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: ...",

    "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": "出门频率突然下降",
  "reasoning": [
    "推理步骤1: 首日仍有出门链路",
    "推理步骤2: 后续明显缺少外出相关事件",
    "推理步骤3: 可能反映社交/功能退缩"
  ],
  "key_evidence": [

    "后续明显缺少外出相关事件",
    "可能反映社交/功能退缩"
  ],
  "recommended_actions": [
    "标记为出门频率异常下降，建议结合老人状态持续观察。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示独居老人的日常活动模式正常，无入侵、设备故障或环境安全隐患。",
  "reasoning": [
    "入住与出门时间规律：前门接触传感器（front_door_contact）在每天早晨约 07:00-09:00 之间检测到开门进入，晚上约 20:43-20:51 检测到关门离开，且连续三天时间窗口高度一致，符合独居老人的正常作息习惯。",
    "室内活动逻辑自洽：卧室占用传感器（bedroom_occupancy）在老人起床后不久（约 07:27-08:00）变为有人状态，随后客厅和厨房频繁出现人员活动，表明老人已开始在屋内活动，不存在长时间无人导致的异常静默。",
    "设备状态健康：门锁操作记录（LockOperation）显示为手动上锁，状态正常；温度传感器读数稳定在合理范围（约 24.4°C - 25.6°C），未出现漂移或故障跳变；未见漏水、烟雾报警等安全设备触发事件。"
  ],
  "key_evidence": [
    "2026-08-12T09:00:00 front_door_contact StateValue=False (出门) 与 2026-08-12T20:43:14 front_door_contact StateValue=True (回家) 的时间间隔符合夜间休息时长。",
    "2026-08-12T07:27:00 bedroom_occupancy=1 紧随 07:20:00 的起床迹象，且后续 kitchen/living_room 均有高频活动记录，证明是住户本人活动而非外人闯入。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",
    "建议定期检查老人身体健康状况，确保其日常生活自理能力稳定。"
  ]

## 任务
请从下面 2 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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "health_concern",
  "threat_description": "做饭时间异常短",
  "reasoning": [

    "推理步骤3: 可能提示进食不足或功能下降"
  ],

  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器在烹饪活动期间出现数据丢失（None），且读数与客厅及卧室传感器相比存在异常漂移，可能导致火灾风险未被及时监测。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，2026-08-17 和 2026-08-18 期间，住户多次在厨房开启灶具（kitchen_cook_surface OnOff=True）进行烹饪活动，此时厨房运动传感器显示有人（Occupancy=1）。",
    "推理步骤 2: 正常情况下，烹饪时厨房温度应显著高于其他房间。然而，日志显示厨房温度传感器（kitchen_temp_sensor）在 2026-08-18T11:33:00 突然报告值为 None（数据丢失），随后在 11:40:00 恢复为 2529，而同一时间段的客厅和卧室温度稳定在 25°C 左右（约 2540-2550 mK），这表明传感器可能发生了通信中断或硬件故障，而非环境突变。",
    "推理步骤 3: 考虑到独居老人这一高风险群体，以及烹饪是主要的火灾诱因，关键的安全传感器（温度/烟雾）失效属于严重安全隐患。虽然烟雾报警器未直接报错，但作为辅助监测的温度传感器失灵会导致系统无法准确判断过热情况，增加了误报或漏报的风险。"
  ],
  "key_evidence": [
    "2026-08-18T11:33:00 kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = None (在烹饪活动中)",

  ],
  "recommended_actions": [
    "立即检查厨房温度传感器的电池、连接状态及固件版本，必要时更换设备。",
    "在修复前，建议人工增加对厨房区域的巡查频率，特别是在烹饪时段。",
    "验证烟雾报警器的功能是否正常，确保其能独立承担火灾探测任务。"

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

  "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
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",

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。

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
{

  "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
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

  "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。
