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
请从下面 3 天的时序日志中分析住户或环境是否出现异常模式，不要只看单个事件。

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": [
    "推理步骤1: ...",
    "推理步骤2: ...",
    "推理步骤3: ..."
  ],

    "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。

  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常模式，所有设备日志符合正常住户作息规律。",
  "reasoning": [
    "1. **作息规律性分析**：连续三天（7月31日-8月2日）的日志显示高度一致的作息模式。住户通常在清晨06:30-06:45之间起床（卧室/客厅 occupancy 变为 1），随后进行洗漱（浴室 occupancy 短暂活跃）和早餐准备（厨房灯开启）。这一模式在三天内完全重复，表明是稳定的日常行为，而非异常闯入或混乱行为。",
    "2. **离家与归家逻辑验证**：7月31日早晨07:15左右，入户门锁执行了手动解锁后上锁操作（LockOperation Type 1 then 0），且门磁传感器状态为 False（关闭），这符合典型的“出门上班”场景。此后直到当晚21:46才再次检测到客厅有人，中间长时间无活动，符合工作日白天的正常状态。",
    "3. **环境数据合理性**：温度传感器读数随时间缓慢变化（如清晨室温从24°C逐渐升至25°C以上），符合自然热力学规律及空调/通风设备的潜在调节作用，未发现传感器卡死（数值不变）或漂移（数值剧烈跳变）的迹象。",
    "4. **关键设备状态检查**：重点关注的 kitchen_light 仅在早晨和中午/傍晚等合理时间段开启，未见深夜无故亮灯；living_room_occupancy 的变化与灯光、人员活动逻辑一致，未发现非法入侵迹象（如深夜门锁异常开启或无人时门窗频繁开关）。"
  ],
  "key_evidence": [
    "连续三天早晨 06:30-06:45 出现一致的起床活动序列（卧室/客厅 Occupancy=1 -> 浴室活动 -> 厨房灯开）。",
    "7月31日 07:15 门锁手动操作记录与门磁关闭状态吻合，确认为正常离家行为。",
    "温度传感器数据呈现平滑的自然波动，无突变或停滞现象。"
  ],
  "recommended_actions": [
    "无需采取任何安全措施，系统运行正常。",
    "建议继续保持当前的自动化规则（如基于 occupancy 的灯光控制），以维持节能和安全监控的有效性。"
  ]
}
```

Rejected response:
{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "fire_risk",
  "threat_description": "这些变化表明存在安全异常。",
  "reasoning": [
    "推理步骤1: 我把本可由正常模式解释的事件误判成了异常。"
  ],
  "key_evidence": [
    "触发时间位于清晨起床窗口且有轻微抖动，不是固定的可疑重复模式。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"

    "2. 分析 occupancy 传感器数据：客厅和玄关的运动传感器在大部分时间（如 00:00-13:30, 14:30-23:30）均报告为 '0' (无人)。虽然这看起来像长时间无人，但结合温度传感器的读数变化（从 ~25°C 缓慢下降至 ~24.3°C），表明空调可能处于节能模式或自然降温，且没有异常的设备激活（如灯光、电器）。这种长时间的 '0' 状态更倾向于表示家中无人或人员主要在卧室休息而非公共区域活动，属于正常的生活节奏。",
    "3. 排除其他威胁：日志中未出现烟雾报警、漏水检测触发、窗户异常开启（除入户门外无其他门窗异常记录）、或者烹饪设备长时间开启等危险信号。温度读数在合理范围内波动，无剧烈异常。"

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
请从下面 3 天的时序日志中分析住户或环境是否出现异常模式，不要只看单个事件。

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",

    "5. **传感器数据稳定性**：温度传感器读数随时间缓慢上升（从凌晨~24°C升至上午~25°C），符合室内环境温度随日照和人体活动逐渐升高的物理规律，无突变或停滞现象，排除传感器故障。"

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。

    "3.  bedroom_occupancy（卧室运动传感器）在 09:22, 09:52, 10:22, 10:52 显示为 0，结合之前的温度数据波动和卫生间的高频使用，暗示住户可能在卧室休息/起床后前往卫生间，或者住户主要在卫生间和卧室之间活动，而客厅保持空闲，这符合单人居住或小家庭早晨的生活习惯。",
    "4.  living_room_light_1（客厅主灯）仅在 10:07 开启一次，随后在 18:15 再次开启，并在 21:49 关闭。白天的短暂开灯可能是为了采光或查看情况，晚上的开灯和关灯时间符合常规的晚间作息。没有发现深夜无故亮灯或长时间无人却亮灯的异常情况。",

  "threat_description": "客厅温度传感器读数严重偏离物理常识，显示异常高温（约 254°C），且与卧室、厨房温差巨大，表明传感器故障或数据漂移。",
  "reasoning": [
    "推理步骤 1: 分析日志中的温度数据，发现 living_room_temp_sensor 的 MeasuredValue 长期维持在 2530-2560 之间。在 Matter 协议及常见智能家居设备中，温度单位通常为摄氏度 (°C) 或开尔文 (K)。若单位为 °C，254°C 远超室内环境极限，甚至接近金属熔点；若单位为 K，则对应 -19°C 左右，但在夏季（8 月）且空调未开启时，室内不可能低至 -19°C。",
    "推理步骤 2: 对比同一时间段内其他房间的温度数据。bedroom_temp_sensor 和 kitchen_temp_sensor 的读数在 2437-2558 之间波动。虽然数值量级相似，但考虑到卧室通常比客厅凉爽，而厨房因烹饪可能较热，两者差异应在合理范围内（如 5-10°C）。然而，客厅读数始终显著高于卧室（例如 09:15 时客厅 2556 vs 卧室 2437，差值 119 个单位），这种巨大的温差不符合热力学规律，除非发生极端火灾，但烟雾报警器和 occupancy 传感器并未触发相应警报。",
    "推理步骤 3: 结合时间线判断。该异常持续数小时（08:25 至 11:45），期间住户有活动（bathroom_occupancy 多次为 1，living_room_light_1 开启），但温度读数毫无逻辑变化趋势（忽高忽低但绝对值极高）。这排除了真实的高温热源（如火灾），极大概率是传感器硬件故障、校准错误导致的数据漂移，或是固件将温度值错误地放大了倍数（例如实际 25.4°C 被报告为 2540 或 254）。",
    "结论：传感器提供的关键环境数据完全不可信，属于典型的 sensor_drift 或 sensor_malfunction，可能导致基于此数据的自动化场景（如空调控制）失效或误判。"

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
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。

    "2. 烹饪安全性检查：虽然厨房灶具 (kitchen_cook_surface) 在早晨被开启，但持续时间极短（例如 07-17 仅持续约 1 分钟），且伴随正常的温度传感器读数波动，未见烟雾报警器触发或长时间无人看管的情况，排除火灾或未关火风险。",
    "3. 门锁与入侵检测：入户门仅在早晨外出和晚间回家时由手动解锁/上锁，无异常时间段的开门记录，也无非法闯入迹象。",
    "4. 健康与安全状态：运动传感器在夜间（如 00:00-05:00）均显示无人（Occupancy=0），表明老人处于睡眠状态，无跌倒或夜间异常活动迹象。"
