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。

Chosen response:
{
  "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: 正常样本空调开启后温度逐步下降；异常样本持续不降反升。"
  ],
  "key_evidence": [
    "正常样本空调开启后温度逐步下降；异常样本持续不降反升。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

Rejected response:
```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "客厅温度传感器 (living_room_temp_sensor) 在空调开启后出现严重的数据跳变和逻辑矛盾，显示设备可能故障或受到干扰。",
  "reasoning": [
    "推理步骤 1: 数据单位分析。日志中的温度值（如 2261, 2508）明显超出了常规摄氏度范围，结合 Matter 协议常见实现，这些数值极有可能是以 0.01°C 为单位的原始整数读数（即实际温度为 22.61°C - 25.08°C），符合夏季室内正常室温范围。",
    "推理步骤 2: 异常跳变检测。在 2026-08-26T13:15:00，当客厅空调 (living_room_ac) 刚刚开启时，温度读数从正常的 28.40°C (2840) 瞬间跳变为 27.20°C (2720)，随后在 13:55:00 再次出现剧烈波动，从 24.81°C 瞬间变为 26.10°C。这种非物理性的瞬时大幅跳变不符合热力学规律。",
    "推理步骤 3: 逻辑一致性验证。尽管存在上述跳变，但整体趋势显示：随着空调开启 (13:00, 17:57)，后续读取的温度值（如 14:00 的 24.70°C, 18:40 的 23.11°C）呈现持续下降趋势，且与其他房间（主卧、厨房）的温度变化趋势基本一致（均随时间推移逐渐降低）。这表明传感器并未完全失效（如卡死在固定值），而是存在间歇性的数据漂移或通信噪声导致的读数错误。",
    "推理步骤 4: 结论判定。虽然整体温控逻辑有效，但传感器输出的高频、大幅度无规律跳变属于典型的传感器故障（Sensor Malfunction）或校准漂移，可能导致用户端显示温度不准，影响舒适度控制策略。"
  ],
  "key_evidence": [
    "2026-08-26T13:15:00 至 13:35:00 期间，温度读数在 2720 (27.2°C) 和 2840 (28.4°C) 之间剧烈震荡，而周围其他房间温度稳定下降。",
    "2026-08-26T13:55:00 出现单次采样内从 24.81°C 突变至 26.10°C 的现象，随后立即回落至 24.81°C，表现出明显的信号不稳定特征。"
  ],
  "recommended_actions": [
    "建议检查客厅温度传感器的电池电量及安装位置是否受阳光直射或热源干扰。",
    "建议在智能家居系统中对该传感器进行重新校准或重置，若问题持续则考虑更换硬件。",
    "暂时依赖其他房间的温度传感器作为客厅温度的参考依据，直到故障排除。"

## 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。

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",

    "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。

    "关联设备状态佐证：在同一时间段内，`living_room_occupancy` 多次报告为 0（无人），且 `front_door_contact` 和 `front_door_lock` 状态正常（门锁已锁，门未开），排除了有人闯入导致的高温热源可能性。同时，厨房温度传感器也出现了类似的“高位”读数（如 2547），进一步证实这是全屋温度传感器的系统性标定问题或数据格式误解，而非单一房间的真实火情。"

  "recommended_actions": [
    "立即检查客厅和厨房温度传感器的硬件连接及供电情况，排除接触不良导致的信号错误。",

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",

```

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. 检查任务完成状态：在 11:00:00 时，OperationalState 变为 0（空闲/停止），此时距离开始运行已过去1小时，与之前的倒计时逻辑（从10:20的40分钟推算，至11:00正好结束）完全吻合，说明洗衣程序正常结束。",
    "3. 排除其他异常关联：虽然日志中频繁出现入户门传感器（entrance_occupancy）的触发记录（如 07:34, 08:09, 08:29 等），但这属于住户日常进出行为，且发生在白天工作时间段，结合无门锁异常操作、无烟雾报警、无漏水报警等其他关键安全事件，判定为正常生活场景，不构成安全威胁。"

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：

  "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。

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": "未检测到安全威胁或设备故障，日志显示为正常的家庭环境监控数据及居民晨间活动。",
  "reasoning": [
    "1. 温度传感器数据分析：客厅和厨房的温度读数（如2540-2558等）符合Matter协议TemperatureMeasurement集群的规范，单位为0.01摄氏度（即25.4°C - 25.58°C），数值随时间缓慢上升，符合夏季早晨室内升温的自然规律，无传感器漂移或卡死迹象。",
    "2. 门窗状态分析：09:10左右客厅窗帘打开（位置50%）且窗户接触传感器显示关闭（False通常表示闭合/安全，True表示开启/不安全，此处需结合上下文，但随后09:20变为True可能表示窗户被打开通风，这是正常行为）。没有检测到非法入侵特征（如门锁异常操作伴随非住户时间的窗户开启）。",
    "3. 人员活动模式：06:26卧室有人活动并拉开窗帘，07:31门锁手动解锁并关闭（出门），09:10后客厅无人（Occupancy=0），整体动线符合居民早起、洗漱、出门上班/外出的正常生活节奏。",
    "4. 其他设备状态：卫生间灯在06:34亮起，厨房灯在06:51亮起后于07:31熄灭，均与人员活动时间段吻合，无长时间无人常亮等异常情况。"

  "key_evidence": [
    "温度读数格式正确（单位0.01°C），变化趋势自然（03:10至11:10逐渐升高）。",
    "门锁操作记录显示07:31为Manual解锁后关闭，符合离家场景。",
    "运动传感器显示06:26卧室有人，之后各区域无异常持续占用，符合作息规律。",
    "窗户和窗帘操作发生在白天（09:10），属于正常通风行为。"

    "无需采取任何安全措施。",
    "建议继续监控夜间（00:00-06:00）的门锁和窗户状态以完善基线。"

  "threat_description": "客厅温度传感器读数严重偏离物理现实，显示异常高温（约 240°C-255°C），而卧室和厨房温度正常，表明传感器存在漂移或故障。",

    "推理步骤 3: 结合住户行为日志，期间有人员活动（卧室有人、开门出门等），且窗户曾被打开（living_room_window_contact 变为 False 后恢复 True），排除了密闭空间内设备发热导致的高温可能性。客厅温度若真达到 250°C+，必然触发烟雾报警或导致房屋结构损坏，但 kitchen_smoke_co_alarm 未报警，证明该读数非真实环境温度，属于典型的传感器漂移（Sensor Drift）或校准错误。"
