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 3 天的设备活动记录。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",

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。

    "推理步骤 1: 分析 occupancy_sensor 数据发现，在 2026-07-29、30、31 的凌晨 03:14 左右，living_room_occupancy 均从 0 变为 1，但在约 5-10 分钟后（03:30）又迅速变回 0。这种‘短促出现 - 快速消失’的模式在独居老人场景中高度符合夜间起夜（去卫生间）或短暂不适后的行为特征。",
    "推理步骤 2: 结合 temperature_sensor 数据分析，在老人活动的同时（03:14 - 04:50），客厅和厨房的温度持续上升（例如 7/29 从 23.7°C 升至 24.3°C）。考虑到此时段为深夜且无人长时间停留，温度持续攀升极有可能是空调或暖气设备未根据人员离开而自动关闭，或者老人为了取暖/降温长时间开启了设备，存在健康风险（过热或过冷）。",
    "推理步骤 3: 对比三天日志，该模式具有高度的重复性和规律性（每晚同一时间发生），排除了随机入侵或偶然事件的可能性。对于独居老人而言，这种规律的夜间活动配合环境参数异常，是典型的潜在健康隐患信号（如睡眠障碍、夜尿症或心血管问题导致的夜间觉醒）。"

    "检查并配置智能温控策略：当检测到房间 occupancy 为 0 且持续时间超过设定阈值（如 15 分钟）时，自动将空调/暖气调至节能模式或关闭，防止能源浪费及极端温度对老人造成危害。",

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
系统刚记录到以下一段设备状态变化。请评估这些变化是否已经构成安全风险，并说明原因。

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",

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。

    "推理步骤 2: 关联设备状态，在 2026-07-24T03:15:00 这一关键时间点，厨房灯光（kitchen_light）被意外开启。考虑到此时老人刚从客厅短暂活动结束并离开，若其处于清醒且行动自如的状态，通常会直接前往卧室休息或去卫生间，而非特意打开厨房灯。这暗示老人可能在移动过程中因视线不清或身体失衡误触了开关，或者是为了寻找光源而进行的慌乱操作。",
    "推理步骤 3: 结合用户画像，针对‘独居老人’这一高风险群体，任何非典型的深夜异常活动轨迹都应被视为潜在的健康危机信号（如跌倒、中风前兆等）。连续三天在同一时间段发生类似事件，表明这可能是一个重复发生的健康隐患，而非偶然的随机行为。"

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
请根据以下设备记录评估当前是否需要安全响应；若需要，请说明原因与处置建议。

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",

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。

## 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": [
    "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。

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "intrusion",
  "threat_description": "检测到凌晨时段门窗被打开且有人活动，存在极高的非法入侵风险。",

    "1. 时间异常：事件发生在凌晨 02:31 至 02:34 之间，这是独居老人通常处于深度睡眠的时间段，任何非计划内的活动都极具可疑性。",
    "2. 物理入侵迹象：日志显示 living_room_window_contact (客厅窗户传感器) 和 bedroom_window_contact (卧室窗户传感器) 在极短时间内（约3分钟内）状态变为 False（即窗户被打开）。对于独居老人而言，深夜同时打开客厅和卧室窗户的可能性极低，这通常是入侵者进入或试图进入的路径。",
    "3. 人员活动确认：在窗户打开后仅2分钟（02:34），living_room_occupancy (客厅 occupancy_sensor) 检测到有人 (Occupancy = 1)。结合之前的窗户开启事件，这表明有人在深夜进入了客厅区域。",
    "4. 排除误报：虽然温度传感器数据波动较大，但 Occupancy 和 Contact 传感器的联动逻辑（开窗->有人出现）强烈指向人为的物理入侵行为，而非设备故障或自然现象。"

    "推理步骤 1: 在凌晨 02:31 和 02:32，客厅 (living_room) 和卧室 (bedroom) 的窗户接触传感器状态变为 False（打开），此时所有房间的运动传感器均显示为 0（无人）。",
    "推理步骤 2: 窗户开启后，从 02:34 开始，客厅运动传感器短暂检测到人影（Occupancy=1），但在 03:00 及之后再次变为 0。这表明有人进入并离开，或者设备误报，但结合后续温度变化，更倾向于有人进入室内活动。",
    "推理步骤 3: 最关键的风险信号是温度趋势：在窗户开启且人员离开（03:00 后全员无活动）的情况下，客厅温度从 02:35 的约 23.4°C 持续攀升至 04:05 的约 24.1°C，并在日志末尾达到 24.1°C（原始值 2410）。对于独居老人家庭，夜间室温在无热源情况下不应如此显著上升，这强烈暗示室内有未熄灭的火源、电器过热或人为纵火行为。",
