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 2 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
{
  "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": 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: 正常样本做饭持续 20 分钟左右；异常样本连续两天都只持续约 5 分钟。"
  ],
  "key_evidence": [
    "正常样本做饭持续 20 分钟左右；异常样本连续两天都只持续约 5 分钟。"
  ],
  "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": [
    "正常样本做饭持续 20 分钟左右；异常样本连续两天都只持续约 5 分钟。"
  ],

## 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。",

  "threat_description": "独居老人在凌晨时段出现长时间无活动且室内温度异常升高，存在健康风险或意外滞留的可能性。",
  "reasoning": [
    "推理步骤 1: 时间窗口分析显示，从 02:18 到 05:30（约 3.5 小时），卧室灯被打开，但随后直到 09:36 之前，所有房间（包括客厅、厨房、卫生间）的运动传感器均持续报告无人状态（Occupancy=0）。对于独居老人而言，深夜起床开灯后长时间未返回卧室或离开房间是极不寻常的行为模式。",
    "推理步骤 2: 环境数据异常，在此期间客厅和厨房的温度传感器读数持续攀升并超出正常舒适范围（例如 04:00 时客厅温度达到 2402 mK 即 24.02°C，05:30 时厨房达到 2376 mK 即 23.76°C，且趋势仍在上升）。在夜间无人活动的情况下，空调系统未能有效调节温度或设备故障导致过热，增加了安全隐患。",
    "推理步骤 3: 结合住户画像（独居老人），这种“夜间活动 - 长时间静止 - 高温环境”的组合高度疑似老人突发身体不适（如中风、跌倒昏迷）导致无法移动，或者因睡眠障碍/认知问题在夜间游荡后迷失方向。虽然 05:59 有短暂的卫生间占用记录，但这可能是家人短暂进入查看，不能排除老人仍处于危险状态的风险。"
  ],
  "key_evidence": [
    "02:18 至 05:30 期间，除一次短暂的卫生间占用外，全屋运动传感器连续 3.5 小时报告无人状态。",
    "同一时间段内，客厅和厨房温度持续异常升高，最高达 24.02°C，且未见降温迹象。",
    "住户为独居老人，缺乏即时监护，长时间无活动属于高危信号。"
  ],
  "recommended_actions": [
    "立即通过智能家居语音助手或电话尝试联系老人，确认其安全状况。",
    "若联系不上，建议家属或紧急联系人尽快上门查看，或联系社区/急救服务进行核查。",
    "检查空调及温控系统是否正常工作，防止因设备故障导致的极端温度对老人造成二次伤害。"

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
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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常情况，设备日志显示独居老人的日常活动模式稳定且符合预期。",
  "reasoning": [
    "1. 活动模式一致性分析：对比2026-08-16至08-18的跨天摘要数据，各房间的活动计数（如living_room约210+，kitchen约237+）保持高度一致，表明住户的生活作息规律，无突发的行为改变或长期静止（abnormal_inactivity）。",
    "2. 关键区域活动逻辑验证：厨房（kitchen_occupancy）和客厅（living_room_occupancy）在早晨7:00-10:00期间频繁触发占用信号，符合老人起床、准备早餐及晨间活动的正常行为特征。没有发现深夜异常活动或长时间无人却有人感应的矛盾情况。",
    "3. 环境与安全状态检查：日志中未出现烟雾报警器（smoke_co_alarm）、漏水传感器（water_leak_detector）或门窗传感器（contact_sensor）的报警/异常开启记录。温度读数在合理范围内波动（24°C-25°C左右），无极端值暗示设备故障或火灾风险。",
    "4. 门锁与入口安全：入户门传感器仅在早晨短暂触发（如08:27, 08:52等），随后恢复常态，未见非法入侵迹象或门锁故障报错。"
  ],
  "key_evidence": [
    "连续三天各房间活动计数高度稳定（例如Kitchen: 237, 239, 238），证明生活规律正常。",
    "早晨时段（07:00-10:00）厨房和客厅占用传感器活跃，符合独居老人晨间活动习惯。",
    "所有安全类传感器（烟雾、漏水、门窗）在日志片段中均无异常触发记录。"
  ],
  "recommended_actions": [
    "继续保持当前的监控策略，无需干预。",
    "建议定期校准温度传感器以确保读数准确性，尽管当前数据看起来正常。"
  ]
}
```

{
  "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": [
    "正常样本仍保持多房间活动；异常样本逐渐收缩到卧室附近。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"

## 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: ...",
    "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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常情况，设备日志显示住户活动规律，环境参数正常。",
  "reasoning": [
    "1. **厨房灶具状态分析**：虽然重点关注的 kitchen_light 在三天内多次开启（06:07, 12:05, 12:35, 12:15），且伴随厨房运动传感器激活，但唯一出现的 cook_surface 事件发生在 2026-07-12T11:27:00，状态为 'Off'。日志中未记录任何 'On' 状态或持续高温/烟雾报警，表明没有发生无人看管烹饪或火灾风险。",
    "2. **住户活动模式一致性**：跨天摘要显示各房间活动量稳定（如 living_room 约 210-211，bedroom 约 240-242）。具体日志中，早晨 06:00-06:10 有灯光和可能的起床活动，中午 11:30-13:00 期间多个房间（客厅、卧室、厨房、玄关）均有运动传感器触发，符合独居老人日间正常起居、用餐和活动的节奏，无长时间静止导致的跌倒或健康异常迹象。",
    "3. **环境与传感器数据正常**：温度读数在合理范围内波动（客厅约 24-25°C，卧室略低），未见极端值或传感器漂移。门窗传感器仅在特定时间（如 11:38, 12:03 等）短暂触发后恢复，结合运动传感器同时激活，判断为正常的开门出入或通风行为，非入侵迹象。"
  ],
  "key_evidence": [
    "cook_surface 仅出现 Off 状态，无 On 状态记录，排除 unattended_cooking 风险。",
    "多日跨天活动摘要数值稳定，证明住户生活规律，无 abnormal_inactivity。",
    "厨房灯与运动传感器联动频繁，符合日常做饭/活动习惯，非异常入侵。"
  ],
  "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数据准确性。"
  ]
}
```

{
  "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": [
    "正常样本午餐时间有小幅波动；异常样本跨天明显后移。"

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": 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: 正常样本是短时起夜；异常样本在厨房等非卧室区域停留过久。"
  ],
  "key_evidence": [
    "正常样本是短时起夜；异常样本在厨房等非卧室区域停留过久。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "health_concern",
  "threat_description": "独居老人在凌晨时段出现长时间无活动且室内温度异常升高，存在严重的健康风险或意外滞留风险。",
  "reasoning": [
    "推理步骤 1: 时间分析显示，从 02:18 到 05:38（约 3.5 小时），卧室灯被打开，但随后直到 05:38 之前没有任何运动传感器报告检测到人员活动（所有房间 occupancy 均为 0）。对于独居老人而言，深夜起床开灯后长时间未移动是极不正常的行为模式。",
    "推理步骤 2: 环境数据表明，在疑似无人活动的同时，客厅和厨房的温度持续异常攀升。例如，客厅温度从 00:00 的 22.8°C (2280mK) 上升至 04:10 的 24.1°C (2411mK)，且在此期间没有空调调节记录（日志中未见 air_conditioner 状态变化），这暗示可能有人体热源导致升温，或者空调系统故障/关闭，加剧了高温风险。",
    "推理步骤 3: 结合住户画像（独居老人）和行为逻辑，最合理的推断是老人可能在 02:18 左右起身（可能是如厕或饮水），但在返回床上前发生了跌倒、晕厥或其他突发健康状况，导致无法移动。由于缺乏后续活动信号，且夜间温度持续上升，必须优先排除生命体征异常或被困风险。"
  ],
  "key_evidence": [
    "02:18 至 05:38 期间，尽管卧室灯开启，但所有房间的运动传感器连续数小时报告 Occupancy = 0。",
    "凌晨时段（02:00-05:00）室内温度呈现非自然的持续上升趋势（客厅从 22.8°C 升至 24.1°C），且无空调制冷动作记录。",
    "住户为独居老人，深夜长时间静止不动属于高危异常行为模式。"
  ],
  "recommended_actions": [
    "立即触发最高级别警报，并通过电话、短信或智能音箱语音唤醒老人确认安全状况。",
    "若联系不上或老人未回应，立即通知紧急联系人及当地急救/安保部门进行上门核查。",
    "检查并重置空调系统，防止因设备故障导致的室内过热风险。"
