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：

```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",

    "1. 分析烟雾报警器日志：在2026-08-10、08-11、08-12的08:00整点，kitchen_smoke_alarm均上报了SmokeCoAlarm.ContaminationState变化，分别为1、2、3。根据Matter标准，ContaminationState通常指示传感器内部积尘或老化导致的灵敏度漂移/故障，数值递增表明问题在持续恶化，而非偶发干扰。",
    "2. 排除真实火灾/燃气泄漏：虽然日志显示灶具(cook_surface)在早晨关闭，但随后的温度传感器(kitchen_temp_sensor)读数并未出现火灾特有的急剧飙升（如从25°C瞬间升至数百度），而是维持在24-25°C左右的正常室温波动范围（例如2500-2550对应25.0-25.5°C）。这表明没有发生燃烧事件。",
    "3. 结合住户行为模式：独居老人在早晨使用灶具是正常行为。如果存在真实的火灾隐患，通常会伴随CO报警或极高的温度读数。目前的“污染状态”更指向硬件维护需求。",
    "4. 综合判断：这不是入侵、跌倒或健康危机，也不是真正的火灾风险，而是安全设备本身的故障信号。如果不处理，可能导致未来真正发生火灾时设备失效，或造成持续的误报焦虑。"

    "2. 分析时间规律与行为关联：该异常发生在早晨08:00，此时住户通常开始起床活动（entrance_occupancy=1表示有人进入玄关），且厨房温度传感器读数从约25°C上升至25.3-25.5°C左右。这种规律性的定时触发排除了偶发性干扰（如偶尔的烹饪油烟），更指向设备本身的周期性自检失败或内部元件故障。",

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。

    "2. 分析人员活动轨迹：虽然 18:50-19:00 期间卧室和客厅有 occupancy 信号（可能为老人走动或传感器误报），但在灶具开启后的关键时段（19:00-19:20），厨房 occupancy_sensor 仅在 19:20 整点报告一次 '1'，而在 19:04 卫生间有人离开，19:24 玄关有人进入。这表明老人在灶具开启期间并未稳定停留在厨房进行烹饪操作，极可能发生了遗忘关火的情况。",
    "3. 分析环境数据异常：在灶具开启期间，kitchen_temp_sensor 的读数在 19:25 突然飙升至 3050 (约 30.5°C)，随后在 19:35 再次飙升至 3220 (约 32.2°C)，之后迅速恢复正常室温 (~22.7°C)。这种剧烈的、非线性的温度跳变通常不是缓慢加热导致的，而是由于热源（灶具）直接辐射或热气流导致局部传感器过热，或者是传感器本身因高温/故障产生的错误读数。结合灶具未关的状态，这强烈暗示了潜在的火情或极端高温环境。",

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。

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",

    "1. 识别异常模式：日志显示在2026-08-12、13、14的早晨08:00左右，`kitchen_smoke_alarm` 连续三次报告 `SmokeCoAlarm.ContaminationState` 分别为 1 (污染), 2 (污染加剧/故障), 3 (严重污染/故障)。这种连续性的状态升级通常指向设备内部问题（如灰尘堆积、元件老化）或环境长期恶劣，而非偶发的烹饪油烟。",
    "2. 排除真实火灾风险：虽然灶具 (`kitchen_cook_surface`) 在早晨开启，但并未触发烟雾报警器的 `FireAlarm` 或 `COAlarm` 状态（日志中仅记录了 `ContaminationState`）。此外，厨房温度传感器 (`kitchen_temp_sensor`) 读数在正常范围内波动（约24-25摄氏度，即2400-2500单位），没有出现火灾时常见的急剧升温。如果存在真实火情，温度应显著高于环境温度，且会触发更高级别的警报。",
    "3. 结合住户行为分析：独居老人在早晨使用灶具是正常的生活习惯（早餐准备）。然而，烟雾报警器在无人持续监控的情况下频繁报错，可能导致老人忽视真正的危险信号（警报疲劳），或者因担心误报而不敢使用明火，影响生活质量。",
    "4. 综合判断：由于缺乏真实的火灾特征（高温、CO浓度、火焰检测），且故障状态具有高度重复性和特定时间点（早晨做饭前/中），判定为传感器本身的硬件故障或需要深度清洁维护，属于 `sensor_malfunction`。"

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
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": [

    "关键证据2"
  ],
  "recommended_actions": [

    "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。

    "2. 温度异常趋势分析：从 01:20 到 04:55，客厅温度传感器读数从 23.06°C 持续攀升至约 24.29°C（注意：Matter协议中温度值通常以厘氏度记录，即除以100为实际摄氏度）。虽然绝对数值看似不高，但在凌晨无人活动（所有occupancy_sensor均为0）且无空调运行迹象（空调未出现在状态变化中，仅温度传感器上报）的情况下，室内温度持续上升是不正常的。",
    "3. 排除误报可能性：通常夜间温度应随室外降温而降低或保持恒定。全屋多个房间（客厅、主卧、儿童房、厨房）温度同步缓慢上升，结合厨房烟雾报警，强烈暗示存在隐蔽的热源或火源正在释放热量和烟雾，导致环境温度升高。",
    "4. 综合判断：烟雾报警是直接的火灾证据，伴随的非自然升温进一步证实了热源的持续存在，属于高风险的安全事件。"

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。
