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": [

}
```

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. 识别异常模式：在13:15、13:35和13:55三个时间点，客厅温度传感器突然上报了极高的数值（2920, 2940, 2960）。这些数值远高于其他所有传感器在同一时刻的读数（约2490-2500），且温差高达40-50个单位。",
    "3. 排除环境因素：虽然此时客厅空调开启（OnOff=True），但空调通常导致温度缓慢下降而非瞬间飙升。此外，随后的读数迅速回落至正常范围（13:40为2481，13:55后再次跳变但随后又恢复），这种间歇性的极端高值不符合物理热传导规律，极有可能是传感器内部元件故障、ADC转换错误或通信干扰导致的“毛刺”数据。"

## 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。

  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "actuator_stuck",
  "threat_description": "灯的 OnOff 与 Level 矛盾",
  "reasoning": [

    "推理步骤3: 更像执行/上报故障"
  ],

  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "目标设备 living_room_light_1 状态正常，无安全威胁或异常行为。",
  "reasoning": [
    "推理步骤 1: 检查目标设备日志，发现 living_room_light_1 在 20:10:00 被设置为关闭 (OnOff=False) 且亮度调至最低 (Level=180)，随后在 20:12:00 再次确认关闭状态。该操作符合用户手动调节灯光的习惯，非设备故障导致的意外断电或常亮。",
    "推理步骤 2: 分析关联传感器数据，living_room_occupancy 在 20:14:07 检测到有人进入，此时灯光已关闭但房间内有活动（温度持续监测中），这是典型的‘人进灯关’节能模式或用户偏好设置，属于正常家庭行为。",
    "推理步骤 3: 综合全量日志，入户门锁状态正常（先锁定后手动解锁），烟雾报警器和漏水传感器未触发警报，各房间 occupancy 变化逻辑连贯（如玄关有人->客厅有人->厨房有人），未发现入侵、尾随或设备卡死等异常模式。"
  ],

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": [

}
```

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。

    "排除环境因素：厨房灶具在18:42才关闭，17:00时并未使用明火或高温设备导致全屋升温；空调未在日志中显示开启制冷以抵消高温。因此，该孤立的高温读数极大概率是传感器硬件故障、电池电量不足导致的电压波动，或通信数据包错误。"

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
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",

  ],
  "recommended_actions": [

}
```

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。

  ],
  "key_evidence": [
    "front_door_contact 于 07:10:00 变为 True，随后 entrance_occupancy 在 07:15:29 检测到人员，行为逻辑一致。",

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

  "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。

  "threat_description": "客厅温度传感器读数异常偏高且数值格式疑似错误（未转换为摄氏度），同时伴随窗帘状态与接触传感器逻辑冲突，表明设备存在硬件故障或配置错误。",
  "reasoning": [
    "1. 温度数据异常：日志显示 `living_room_temp_sensor` 的 `TemperatureMeasurement.MeasuredValue` 在 2359 到 2558 之间波动。根据 Matter 协议标准，温度值通常以厘氏度（centi-degrees Celsius）为单位存储，即实际温度 = 读数 / 100。若按此标准，2359 代表 23.59°C，这是合理的室温。然而，如果该传感器固件错误或校准失效，直接上报原始 ADC 值或未正确缩放的值，会导致系统误判为极端高温（如 2359°C），或者如果单位是华氏度/其他非标单位，则数值完全不可信。考虑到厨房和卧室传感器读数也在类似范围（2400-2500+），且随时间缓慢上升，这更像是传感器本身的漂移或故障，而非真实的环境升温（因为室内不可能在短时间内从23度升到2500度）。",
    "2. 窗帘与接触传感器逻辑矛盾：在 09:10:00，`living_room_window` (窗帘) 的位置报告为 0%（通常表示完全关闭/放下），紧接着 `living_room_window_contact` (窗户接触传感器) 报告 StateValue = True（通常表示关闭/闭合）。但在 09:12:00，接触传感器变为 False（打开），而 09:15:00 窗帘位置仍为 0%。如果窗户物理上是开着的（接触传感器False），窗帘却显示完全关闭（0%），这在机械上是不可能的，除非传感器安装错误、损坏或通信出现严重不同步/错误。",
    "3. 综合判断：虽然住户可能正常活动（门锁操作、卫生间使用），但核心环境感知设备（温度、窗户状态）的数据一致性被破坏。特别是温度值的量级问题（如果是23.59度则正常，但结合上下文“分析健康问题”，通常指代数据异常；若视为2359度则明显故障。鉴于Matter标准是centi-Celsius，23.59度是正常的，但题目要求判断“设备健康问题”。让我们重新审视：如果2359是23.59度，那么所有读数都在23-25度之间，这是非常正常的夏季室温。但是，注意看 `living_room_window` 和 `contact_sensor` 的交互。09:10 窗帘0%，接触True -> 09:12 接触False -> 09:15 窗帘0%。如果接触传感器报False意味着窗户开了，那窗帘怎么可能是0%（关）？这说明至少有一个传感器在撒谎或故障。此外，温度读数在凌晨4点到早上9点持续上升（23.59 -> 25.51），在没有空调开启记录的情况下，这种线性且快速的升温（每小时约0.5-1度）对于封闭房间略快，但也可能在阳光直射下发生。然而，最明显的异常在于窗户系统的逻辑冲突。"

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
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。

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "客厅温度传感器读数出现剧烈且不合逻辑的跳变（从~25°C瞬间飙升至~29.4°C），随后又迅速回落，疑似传感器故障或数据上报异常。",
  "reasoning": [
    "1. 分析温度变化趋势：在13:00至13:15之间，客厅温度传感器读数从正常的25.42°C缓慢下降至25.17°C，符合夏季午后室内温度随空调运行或自然变化的规律。",
    "2. 识别异常点：在13:15:00，读数突然跳变为29.20°C；紧接着在13:35:00变为29.40°C；在13:55:00变为29.60°C。这些数值在短时间内大幅升高，且与同一时间段内其他房间（如卧室降至23.78°C，厨房降至24.96°C）的温度趋势完全背离。",
    "3. 排除环境因素：虽然13:00开启了客厅空调，但通常空调开启会导致温度逐渐降低而非升高。即使考虑阳光直射，温度也不会在几分钟内产生如此剧烈的阶梯式上升，且在14:20后读数又迅速回落到24.61°C的正常范围。这种“尖峰”式的波动不符合物理热惯性特征。",
    "4. 结合住户情况：独居老人家中，若真发生局部高温（如火灾前兆），烟雾报警器应触发，但日志中未显示smoke_co_alarm报警。因此，更可能是传感器本身硬件故障、校准丢失或通信数据包错误导致的虚假高值。"
