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",
    "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。

  "reasoning": [
    "1. 分析卧室温度趋势：从12:20到16:35，卧室温度呈现稳定的下降趋势（从24.15°C降至22.75°C），符合夏季傍晚气温自然回落的规律，且与其他房间（客厅、厨房）的温度变化趋势基本一致。",
    "2. 识别异常点：在17:00:00，卧室温度传感器突然上报值为2920（即29.2°C）。这一数值不仅远高于之前的读数（22.75°C），也显著高于同一时刻的客厅温度（24.40°C）和厨房温度（未直接给出但趋势相近）。",
    "3. 验证恢复情况：仅10分钟后（17:10:00），该传感器读数立即回落到22.49°C，与之前的下降趋势吻合。这种‘瞬间飙升后立刻回归正常’的模式不符合物理环境变化的连续性特征（室内温度不会在10分钟内因自然原因剧烈波动近7度又迅速降回）。",
    "4. 排除其他威胁：虽然独居老人需要关注健康，但该异常表现为单一设备的数值跳变，而非持续的高温环境，因此判定为设备层面的硬件故障或通信/解析错误，而非真实的环境热风险。"

## 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。

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

  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "目标设备 (balcony_laundry_washer) 运行状态正常，无安全威胁或异常行为。",
  "reasoning": [
    "推理步骤 1: 检查洗衣机状态日志。在 2026-07-19T10:00:00 时，阳台洗衣机报告 OperationalState.OperationalState = 1 (运行中)，随后在 10:20、10:40、11:00 多次报告 CountdownTime = 2400 (剩余 40 分钟)。这表明设备正在按计划执行洗涤程序，且倒计时逻辑一致，未出现状态突变或卡死现象。",
    "推理步骤 2: 结合环境上下文分析。日志显示从 08:00 到 13:30 期间，入户门、客厅、餐厅等公共区域及儿童房、主卧的 OccupancySensing.Occupancy 均为 0，表明家中无人。此时启动洗衣机属于典型的离家前或离家后定时/远程操作场景，符合用户习惯，非入侵迹象。",
    "推理步骤 3: 排除其他风险。虽然家中无人，但厨房温度传感器读数稳定（约 25°C），烟雾报警器和漏水传感器未触发警报，灶具和洗碗机无异常活动记录。因此，洗衣机的运行不会引发火灾、漏水或其他次生灾害风险。"

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",
  "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。

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器出现数据丢失（None）及读数异常波动，疑似硬件故障或通信中断。",
  "reasoning": [
    "1. 分析日志时间线：在 2026-08-11T07:11:00，`kitchen_temp_sensor` 上报的 `TemperatureMeasurement.MeasuredValue` 为 `None`，表明该时刻传感器未能提供有效数据或通信链路暂时中断。",
    "2. 观察后续恢复情况：仅在1分钟后（07:15:00），传感器恢复上报数值 2515。然而，对比同一时间段其他房间的温度变化趋势（如主卧从2520降至2521，客厅从2520升至2540等），厨房温度在极短时间内从2495（06:50）跳变至2530（08:10），中间缺失了关键过渡数据。",
    "3. 排除环境因素：虽然早晨可能有开窗或烹饪导致温度变化，但 `None` 值通常代表设备底层读取失败、电池电量耗尽或Zigbee/Matter网络丢包严重。结合其随后数分钟内的数据点与其他传感器相比缺乏平滑过渡，且存在完全无数据的情况，这更符合传感器自身故障（Sensor Malfunction）的特征，而非单纯的环境漂移。"
  ],
  "key_evidence": [
    "[2026-08-11T07:11:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = None",

  ],
  "recommended_actions": [
    "检查厨房温度传感器的电池电量，若电量低请更换电池。",
    "检查厨房区域的Wi-Fi/Zigbee信号强度，确认是否存在网络干扰导致的数据包丢失。",
    "若问题持续，建议重置该传感器或联系厂商进行硬件检测。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_stuck",
  "threat_description": "运动传感器持续报 Occupied",
  "reasoning": [

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。

    "该异常值仅持续了约1小时便恢复正常范围，这种瞬时的、非物理性的数值跳跃是电子传感器硬件故障、通信干扰或固件Bug的典型特征，而非真实的环境温度变化。"

  "recommended_actions": [
    "检查卧室温度传感器的电池电量，低电量可能导致读数不稳定。",
    "尝试重启或重新配对该Matter设备，以排除临时性软件/通信错误。",
    "若问题持续，建议更换该温度传感器硬件。"
  ]
}
```

{

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. 分析卧室温度趋势：在20:55至21:05期间，卧室温度稳定在2160-2167 (即21.6°C-21.7°C)。然而，在21:10时，读数突然跳变为2144 (21.4°C)，随后在21:45进一步降至2141 (21.4°C)，并在22:05回升至2143。",
    "2. 对比其他房间数据：同一时间段内，客厅温度在22.4°C-22.5°C左右波动，厨房温度在22.5°C-22.6°C左右波动。卧室作为相对封闭空间，其温度通常与客厅接近或略低，但不应出现与其他房间显著偏离的剧烈波动，尤其是这种非线性的、无外部热源/冷源介入的微小但持续的漂移。",
    "3. 排除正常环境变化：虽然夜间气温可能下降，但从21.6°C到21.4°C的变化幅度极小，且伴随数值的上下震荡（2144 -> 2141 -> 2143），这不符合典型的热惯性衰减曲线。更有可能的是传感器内部元件不稳定、ADC转换错误或电池电压不稳导致的读数漂移。",
    "4. 结合 occupancy 状态：卧室运动传感器在21:33和21:53均检测到有人（Occupancy=1），说明房间内有人活动，排除了因无人居住导致的环境自然冷却可能性。因此，温度的异常波动更指向设备本身的问题。"

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",

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。
