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",

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：

```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: 正常余热会逐步回落；异常样本在关火后温度继续上升。"
  ],
  "key_evidence": [
    "正常余热会逐步回落；异常样本在关火后温度继续上升。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "厨房温度传感器检测到异常高温，且伴随灶具开启事件，存在严重的火灾风险。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，在 2026-08-18T19:25:00 时，厨房温度传感器读数从正常的约 23°C (2330 mK) 瞬间跳变至 2860 mK (约 25.8°C)，随后在 T19:35:00 进一步飙升至 2740 mK (约 24.1°C)。虽然数值换算后看似未达报警阈值，但结合上下文需重新审视单位或设备状态。",
    "推理步骤 2: 关键证据在于 2026-08-18T19:25:00 和 T19:00:00 的 `kitchen_cook_surface` (灶具) 状态为 `OnOff.OnOff = True`。用户开启了灶具。",
    "推理步骤 3: 对比其他房间温度（客厅、卧室均在 22-23°C 左右），厨房温度在灶具开启期间表现出非线性的剧烈波动和持续高位趋势（日志中多次出现 >2700 的读数，若单位为毫开尔文则对应约 24-25 度，但若考虑设备故障导致的漂移或实际环境温度极高导致传感器饱和/漂移，或者更可能的情况：这是 Matter 协议中常见的绝对温度值偏移问题，或者该传感器本身发生了故障漂移）。",
    "推理步骤 4: 最危险的信号是 19:25:00 的温度读数突变。通常灶具开启会导致温度缓慢上升，而此处出现了类似“断崖式”或“阶梯式”的异常读数变化，且后续读数并未随时间线性下降，反而维持在高位震荡。考虑到日志中早期数据（如 00:00 的 2267）与后期数据量级一致，这极有可能是传感器故障（Sensor Drift/Malfunction）或环境极端异常。然而，在安全分析中，**任何无法解释的高温读数配合烹饪设备开启，必须首先视为火灾风险**。此外，19:00:00 曾短暂丢失数据 (None)，随后恢复并出现异常高值，增加了设备不稳定的可能性。",
    "推理步骤 5: 综合判断，尽管没有直接触发烟雾报警器日志，但温度传感器的异常行为（特别是 19:25 后的持续高位和不稳定）加上灶具开启，构成了明确的火灾隐患。"
  ],
  "key_evidence": [
    "2026-08-18T19:25:00 厨房温度传感器读数异常跳变至 2860 (显著高于周围房间)",
    "同一时间点 (19:25:00) 厨房灶具 (cook_surface) 处于开启状态 (On)",
    "19:00:00 温度传感器曾报告 None (数据丢失)，随后恢复并显示异常高值，暗示设备不稳定或故障",
    "厨房温度在灶具开启期间未呈现正常的线性升温曲线，而是出现剧烈波动和平台期"
  ],
  "recommended_actions": [
    "立即通知住户检查厨房是否有明火、焦糊味或烟雾，确认灶具是否已关闭。",
    "建议住户手动检查厨房温度传感器是否被遮挡、损坏或接触不良，必要时更换传感器。",
    "如果住户不在家，建议远程关闭厨房电源或联系物业/安保人员上门排查。",
    "检查厨房烟雾报警器功能是否正常，确保其未被灰尘覆盖或电池电量不足。"

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。

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. 排除误报与威胁：Matter 协议中 'TestInProgress' 属性明确用于指示设备自检流程，而非火灾警报（Fire Alarm）。结合此时段家中有多人活动（卧室、餐厅、玄关等传感器均有 Occupancy=1 记录），且无其他异常环境数据（如温度骤升、漏水等），判定为人为触发的正常测试或设备自动周期性自检。"

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：

```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。

    "步骤 4: 考虑到住户为独居老人，虽然当前未触发烟雾报警（可能是独立设备或尚未联动），但错误的温度数据可能导致自动化系统误判（例如错误地关闭空调、错误地触发警报或无法正确监测真实火情），存在安全隐患。"

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：

```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: ...",

    "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。

    "1. 识别关键事件：日志在 10:00:00 显示 kitchen_smoke_alarm 和 living_room_smoke_alarm 的 SmokeCoAlarm.TestInProgress 属性变为 True，并在约 4-5 分钟后（10:04:03）恢复为 False。这是典型的智能烟雾报警器自检或手动测试行为。",
    "2. 排除真实火警：虽然两个区域的报警器同时进入测试状态，但日志中未出现 SmokeCoAlarm.AlarmState (如 Fire Alarm) 或 High CO Level 等真实报警信号。温度传感器数据在测试期间保持平稳（客厅~25.4°C，厨房~25.5°C），无异常升温，排除了因高温触发误报的可能。",
    "3. 结合住户行为分析：独居老人在上午 9:00-10:00 期间活动频繁（客厅、卧室、厨房、玄关均有 occupancy 记录），表明老人意识清醒且行动正常。此时进行设备维护或测试符合逻辑，且周围有人在场，若发生真实火情可立即响应。",
    "4. 结论：该事件为受控的设备测试行为，非安全威胁。"

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。
