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
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。

{
  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",

  "threat_type": "health_concern",
  "threat_description": "独居老人在凌晨时段（02:18 - 05:38）出现长时间无活动且卧室灯光异常开启，随后在清晨再次开灯，存在夜间跌倒、突发疾病或被困风险。",
  "reasoning": [
    "推理步骤 1: 时间窗口分析。日志显示在 02:10 至 05:38 之间，所有房间（living_room, bedroom, kitchen, bathroom, entrance）的 OccupancySensing.Occupancy 持续为 0，表明屋内无人移动超过 3.5 小时。对于独居老人而言，这是极不正常的静默期。",
    "推理步骤 2: 行为逻辑矛盾。在 02:18，bedroom_light 被打开（OnOff.OnOff = True），但此时 occupancy_sensor 仍报告为 0。通常人进入房间会触发传感器，或者人离开后灯会自动关闭/延时关闭。这种‘灯亮但无人’的状态可能意味着：(a) 老人跌倒在地无法起身触发传感器；(b) 老人意识不清操作了开关；(c) 传感器故障未检测到人体。",
    "推理步骤 3: 后续状态确认。直到 05:38 才再次有 bedrooom_light 开启事件，中间长达 3 小时无任何 occupancy 变化或设备交互。结合独居老人的背景，长时间静止伴随异常的灯光操作，高度疑似健康危机（如中风、心脏病发作导致倒地）或意外跌倒。",
    "推理步骤 4: 排除其他威胁。厨房灶具、烟雾报警器、漏水传感器均无异常报警记录，温度读数虽有波动但在合理范围内（约 22-24°C），排除了火灾、煤气泄漏或水管爆裂等物理环境威胁。"
  ],
  "key_evidence": [
    "02:18 至 05:38 期间，全屋运动传感器持续报告 Occupancy=0，形成超 3 小时的静默期。",
    "02:18 和 05:38 两次出现 bedroom_light 开启事件，但两次开启之间及第一次开启时均无对应的人员移动检测信号。",
    "跨天摘要显示该时间段内各房间活动量极低（bathroom=61 次，远低于白天水平），印证了夜间活动的缺失。"
  ],
  "recommended_actions": [
    "立即通过家庭监控摄像头查看卧室及客厅画面，确认老人位置及状态。",
    "尝试远程联系老人或其紧急联系人，询问情况。",
    "若联系不上且视频确认异常，立即拨打急救电话并通知家属。",
    "检查卧室运动传感器是否因遮挡或故障导致误报，必要时进行校准或临时移除障碍物。"

## 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",
  "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

    "1. 活动模式分析：日志显示住户在早晨7:00-9:00期间活跃（厨房、客厅、卧室均有 occupancy 记录），随后活动减少，夜间23:46-23:50仍有活动记录，符合老年人早起晚睡或作息规律的常态，未发现长时间无活动的健康风险（abnormal_inactivity）。",
    "2. 门锁与入侵检查：三天内仅在早晨8:27、8:34、8:34左右出现手动开锁记录（Manual Lock Operation），且伴随玄关/入户门运动传感器触发，这符合住户出门或回家的正常行为。未检测到非授权时间的非法闯入或异常锁操作。",
    "3. 环境安全监控：虽然日志中主要展示了温度读数（如2509即25.09°C）和占用情况，但未出现烟雾报警器（smoke_co_alarm）或漏水传感器（water_leak_detector）的报警事件。厨房灶具（cook_surface）虽在厨房有人时存在，但无异常高温或持续无人看管的证据（通常需结合灶具状态和长时间无移动判断，此处仅展示占用，且时间较短，属正常烹饪时段）。",
    "4. 传感器状态：温度读数随时间缓慢变化，符合室内热惯性特征；占用传感器在人员移动时正确触发，无明显的卡死（stuck）或漂移（drift）迹象。"
  ],
  "key_evidence": [
    "连续三天早晨8:30左右的手动开锁记录与玄关运动传感器联动，符合正常出行习惯。",
    "全天各房间占用传感器交替触发，无超过24小时的完全静止区域（除睡眠时段外），排除跌倒或昏迷风险。",
    "无烟雾、一氧化碳或漏水报警事件记录。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需紧急干预。",
    "建议定期校准温度传感器以确保读数准确性，尽管目前数据看起来正常。"

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",
  "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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常情况，设备日志显示住户活动规律，环境参数正常。",
  "reasoning": [
    "1. 活动模式分析：日志显示住户在上午10:30至下午14:00之间活跃，主要分布在客厅、厨房和卧室。这种日间活动模式符合独居老人的正常作息（如午休后起床、准备午餐等），未发现长时间无活动的健康风险或夜间异常入侵迹象。",
    "2. 烹饪安全评估：虽然重点关注的 kitchen_light 多次开启，且厨房灶具 (cook_surface) 在8月6日11:36有状态记录，但并未出现‘灶具开启后长时间无人’或‘烟雾报警器触发’的情况。厨房温度传感器读数稳定（约25°C左右，Matter协议中通常单位为0.01摄氏度，即25.52°C），未见异常升温，表明烹饪行为受控且安全。",
    "3. 设备状态一致性：所有运动传感器 (occupancy_sensor) 的触发与住户在房间的活动逻辑一致（例如进入厨房前玄关或客厅有活动）。门窗传感器和窗帘状态未显示非法开启或异常关闭。没有证据表明存在传感器故障（如持续触发）或执行器卡死。"
  ],
  "key_evidence": [
    "厨房温度传感器读数稳定在2500-2550之间（约25-25.5°C），无过热迹象。",
    "未检测到 smoke_co_alarm 触发事件。",
    "住户活动集中在白天时段（10:00-14:00），符合正常生活规律。",
    "厨房灶具仅在特定时间段短暂操作，且伴随人员活动，无无人看管迹象。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需紧急干预。",
    "建议定期校准温度传感器以确保读数准确性（尽管当前数据看起来正常）。"
  ]
}
```

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_drift",
  "threat_description": "客厅温度传感器读数异常偏高且数值格式疑似错误（2500+），导致系统误判环境温度，可能掩盖真实火灾风险或造成空调控制失效。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，从 2026-08-04T11:00:00 开始，living_room_temp_sensor 的 MeasuredValue 持续在 2500 以上（如 2546, 2551, 2531 等）。",
    "推理步骤 2: 对比同一时间段内其他房间的温度传感器数据（bedroom_temp_sensor 约为 2400-2430，kitchen_temp_sensor 约为 2500-2550），虽然厨房因烹饪可能较热，但客厅作为主要活动区域，其温度读数与卧室相比存在巨大且不合常理的偏差（通常室内温差不会超过 10-15 度，除非极端情况）。",
    "推理步骤 3: 考虑到 Matter 协议中温度单位通常为摄氏度 (°C)，正常室温应在 20-30°C 之间。读数 2546°C 显然超出了物理极限，极有可能是传感器硬件故障、校准漂移或数据传输错误（例如将毫伏值或其他单位误传为摄氏度，或者数值本身发生了溢出/位翻转）。这种持续的异常高读数会导致智能家居系统错误地认为室内过热，从而可能阻止空调制冷（如果逻辑是防止过热）或在真正发生火灾时无法通过温度骤升来触发警报，对独居老人构成安全隐患。",
    "关键证据": [
      "2026-08-04T11:00:00 living_room_temp_sensor 报告 2546，随后多次维持在 2500+ 区间。",
      "同期 bedroom_temp_sensor 读数稳定在 2400-2430 区间，两者差异过大不符合物理规律。",
      "该异常模式连续出现在三天（08-04, 08-05, 08-06）的上午时段，具有持续性而非瞬时干扰。"
    ],
    "recommended_actions": [
      "立即检查并更换客厅温度传感器硬件，或重置设备以排除临时性通信错误。",
      "暂时手动监控客厅实际温度，确保空调系统正常工作，防止老人因高温中暑。",
      "检查烟雾报警器和空调控制逻辑是否受此异常温度数据影响，必要时进行人工干预。"

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",
  "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。

{
  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",

  ]
}

  "confidence": "high",
  "threat_type": "health_concern",
  "threat_description": "独居老人在凌晨时段出现长时间无活动且室内温度异常升高，存在健康风险或意外滞留的可能性。",
  "reasoning": [
    "推理步骤 1: 时间窗口分析显示，从 02:18 到 05:30（约 3.5 小时），卧室灯被打开，但随后直到 09:36 之前，所有房间（包括客厅、厨房、卫生间）的运动传感器均持续报告无人状态（Occupancy=0）。对于独居老人而言，深夜起床开灯后长时间未返回卧室或离开房间是极不寻常的行为模式。",
    "推理步骤 2: 环境数据异常，在此期间客厅和厨房的温度传感器读数持续攀升并超出正常舒适范围（例如 04:00 时客厅温度达到 2402 mK 即 24.02°C，05:30 时厨房达到 2376 mK 即 23.76°C，且趋势仍在上升）。在夜间无人活动的情况下，空调系统未能有效调节温度或设备故障导致过热，增加了安全隐患。",
    "推理步骤 3: 结合住户画像（独居老人），这种“夜间活动 - 长时间静止 - 高温环境”的组合高度疑似老人突发身体不适（如中风、跌倒昏迷）导致无法移动，或者因睡眠障碍/认知问题在夜间游荡后迷失方向。虽然 05:59 有短暂的卫生间占用记录，但这可能是家人短暂进入查看，不能排除老人仍处于危险状态的风险。"
  ],
  "key_evidence": [
    "02:18 至 05:30 期间，除一次短暂的卫生间占用外，全屋运动传感器连续 3.5 小时报告无人状态。",
    "同一时间段内，客厅和厨房温度持续异常升高，最高达 24.02°C，且未见降温迹象。",
    "住户为独居老人，缺乏即时监护，长时间无活动属于高危信号。"
  ],
  "recommended_actions": [
    "立即通过智能家居语音助手或电话尝试联系老人，确认其安全状况。",
    "若联系不上，建议家属或紧急联系人尽快上门查看，或联系社区/急救服务进行核查。",
    "检查空调及温控系统是否正常工作，防止因设备故障导致的极端温度对老人造成二次伤害。"

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
以下是过去 2 天的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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: ..."
  ],
  "key_evidence": [
    "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。

{
  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "当前日志更符合正常模式，不建议报警。",
  "reasoning": [
    "推理步骤1: 正常样本做饭持续 20 分钟左右；异常样本连续两天都只持续约 5 分钟。"
  ],
  "key_evidence": [
    "正常样本做饭持续 20 分钟左右；异常样本连续两天都只持续约 5 分钟。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "threat_description": "这些变化表明存在安全异常。",
  "reasoning": [
    "推理步骤1: 我把本可由正常模式解释的事件误判成了异常。"
  ],
  "key_evidence": [
    "正常样本做饭持续 20 分钟左右；异常样本连续两天都只持续约 5 分钟。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
