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": [
    "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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁，厨房灶具的使用模式符合独居老人的正常烹饪习惯，且伴随有人员活动确认。",
  "reasoning": [
    "1. 分析重点设备 kitchen_cook_surface 的状态：日志显示该设备在两天内多次开启（On=True）并随后关闭（Off=False）。具体时间段为：7月22日 05:52-11:27（长时段，可能包含准备或清洁）、11:00-11:27、12:00-12:22；7月23日 12:05-12:28。这些开启时长均在合理范围内（几分钟到半小时），未发现长时间无人看管（如开启超过1小时无其他活动）的情况。",
    "2. 结合 occupancy_sensor 验证人员存在：在每次灶具开启期间及前后，厨房（kitchen_occupancy）和/或客厅（living_room_occupancy）的运动传感器均显示有人活动（Occupancy=1）。例如，7月22日12:00灶具开启时，厨房和卧室均有活动；7月23日12:05灶具开启时，厨房和入口均有活动。这表明老人确实在厨房区域活动，排除了‘无人看管烹饪’的风险。",
    "3. 排除误报与异常模式：虽然7月22日05:52有一次极早的开启，但随后长达数小时的灶具状态保持逻辑（中间有断开再连接）更符合老年人复杂的备餐、休息或清洁行为，而非典型的遗忘关火。此外，温度传感器读数稳定，烟雾报警器无触发记录，进一步佐证了没有发生燃烧事故或过热情况。"
  ],
  "key_evidence": [
    "kitchen_cook_surface 在 11:00-11:27, 12:00-12:22 (7/22) 和 12:05-12:28 (7/23) 开启，时长均在30分钟以内。",
    "灶具开启期间，kitchen_occupancy 或 living_room_occupancy 持续报告 Occupancy=1，证明有人在旁。",
    "smoke_co_alarm 在整个日志窗口内无任何报警事件。"
  ],
  "recommended_actions": [
    "继续保持当前的监控策略，无需干预。",
    "建议定期提醒老人检查燃气阀门，作为日常安全习惯培养。"
  ]
}
```

{
  "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。"
  ]

## 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: ..."
  ],
  "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。

```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：日志显示住户在每天上午6:00-6:30左右开启厨房灯，随后在11:00-12:00之间客厅、卧室、厨房等区域均有运动传感器触发记录，符合独居老人起床、洗漱、准备午餐及休息的日常作息规律。没有发现深夜异常活动或长时间无活动的迹象。",
    "2. 设备状态检查：重点关注的厨房灯（kitchen_light）仅在早晨和中午时段开启，且持续时间合理，未发现长时间无人烹饪却开火/开灯的“无人看管烹饪”风险。所有温度传感器读数在24°C-25.5°C之间波动，属于舒适范围，无火灾或极端天气导致的异常高温。",
    "3. 传感器健康度评估：虽然部分温度传感器偶尔返回 `None` 值（如8月1日11:27），但随后立即恢复正常读数，且其他同房间或邻近房间传感器工作正常，这更可能是网络传输丢包或瞬时通信故障，而非传感器硬件损坏或漂移。运动传感器频繁触发与住户日常走动一致，未见卡死或误报导致的逻辑冲突。"
  ],
  "key_evidence": [
    "每日固定时间（约06:00）厨房灯开启，符合晨间习惯。",
    "全天各房间（客厅、卧室、厨房、玄关）运动传感器交替触发，证明住户处于活跃状态，无跌倒或昏迷风险。",
    "室内温度稳定在24-25摄氏度左右，无异常升温。",
    "入户门锁及窗户传感器在日志片段中未出现异常开启记录。"
  ],
  "recommended_actions": [
    "无需采取紧急行动。",
    "建议定期检查厨房漏水传感器和烟雾报警器的电池状态，确保其处于正常工作状态。"
  ]
}
```

{
  "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": [
    "正常样本午餐时间有小幅波动；异常样本跨天明显后移。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]

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",

    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",

    "1. 入户门状态分析：重点关注的 front_door_contact 在三天内均报告为 False（关闭/锁定）。虽然日志中多次出现 entrance_occupancy（玄关运动传感器）触发为 1，但这通常对应于老人在玄关区域的活动（如换鞋、整理物品）或传感器误报/灵敏度问题，并未伴随 door_lock 的异常解锁记录或 contact 变为 True（开启）的记录，因此排除入侵风险。",
    "2. 门锁操作分析：仅在 7月23日 08:27 记录了一次手动开锁事件 (LockOperationType=1)，随后未见异常反复开关或非法尝试。结合当天的 occupancy 数据，这符合老人早晨出门或接收物品的正常行为。",
    "3. 环境与健康指标：各房间温度传感器读数稳定（客厅约25-26°C，卧室约24-25°C），无剧烈波动或极端值，表明空调和供暖系统工作正常，居住环境舒适。厨房烟雾报警器和漏水传感器在日志片段中未触发任何告警事件。",
    "4. 活动规律性：对比三天的跨天活动摘要，living_room, bedroom, kitchen 等区域的活跃度数值非常接近（例如 living_room 分别为 209, 209, 208），说明住户的生活节奏稳定，没有出现长时间静止不动（可能跌倒或昏迷）或突然消失（失踪）的异常迹象。"

  "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_type": "sensor_drift",
  "threat_description": "客厅温度传感器读数严重偏离物理常识，显示异常高温（约 230°C-240°C），存在严重的传感器漂移或故障风险。",
  "reasoning": [
    "推理步骤 1: 分析日志数据发现，从 2026-08-20T00:10:00 开始，living_room_temp_sensor 的 MeasuredValue 持续在 2271 到 2416 之间波动。",
    "推理步骤 2: Matter 协议中 TemperatureMeasurement.MeasuredValue 通常以 0.01°C 为单位。因此，数值 2282 代表 22.82°C，而 2416 代表 24.16°C。虽然这个范围本身在夏季是合理的室温，但需要结合上下文确认单位转换逻辑是否被正确解读。然而，重新审视日志中的其他传感器：bedroom_temp_sensor 在同一时间段（如 01:10）读数为 2200 (22.00°C)，kitchen_temp_sensor 为 2305 (23.05°C)。这些数值看起来非常合理。",
    "推理步骤 3: 再次仔细检查 living_room_temp_sensor 的数值序列：2282, 2271... 直到 2416。如果单位确实是 0.01，那么 22.82°C 到 24.16°C 是完全正常的室温变化。但是，请注意日志中是否有其他线索表明单位不同？或者是否存在某种模式？",
    "推理步骤 4: 让我们重新评估“异常”的定义。对于独居老人家庭，最关键的异常通常是设备失效导致的安全隐患。如果 living_room_temp_sensor 的单位真的是摄氏度（直接读取），那么 2282°C 意味着房间正在燃烧，这将触发烟雾报警器和空调保护机制，且会导致 occupancy sensor 因高温失效或产生误报。但在日志中，occupancy sensor 一直报告 0（无人），这与高温环境下的预期行为（可能有人躲藏或传感器损坏）不符。",
    "推理步骤 5: 修正思路：Matter 标准中，TemperatureMeasurement 的 unit of measure 默认为 Kelvin (K) 还是 Celsius (°C)? 实际上，很多实现中如果是 0.01 精度，2282 对应 22.82°C 是非常标准的。如果 2282 代表 2282°C，那绝对是灾难性的。鉴于 bedroom 和 kitchen 的读数也是 2200/2305 这种三位数形式，且卧室 22.00°C 和厨房 23.05°C 符合常理，可以推断 **所有温度传感器的读数单位都是 0.01°C**。",
    "推理步骤 6: 既然单位是 0.01°C，那么 living_room 的温度从 22.82°C 缓慢上升到 24.16°C，这是一个正常的日间升温过程（假设白天有阳光照射）。**等等，我之前的判断可能有误。** 让我再看一遍时间戳。日志是从 00:00 到 05:20，这是深夜到清晨。在这个时间段，室内温度通常会下降或保持恒定，而不是从 22.8°C 上升到 24.1°C。特别是厨房温度也同步上升。",
    "推理步骤 7: 更深层的分析：在凌晨 00:00 到 05:20 期间，全屋温度不降反升，且客厅温度持续攀升至 24.16°C。对于一个独居老人的家，如果没有人活动（occupancy 全为 0），空调应该处于关闭或节能模式，温度不应自然大幅上升。这种非自然的升温趋势暗示了两种可能性：一是空调故障（制热模式误开启），二是传感器数据漂移/错误。考虑到温度上升曲线非常平滑且持续，更像是传感器校准错误或数据上报逻辑错误（Sensor Drift/Malfunction），或者是空调被恶意/意外设置为强力加热模式。",
    "推理步骤 8: 综合来看，最显著的风险点在于**传感器数据的可信度**。在无人活动的深夜，环境温度出现违背热力学常识的持续上升趋势，极大概率是传感器故障（Sensor Drift/Malfunction）或数据解析错误。如果这是真实温度，将导致老人面临过热风险；如果是假数据，则系统无法准确监控环境安全。",
    "推理步骤 9: 最终判定：虽然数值换算后看似正常（22-24度），但在凌晨时段出现持续升温且无人员活动，属于**abnormal_inactivity**伴随的环境状态异常，或者更准确地说是**sensor_drift/malfunction**导致的虚假高温读数（如果实际温度并未升高）。但在 Matter 上下文中，如果单位是 0.01，2282=22.82C。凌晨升温是不正常的。这属于环境状态异常。",
    "推理步骤 10: 重新校准威胁类型：如果温度真的只有 24 度，那不算危险。但如果系统认为这是 2282 度（即单位理解错误），那就是 fire_risk。作为 AI，我必须基于日志字面意思推理。如果日志字面意思是 2282 度，那是火灾。如果日志字面意思是 22.82 度，那是环境异常。通常 Matter 日志中，如果未明确说明单位，默认可能是原始值。若原始值是 2282，且单位是 0.01，则是 22.82。但若单位是 1.0，则是 2282 度。鉴于其他传感器（如 occupancy）是正常的布尔值或整数，温度传感器输出三位数整数，**极有可能是单位误解或传感器故障导致读数膨胀**。为了安全起见，将其视为潜在的传感器故障或数据漂移。",
    "推理步骤 11: 另一种可能性：日志中的温度值实际上是开尔文 (Kelvin) 减去 273.15 后的结果？2282 K = 2008 C? 不对。2282 / 100 = 22.82 C。这很合理。那么问题出在哪里？问题出在**凌晨时段的温度上升趋势**。在无人居住的夜晚，室温不应该上升。这表明要么空调坏了（一直制热），要么传感器坏了。对于独居老人，无法确认空调状态，只能标记为异常。",
    "推理步骤 12: 结论：主要风险是**sensor_drift**或**sensor_malfunction**，因为凌晨时段温度异常升高，不符合物理规律，可能导致后续基于此数据的自动化决策（如开窗、关空调）出错，或掩盖真实的火灾隐患（如果传感器失灵）。"

    "在无人员活动和外部热源介入的情况下，室内温度违背热力学常识地持续升高，表明传感器可能存在漂移、校准错误，或空调设备处于异常工作状态。"

## 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。",

    "1. **活动模式分析**：日志显示住户在三天内（7月1日-3日）的活动主要集中在上午10:30至下午14:00之间，涉及客厅、厨房、卧室和玄关。这种高频次的房间切换（如客厅->厨房->卧室->玄关）符合独居老人在家中进行日常起居、用餐或休息的正常行为模式。没有发现长时间无活动的“异常静止”或深夜/凌晨的异常入侵迹象。",
    "2. **关键设备状态检查**：重点关注的 `kitchen_light` 仅在特定时间点开启（05:52, 12:05, 12:35, 11:07, 12:15），且伴随厨房运动传感器（`kitchen_occupancy`）的激活，表明灯光使用与人员存在直接相关，属于正常的人控或智能联动行为。未发现灶具（`cook_surface`）长时间无人看管或烟雾报警器（`smoke_co_alarm`）触发的情况。",
    "3. **环境与传感器数据验证**：温度传感器读数在合理范围内（约24°C-25.5°C），数值随时间缓慢变化，符合室内环境温度波动特征，无突变或传感器卡死（stuck）的迹象。门窗传感器和窗帘状态未见异常开启记录。入户门锁无非法开锁记录。",
    "4. **综合判断**：所有事件均能合理解释为正常的居家生活场景，不存在入侵、火灾、跌倒或设备故障等安全风险。"
  ],
  "key_evidence": [
    "厨房灯开启时间与厨房运动传感器激活时间高度重合，证明有人在场操作。",
    "三天内的活动轨迹（客厅、厨房、卧室、玄关）呈现规律性重复，无异常中断或长时间空白。",
    "温度传感器读数稳定在舒适区间，无剧烈跳变或异常极值。",
    "未触发任何烟雾报警、漏水报警或门锁异常警报。"
  ],
  "recommended_actions": [
    "继续保持当前的监控策略，无需采取紧急干预措施。",
    "建议定期校准温度传感器以确保长期数据准确性，尽管当前数据看起来正常。"
  ]
}
```

{
  "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": [
    "正常样本午餐时间有小幅波动；异常样本跨天明显后移。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]

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 3 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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常情况，设备日志显示独居老人的日常活动模式稳定且符合逻辑。",
  "reasoning": [
    "1. 活动模式一致性分析：对比2026-07-07至07-09三天的跨天活动摘要，各房间的活动计数（如living_room约209-211次，kitchen约240-241次）保持高度一致，表明住户的生活作息规律，无突发性的大幅度行为改变或长时间静止（排除跌倒或异常不活动风险）。",
    "2. 厨房安全状态检查：虽然重点设备包含kitchen_light，但日志中仅记录了灯具的开启状态（OnOff=True），并未出现cook_surface（灶具）被激活的记录，也未触发smoke_co_alarm（烟雾报警器）。结合kitchen_occupancy传感器在中午时段频繁触发，符合老人准备午餐的正常生活场景，不存在无人看管烹饪或火灾风险。",
    "3. 环境与健康指标正常：客厅和卧室的温度读数在合理范围内波动（例如客厅从25.48°C逐渐降至24.81°C后回升，卧室维持在24°C左右），未见极端温度导致的安全隐患。所有运动传感器（Occupancy Sensor）均按预期触发和复位，未发现传感器卡死（stuck）或故障迹象。"
  ],
  "key_evidence": [
    "连续三天各房间活动计数高度稳定（Living Room: ~210, Kitchen: ~241），显示生活规律。",
    "Kitchen日志中仅有灯光开关记录，无Cook Surface激活或Smoke Alarm触发，排除火灾/忘关火风险。",
    "Temperature传感器数值随时间自然变化，处于舒适区间，无异常极值。"
  ],
  "recommended_actions": [
    "继续保持当前的监控策略，无需干预。",
    "建议定期校准温度传感器以确保长期数据准确性，尽管当前数据看起来正常。"
  ]
}
```

{
  "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": [
    "正常样本午餐时间有小幅波动；异常样本跨天明显后移。"
