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。

  "reasoning": [
    "1. 分析温度数据的合理性：Matter协议中TemperatureMeasurement.MeasuredValue的单位是厘氏度（centi-degrees Celsius），即数值需除以100得到摄氏度。正常室温通常在20-30°C之间（对应日志中的2000-3000）。",
    "2. 识别异常模式：在大部分时间段内，客厅温度传感器读数在2400-2560之间波动（约24-25.6°C），符合夏季室内空调环境下的正常表现。然而，在13:15、13:35和13:55三个时间点，读数突然飙升至2920、2940和2960（约29.2-29.6°C）。",
    "3. 排除环境因素：虽然29°C略高于设定值，但考虑到空调在13:00开启，且其他房间（卧室、厨房）温度并未同步出现如此剧烈的瞬时跳变（例如13:15时卧室为24.06°C，厨房为25.03°C），这种局部且孤立的剧烈跳变不符合热力学传导规律。",
    "4. 确认故障特征：这些高读数随后迅速回落至正常范围（如13:20回到24.87°C），呈现出典型的“毛刺”或“尖峰”噪声特征，而非缓慢的漂移或持续的高温报警。这表明传感器可能存在接触不良、ADC转换错误或固件Bug导致的偶发性数据损坏。"

## 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。

    "紧接着在17:50，读数恢复为22.31°C并继续正常下降，表明这并非持续的环境变化，而是一个孤立的异常点。这种瞬时尖峰通常由传感器硬件故障、电池电压不稳或通信干扰导致的数据包错误引起。"

    "如果问题持续出现，建议更换该温度传感器以排除硬件故障。",
    "暂时忽略该时间点的空调控制逻辑，避免误触发制冷/制热。"

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。

## 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。

  "reasoning": [
    "1. 环境背景分析：日志显示时间为7月12日白天，客厅空调在13:00开启制冷。此时段室内其他房间（主卧、儿童房、厨房）的温度传感器读数均在24°C-25°C左右，且呈现随空调运行逐渐下降的趋势（从~25°C降至~24°C），符合正常物理规律。",
    "2. 异常数据识别：客厅温度传感器在13:15、13:35、13:55三个时间点分别上报了2920 (29.2°C)、2940 (29.4°C)、2960 (29.6°C) 的数值。",
    "3. 逻辑矛盾验证：在空调持续制冷的情况下，客厅温度不仅没有下降，反而突然飙升至接近30°C，且该数值远高于同一时间段内其他所有房间的温度（高出约5°C）。这种局部且剧烈的温度升高无法用正常的热惯性解释，也不符合空调关闭后的升温曲线（因为空调是开着的）。",
    "4. 排除法：由于其他传感器工作正常，且空调本身正在运行（OnOff=True），可以排除全屋高温的可能。这种孤立的、非线性的、与设备动作相悖的数据跳变，最可能的原因是温度传感器硬件故障、校准失效或通信干扰导致的数据错误。"

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",
  "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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "sensor_malfunction",
  "threat_description": "洗衣机运行但倒计时不减少",
  "reasoning": [

    "推理步骤3: 与正常过程矛盾"
  ],
  "key_evidence": [

  ],
  "recommended_actions": [

  ]
}

```json
{

  "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，发现设备在 10:00:00 启动 (OperationalState=1)，并在后续时间点 (10:20, 10:40, 11:00) 持续报告倒计时时间 (CountdownTime=2400 秒，即 40 分钟)，表明设备正在按计划执行洗涤程序，未出现卡死、报错或意外停止。",
    "推理步骤 2: 分析环境上下文，虽然入户门传感器频繁检测到有人进入 (entrance_occupancy=1)，但这是正常的家庭日常活动模式（如家人进出），且没有伴随门锁被非法操作、窗户异常开启或入侵报警等关联事件。",
    "推理步骤 3: 检查其他关键传感器，温度数据波动符合夏季室内自然变化规律，未发现烟雾、漏水或火灾风险迹象；所有运动传感器读数与人员进出逻辑一致，无传感器漂移或故障特征。"
  ],
  "key_evidence": [
    "balcony_laundry_washer 在 10:00-11:00 期间连续上报 CountdownTime=2400，显示正常运行中。",
    "entrance_occupancy 的多次触发 (07:18, 07:43, 08:03 等) 均为正常的人员进出记录，无异常入侵特征。",
    "全时段内无任何 smoke_co_alarm, water_leak_detector 或其他安全设备的告警信号。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，系统运行正常。",
    "建议用户可继续监控洗衣机剩余时间，预计将在 11:40 左右完成当前周期。"
  ]

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

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
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。

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器读数异常（显示为None），且卧室温度传感器数值呈现非自然的剧烈波动，疑似设备故障或通信异常。",
  "reasoning": [
    "1. 分析厨房温度传感器：在 17:41:00，kitchen_temp_sensor 的读数变为 'None'，随后在 18:05:00 恢复为 2324。虽然中间有缺失，但结合上下文，这通常表示传感器离线、电池耗尽或通信中断。对于一个独居老人的家庭，关键区域（厨房）的安全监测设备失联是一个潜在风险点。",
    "2. 分析卧室温度传感器：从 17:20 到 20:25，bedroom_temp_sensor 的读数变化极不自然。例如，从 17:55 (2236) 到 18:00 (2228)，再到 18:20 (2221)，18:45 (2194)，19:10 (2186)，19:35 (2182)，19:40 (2171)，最后到 20:25 (2153)。这些数值在短时间内（约3小时）持续下降超过80个单位（假设单位为0.1摄氏度，即下降了8度；若为整数摄氏度则下降80度，均不符合正常室温缓慢变化的物理规律）。这种剧烈的、单向的漂移或跳变是典型的传感器故障特征。",
    "3. 排除环境因素：客厅温度相对稳定（2349 -> 2338 -> 2323 -> 2309 -> 2293... 缓慢下降，符合傍晚降温逻辑），而卧室温度却出现异常陡降，说明并非全屋环境温度骤变，而是特定传感器的问题。",
    "4. 综合判断：厨房传感器数据丢失和卧室传感器数据剧烈异常，指向硬件故障、校准失效或固件Bug，属于 sensor_malfunction。"
