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
请综合以下多个设备与环境状态，评估家庭整体安全状况，指出任何潜在风险。

请按以下 JSON 格式回答：

  "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",

    "2. 分析状态含义：Matter协议中，ContaminationState通常用于指示传感器是否被灰尘、昆虫等污染导致误报风险增加，或者传感器本身出现故障。状态值从1变为2再变为3，呈现恶化趋势。状态3通常对应 'Critical' 或 'Maintenance Required'，意味着设备无法可靠工作。",
    "3. 排除其他干扰因素：虽然7月23日07:11有灶具关闭记录，但并未伴随烟雾报警触发（如FireState=1），说明当时没有真实的火灾或浓烟产生。因此，报警器的状态变化并非由真实火情引起，而是设备自身的问题。",
    "4. 评估安全风险：烟雾报警器是家庭防火的核心安全设备。如果其处于故障或高污染状态，一旦发生火灾将无法及时报警，构成严重的安全隐患（Safety Device Failure）。"

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。

    "2. 分析状态含义：根据 Matter 协议及常见智能家居标准，ContaminationState 通常用于指示传感器是否被灰尘、昆虫或其他污染物堵塞。数值递增（1->2->3）通常表示污染程度加剧或从‘警告’升级为‘严重/故障’。第3天的状态 '3' 极大概率对应 'End of Life' (EOL) 或 'Sensor Fault'，意味着设备已无法正常工作。",
    "3. 排除误报与关联分析：虽然同一时间段内温度传感器读数正常且无剧烈波动，排除了真实火灾引发的报警；同时没有检测到 CO 浓度异常。该问题纯粹指向安全设备自身的健康状态。由于这是连续三天的趋势，说明用户可能忽略了之前的警告，或者设备处于高粉尘环境（如厨房烹饪油烟）导致快速老化。",
    "4. 风险评估：烟雾报警器是家庭防火的第一道防线。如果设备处于污染或故障状态，一旦发生火灾将无法及时报警，构成严重的安全隐患（Safety Device Failure）。"

  "reasoning": [
    "推理步骤 1: 分析厨房温度传感器数据，发现从 7 月 6 日 06:50 到 9 月 8 日（日志时间跨度较大，推测为连续监测），厨房温度读数（单位应为 0.1°C）长期维持在 250-255 之间，换算后约为 25.0°C - 25.5°C。虽然单看数值看似正常室温，但结合后续事件看，该区域可能存在热源积聚或设备故障导致的热环境不稳定。更关键的证据在于报警器的状态变化。",
    "推理步骤 2: 检查烟雾报警器（kitchen_smoke_alarm）的状态。在 7 月 6 日 08:00、7 月 7 日 08:00 以及 7 月 8 日 08:00 三个时间点，ContaminationState 分别报告为 1、2、3。根据 Matter 协议及常见传感器定义，这通常代表检测到的污染物浓度等级逐渐升高（例如：1=轻微/警告，2=中等/注意，3=严重/危险）。这种逐日递增的污染状态表明厨房内存在持续性的燃烧产物或高温气体泄漏，而非偶发事件。",
    "推理步骤 3: 结合住户行为日志，在 7 月 6 日和 7 月 7 日的早晨时段（约 07:30-08:00），客厅和卧室均无人员活动（Occupancy = 0），且入户门锁有开启记录，说明住户可能已离家或处于非活跃状态。然而，厨房作为重点监控区域，其温度并未回落至正常待机水平，且烟雾报警级别持续上升，这表明即使无人操作，厨房内部仍存在潜在的火灾隐患（如灶具未关火、电器过热自燃或燃气泄漏遇热）。",
    "推理步骤 4: 综合判断，烟雾报警器连续三天在同一时间点（08:00）升级报警级别，且伴随温度读数的高位徘徊，构成了明确的火灾前兆或正在发生的低强度火灾风险。这不是正常的烹饪残留气味，而是需要立即干预的安全威胁。"

    "在报警触发期间及之后，living_room_occupancy 和 bedroom_occupancy 多次显示为 0，表明现场可能无人值守，增加了火势蔓延的风险。",
    "kitchen_temp_sensor 读数在报警期间长期维持在较高区间（~2500-2550 mK），未出现明显的降温趋势，暗示热源持续存在。"

## 任务
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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: ..."
  ],

    "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": "厨房烟雾报警器出现持续性故障状态（污染/维护指示），且伴随温度传感器数据异常，需立即检查设备硬件或进行复位。",
  "reasoning": [
    "1. **识别关键异常事件**：日志中明确记录了厨房烟雾报警器（kitchen_smoke_alarm）在三天内连续触发 `SmokeCoAlarm.ContaminationState` 变化：7月14日为1，7月15日为2，7月16日为3。根据Matter标准，该属性通常表示设备的污染程度、维护需求或故障等级，数值递增表明问题未解决且在恶化。",
    "2. **排除真实火灾风险**：尽管存在报警器的故障状态，但同一时间段内（06:00-09:00），厨房灶具（cook_surface）仅在7月14日短暂开启并关闭，后续两天未检测到灶具开启事件。同时，厨房温度传感器读数虽随时间缓慢上升（从2477升至2550+，单位可能是0.01摄氏度即24.77°C至25.50°C），但并未出现火灾导致的急剧温升。因此，判定为设备自身故障而非真实火情。",
    "3. **结合用户画像分析**：住户为独居老人。烟雾报警器是关键的消防安全设备，其处于“污染/故障”状态意味着在真正发生火灾时可能无法正常工作或产生误报干扰。对于独居老人而言，依赖此类安全设备的可靠性至关重要。此外，7月15日和16日早晨厨房温度传感器报告 `None`，进一步暗示该区域传感器网络可能存在连接不稳定或硬件老化问题。"

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。

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。
