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": 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: 正常样本是晚餐时间且有成人活动；异常样本发生在夜间儿童应睡时段。"
  ],
  "key_evidence": [
    "正常样本是晚餐时间且有成人活动；异常样本发生在夜间儿童应睡时段。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "儿童房温度传感器报告了异常高的数值（2342-2349），远超正常物理温度范围，且伴随频繁的数据跳变，表明传感器可能故障或受到干扰。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，在 2026-08-06T17:20:00 至 18:15:00 期间，kids_room_temp_sensor 连续多次上报温度值分别为 2342, 2349, 2347, 2326, 2317 等。",
    "推理步骤 2: 这些数值的单位如果是摄氏度 (°C)，则意味着房间温度超过 2300 度，这在家庭环境中是不可能的；即使单位是毫开尔文 (mK) 或其他内部编码，该数值也远高于 Matter 协议中温度传感器的典型量程（通常为 -40°C 到 +125°C）。",
    "推理步骤 3: 结合同一时间段内 occupancy_sensor 持续报告有人 (Occupancy=1)，说明设备处于工作状态而非离线。如此极端的读数与随后恢复正常范围 (2300 以下) 的读数形成鲜明对比，排除了环境突变的可能性，确认为传感器硬件故障、校准错误或数据上报错误。",
    "推理步骤 4: 虽然儿童房温度异常可能引发过热担忧，但鉴于数值的荒谬性，首要风险是传感器本身失效导致误报或无法监测真实高温，属于 sensor_malfunction。"
  ],
  "key_evidence": [
    "2026-08-06T17:20:00 | kids_room_temp_sensor | TemperatureMeasurement.MeasuredValue = 2342",

    "2026-08-06T18:15:00 | kids_room_temp_sensor | TemperatureMeasurement.MeasuredValue = 2308 (数值回落)"
  ],
  "recommended_actions": [
    "立即检查儿童房温度传感器的物理状态，确认是否被遮挡、损坏或电池电量不足。",
    "尝试重置该温度传感器，并重新校准其读数。",
    "在修复前，建议家长人工定期手动测量儿童房实际温度，以防传感器完全失效导致真实高温未被发现。",
    "联系设备制造商或技术支持以获取固件更新或更换新传感器。"

## 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。

```json

    "1. 烹饪活动分析：厨房灶具（kitchen_cook_surface）在三个时间段开启（06:39-07:29, 18:11-?, 19:01-?），且每次开启后不久灯光关闭或伴随其他正常活动。特别是傍晚时段（18:11和19:01）的连续开启符合晚餐准备的习惯。虽然日志中未明确记录灶具关闭时间（最后一条是19:01开启），但结合18:11后的温度数据波动及后续无烟雾报警，推测为正常烹饪过程，未检测到无人看管导致的火灾风险。",
    "2. 人员活动模式：主卧 occupancy 传感器全天大部分时间为占用状态（Occupancy=1），仅在凌晨00:00为0，符合住户作息。儿童房 occupancy 在17:23至18:43期间有间歇性触发，可能是孩子在房间内活动或传感器误报/灵敏度问题，但未发现长时间静止不动（跌倒风险）或完全无活动的异常情况。入口和客厅的运动传感器在傍晚时段频繁触发，符合家庭成员回家后的活动轨迹。",
    "3. 环境数据一致性：各房间温度传感器读数在合理范围内（约22.9°C - 23.5°C），数值变化平缓，无剧烈跳变表明传感器工作正常。没有漏水传感器、烟雾报警器或一氧化碳报警器的触发记录。",
    "4. 综合判断：所有事件均落在正常的生活节奏内，没有非法入侵迹象（门锁无异常操作记录，运动传感器与预期活动一致），也没有设备故障或危险状态的证据。"
  ],
  "key_evidence": [
    "kitchen_cook_surface 在 06:39, 18:11, 19:01 多次开启，配合 kitchen_light 开关，呈现典型的早餐和晚餐烹饪模式。",

    "全时段无 smoke_co_alarm, water_leak_detector 报警，且温度数据稳定，排除火灾和水患风险。",
    "entrance_occupancy 和 living_room_occupancy 在 18:12 左右同时触发，符合家庭成员归家场景。"
  ],
  "recommended_actions": [

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",

  ],
  "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。

## 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: ...",

    "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: 正常样本是一两次失败后由成人成功开门；异常样本是短时连续失败尝试。"
  ],
  "key_evidence": [
    "正常样本是一两次失败后由成人成功开门；异常样本是短时连续失败尝试。"
  ],
  "recommended_actions": [

  ]
}

```json
{

  "threat_type": "lock_malfunction",
  "threat_description": "入户门锁在尝试通过键盘解锁时发生错误，随后门状态变为开启，且存在未授权进入或内部人员误操作导致的安全隐患。",
  "reasoning": [
    "推理步骤 1: 在 2026-08-28T18:05:00 记录到 front_door_lock 报告了 LockOperationError(source=Keypad)，表明门锁的认证机制（可能是密码或数字键盘）未能成功执行锁定/解锁操作。",
    "推理步骤 2: 紧接着在 2026-08-28T18:06:00，门锁状态变为 2 (通常代表 Unlock/Open)。结合前一步的错误日志，这极有可能是因为认证失败后系统自动回退到某种默认状态，或者是有人在内侧手动开门但未重新上锁，亦或是攻击者利用故障窗口期进入了室内。",
    "推理步骤 3: 虽然之后 entrance_occupancy 持续显示为 1 (有人)，但这无法排除外部入侵的可能性。门锁的关键安全功能（通过凭证验证并执行锁定）出现了明显故障，属于高风险事件，需要立即核实物理状态。"
  ],
  "key_evidence": [

    "[2026-08-28T18:06:00] front_door_lock | DoorLock.LockState = 2"
  ],
  "recommended_actions": [
    "立即前往入户门口检查门锁的物理状态，确认是否被非法闯入或处于未锁定状态。",
    "检查门锁固件版本，查看是否有已知的 Keypad 模块漏洞，并考虑重置门锁设置或更换电池。",
    "如果确认有入侵迹象，应立即报警并联系物业/安保公司进行专业检修。"

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",

    "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",

  "reasoning": [
    "1.  occupancy传感器（运动检测）在大部分时间段（00:00-16:00）均报告为0（无人），符合白天家庭成员外出或处于其他房间/睡眠状态的正常行为模式。仅在16:10和16:13短暂检测到儿童房和客厅有人，随后又恢复无人状态，这可能是短暂的经过或活动，且时间较短，不构成异常滞留。",
    "2.  温度传感器读数（如2466, 2450等）虽然数值较高，但这是Matter协议中TemperatureMeasurement集群的标准格式，单位为0.01摄氏度（即24.66°C, 24.50°C）。这些温度值在合理的生活环境温度范围内，且随时间有正常的波动（如空调运行或自然温差），没有显示出设备故障或极端环境风险。",
    "3.  阳台门传感器在16:12报告状态为False（通常代表关闭/锁定，具体取决于配置，但结合上下文无入侵迹象），且此时客厅和儿童房均有人员活动记录，可能是家庭成员进出阳台区域，属于正常生活场景。",
    "4.  所有关键安全设备（烟雾报警器、漏水传感器、门锁）在提供的日志片段中未触发任何告警或异常状态变化。"
  ],
  "key_evidence": [
    "OccupancySensing.Occupancy = 0 在大部分时间段持续存在，表明无非法入侵或长时间无人看管的风险。",

    "无烟雾、漏水、门锁异常等安全类事件发生。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续监控日常日志以建立更精确的行为基线，但目前数据完全正常。"
  ]
}
```

  "threat_type": "sensor_malfunction",
  "threat_description": "儿童房温度传感器读数异常（约 2400-2460），远超正常物理温度范围，且与其他房间传感器数据不匹配，表明设备故障或校准错误。",
  "reasoning": [
    "推理步骤 1: 分析日志发现 kids_room_temp_sensor 在 14:10 至 17:05 期间持续报告数值在 2350 到 2466 之间。",
    "推理步骤 2: 对比同一时间段内其他房间（如 living_room, master_bedroom, kitchen）的温度传感器数据，其读数均在 2350-2430 的合理范围内（代表约 23.5°C - 24.3°C）。",
    "推理步骤 3: 考虑到 Matter 协议中温度通常以 0.01°C 为单位，2400+ 的读数意味着显示为 240°C+，这在家庭环境中是不可能的。这种巨大的偏差且与其他正常工作的传感器形成鲜明对比，确认为传感器硬件故障、固件 bug 或通信数据包解析错误，而非真实的环境异常。"

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
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": 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: 正常样本是一两次失败后由成人成功开门；异常样本是短时连续失败尝试。"
  ],
  "key_evidence": [
    "正常样本是一两次失败后由成人成功开门；异常样本是短时连续失败尝试。"
  ],
  "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": [
    "正常样本是一两次失败后由成人成功开门；异常样本是短时连续失败尝试。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]
}
