又变为 2440。这种从 -5°C 瞬间跳变到 24°C 的行为不符合热力学惯性，进一步证实了传感器读数不可靠。",
    "5. 对比其他传感器：同一时间段内，厨房、主卧、次卧的温度传感器读数均在 23.8°C - 24.8°C 之间平稳变化，符合夏季室内环境温度特征。唯独客厅传感器出现极端离群值，排除了全屋性环境突变的可能。"

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。

    "2. 识别关键异常点：在[2026-08-08T14:05:00]，卧室温度传感器报告值为 -500（即-5.0°C），这在室内环境中极不可能，且与前后时刻的2430和2440形成巨大反差，属于典型的传感器故障或通信错误导致的无效数据。",

    "4. 对比其他设备：客厅和厨房的温度传感器读数相对稳定或在合理范围内波动，未出现类似的极端负值或单一方向的剧烈漂移，排除了全屋环境突变的可能性，进一步指向卧室传感器本身的问题。"

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。

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。

    "推理步骤 1: 检查洗衣机状态日志，发现设备在 10:00 启动 (OperationalState=1)，并在 10:20、10:40、11:00 多次报告倒计时时间 (CountdownTime=2400 秒/40 分钟)。这表明设备正在按计划执行洗涤程序，且计时器逻辑工作正常，未出现卡死或状态丢失。",
    "推理步骤 2: 结合上下文环境分析，虽然日志中未直接显示阳台门传感器 (contact_sensor) 的状态变化，但入户门 (entrance) 和玄关 (entrance_occupancy) 的频繁进出记录（07:12, 07:42, 08:37 等）表明住户在家中有正常的活动轨迹。住户进入家中后使用阳台洗衣机的行为符合日常生活习惯。",
    "推理步骤 3: 排除其他潜在风险。厨房温度传感器读数稳定在 25°C 左右，无过热迹象；烟雾报警器未报警；漏水传感器无触发记录。整体家庭环境处于受控的安全状态，洗衣机的持续运行是预期的正常操作。"
