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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常情况，设备日志显示住户作息规律，环境参数正常。",
  "reasoning": [
    "1. **活动模式分析**：跨天摘要显示客厅(living_room)、卧室(bedroom)和厨房(kitchen)的活动计数在三天内保持高度稳定（例如客厅均为210-212次），符合独居老人规律的生活节奏。没有发现长时间无活动的异常静默期（abnormal_inactivity）或深夜突发的高频活动。",
    "2. **时间序列逻辑**：每日早晨05:50-07:30期间，卫生间、卧室、厨房的运动传感器依次触发，伴随灯光开启（如06:02厨房灯亮），这是典型的起床、洗漱、准备早餐的晨间例行程序。晚上23:38-23:53客厅有活动，随后进入夜间静止状态，符合正常的就寝前活动。",
    "3. **环境与设备状态**：温度读数随时间缓慢变化（从凌晨~24.5°C升至上午~25.3°C），符合自然升温规律，无剧烈波动暗示传感器故障(sensor_malfunction)。门锁仅在早晨07:04左右有一次手动开锁记录，且随后玄关有人活动，未见非法入侵(intrusion)迹象。",
    "4. **关键设备检查**：重点关注的kitchen_light和living_room_occupancy均按预期工作。厨房灯在有人活动时开启，客厅 occupancy 传感器准确反映了人员进出。未发现烟雾报警器报警、漏水检测器触发或灶具无人看管(unattended_cooking)的风险信号。"
  ],
  "key_evidence": [
    "跨天活动计数稳定：Living Room (210/212/210), Bedroom (241/240/243), Kitchen (239/240/240)，表明生活规律一致。",
    "晨间活动链条完整：05:50 Bathroom Occupancy -> 06:02 Kitchen Light On -> 06:07 Kitchen Occupancy，符合早起做饭逻辑。",
    "温度数据平稳：Living Room Temp 从 05:15 的 24.51°C 逐步上升至 08:10 的 25.42°C，无突变。",
    "门锁操作正常：仅 07:04 出现一次 Manual Lock Operation，与住户出门/回家习惯相符，无异常频繁尝试。"
  ],

    "继续保持当前监控策略，无需干预。",

    "推理步骤 3: 对比后续两天日志，2026-08-16 出现关键异常：厨房温度传感器在 06:29 报告值为 None（数据丢失/故障），随后恢复并继续显示高温（25.0°C+）。对于独居老人家庭，传感器突然失效且无法读取真实温度是极高风险信号，可能意味着传感器被遮挡、损坏，或者现场发生了导致传感器无法工作的火灾/过热事件。",
    "推理步骤 4: 综合判断，连续三天厨房区域呈现‘温度异常升高 + 传感器间歇性故障’的模式，且缺乏正常的烹饪行为支撑，高度疑似灶具失控、电路短路引发的早期火灾风险，或传感器本身因高温损坏导致的误报/漏报。"

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。

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。

    "1. 分析时间序列：在20:02时，入户门锁状态变为2（通常代表解锁或已解锁），紧接着在20:03入户门传感器状态变为False（通常代表门被打开/非闭合状态），随后在20:04玄关灯开启。这一连串动作（开锁->开门->开灯）构成了非常典型的用户回家回家的行为模式。",
    "2. 检查异常指标：虽然日志中显示所有房间的运动传感器（包括入口）在20:00-20:30期间均为0（无人），但这可能是由于运动传感器存在检测延迟、灵敏度设置问题，或者用户进入后迅速移动出了传感器覆盖范围。然而，门锁和门磁传感器的物理状态变化是更直接的入侵证据，且其变化顺序合理，未出现“门开但锁未解”或“锁解但门未开”等矛盾情况。",
    "3. 综合判断：没有发现暴力破解、尾随、长时间未关门或其他可疑迹象。结合晚上8点的时间点，这极有可能是住户正常下班回家的情景，因此判定为正常事件。"

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。

    "3. 排除异常模式：虽然系统在 14:06 触发了玄关灯 (entrance_light) 开启，但这可能是由于住户在屋内移动导致玄关区域的光线变化、或者住户在门口附近操作了智能场景（如回家模式），亦或是传感器误触发。鉴于门是锁住的且住户在家，这不属于入侵威胁。卫生间传感器的间歇性 0 值符合正常如厕或短暂离开行为。",

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。

    "1. 分析入户门操作序列：07:19:15 门锁执行上锁操作（LockState=2），随后门磁显示关闭（False）；07:19:21 门锁执行解锁操作（LockState=1），门磁显示开启（True）。这通常对应住户出门后未立即关门或检查门锁，或者在门口短暂停留整理物品，属于正常的人类行为延迟，并非非法入侵尝试。",
    "2. 分析后续状态变化：08:02:00 门锁再次变为锁定状态（LockState=2）且门磁为关闭（False），表明住户最终完成了关门和上锁动作。08:03:00 门锁状态变为未锁定（LockState=1），这可能是智能锁的自动重锁功能未启用，或者住户在门外确认安全后手动/自动解除锁定状态以便下次进入，或者是日志记录的是‘当前状态’而非‘操作事件’，结合上下文，这更像是离家后的状态保持。",
    "3. 结合 occupancy 传感器数据：07:19 至 08:19 期间，玄关运动传感器多次触发（Occupancy=1），但其他房间（客厅、卧室、卫生间）在 07:30-08:00 期间均显示无人（Occupancy=0）。这种‘玄关有人活动，全屋其他区域无人’的模式，高度符合住户正在准备出门或刚出门在玄关处活动的特征。",
