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
{
  "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",

  "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。

    "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2026-07-05、07-06和07-07的早晨8:00左右，分别报告了 SmokeCoAlarm.ContaminationState = 1, 2, 3。",
    "2. 分析污染状态含义：在Matter协议及常见智能家居标准中，ContaminationState通常用于指示传感器内部脏污程度或需要维护的状态。数值从1增加到3，且持续三天未消除，强烈暗示这是一个持续的硬件问题（如灰尘堆积、传感器老化）或环境干扰，而非偶发的误报。",
    "3. 排除真实火灾风险：尽管存在传感器故障，但同一时间段内（06:00-09:00），厨房灶具仅在7月6日短暂开启（06:02-06:30），且期间温度传感器读数正常上升后回落，未见剧烈温升；更重要的是，烟雾报警器并未触发报警状态（Alarm State），仅报告污染。这表明当前没有正在发生的火灾，而是安全设备本身处于不可靠状态。",
    "4. 结合住户背景：独居老人对火灾等突发危险的应对能力较弱，依赖可靠的烟雾报警器至关重要。一个处于“污染/故障”状态的报警器可能在真正发生火灾时失效，构成重大安全隐患。"

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。

  "threat_description": "厨房温度传感器在正常烹饪结束后出现严重数据漂移，报告了远超物理可能性的异常高温值（3050°C, 3220°C），且数值在极短时间内剧烈波动，表明传感器故障或通信错误。",
  "reasoning": [
    "推理步骤 1: 分析时间线，用户在 19:20 关闭了灶具 (kitchen_cook_surface OnOff=False)，此时厨房环境应开始降温或保持室温。",
    "推理步骤 2: 检查温度传感器日志，在 19:25 和 19:35 分别记录了 3050 和 3220 的 MeasuredValue。考虑到 Matter 协议中温度通常以 0.01°C 为单位，这代表 30.50°C 和 32.20°C，属于正常范围；但结合上下文其他读数（如 2278=22.78°C）来看，若单位一致，这些数值本身是合理的室温。然而，仔细观察数据序列：19:25(3050) -> 19:30(2286) -> 19:35(2277) -> 19:35(3220)。",
    "推理步骤 3: 重新评估单位假设。如果原始数据是毫摄氏度 (mCelsius)，则 3050 mC = 30.5°C，3220 mC = 32.2°C。但在 19:20 关火后，温度从之前的 22-23°C 跳变到 30°C 再回落到 22°C 再跳到 32°C，这种无规律的剧烈震荡（尤其是同一分钟内两次不同的高位读数）不符合热力学规律。更可能的情况是：设备固件将单位搞错（例如误报为开尔文或其他标度导致数值巨大，或者此处数值本身就是错误的浮点溢出/丢包）。",
    "推理步骤 4: 对比正常行为。正常的烹饪后温度变化应该是平滑下降。这里出现的 3050 和 3220 如果是摄氏度则是绝对不可能存在的（除非发生核爆炸），如果是毫摄氏度则意味着温度在短时间内剧烈且无理由地上下跳动，且伴随同一时刻多次上报不一致的数值，这是典型的传感器数据损坏、固件 Bug 或通信干扰导致的 sensor_malfunction。",
    "推理步骤 5: 风险评估。对于独居老人，虽然 30°C 左右的温度本身不致命，但传感器失效可能导致无法准确监测火灾风险（烟雾报警器依赖温度联动时）或误触发警报，更重要的是，这种数据异常掩盖了真实的设备状态，属于系统可靠性问题。"

## 任务
监控系统标记了潜在异常。请分析下面的日志，判断是否需要采取响应措施，并给出建议。

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
请分析下面的实时设备事件，判断是否需要将其视为异常安全事件。

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",
  "reasoning": [

    "推理步骤2: ...",

    "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。
