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
以下是过去一段时间的设备活动记录。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",

    "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。

  "confidence": "medium",
  "threat_type": "behavioral_anomaly",

  "key_evidence": [
    "入户后缺少常见过渡动作",
    "直接切到卧室活动",
    "偏离既往居家路径"
  ],

  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示正常的家庭晚间活动模式，包括住户回家、开启灯光空调及门锁操作，未发现安全威胁。",
  "reasoning": [
    "时间线分析：事件发生在 2026-08-17 傍晚至夜间（17:36 - 18:25），符合典型的下班回家时间段。",
    "行为逻辑验证：前门接触传感器先变为 False（开门），随后在 17:58 和 18:20 分别记录了手动上锁操作（LockOperationType=1）和状态变化，表明住户正常进出并锁门。",
    "环境状态确认：客厅运动传感器在 17:58 检测到有人进入，随即开启了灯光和空调，且多个房间的温度传感器读数（约 23°C）处于合理范围，无异常高温或设备故障迹象。",
    "排除误报：虽然温度值以毫开尔文（mK）为单位显示为 2300+，换算后约为 23°C，属于正常室温；所有设备联动（进门->开灯/开空调->锁门）符合预设的自动化场景或用户习惯。"
  ],
  "key_evidence": [
    "front_door_lock 在 17:58:00 记录到 'LockOperation(LockOperationType=1, OperationSource=Manual)' 表示手动上锁。",
    "living_room_occupancy 在 17:58:05 由 0 变为 1，紧接着 living_room_light_1 和 living_room_ac 被激活，符合回家场景。",
    "temperature_sensor 读数稳定在 2300-2380 mK (约 23°C)，未出现超出正常范围的漂移或突变。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，当前系统运行正常。",
    "建议定期查看此类归家日志，确保自动化场景（如离家模式、回家模式）按预期执行。"
  ]

## 任务
以下是过去一段时间的设备活动记录。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",

    "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。

  "threat_description": "厨房温度传感器数据严重异常，数值远超物理可能范围且呈现非自然线性增长，疑似传感器故障或信号干扰。",
  "reasoning": [
    "推理步骤 1: 分析厨房温度传感器 (kitchen_temp_sensor) 的数据流。从 18:00 的 2386 mK (约 23.8°C) 开始，数值在极短时间内（15 分钟内）持续单调递增：2443 -> 2508 -> 2574 -> 2649 -> 2708 -> 2700 -> 2657 -> 2587。",
    "推理步骤 2: 评估数值的物理合理性。Matter 协议中温度通常以毫开尔文 (mK) 为单位。2708 mK 约为 23.9°C，看似正常；但结合上下文，该数值在 18:20 达到峰值 2708 后并未随烹饪开启而合理上升，反而在 18:52 开启灶具后数值波动剧烈且逻辑混乱。更关键的是，若单位解读为摄氏度直接上报（某些设备实现错误），则 2708°C 意味着火灾，但这与周围房间稳定的 ~23°C 读数矛盾。最可能的解释是传感器内部 ADC 溢出、校准丢失或受到强电磁干扰导致读数漂移至无效高位/低位区间。",
    "推理步骤 3: 交叉验证与其他设备状态。当厨房温度显示异常时，其他房间（客厅、主卧等）的温度传感器读数稳定在 22-23°C 之间，符合常理。同时，入户门锁操作和人员进出记录正常，排除了入侵导致的极端环境变化。这种‘单点设备’出现违背物理定律的连续异常读数，确认为传感器自身故障而非环境威胁。",
    "推理步骤 4: 关联事件分析。虽然用户在 18:52 开启了灶具，但正常的烹饪升温不会导致传感器读数瞬间跳变至数千度或呈现无规律的锯齿状波动。传感器在 18:53 甚至短暂返回 None，进一步证实了数据采集链路的不稳定性。"
  ],
  "key_evidence": [
    "kitchen_temp_sensor 在 18:00 至 18:20 期间数值从 2386 线性攀升至 2708，随后在开启灶具后出现剧烈震荡和归零现象。",
    "同一时间段内，全屋其他区域温度传感器读数稳定在 22-23°C 的正常范围内，形成鲜明对比。",
    "传感器读数变化速率和幅度不符合任何已知热源（如空调、阳光、烹饪）的热力学特征。"
  ],
  "recommended_actions": [
    "立即检查厨房温度传感器的物理连接及供电情况，排除接触不良或电源干扰。",
    "尝试重置厨房温度传感器或将其从 Matter 网络中移除并重新配对，以恢复固件校准。",
    "在修复前，建议人工定期手动测量厨房温度，以确保烟雾报警器等安全联动设备能基于真实环境做出正确判断。"

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",

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",

## 任务
请从下面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",
    "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。

  "confidence": "medium",
  "threat_type": "behavioral_anomaly",
  "threat_description": "设备使用频率突然翻倍",
  "reasoning": [

    "设备操作逻辑正常：厨房灶具 (cook_surface) 开启后不久关闭，随后洗碗机启动，灯光随人员移动自动开关，空调系统运行，所有设备状态变化均符合预期的人为操作或自动化场景逻辑。",
    "传感器数据一致：温度传感器读数稳定下降（从约 23.4°C 降至 22.6°C），与空调开启及夜间气温降低趋势一致；未出现传感器卡死、漂移或丢失信号等故障迹象。"
  ],
  "key_evidence": [
    "多房间 occupancy 传感器在同一时间段内连续报告 '1' (有人)，证明是多名家庭成员在场。",
    "厨房灶具 (OnOff=True) 和洗碗机 (OperationalState=1) 的操作顺序符合烹饪流程，且后续有灯光和温度变化响应。",
    "温度传感器数值随时间呈现合理的物理降温曲线，未见异常跳变或静止值。"
  ],

## 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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "behavioral_anomaly",
  "threat_description": "设备使用频率突然翻倍",
  "reasoning": [
    "推理步骤1: 同一设备短时间高频重复使用",
    "推理步骤2: 频率显著高于普通居家行为",
    "推理步骤3: 更像异常强迫式操作"
  ],
  "key_evidence": [
    "同一设备短时间高频重复使用",
    "频率显著高于普通居家行为",
    "更像异常强迫式操作"
  ],
  "recommended_actions": [
    "标记为异常设备交互模式，建议持续观察。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示独居老人在傍晚时段正常的居家活动模式，无安全威胁或异常行为。",
  "reasoning": [
    "时间合理性分析：所有事件集中在 17:00 至 19:20 之间，符合独居老人傍晚回家、休息及晚间活动的正常作息规律。",
    "设备状态一致性：客厅灯光（living_room_light）在有人出现时开启，无人时关闭，且与运动传感器（occupancy_sensor）的状态变化高度同步，表明自动化逻辑运行正常，非误报或故障。",
    "环境数据验证：温度传感器读数（如 2369 mK ≈ 23.7°C）处于舒适且安全的室内范围，未出现极端高温或低温导致的设备损坏风险；多房间温度波动平缓，符合空调调节后的自然热交换过程。",
    "人员流动逻辑：入户门和玄关区域的 occupancy 信号频繁触发，随后其他区域（厨房、卧室、客厅）依次有人活动，形成了完整的“进门 - 活动 - 休息”闭环，排除了入侵或尾随的可能性。"
  ],
  "key_evidence": [
    "17:02 客厅检测到人员后，19:00 左右再次检测到人员并伴随灯光开关操作，符合日常起居习惯。",
    "温度传感器数值稳定在 21-24°C 区间，无突变或漂移现象。",
    "各房间 occupancy 传感器状态转换流畅，无长时间静止后突然多人进入等异常模式。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",
    "建议定期校准温度传感器以确保长期准确性。"
  ]
}

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",
  "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": true,
  "confidence": "medium",
  "threat_type": "behavioral_anomaly",
  "threat_description": "设备使用频率突然翻倍",
  "reasoning": [
    "推理步骤1: 同一设备短时间高频重复使用",
    "推理步骤2: 频率显著高于普通居家行为",
    "推理步骤3: 更像异常强迫式操作"
  ],
  "key_evidence": [
    "同一设备短时间高频重复使用",
    "频率显著高于普通居家行为",
    "更像异常强迫式操作"
  ],
  "recommended_actions": [
    "标记为异常设备交互模式，建议持续观察。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "家庭整体安全状况正常，设备运行符合预期住户活动模式，未发现入侵、火灾或设备故障迹象。",
  "reasoning": [
    "时间线分析：日志显示从 17:00 到 20:15 期间，入户门（entrance）和客厅（living_room）的 occupancy 传感器多次检测到人员进出和活动，且门锁状态在 18:19 正常解锁后保持开启，随后有规律的人员流动，符合晚间回家及居家活动的正常行为模式。",
    "环境数据验证：温度传感器读数（如 living_room_temp_sensor 从 23.6°C 逐渐下降至 22.6°C）变化平缓且逻辑连贯，空调系统（living_room_ac）在有人进入时启动制冷，无人时关闭，温控逻辑正常，无过热或异常波动。",
    "关键设备状态：厨房灶具（cook_surface）在 19:25 自动关闭，洗碗机（dishwasher）正常运行，烟雾报警器未触发报警信号；所有窗户和门的接触传感器状态与 occupancy 数据一致，未发现门窗被非法闯入或意外打开的情况。",
    "排除误报：虽然存在短暂的 sensor_drift 可能性（如 kitchen_temp_sensor 偶尔返回 None），但结合其他房间温度数据和后续恢复正常的读数，可判定为临时通信延迟而非硬件故障，不影响整体安全评估。"
  ],
  "key_evidence": [
    "入户门锁在 18:19 正常解锁，随后伴随连续的 occupancy 检测事件，表明是合法住户回家。",
    "客厅空调根据 occupancy 状态自动启停，温度控制在合理范围内（22-24°C），无异常升温或断电现象。",
    "厨房灶具在 19:25 自动关闭，且无烟雾报警器触发记录，排除了烹饪安全隐患。"
  ],
  "recommended_actions": [
    "继续保持当前智能家居自动化策略，无需调整。",
    "建议定期检查厨房漏水传感器和主卫漏水传感器的电池电量，确保长期可靠性。"
