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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "health_concern",
  "threat_description": "老人连续多天活动范围缩小",
  "reasoning": [

    "推理步骤3: 提示功能退化或健康问题"
  ],

    "跨天持续出现",
    "提示功能退化或健康问题"
  ],
  "recommended_actions": [

  ]
}

```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、火灾或设备故障迹象。",
  "reasoning": [
    "时间线分析：所有事件均发生在合理的起床（07:00-08:30）、早餐/厨房活动（08:30-10:00）和日间活动时段，符合独居老人的典型作息规律。",
    "空间逻辑验证：运动传感器触发顺序合理（入户门 -> 玄关 -> 客厅/厨房），且卧室在夜间（00:00-06:59）保持无人状态，排除了非法入侵或异常滞留的可能性。",
    "环境数据校验：温度传感器读数（约 24.5°C - 25.5°C）处于舒适且安全的范围内，未出现烟雾报警器误报或高温预警；虽然 07-23 厨房传感器曾短暂丢失数据，但随后立即恢复并记录正常数值，属于瞬时通信波动而非持续故障。",
    "行为一致性：老人每日活动轨迹高度一致，未见长时间静止不动（排除跌倒风险）或深夜异常移动等危险信号。"
  ],
  "key_evidence": [
    "连续三天（07-21 至 07-23）的起床时间和厨房活动时间窗高度重合，表明生活规律稳定。",
    "夜间（00:00 至次日 07:00）所有房间 occupancy 均为 0，且无任何非预期开门事件。",
    "温度传感器读数稳定在 24-26 摄氏度区间，无火灾前兆的高温异常。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",
    "建议定期检查厨房漏水传感器和烟雾报警器的电池状态，确保长期可靠性。",
    "鉴于老人独居，可考虑在现有基础上增加每周一次的远程健康问候或视频通话确认。"

## 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",

    "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 2: 结合住户背景（独居老人）和环境常识，室内环境温度绝不可能达到 250°C 以上，即使厨房灶具开启也不可能导致整个客厅瞬间升温至此并维持数小时。这种数值远超 Matter 协议中温度传感器的合理量程（通常为 -40°C 到 +125°C）。",
    "推理步骤 3: 虽然其他房间（如卧室、厨房）的温度传感器读数正常（约 23-24°C），但客厅传感器在同一时间段内持续输出荒谬的高数值，排除了环境真实发生超高温火灾的可能性，确认为传感器硬件故障或通信数据漂移（Sensor Drift/Malfunction）。对于独居老人，错误的温度读数可能导致空调系统误判而失效，引发真实的过热风险。"

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",

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。

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",

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: ...",
    "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": "health_concern",
  "threat_description": "夜间长期停留在非卧室区域",
  "reasoning": [
    "推理步骤1: 深夜在非卧室区域持续活动",
    "推理步骤2: 时长明显超出普通起夜",
    "推理步骤3: 可能是迷路或意识混乱"
  ],
  "key_evidence": [
    "深夜在非卧室区域持续活动",
    "时长明显超出普通起夜",
    "可能是迷路或意识混乱"
  ],
  "recommended_actions": [
    "按老人夜间异常活动处理，建议家属关注。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "检测到厨房区域在无人状态下出现异常高温持续上升，且伴随灯光开启，存在极高的火灾风险。",
  "reasoning": [
    "推理步骤 1: 时间与环境分析。日志显示时间为凌晨 02:10 至 04:20，此时独居老人通常处于睡眠状态（卧室温度稳定在 22°C 左右，而客厅/厨房温度显著升高），所有房间的运动传感器均报告 Occupancy = 0，确认屋内无人。",
    "推理步骤 2: 温度异常模式识别。厨房温度传感器读数从 02:10 的 23.4°C (2340 mK) 开始，呈现持续且快速的上升趋势，至 04:00 达到峰值 24.1°C (2410 mK)，温差超过 0.7°C。这种在无人员活动的情况下，特定房间温度持续攀升的现象不符合正常散热规律，强烈暗示有热源产生。",
    "推理步骤 3: 关联设备行为验证。在温度急剧上升期间（02:50），厨房灯光被意外开启 (OnOff.OnOff = True)。虽然灯光本身发热量不足以导致如此高的温升，但这可能是自动联动或误操作的结果，进一步佐证了该区域存在非正常的电气活动或设备故障（如灶具未关、烤箱过热等）。考虑到是独居老人家庭，夜间无人看管下的热源失控属于最高优先级的火灾隐患。"
  ],
  "key_evidence": [
    "02:10 - 04:00 期间，kitchen_temp_sensor 读数从 2340 持续上升至 2410，且全程 kitchen_occupancy 为 0。",
    "02:50 时 kitchen_light 突然变为 True，发生在温度快速爬升阶段。",
    "同一时间段内，bedroom_temp_sensor 保持稳定 (约 2200-2280)，排除了全屋环境温度普遍升高的可能性。"
  ],
  "recommended_actions": [
    "立即远程通知住户或其紧急联系人，告知可能存在厨房火灾隐患。",
    "若系统具备联动能力，尝试远程关闭厨房电源或触发烟雾报警器测试（需确认安全协议允许）。",
    "建议检查厨房智能插座或灶具设备的固件及状态，排查是否存在过热保护失效或未正确关闭的情况。"

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",

    "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。

    "推理步骤 2: 设备状态异常检测。尽管屋内无人，厨房温度传感器 (kitchen_temp_sensor) 读数从 02:10 的 2330mK (约 23.3°C) 开始持续攀升，在 03:50 达到峰值 2402mK (约 24.0°C)，并在后续时间点维持在极高水平。对于无人操作的厨房，这种持续升温不符合正常散热规律，暗示有热源持续工作。",
    "推理步骤 3: 关联事件验证。在 02:50 出现了 kitchen_light 开启的事件 (OnOff.OnOff = True)。虽然灯光开启本身不产生高温，但结合随后温度的急剧上升和长时间无人看管的状态，高度怀疑灶具 (cook_surface) 或其他加热设备被意外开启或故障，导致在无人的情况下持续加热，构成严重的火灾隐患。"
