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",

    "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。

  "threat_description": "厨房温度传感器在 2026-07-17 出现严重数据漂移和逻辑矛盾，显示异常高温（>260°C）而同一时间客厅温度正常，且伴随设备状态丢失，极可能是传感器故障或受干扰。",
  "reasoning": [
    "推理步骤 1: 对比 2026-07-17 18:00-18:55 期间的数据，厨房温度传感器 (kitchen_temp_sensor) 读数从正常的 ~2386 mK (~24°C) 突然飙升至 2692 mK (~269°C)，并在短时间内剧烈波动至 2708 mK，随后又跳变回 2627 mK。这种物理上不可能的高温（远超烤箱极限）表明传感器读数错误。",
    "推理步骤 2: 在同一时间段内，客厅、主卧、次卧的温度传感器读数均在 2293 mK - 2350 mK 之间（约 23-24°C），变化平缓且符合夜间/傍晚降温规律。这证明环境温度本身是正常的，排除了全屋火灾或极端天气导致的环境升温可能性。",

    "推理步骤 4: 虽然用户操作了厨房灯和空调，但无法解释为何仅厨房传感器失效而其他区域正常。若为烹饪导致的升温，温度应缓慢上升且不会超过 270°C，也不会出现数据中断。因此判定为传感器故障 (sensor_malfunction/sensor_drift)。"

    "同期其他房间（客厅、卧室）温度传感器读数稳定在 2293-2350 mK (约 23-24°C)，证实环境整体温度正常。",

## 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。

    "2. 厨房安全无异常：18:25 灶具关闭，随后洗碗机启动（18:25:14），这是典型的晚餐后清洁流程。虽然日志中 kitchen_temp_sensor 在18:26出现一次 None 值，但随后立即恢复正常读数且温度呈自然下降趋势（从2309降至2244等），排除传感器故障或火灾风险。",
    "3. 卧室无人确认：主卧和次卧的 occupancy_sensor 在晚间时段持续报告为 0，且温度随时间缓慢下降（如主卧从2310降至2242），符合无人居住时的自然散热规律，未发现异常入侵或长时间静止的健康风险。",
    "4. 卫生间活动正常：卫生间 occupancy_sensor 在多个时间点（18:32, 19:02, 19:32, 20:32, 21:02, 21:32, 22:02）均报告为 0，表明卫生间未被占用，无跌倒或被困迹象。"

    "master_bedroom_occupancy 和 second_bedroom_occupancy 在 18:00-22:00 期间持续为 0，且对应房间温度自然下降。",
    "bathroom_occupancy 在整段日志期间始终为 0，无异常滞留。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",

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": [

    "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，日志显示为正常的家庭晚间活动模式。",
  "reasoning": [
    "1. 人员活动符合常规作息：日志时间跨度为17:20至22:10，属于典型的傍晚至睡前时段。多个房间（客厅、餐厅、儿童房、主卧）的运动传感器频繁触发（Occupancy=1），且伴随灯光开启（如19:00客厅灯亮）和空调调节，表明家庭成员在正常居家活动。",
    "2. 设备状态逻辑一致：客厅温度从23.5°C逐渐下降至22.4°C左右，同时空调被设置为制冷模式（SystemMode=3），这符合夏季晚间降温的正常行为。厨房窗户关闭（Contact=False）与室内温度稳定相符，无异常开启迹象。",
    "3. 无入侵或异常特征：入户门传感器仅在玄关运动传感器触发时偶有联动记录（可能是误报或家人进出），但未出现门锁异常解锁、非法闯入或深夜无人时的异常活动。所有事件均在合理的时间窗口内发生，没有长时间静止后的突然活跃等可疑模式。"
  ],
  "key_evidence": [
    "18:06-22:10期间，living_room_occupancy, kids_room_occupancy, master_bedroom_occupancy等多处传感器持续报告有人存在（Value=1）。",
    "18:06 living_room_ac Thermostat.SystemMode = 3 (制冷)，配合温度从23.51降至22.46，符合主动降温行为。",
    "19:00 living_room_light_1 OnOff=True，随后21:30 Off，符合晚间照明使用习惯。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续监控夜间（23:00后）的异常活动，确保睡眠期间无未授权进入。"
  ]
}
```

{
  "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": [
    "正常样本只是晚间一次开关灯；异常样本短时间内重复高频操作。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"

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

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: 结合住户画像（独居老人），这种温度的急剧变化通常意味着有人离开了空调/暖气覆盖区域，或者该区域无人居住但门窗被打开。然而，日志显示在此期间卧室运动传感器（bedroom_occupancy）在 17:58 和 18:43 仍有两次'1'的读数，表明有人进入过，但之后直到 19:35 再无活动记录。",
    "推理步骤 3: 考虑到老人独居，如果在 18:43 最后一次检测到活动后，老人未能返回卧室中心区域或离开卧室但未触发其他房间的活动，同时卧室温度因无人调节而迅速下降，这强烈暗示老人可能发生了跌倒或其他意外情况，导致其被困在角落或无法移动，从而触发了基于行为模式的健康风险警报。",

## 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。

{
  "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: 正常样本仍有零星厨房活动；异常样本连续多天完全缺失相关使用。"
  ],
  "key_evidence": [
    "正常样本仍有零星厨房活动；异常样本连续多天完全缺失相关使用。"
  ],
  "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": [
    "正常样本仍有零星厨房活动；异常样本连续多天完全缺失相关使用。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]
}


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，日志显示为正常的夜间无人居住状态及偶发的灯光操作。",
  "reasoning": [
    "1. **人员活动分析**：从17:00到20:30，所有房间（客厅、主卧、次卧、卫生间、玄关）的运动传感器（Occupancy Sensor）持续报告值为0，表明房屋内无人活动。这符合傍晚至夜间家庭成员休息或外出的正常行为模式。",
    "2. **环境数据一致性**：温度传感器读数在22.6°C - 23.5°C之间波动（Matter协议中通常以0.01摄氏度为单位，即2355代表23.55°C），数值变化平缓且符合室内环境温度特征，无剧烈跳变，排除传感器故障或极端天气入侵风险。",
    "3. **设备状态逻辑**：仅在19:00有一次客厅主灯开启（OnOff=True），并在14分钟后于21:30关闭。虽然中间有长时间间隔，但考虑到全屋无人的背景，这可能是自动化场景触发（如定时开关）、误触或用户短暂进入后离开。由于没有伴随其他异常（如门锁开启、烟雾报警、漏水等），且最终状态回归平静，不构成即时威胁。",
    "4. **综合判断**：缺乏入侵迹象（门锁未异常开启、窗户未打开）、缺乏火灾/燃气风险（无烟雾/CO报警）、缺乏健康风险（无跌倒检测或长时间静止警报）。整体表现为安全的静态监控状态。"
  ],
  "key_evidence": [
    "所有区域运动传感器在17:00-20:30期间持续返回 Occupancy = 0",
    "温度读数稳定在舒适区间 (22.6-23.5°C)，无异常波动",
    "仅发生一次短暂的客厅灯光开启事件，随后系统恢复无人静止状态"
  ],
  "recommended_actions": [
    "无需立即干预，保持当前监控策略即可。",
    "若该灯光开启行为非用户预期，可检查是否配置了错误的自动化规则或存在智能音箱/语音助手的误唤醒情况。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
