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",

    "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。

    "推理步骤 1: 时间线分析显示，在 2026-07-05T16:10:00 时，儿童房 (kids_room) 运动传感器报告有人 (Occupancy=1)，但仅持续了约 4 分钟，随后在 16:14:00 变为无人状态。",
    "推理步骤 2: 关键异常发生在 16:14:00，此时阳台门接触传感器 (balcony_door_contact) 状态变为 False（表示门被打开），紧接着在 16:15:00 阳台灯 (balcony_light) 被点亮。这表明有人打开了阳台门并进入了阳台区域。",
    "推理步骤 3: 结合上下文，从 16:10 到 16:14 期间，所有主要房间（包括客厅、主卧、次卧）的运动传感器均报告为 0（无人）。这意味着进入阳台的人并非家庭成员正常回家或移动路径的一部分，极有可能是外部人员通过阳台门潜入室内，或者试图进入儿童房区域。",
    "推理步骤 4: 虽然 16:10 儿童房曾短暂检测到人，但这可能是入侵者试图接近该房间，或者是之前的误报/残留信号，但紧随其后的阳台门开启和灯光变化构成了明确的入侵尝试证据链。"
  ],

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: ...",

    "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": true,
  "confidence": "medium",
  "threat_type": "child_safety",
  "threat_description": "儿童活动从儿童房转移到阳台",
  "reasoning": [
    "推理步骤1: 儿童房活动后很快打开阳台门",
    "推理步骤2: 阳台灯被打开",
    "推理步骤3: 缺少明确陪同信号"
  ],
  "key_evidence": [
    "儿童房活动后很快打开阳台门",
    "阳台灯被打开",
    "缺少明确陪同信号"
  ],
  "recommended_actions": [
    "判定为儿童接近高处风险区域，建议立即干预。"
  ]
}

{
  "is_anomaly": true,
  "confidence": "low",
  "threat_type": "intrusion",
  "threat_description": "存在异常，但原因更可能属于其他类别。",
  "reasoning": [
    "推理步骤1: 日志里有异常，但我把它归因为另一类威胁。"
  ],
  "key_evidence": [
    "儿童房活动后很快打开阳台门"
  ],
  "recommended_actions": [
    "建议按该错误类别处理。"
  ]
}


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",

    "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。

    "推理步骤 2: 结合上下文环境分析，在 17:30、18:00 和 18:30 等多个时间点，所有房间（包括 living_room, dining_room, master_bedroom, kids_room 等）的运动传感器均报告 Occupancy = 0，表明此时家庭成员已离开房屋。",
    "推理步骤 3: 在住户离家后，门锁出现连续的操作错误是异常行为。这可能导致住户无法从内部正常反锁大门，或者外部人员利用此故障进行尾随进入（Tailgating），同时也可能意味着门锁电池电量不足或机械结构卡死，属于高优先级的安全威胁。"

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。

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。

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",

    "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。

  "threat_type": "lock_malfunction",
  "threat_description": "入户门锁在住户离家时段连续出现多次键盘操作错误，且伴随全屋人员离开迹象，存在被尝试入侵或设备故障导致无法安全锁门的风险。",
  "reasoning": [
    "推理步骤 1: 分析 occupancy 数据发现，从 17:30 开始，包括客厅、餐厅、主卧、次卧及儿童房在内的所有主要房间运动传感器均报告无人 (Occupancy=0)，表明住户已完全离开房屋。",
    "推理步骤 2: 在确认屋内无人的情况下，日志显示 front_door_lock 在 18:05 至 18:07 期间连续三次报告 'LockOperationError(source=Keypad)'。这种在短时间内针对同一输入源（键盘）的重复失败通常意味着有人正在尝试通过密码进入，或者用户因忘记密码/设备故障而反复尝试。",
    "推理步骤 3: 结合时间线，此时为傍晚 18:00 左右，通常是住户下班回家的高峰期。如果是正常行为，用户应能成功解锁；连续的报错更倾向于外部攻击者尝试猜测密码，或是门锁硬件/固件故障导致无法正常响应合法指令，构成了潜在的安全威胁。"

  "key_evidence": [
    "17:30 - 19:40 期间，kids_room_occupancy, living_room_occupancy, master_bedroom_occupancy 等多个关键区域持续报告 Occupancy = 0。",

## 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",
  "threat_description": "一句话描述发现的问题或确认安全",
  "reasoning": [

    "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。

  "threat_description": "儿童房温度传感器读数异常（约 2247-2261），数值远超正常室温范围，且伴随高频波动，疑似传感器故障或数据漂移。",
  "reasoning": [
    "推理步骤 1: 分析日志发现 kids_room_temp_sensor 在 21:20 至 23:20 期间持续报告温度值在 2247 到 2261 之间。",
    "推理步骤 2: 对比同一时间点的其他房间温度传感器（如 living_room 约 2242-2261，master_bedroom 约 2248-2264），虽然数值量级看似接近，但考虑到 Matter 协议中温度通常以 0.1°C 为单位，这些整数数值（如 2247）极有可能是 22.47°C 的误读或者是传感器固件将单位错误地映射为毫开尔文/分度值导致的巨大偏差，或者更可能是传感器完全损坏导致输出固定高位噪声。然而，结合上下文，最合理的解释是传感器读数逻辑错误（例如将 22.47 显示为 2247），因为如果是真实 2247°C，房屋早已烧毁且烟雾报警器会触发。另一种可能性是传感器校准严重失效。",
    "推理步骤 3: 尽管存在这种数值异常，但需确认是否构成直接安全威胁。日志显示该时段内 kids_room_occupancy 为 1（有人），且没有触发 smoke_co_alarm 或 water_leak_detector。如果这是真实的超高温，必然伴随火灾风险；如果是数据格式错误，则属于设备故障。鉴于没有火灾报警联动，且其他房间温度相对平稳，判定为 sensor_malfunction（传感器故障/数据漂移）而非 fire_risk。",
    "推理步骤 4: 综合判断，该异常数据点不符合物理规律（除非发生极端灾难性事件但未触发其他警报），因此归类为传感器本身的 malfunction 或 drift，需要人工干预验证。"
