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
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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",

  ],
  "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。

    "推理步骤 3: 虽然之后传感器恢复了数值，但后续读数（如 2294, 2291 等）与之前及客厅温度的趋势相比出现了不自然的微小震荡和恢复延迟，且无法排除传感器因刚才的故障而处于不稳定状态的风险。考虑到厨房涉及烹饪和电器使用，温度监测失效属于关键安全功能缺失。"

    "3. 分析安防状态：22:30:25 入户门传感器触发（True，通常表示门被打开或处于非闭合状态），紧接着 22:30:26 门锁执行手动锁定操作（LockState = 1）。这表明住户可能刚回家锁门，或者在室内检查并确认门锁已锁好。结合后续长时间无异常入侵迹象，且所有动作连贯，判定为正常用户行为。"

## 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。

    "2. 门锁状态分析：22:37左右，入户门传感器显示开启（True），随即门锁执行了手动上锁操作（LockState=1）。结合前后无其他异常入侵迹象，且发生在深夜归家或检查门窗的常规场景，判定为住户正常锁门行为，非非法入侵。",
    "3. 设备联动与人员轨迹：客厅灯光和空调在22:37关闭，同时主卧窗帘完全闭合（CurrentPositionLiftPercent100ths=10000表示全开/全关取决于具体实现，但结合关灯动作通常意味着就寝准备），表明住户正在结束客厅活动并进入卧室休息。运动传感器在多个房间（餐厅、儿童房、玄关、客厅）持续触发，随后主卧传感器活跃，符合从公共区域向私密休息区转移的正常人体移动轨迹。",
    "4. 排除其他风险：厨房灶具、烟雾报警器、漏水传感器均无异常触发；无长时间无人值守烹饪或火灾/泄漏迹象；无跌倒或健康紧急情况的体征数据。"

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。

根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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. 安防状态一致：入户门锁在22:52锁定（LockState=1），此时客厅运动传感器最后活跃不久，且之后无其他人员进入迹象，表明住户已就寝并锁门，符合安全习惯。",
    "4. 传感器数据稳定：温度读数随时间缓慢下降（从~23.3°C降至~22.6°C左右），这是夏季夜晚环境温度自然变化的趋势，无突变或异常停滞，排除传感器故障。"

## 任务
请从下面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: ..."
  ],
  "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": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常模式，日志显示为正常的夜间居家活动及环境监控数据。",
  "reasoning": [
    "1. 门锁状态分析：22:31:20 入户门传感器显示开启（True），随即在 22:31:21 触发手动上锁操作（LockOperation Type=0）并确认为锁定状态（LockState=1）。这一系列动作符合住户回家进门后反锁门的正常行为逻辑，且发生在晚间时段，无非法入侵迹象。",
    "2. 人员活动规律：运动传感器数据显示，主卧、客厅和玄关在 22:15 至 23:40 期间多次出现 occupancy=1 的状态，随后在 22:30、23:00、23:30 等整点时刻变为 occupancy=0。这种周期性的“有人-无人”切换符合住户在卧室休息、偶尔起身或在客厅活动的正常生活节奏，并非长时间静止不动导致的误报，也非异常的大范围移动。",
    "3. 设备与环境状态：温度传感器读数在 22.4°C - 22.7°C 之间波动，属于舒适的室内环境温度，无火灾或极端天气导致的温度骤变。所有灯光和空调在 22:31 左右关闭，与住户进入休息状态的行为一致。未发现烟雾报警、漏水或一氧化碳报警等危险信号。"
  ],
  "key_evidence": [
    "22:31:20 front_door_contact = True 紧接着 22:31:21 front_door_lock LockState = 1 (Manual Lock)，表明是住户主动关门落锁。",
    "22:31:01 living_room_light_1 OnOff = False 和 22:31:02 living_room_ac OnOff = False，配合后续运动传感器的间歇性消失，符合就寝前的关灯关空调习惯。",
    "Temperature readings remain stable between 2241 and 2272 (approx 22.4-22.7°C), indicating no thermal anomalies."
  ],
  "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，如离家/就寝自动关灯锁门。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "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": [
    "日志中未出现持续矛盾、直接告警或高风险时序链路。"

  "recommended_actions": [
    "建议立即检查并触发安全响应。"

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",

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. 人员活动模式分析：客厅和玄关的运动传感器在 21:59、22:19、22:39、22:59、23:19、23:39 等时间点频繁触发 Occupancy=1，间隔约为 20 分钟。这种规律性的短时活动可能表明住户在客厅区域走动、查看设备或进行日常活动。同时，卧室（主卧、次卧）的运动传感器在多个整点时刻报告 Occupancy=0，表明卧室无人，这与客厅有人活动的情况相符，符合典型的晚间起居行为模式。",
    "3. 环境与设备状态分析：温度传感器读数在 22.4°C - 22.7°C 之间波动，属于正常室内温度范围，且变化平缓，无剧烈跳变导致的传感器故障嫌疑。空调在 21:56 关闭，之后未见开启记录，结合温度稳定，说明室温适宜或已停止制冷/制热，无能源浪费或设备故障迹象。卫生间漏水传感器、烟雾报警器均无报警记录。"

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
请结合下面的 Matter 设备日志，判断是否存在设备健康问题，并说明可能的故障类型。

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: 日志中未出现持续矛盾、直接告警或高风险时序链路。"
  ],
  "key_evidence": [
    "日志中未出现持续矛盾、直接告警或高风险时序链路。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "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": [
    "日志中未出现持续矛盾、直接告警或高风险时序链路。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]
}
