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": true,
  "confidence": "medium",
  "threat_type": "child_safety",
  "threat_description": "家长睡后儿童使用厨房电器",
  "reasoning": [
    "推理步骤1: 深夜厨房灯和灶具被打开",
    "推理步骤2: 儿童房活动状态变化",

  ],
  "key_evidence": [

  ],

  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "儿童房温度传感器报告异常数值（2246-2259），远超正常物理温度范围，且伴随高频波动，疑似传感器故障或数据漂移。",
  "reasoning": [
    "推理步骤 1: 分析日志发现 kids_room_temp_sensor 在 21:20 至 23:20 期间持续上报温度值，但数值均在 2241 到 2265 之间。",
    "推理步骤 2: 对比同一时间点的其他房间温度传感器（如 living_room、master_bedroom、kitchen），其读数均在 2240-2265 的合理范围内（约 22.4°C - 22.6°C）。",
    "推理步骤 3: 虽然数值看起来像 22.x 度，但原始数据缺少小数点（例如 2246 而非 22.46），或者该设备配置了错误的单位/缩放因子。考虑到 Matter 协议中温度通常以 0.01 度为单位，2246 代表 224.6°C，这在室内绝对不可能；若代表 22.46°C，则与其他房间一致。然而，结合 'sensor_drift' 和 'sensor_malfunction' 选项，这种非线性的、看似随机的高频跳动（2246->2256->2254...）且数值本身作为整数出现，强烈暗示传感器硬件故障、固件 bug 导致的数据溢出或校准错误，而非真实的温度变化。",
    "推理步骤 4: 尽管 occupancy 显示有人存在，但温度数据的异常模式与正常的热力学行为不符，属于典型的传感器 malfunction 或 drift。"
  ],
  "key_evidence": [
    "kids_room_temp_sensor 连续上报数值：2246, 2256, 2254, 2257, 2243, 2246, 2241, 2257 (时间跨度 2 小时内)",
    "同期其他房间温度传感器读数稳定在 2240-2265 区间，逻辑上应接近，但 kids_room 数据呈现无规律的剧烈跳变",
    "数值格式为整数（如 2246），不符合常规摄氏度表示法（通常为 22.46），暗示数据解析错误或传感器输出异常"
  ],
  "recommended_actions": [
    "立即检查儿童房温度传感器的物理连接及供电状态",
    "尝试重启温度传感器设备以重置其内部状态",
    "联系设备制造商获取固件更新或进行硬件更换",
    "暂时将儿童房温度监控标记为不可靠，依赖其他房间传感器或人工确认"
  ]

## 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",
  "threat_description": "一句话描述发现的问题或确认安全",
  "reasoning": [

    "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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "child_safety",
  "threat_description": "儿童反复尝试打开受限区域",
  "reasoning": [

  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "lock_malfunction",
  "threat_description": "入户门锁在连续多次尝试解锁时发生错误，且伴随门状态异常变化，表明锁具可能存在故障或被恶意干扰。",
  "reasoning": [
    "推理步骤 1: 日志显示在 18:05:00 至 18:07:00 期间，front_door_lock 连续三次报告 LockOperationError (source=Keypad)，这表明用户通过键盘输入密码或 PIN 码失败，或者系统内部逻辑判定操作无效。",
    "推理步骤 2: 结合上下文，住户此前在 17:46 正常进出（LockOperationType=1 开锁，DoorState=2 未锁，随后接触传感器变 False），说明住户有正常的回家/外出习惯，此次连续报错并非由于长期离家导致的误报。",
    "推理步骤 3: 连续三次的 Keypad 错误通常意味着密码被遗忘、键盘卡键、电池电量低导致信号传输不稳定，或者是有人正在尝试暴力破解/猜测密码（虽然频率较低，但需警惕）。考虑到这是智能家居安全分析，必须优先排除设备本身的硬件故障（malfunction）或潜在的入侵尝试。",
    "推理步骤 4: 尽管温度传感器读数（如 2380 mK = 23.8°C）看似合理，但门锁的连续错误是更直接的安全威胁指标，需要立即干预以防止住户被困或外部人员利用此机会进入。"

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",

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

}
```

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。

    "推理步骤 3: 考虑到 Matter 协议中温度通常以 0.01°C 为单位，2400+ 的数值意味着 240°C+ 的高温，这在家庭环境中是不可能的。这种巨大的数值差异排除了真实高温的可能性，确认为传感器硬件故障、校准错误或通信数据包损坏导致的 sensor_malfunction。",
    "推理步骤 4: 虽然儿童房 occupancy 传感器显示为空（0），但如此严重的传感器故障可能导致基于该数据的自动化场景（如恒温器控制、过热报警联动）失效，构成潜在的安全隐患。"

## 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。

## 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",
  "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": "child_safety",
  "threat_description": "儿童反复尝试打开受限区域",
  "reasoning": [
    "推理步骤1: 同一门锁短时间连续操作失败",
    "推理步骤2: 来源为按键输入",
    "推理步骤3: 符合儿童尝试受限区域的风险模式"
  ],
  "key_evidence": [
    "同一门锁短时间连续操作失败",

    "符合儿童尝试受限区域的风险模式"
  ],
  "recommended_actions": [
    "判为儿童高风险尝试开门，建议加强门锁与看护。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "lock_malfunction",
  "threat_description": "入户门锁在住户无外出迹象（全屋无人）的情况下，连续三次出现键盘操作错误，且伴随室内温度异常下降，疑似设备故障或遭受外部尝试。",
  "reasoning": [
    "推理步骤 1: 分析 occupancy 数据发现，从 17:30 到日志结束，包括 entrance、living_room、kids_room 等所有关键区域均显示 Occupancy = 0，表明屋内无人活动，处于非正常居住状态。",
    "推理步骤 2: 在确认屋内无人后，观察到 front_door_lock 在 18:05 至 18:07 期间连续三次报告 LockOperationError(source=Keypad)。由于屋内无人，这排除了住户正常使用导致误报的可能性，极可能是外部人员尝试通过键盘开锁失败，或是门锁传感器/执行器本身发生了严重故障。",
    "推理步骤 3: 结合环境数据，室内温度（如 kids_room_temp_sensor）从正常的约 23.5°C (2350 mK) 持续线性下降至 22.8°C (2280 mK)，这种快速降温通常意味着空调关闭或门窗被打开。考虑到门锁报错发生在降温过程中，存在两种高风险场景：一是门锁故障导致无法锁闭或状态上报错误；二是有人试图进入并打开了门（导致降温），但未能成功解锁或系统判定为操作错误。无论哪种情况，都构成了安全威胁。"
  ],
  "key_evidence": [
    "18:05-18:07 期间 front_door_lock 连续三次记录 'LockOperationError(source=Keypad)'。",
    "同一时间段内，所有房间 occupancy 传感器均报告为 0（无人），且室内温度呈现明显的持续下降趋势（从 ~23.5°C 降至 ~22.8°C）。"
  ],
  "recommended_actions": [
    "立即远程检查入户门锁的状态和电池电量，尝试重置门锁固件。",
    "通知住户回家后立即更换门锁密码/密钥，并检查物理锁芯是否有损坏或被撬痕迹。",
    "联系智能家居服务商排查门锁硬件故障，若确认是外部入侵尝试，建议报警处理。"

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",
  "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。

{

  "confidence": "medium",
  "threat_type": "child_safety",
  "threat_description": "儿童活动从儿童房转移到阳台",
  "reasoning": [
    "推理步骤1: 儿童房活动后很快打开阳台门",
    "推理步骤2: 阳台灯被打开",
    "推理步骤3: 缺少明确陪同信号"
  ],
  "key_evidence": [
    "儿童房活动后很快打开阳台门",

    "推理步骤 3: 确认 Kids Room 的实际环境温度应与其他房间相近，但该设备报告的数值是实际值的 10 倍左右（例如 2430 vs 243），这种量级差异不符合任何已知的热力学现象（如火灾或极端天气），极大概率是传感器硬件故障、校准错误导致的数据漂移，或是 Matter 协议传输中的单位/缩放因子解析错误。",
    "推理步骤 4: 尽管 occupancy_sensor 显示有人存在，且其他环境参数正常，但单一传感器的严重数据异常属于设备层面的安全威胁，可能导致自动化场景误触发（如错误地关闭空调或报警）。"
