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. 识别异常点：在17:00:00，卧室温度传感器突然上报读数为2920 (29.2°C)。这一数值不仅远高于当前环境温度（客厅23.5°C，厨房23.5°C），也远高于该房间前一刻的读数（22.7°C）。",
    "3. 验证持续性：紧接着在17:35，同一传感器读数恢复至2242 (22.4°C)，与之前的趋势完全吻合。这种‘尖峰’式的瞬时跳变且无后续持续高温迹象，不符合真实物理环境变化（如空调开启或阳光直射通常会有更平缓的变化曲线或伴随其他设备状态改变）。",
    "4. 排除误报：虽然18:16有门锁手动操作和人员活动，但那是半小时后的事情，且当时卧室温度已恢复正常。因此，17:00的高温极大概率是传感器硬件故障、校准漂移或通信数据包损坏导致的单次错误读数。"

## 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：

```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。

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

  "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. 排除正常波动：温度值突然变为 'None' 通常代表数据包丢失、传感器断电、通信中断或硬件故障，而不是正常的温度变化。考虑到同一时刻其他传感器工作正常，且前后读数合理，这极大概率是厨房温度传感器的瞬时故障或连接问题。",
    "4. 综合评估：虽然未检测到入侵、火灾或漏水等直接安全威胁，但关键环境监测设备的失效属于安全隐患，可能导致后续无法准确监控厨房环境（如过热或烟雾前的温度异常）。"

    "推理步骤 4: 综合来看，门锁被远程或物理强制开启，配合窗户的短暂开启/关闭以及多房间的人员活动，构成了完整的入侵证据链，排除了正常起床活动的可能性（因为老人通常不会在凌晨 3 点到 8 点之间长时间处于睡眠状态且室温持续上升而不调整空调）。"

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。

  "reasoning": [
    "1. 建立基准趋势：从07:00到13:00，随着室外气温升高和阳光照射，室内温度从22.76°C缓慢上升至约25°C左右。13:00时开启空调，随后各房间温度呈现一致的下降趋势（例如主卧从25.11°C降至24.60°C，厨房从25.04°C降至24.78°C）。",
    "2. 识别异常点：在13:15、13:35和13:55三个时间点，客厅温度传感器分别报告了29.20°C、29.40°C和29.60°C的读数。",
    "3. 排除环境因素：此时空调正在运行（OnOff=True），且其他所有房间的温度都在稳定下降（表明整体环境温度在降低）。如果客厅温度真的升至近30°C，这通常意味着热源极大或空调失效，但这与其他房间的数据矛盾，且没有伴随任何灯光开启或人员活动（Occupancy始终为0）来解释这种局部高温。",
    "4. 确认故障模式：这些高值读数呈离散分布，且在非高值时间点（如13:10, 13:20, 13:30）读数回归正常范围（~24.9°C-25.0°C）。这种“正常-尖峰-正常”的模式是典型的传感器硬件故障、校准漂移或通信数据包错误特征，而非真实的环境变化。"

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。

    "分析卧室温度传感器（bedroom_temp_sensor）的数据序列：从15:40到16:35，温度从23.03°C平稳下降至22.69°C，符合傍晚自然降温趋势。",
    "在17:00:00时刻，日志显示两条记录：一条为22.64°C（正常延续），另一条突变为29.20°C。",
    "紧接着在17:10:00，温度迅速回落至22.53°C，并在后续时间（17:30-19:35）继续呈现正常的夜间降温趋势（降至21.71°C）。",
    "这种瞬间的、大幅度的数值跳变（+6.5°C）且无其他关联设备（如空调开启、窗户打开、人体长时间停留导致的热积累）支持该现象，极大概率是传感器硬件故障、电池电压不稳或通信干扰导致的“毛刺”数据，而非真实的环境温度变化。"
