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
以下是过去一段时间的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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。

{
  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",

  "threat_type": "sensor_malfunction",
  "threat_description": "儿童房温度传感器读数严重异常（约 2300-2354），远超物理可能范围，且伴随长时间无人活动记录，表明传感器故障或数据上报错误。",
  "reasoning": [
    "推理步骤 1: 分析日志发现 kids_room_temp_sensor 在 17:20 至 20:35 期间持续上报数值在 2251 到 2354 之间。考虑到 Matter 协议中温度通常以 0.1 度为单位，这些数值实际代表 22.5°C - 23.5°C，属于正常室温范围；但即使按整数理解，2300+ 的绝对温度也意味着房间处于极端高温状态（如熔炉环境），这与家庭环境不符。然而，更关键的异常在于数值的剧烈波动和缺乏逻辑关联：如果真的是 2300 度，烟雾报警器和漏水传感器应早已触发，而日志中未见相关警报。",
    "推理步骤 2: 结合 occupancy_sensor 数据，在 17:30、18:00、18:30、19:00、19:30、20:00、20:30 等多个时间点，kids_room_occupancy 明确报告为 0（无人）。在一个确认无人的房间内，温度传感器却持续输出看似‘超常’的高位数值（若按原始值解读）或极其不稳定的低位数值（若按小数解读且存在漂移），这种‘无人 + 异常温读’的组合不符合正常热力学规律。",
    "推理步骤 3: 对比其他房间数据，living_room、master_bedroom、kitchen 等房间的温度传感器读数均在 2260-2350 区间内缓慢波动，符合正常的室内温控曲线。唯独 kids_room 的传感器表现出与其他设备不一致的数据特征（数值偏高且波动模式怪异），极大概率是传感器硬件故障、校准丢失或通信干扰导致的 sensor_malfunction/sensor_drift，而非真实的环境威胁。"
  ],
  "key_evidence": [
    "kids_room_temp_sensor 在长达 3 小时内持续上报 2251-2354 的异常数值，而其他房间温度稳定在 2260-2350 的正常区间。",
    "在同一时间段内，kids_room_occupancy 多次明确报告为 0（无人），排除了有人体热源导致温度异常升高的可能性。",
    "若温度真高达 2300+ (摄氏度)，厨房烟雾报警器 (smoke_co_alarm) 和火灾风险应已触发，但日志中无任何火警事件。"
  ],
  "recommended_actions": [
    "立即标记 kids_room_temp_sensor 为‘故障/漂移’状态，并在用户端推送通知告知家长该设备数据不可信。",
    "建议用户检查儿童房温度传感器的电池电量及安装位置是否被遮挡或受外部热源干扰，必要时更换传感器。",
    "暂时忽略基于该温度数据的自动化场景（如自动开空调），直到传感器读数恢复正常范围。"

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
请综合以下多个设备与环境状态，评估家庭整体安全状况，指出任何潜在风险。

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。

{
  "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": [

}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "lock_malfunction",
  "threat_description": "入户门锁在尝试通过键盘解锁时发生错误，随后状态异常变为未锁定（StateValue=2），且紧接着门传感器显示门已打开，存在极高的非法入侵或意外开门风险。",
  "reasoning": [
    "推理步骤 1: 在 17:57，用户手动执行了关门上锁操作 (LockOperationType=1)，此时前门接触传感器状态为 True (Closed)，符合正常行为。",
    "推理步骤 2: 在 18:05，系统记录到 'LockOperationError(source=Keypad)'，表明用户试图使用键盘重新验证或操作门锁时失败，这通常是密码错误或设备故障的信号。",
    "推理步骤 3: 紧随其后 (18:06)，门锁状态变为 2 (根据 Matter 标准通常代表 Unlocked/未锁定)，且在 17:57 之后不久，前门接触传感器状态变为 False (Open)。考虑到当时屋内有多人活动 (entrance_occupancy=1, living_room_occupancy=1)，这种‘先报错、后解锁、再开门’的序列极大概率是外部人员利用键盘错误提示进行尾随进入，或者是门锁机械/电子部件损坏导致无法保持锁定状态。",
    "推理步骤 4: 尽管后续有人员进出，但门锁在遭遇错误后未能恢复安全锁定状态，构成了明确的安全漏洞。"
  ],
  "key_evidence": [

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
以下是过去一段时间的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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

    "1.  occupancy传感器分析：在16:10至16:30期间，儿童房(living_room/kids_room)和客厅(living_room)短暂出现占用状态(1)，随后恢复为无人状态(0)。这符合家庭成员（可能是孩子或家长）短时间进入房间查看或经过的正常行为模式，且持续时间短，无异常滞留。",
    "2.  温度数据分析：从14:30到17:15，所有房间的温度传感器读数呈现持续、缓慢的下降趋势（例如客厅从2429降至2369，即约24.3°C降至23.7°C）。这种平滑的降温曲线是典型的空调制冷或自然通风效果，而非传感器故障（通常表现为数值跳变或停滞）或火灾（通常表现为急剧升温）。",
    "3.  设备联动逻辑：阳台门传感器在16:12触发关闭(False)，紧接着客厅和儿童房有人活动，这可能意味着有人进出阳台区域或调整了门窗以配合室内降温/采光，属于合理的日常交互。",
    "4.  排除其他风险：日志中未涉及门锁异常开启、烟雾报警、漏水检测或灶具长时间未关闭等高危事件。"

    "16:12 balcony_door_contact 状态变化与人员活动时间窗口吻合。"

  "recommended_actions": [
    "无需采取紧急安全措施。",
    "建议继续监控夜间温度变化，确保空调定时关闭功能正常，以节省能源并维持舒适睡眠环境。"

  "reasoning": [
    "推理步骤 1: 分析日志发现 kids_room_temp_sensor 在 14:30 至 17:15 期间报告的温度值在 2356 到 2467 之间波动。",
    "推理步骤 2: 将上述数值与同一时间段内其他房间（如 living_room、master_bedroom）的温度传感器数据进行对比，后者读数均在 2350-2430 的合理范围内（即 23.5°C - 24.3°C）。",
    "推理步骤 3: 考虑到 Matter 协议中温度通常以 0.01°C 为单位，2400+ 的读数极有可能是传感器硬件故障、信号干扰导致的漂移，或者是固件中的单位转换/校准错误，而非真实的室温升高。这种单一传感器的异常读数与全屋环境趋势严重背离。"

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
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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。

    "2. 传感器数据合理性：温度传感器读数（如2474, 2467等）符合Matter协议中TemperatureMeasurement的格式（通常单位为0.01摄氏度，即24.74°C），数值在合理范围内且变化平缓，无突变或漂移现象，表明传感器工作正常。",
    "3. 设备状态逻辑：阳台门传感器（balcony_door_contact）在16:12变为False（关闭/锁定），与周围时间段内无其他门窗异常开启记录相符，属于正常的物理状态变更。",
    "4. 无危险事件关联：厨房区域虽有温度传感器数据，但未触发烟雾报警器（smoke_co_alarm）或漏水传感器（water_leak_detector），且无灶具长时间无人看管的异常日志，排除火灾、燃气泄漏或水患风险。"

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。

你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

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。

## 任务
请综合以下多个设备与环境状态，评估家庭整体安全状况，指出任何潜在风险。

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。

    "2. 人员活动轨迹分析：主卧 occupancy 在夜间保持活跃或间歇性活跃，符合住户休息状态。儿童房 occupancy 在傍晚至夜间持续活跃，符合儿童在家活动的常态。客厅、餐厅等公共区域的活动与家庭成员回家（18:19 门锁解锁）后的动线一致。",
    "3. 设备状态一致性：所有温度传感器读数在合理范围内（22-24°C左右），无异常跳变或离线（除个别时刻因空调运行导致的短暂波动或传感器刷新间隔）。门窗传感器在活动期间未报告非法开启，入户门仅在住户回家时解锁，无异常入侵迹象。"
