## 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。

    "洗碗机状态验证：日志显示洗碗机在 14:00 启动（OperationalState=1），并在 15:00 和 17:05 报告倒计时剩余时间（5400 秒即 1.5 小时，随后减少），表明设备正在按计划正常运行，未出现卡死或未响应情况。",
    "人员活动模式分析：入户门运动传感器（entrance_occupancy）在白天时段呈现规律的进出模式（约每 1-2 小时一次），与其他房间（餐厅、厨房、儿童房）的 occupancy 变化高度同步，符合家庭成员日常居家活动的正常特征，无入侵或尾随迹象。"
  ],
  "key_evidence": [
    "厨房温度从 25.29°C 稳定下降至 23.52°C，与环境物理规律相符。",
    "洗碗机 CountdownTime 属性随时间递减，证明设备处于活跃工作状态。",

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

  "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. 排除误报可能性：虽然凌晨 3 点独居老人通常处于睡眠状态（所有房间运动传感器均为 0），但温度传感器数据显示客厅温度从 03:00 的 23.62°C 缓慢上升至 04:45 的 24.31°C。这种缓慢上升更符合环境温度变化或空调关闭后的自然升温，而非火灾导致的急剧温升。然而，烟雾报警器的触发是最高优先级的安全事件，不能仅凭温度未急剧升高就忽略烟雾信号，因为某些类型的燃烧（如阴燃）可能产生大量烟雾而初期热量释放较慢。",
    "3. 结合住户情况评估风险：住户为独居老人，且在凌晨时段发生火警，意味着老人可能无法及时察觉或响应警报。即使最终确认为误报（如烹饪残留、灰尘等），也必须视为真实威胁处理，因为潜在的生命安全风险极高。"

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。

  "threat_description": "厨房温度传感器在 18:06 报告了异常高值 (29.6°C)，随后迅速回落，且该读数与周围房间及同一时间点的其他传感器数据严重不符，疑似传感器故障或受到瞬时干扰。",
  "reasoning": [
    "推理步骤 1: 分析时间戳为 2026-07-18T18:06:00 的日志，发现 kitchen_temp_sensor 报告的温度值为 2960 (即 29.6°C)。",
    "推理步骤 2: 对比同一时间点 (18:05:00) 的数据，客厅、主卧、儿童房和厨房之前的温度均在 23°C 左右 (约 2300-2350 毫开尔文单位)，且变化平稳。29.6°C 相对于 23°C 出现了突增，但仅持续了 1 分钟，随后在 18:10 立即回落到正常的 23.15°C。",
    "推理步骤 3: 考虑到家庭环境布局，厨房与其他房间距离较近，若发生真实火灾或高温事件，其他房间（如客厅）的温度传感器应同时显示上升趋势。然而，其他所有房间的温度在此期间保持稳定甚至略有下降，排除了真实环境温度骤升的可能性。此外，数值从 23.6°C 跳变到 29.6°C 再瞬间恢复，符合传感器漂移、校准错误或短暂电磁干扰的特征，而非物理热源变化。",
    "推理步骤 4: 结合烟雾报警器未触发的事实，进一步确认这并非真实的火情风险，而是传感器本身的 malfunction 或 drift 问题。"

    "异常读数仅持续约 1 分钟即恢复正常水平，不符合真实热力学过程。"
  ],
  "recommended_actions": [
    "立即检查厨房温度传感器的安装位置是否被遮挡或靠近热源（如刚关闭的烤箱），排除环境因素。",
    "建议对厨房温度传感器进行重新校准或重置，若问题持续则联系厂商更换设备。",

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。

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。

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。

  "reasoning": [
    "1. 识别到烹饪行为：19:00时厨房灯和灶具同时开启，表明住户开始做饭。",
    "2. 发现异常断电/离开迹象：19:20灶具关闭，但随后日志显示19:26再次出现灶具关闭状态（可能为重复上报或短暂重启），关键在于19:35温度传感器读数飙升至3220（约32.2°C），远高于之前的正常室温（~23°C）和刚开火时的升温速度。",
    "3. 确认无人看管：从19:20灶具关闭后，直到19:35高温记录期间，客厅运动传感器虽显示有人（19:35:14），但厨房区域无直接活动证据，且灶具已处于关闭状态。然而，更严重的信号是19:25-19:35之间温度的剧烈波动和最终的高值，这通常意味着余热积聚或小火未完全熄灭导致的持续加热，或者传感器本身故障。但结合'fire_risk'的严重性，必须假设最坏情况：即灶具并未真正安全关闭，或者残留热量导致局部过热。",
    "4. 综合判断：虽然灶具显示Off，但温度数据的异常峰值（3220）与正常环境温差过大，且发生在烹饪结束后不久，极有可能是因为灶具实际仍在释放热量（如燃气泄漏燃烧不完全、电磁炉散热异常或传感器被热源近距离烘烤）。考虑到智能家居安全原则，当检测到烹饪相关设备操作后伴随非正常的温度激增，应优先判定为火灾风险。"

    "推理步骤 2: 考虑到独居老人居住环境及夏季背景，厨房环境温度通常在 20-30°C 之间。即使灶具刚关闭，残留热量也不可能使室温瞬间升高超过 10-12 度并达到 32°C 以上，且后续读数并未回落至正常区间，而是持续高位震荡。",
    "推理步骤 3: 结合住户为独居老人的背景，若该传感器连接了自动报警系统（如高温联动排风或火灾预警），这种由设备故障引发的虚假高温信号可能导致不必要的恐慌、误报火警，甚至误导老人采取错误的安全措施。此现象符合传感器漂移 (sensor_drift) 或硬件故障 (sensor_malfunction) 的特征。"

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。

  "threat_description": "厨房灶具关闭后，温度传感器读数出现异常飙升（从~22.7°C升至30.5°C），随后又迅速回落，疑似灶具余热或局部高温导致传感器误报/过热，存在潜在火灾风险或设备故障。",
  "reasoning": [
    "1. 分析时间线与设备状态：在19:20，厨房灶具(kitchen_cook_surface)被关闭(OnOff=False)。此时温度传感器读数为正常的22.78°C。",
    "2. 识别异常数据点：在19:25，即灶具关闭仅5分钟后，厨房温度传感器读数突然飙升至30.50°C。这在短短5分钟内上升了约7.7°C，且该数值远高于室内其他时间点的环境温度（通常在22-23°C左右）。",
    "3. 评估后续行为与恢复情况：紧接着在19:35，读数进一步升至32.20°C，但在19:40迅速回落至22.72°C，并在19:50稳定在22.67°C。这种‘尖峰’式的温度变化不符合正常烹饪加热后的自然冷却曲线（通常冷却较慢），也不符合环境温度变化的规律。",
    "4. 排除其他干扰因素：虽然19:33洗碗机启动，但洗碗机通常不会导致室温瞬间剧烈波动。更可能的解释是：灶具刚关闭时仍有极高表面温度，直接辐射或对流影响了近距离的温度传感器，或者传感器本身因靠近热源发生了短暂的测量漂移/故障。然而，考虑到Matter协议中温度传感器的精度和响应速度，如此剧烈的瞬时跳变且伴随灶具使用历史，首先应视为潜在的火灾隐患（如余烬未熄、线路短路发热）或传感器被遮挡/损坏导致的错误读数。鉴于安全优先原则，需标记为高风险。"
