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
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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。

  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "检测到厨房温度持续异常升高，且伴随人员活动，存在严重的火灾风险。",
  "reasoning": [
    "推理步骤 1: 分析温度数据趋势。从 00:00 到 07:00，厨房温度传感器读数从 2275 (约 22.75°C) 持续线性上升至 2518 (约 25.18°C)。随后在 07:06 至 09:40 期间，温度进一步攀升至峰值 2555 (约 25.55°C)，并在后续时段维持在 2540-2557 的高位区间。这种持续数小时的升温模式远超正常环境温度波动范围。",
    "推理步骤 2: 结合住户画像与场景。住户为独居老人，通常对高温反应较慢或行动不便。厨房是烹饪区域，如此高的温度极可能意味着灶具（cook_surface）处于开启状态但未关闭，或者发生了燃气泄漏导致的燃烧/过热，而无人及时干预。",
    "推理步骤 3: 关联 occupancy 数据验证。日志显示在温度飙升期间（特别是 07:00 之后），entrance_occupancy、kitchen_occupancy 和 bedroom_occupancy 多次报告为 1，表明屋内有人活动。然而，尽管有人在场，温度却未下降反而继续上升，这强烈暗示了‘无人看管烹饪’（unattended cooking）或设备故障导致的热失控，而非单纯的环境升温。考虑到温度已达到危险阈值，升级为火灾风险（fire_risk）。"
  ],
  "key_evidence": [
    "厨房温度在 7 小时内从 ~22.75°C 持续上升至 ~25.55°C，增幅显著且无回落迹象。",
    "在温度达到最高值时，厨房及玄关运动传感器均检测到人员存在（Occupancy=1），但温度未降反升，排除自然散热可能。",
    "该温度水平对于普通室内环境而言过高，符合电器过热或明火燃烧的特征。"
  ],
  "recommended_actions": [
    "立即通过智能家居系统远程切断厨房电源或关闭灶具（如果协议支持）。",
    "向住户发送紧急警报通知其检查厨房情况。",
    "若无法远程干预或确认有烟雾/火情，立即拨打当地紧急服务电话（如 119/911）。",
    "检查厨房烟雾报警器是否正常工作并触发报警。"
  ]
}

## 任务
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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": "actuator_stuck",
  "threat_description": "灯的 OnOff 与 Level 矛盾",
  "reasoning": [
    "推理步骤1: 同一时刻 OnOff=False 但亮度非零",
    "推理步骤2: 矛盾状态持续而非瞬时",
    "推理步骤3: 更像执行/上报故障"
  ],
  "key_evidence": [
    "同一时刻 OnOff=False 但亮度非零",
    "矛盾状态持续而非瞬时",
    "更像执行/上报故障"
  ],
  "recommended_actions": [
    "判断为灯具状态机异常，建议检查执行器或状态同步。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "目标设备 living_room_light_1 状态正常，无异常行为或安全威胁。",
  "reasoning": [
    "推理步骤 1: 检查目标设备 living_room_light_1 的状态变化日志。在 20:10:00 和 20:12:00 记录了两次 OnOff.OnOff = False 事件，随后在 20:10:00 记录了 LevelControl.CurrentLevel = 180（约 60% 亮度）。这表明灯具处于‘关闭但可调节’或‘待机调光’的特定模式，或者是用户手动操作了开关并调整了亮度设置，属于正常的用户交互行为，而非设备故障导致的随机跳变。",
    "推理步骤 2: 结合上下文环境分析。日志显示从 17:17 开始，主卧、玄关、餐厅、儿童房等多个区域的人员占用传感器 (Occupancy) 频繁变为 1，且厨房灶具曾开启后关闭，洗碗机在 19:26 开启。这符合家庭晚间归家、准备晚餐及日常活动的典型时间线。",
    "推理步骤 3: 验证关联设备状态。客厅温度传感器读数稳定下降（从 24.6°C 降至 22.4°C），空调系统模式在 18:18 切换为制冷/自动模式（SystemMode=3），与气温变化和人员活动逻辑一致。未发现门窗非法开启、烟雾报警、漏水或其他异常传感器漂移现象。"
  ],
  "key_evidence": [
    "living_room_light_1 在 20:10:00 出现明确的 OnOff=False 和 LevelControl=180 指令，符合人工操作特征。",
    "全时段内所有运动传感器、门窗传感器及环境传感器（温度、湿度）的数据流连续且逻辑自洽，无冲突或停滞。",
    "厨房设备（灶具、洗碗机）的操作时间与人员进入厨房的时间点吻合，排除了无人看管烹饪的风险。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，当前系统运行正常。",
    "建议继续监控后续日志，确保夜间睡眠模式下各房间照明自动关闭逻辑生效。"
  ]
}

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
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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。

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
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

请按以下 JSON 格式回答：

  "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。

    "3. 验证持续性：紧接着在[2026-08-26T17:30:00]，该传感器读数恢复至22.48°C，并继续随环境正常下降。这种‘尖峰’式的瞬时跳变不符合物理热惯性规律（空气温度不会在几分钟内无外部热源介入下剧烈波动后立刻回落）。",
    "4. 排除其他威胁：虽然17:00有门锁手动开启记录，但随后 occupant 出现在客厅而非卧室，且无其他火灾迹象（如烟雾报警器未触发、厨房灶具未在17:00开启），因此排除真实的高温事件或入侵引发的局部加热。"

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。

    "1. 检测到致命错误数据：在 2026-07-04T14:05:00，bedroom_temp_sensor 上报 TemperatureMeasurement.MeasuredValue = -500。根据 Matter 协议标准，TemperatureMeasurement 的值为整数厘度（centi-degrees Celsius），-500 代表 -5.0°C。对于夏季（7月）的室内环境，这是极不可能的数值，通常表示传感器内部溢出、通信错误或硬件损坏。",
    "2. 观察到异常的数据漂移/缺失：在 14:05 报错后，14:10 恢复为 2440 (24.4°C)，但随后从 14:35 到 18:35，温度读数从 23.5°C 持续、单调地下降到 22.08°C。虽然室内温度会随时间变化，但在有人居住（Bedroom Occupancy 频繁为 1）且客厅空调开启（Living Room AC On）的情况下，卧室温度不应呈现如此平滑且缺乏波动的线性下降，这符合传感器电池电量低导致采样率异常或ADC转换错误的特征。",
    "3. 排除环境因素：同一时间段内，客厅温度传感器（living_room_temp_sensor）显示正常波动（23.04°C - 25.57°C），厨房传感器也显示正常范围。这表明全屋环境温度并未发生剧烈变化，问题局限于卧室传感器本身。"

## 任务
请结合下面的 Matter 设备日志，判断是否存在设备健康问题，并说明可能的故障类型。

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。

{

  "confidence": "medium",
  "threat_type": "sensor_malfunction",
  "threat_description": "洗衣机运行但倒计时不减少",

  ],

    "温度传感器数据解析：日志中的温度值（如 2510）符合 Matter 协议中 TemperatureMeasurement 属性通常以 0.01°C 为单位的存储格式，换算后约为 25.10°C，处于夏季室内正常舒适范围，无过热或漂移现象。",
    " occupancy 模式分析：入户门（entrance）和玄关运动传感器在早晨时段频繁检测到有人（Occupancy=1），随后客厅、餐厅、儿童房等区域陆续有人活动，符合家庭早晨起床、洗漱、准备出门的正常作息规律。",
    "设备状态验证：阳台洗衣机（balcony_laundry_washer）在 10:00 启动，并在后续时间点报告倒计时（CountdownTime=2400，即 40 分钟），状态逻辑连贯，无卡死或异常报错；前门接触传感器在 07:41 变为 True（开门），随后人员进入玄关，行为逻辑一致。",
