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
监控系统标记了潜在异常。请分析下面的日志，判断是否需要采取响应措施，并给出建议。

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": [
    "推理步骤1: ...",
    "推理步骤2: ...",
    "推理步骤3: ..."
  ],
  "key_evidence": [
    "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": [
    "推理步骤1: 正常样本只有厨房局部升温并伴随灶具开启；异常样本是多房间同步升温。"
  ],
  "key_evidence": [
    "正常样本只有厨房局部升温并伴随灶具开启；异常样本是多房间同步升温。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器报告了异常高的数值（约 29.2°C），且该读数在设备开启后出现剧烈波动，随后迅速回落至正常范围，表明传感器可能发生故障或校准错误。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，在 2026-08-04T12:12:00 时，kitchen_temp_sensor 报告的 MeasuredValue 为 2920。根据 Matter 协议及常见智能家居传感器的数据格式，这极有可能是 29.2°C 的浮点数被误报为整数，或者是传感器发生了严重的读数漂移/故障。",
    "推理步骤 2: 对比上下文，该异常读数发生在 kitchen_cook_surface (灶具) 于 12:05:00 开启之后。虽然烹饪会产生热量，但通常不会导致室温瞬间飙升至接近 30°C（除非是极端情况，但结合后续数据看可能性极低）。",
    "推理步骤 3: 关键证据在于读数的不稳定性。在 12:12:00 达到峰值 2920 后，仅过 3 分钟（12:15:00）读数就骤降至 2517，并在随后的几分钟内稳定在 2500-2540 之间。这种“尖峰”现象不符合物理热传导规律，强烈暗示传感器本身存在硬件故障、软件 bug 或通信干扰导致的瞬时错误上报，而非真实的火灾风险。",
    "推理步骤 4: 尽管存在读数异常，但其他安全指标（如烟雾报警器未触发、漏水传感器无报警、门窗传感器状态正常）均显示系统处于受控状态，因此主要威胁判定为传感器故障而非真实的安全入侵或火灾。"
  ],
  "key_evidence": [
    "2026-08-04T12:12:00 厨房温度传感器读数突增至 2920 (疑似 29.2°C)，远超正常室内环境。",
    "该异常读数在 3 分钟内迅速回落至 2517 并趋于稳定，呈现典型的传感器瞬态故障特征。",
    "灶具开启时间 (12:05) 与温度峰值 (12:12) 间隔较短，且温度下降速度过快，不符合真实加热过程的热惯性。"
  ],
  "recommended_actions": [
    "立即检查厨房温度传感器的物理连接和电池状态，排除接触不良或电量不足问题。",
    "建议将厨房温度传感器标记为‘需维护’或暂时从自动化逻辑中移除，防止其错误数据触发空调或其他联动设备。",
    "联系设备制造商获取固件更新或技术支持，以修复可能的软件校准错误。"

    "推理步骤 1: 分析时间线发现，2026-08-14T19:00:00 厨房灶具 (kitchen_cook_surface) 被开启 (True)，但此时厨房运动传感器 (kitchen_occupancy) 直到 19:01:00 才报告有人，且后续人员频繁进出其他房间（如卧室、客厅），表明烹饪过程可能缺乏持续的有效监管。",
    "推理步骤 2: 关键异常点出现在 2026-08-14T19:25:00，厨房温度传感器读数从正常的约 23°C (2273mK) 瞬间跳变至 2860 (约 25.8°C) 和随后的 2740 (约 24.1°C)。虽然数值换算后看似不高，但在 Matter 协议中，TemperatureMeasurement.MeasuredValue 通常以毫开尔文 (mK) 为单位。若原始数据单位理解偏差或设备故障导致读数逻辑错误，需警惕；更可能的情况是，结合上下文，这是设备试图报警前的异常波动，或者用户误操作导致高温区域未被及时关闭。",
    "推理步骤 3: 最危险的信号是 19:20:00 灶具被关闭 (False)，但紧接着在 19:25:00 温度传感器出现剧烈波动（2289 -> 2860 -> 2273）。这种‘先关火’后‘温度剧变’的模式不符合正常物理规律（关火后温度应缓慢下降），暗示可能存在传感器故障、设备未真正断电、或是发生了快速升温事件（如油锅起火初期）导致传感器短暂过载或复位失败。考虑到独居老人背景，对火灾隐患的容忍度极低，必须视为高危。",
    "修正推理：重新审视 Matter 标准，2261 mK = 22.61°C - 273.15 = -250.54°C (不可能)。说明该设备的 MeasuredValue 并非直接 mK，或者是相对值/特定编码。假设系统内部已校准为摄氏度或其他单位，观察趋势：19:25 的 2860 远高于之前的 2300 左右。无论单位如何，短时间内数值翻倍且伴随灶具操作，属于典型的异常热事件特征。",
    "最终确认：灶具开启后，人员在多房间活动，存在‘离人烹饪’风险。随后温度读数出现非自然的剧烈跳变，极可能是火灾前兆或传感器因高温触发的保护性异常读数。"

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。

    "2. 排除真实火警：如果发生真实火灾，SmokeCoAlarm 通常会报告 AlarmState (如 Fire Detected) 或触发声光报警事件，而不是 TestInProgress 状态。此外，同一时间段内 kitchen_temp_sensor 的温度读数在 2536-2540 (即 25.36°C - 25.40°C) 之间波动，处于正常室温范围，没有急剧升温迹象，排除了高温导致的误报或真实火情。",
    "3. 检查关联环境数据：日志显示 ContaminationState = 0，表示传感器未检测到灰尘污染，进一步佐证了设备状态良好。同时，其他房间（客厅、卧室）的运动传感器均显示 Occupancy = 0，说明此时家中无人，符合进行设备自检或日常待机时的场景特征。",

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

  "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",

    "2. 验证环境背景：在自检发生的时间段及前后，所有房间的温度传感器读数稳定在 25.3°C - 25.6°C 之间（Matter协议中通常单位为0.01摄氏度，即2538代表25.38°C），无异常高温或剧烈波动，排除了真实火灾风险。",
    "3. 确认人员状态：全屋多个房间的 OccupancySensing.Occupancy 持续为 0，表明房屋内无人或处于非活跃状态。结合时间（上午10点），这可能是住户外出工作或孩子上学后的常态，与烟雾报警器的自检行为无冲突，也未发现入侵迹象。"

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
请分析下面的实时设备事件，判断是否需要将其视为异常安全事件。

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": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "检测到烟雾报警器正在进行自检（TestInProgress），这是正常的设备维护行为，未检测到火灾或故障风险。",
  "reasoning": [
    "1. 识别关键事件：日志中在 10:00:00 和 10:01:00 分别记录了 kitchen_smoke_alarm 和 living_room_smoke_alarm 的 SmokeCoAlarm.TestInProgress 属性变为 True。",
    "2. 分析事件性质：SmokeCoAlarm.TestInProgress = True 通常表示用户手动触发了烟雾报警器的自检功能，或者设备按计划执行定期自检。这是一个主动的、预期的状态变化，而非被动检测到的危险信号。",
    "3. 验证后续状态：在 10:04:00 和 10:05:00 左右，两个报警器的 TestInProgress 均恢复为 False，表明自检过程正常结束，设备状态恢复正常。",
    "4. 排除其他威胁：在此期间，温度传感器读数在 25°C 左右波动，属于正常室温范围；运动传感器显示住户在客厅、厨房等区域活动，无异常静止或跌倒迹象；无漏水、入侵或一氧化碳浓度异常的报告。"

  ],

    "无需采取紧急安全措施。",
    "建议确认该自检是否为老人主动操作，若为误触可指导其如何取消测试模式，或检查是否设置了自动定期自检计划。"

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。
