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": [
    "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": [

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "厨房灶具在无人看管的情况下被开启，且随后检测到温度异常波动，存在极高的火灾风险。",
  "reasoning": [
    "推理步骤 1: 在 2026-08-27T12:05:00，日志显示 kitchen_cook_surface (厨房灶具) 状态变为 True (开启)。",
    "推理步骤 2: 此时及之后的一段时间内 (12:05 - 12:30)，living_room_occupancy、master_bedroom_occupancy、second_bedroom_occupancy 均为 0，且 entrance_occupancy 仅在 12:06 和 12:26 短暂出现（可能为路过或宠物），没有确凿证据表明有人正在厨房区域活动。",
    "推理步骤 3: 在 12:12:00，kitchen_temp_sensor 读数从正常的 ~2530 mK (~25.3°C) 突然跳变至 2920 mK (~29.2°C)，随后又回落。这种非线性的温度骤升可能是燃气泄漏导致局部燃烧、设备故障过热或传感器受到热辐射干扰的迹象，结合无人看管的灶具状态，构成了严重的火灾隐患。"
  ],
  "key_evidence": [
    "2026-08-27T12:05:00 kitchen_cook_surface OnOff.OnOff = True",
    "2026-08-27T12:12:00 kitchen_temp_sensor TemperatureMeasurement.MeasuredValue = 2920 (显著高于周围室温)",
    "同期多个房间 occupancy 传感器报告为 0，缺乏有人在厨房活动的直接证据"
  ],
  "recommended_actions": [
    "立即通过 Matter 协议远程关闭厨房灶具 (kitchen_cook_surface OnOff.OnOff = False)。",
    "检查厨房烟雾报警器 (smoke_co_alarm) 是否触发，并确认现场是否有烟雾或异味。",
    "通知住户回家检查厨房安全状况，确认是否存在燃气泄漏或设备损坏。",

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

  "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
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。

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。

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": [
    "推理步骤 1: 行为模式分析显示，用户在 18:30 开启厨房灯和灶具，但在 19:20 关闭了灶具。然而，从 19:20 到 19:25（仅 5 分钟），厨房温度传感器读数从正常的约 23°C (2300 mK) 瞬间跳变至 28.6°C (2860 mK)，并在 19:35 进一步升至 27.4°C (2740 mK)。这种升温速率远超正常烹饪结束后的余热衰减速度，表明可能有明火复燃、燃气泄漏燃烧或设备故障导致的高温积聚。",
    "推理步骤 2: 人员状态与设备状态不匹配。日志显示在 19:20 关闭灶具后，直到 19:35 之前，客厅、主卧、次卧的 occupancy 传感器均检测到有人活动（Occupancy=1），但厨房区域没有明确的 Occupancy 报告（或默认视为无直接关联的高频占用确认）。更关键的是，如果用户正在家中其他房间活动，而灶具在关闭后迅速产生高温，这属于典型的‘未受监控烹饪’或‘操作失误’场景。",
    "推理步骤 3: 数据异常性验证。Matter 协议中温度通常以毫开尔文 (mK) 为单位，2300 对应 23°C，2860 对应 28.6°C。虽然 28.6°C 本身不是致命高温，但结合上下文：灶具刚关闭，温度却出现非线性的剧烈波动（先升后降但仍高于初始值），且伴随之前的多次短暂启停（18:30-18:59, 19:00-19:20），这表明烹饪过程极其不稳定，极有可能是油锅起火初期被扑灭后复燃，或者传感器因靠近火源/热浪而受到干扰。考虑到烟雾报警器未在日志中触发报警事件，可能存在延迟或尚未达到阈值，但这已是严重的前兆。"

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。

    "随后在 10:04:00，厨房烟雾报警器返回 TestInProgress = False，表明测试流程正常结束。结合此前客厅温度传感器读数稳定在25.4-25.6°C左右，无异常升温迹象，进一步证实这是正常的设备测试行为。"
