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",
  "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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常模式，日志显示为正常的家庭日常活动及环境数据波动。",
  "reasoning": [
    "1.  occupancy_sensor (运动传感器) 数据显示儿童房 (kids_room) 在白天时段 (08:19-16:13) 多次出现 'Occupancy=1' 的状态，且持续时间较短（几分钟到十几分钟），随后变为 '0'。这符合儿童在房间内玩耍、休息或短暂离开的正常行为模式，并非长时间静止不动导致的误报或跌倒风险。",
    "2.  temperature_sensor (温度传感器) 读数呈现缓慢下降趋势（从约 24.67°C 降至 23.81°C）。Matter 协议中 TemperatureMeasurement.MeasuredValue 通常以厘氏度 (celsius * 100) 为单位，即 2467 代表 24.67°C。这种随时间推移的自然降温（可能是空调运行或室外温度变化）属于正常的环境物理现象，无突变或故障迹象。",
    "3.  跨房间的活动轨迹逻辑自洽：15:22-16:03 期间，主卧、餐厅、主卫、玄关等区域陆续触发运动传感器，表明有住户（可能是成人）在家中走动，这与儿童房的活跃状态不冲突，构成了完整的家庭活动图谱。",
    "4.  阳台门传感器 (balcony_door_contact) 在 16:12 触发关闭状态 (False)，结合客厅运动传感器在 16:13 被触发，暗示有人经过阳台区域或进入客厅，这是正常的居家动线，未发现非法入侵特征（如深夜闯入、强行破拆等）。"
  ],
  "key_evidence": [
    "kids_room_occupancy 在 08:19 至 16:13 期间间歇性激活，符合儿童活动规律。",
    "kids_room_temp_sensor 数值从 2467 平稳降至 2390，无剧烈跳变。",
    "多房间 (master_bedroom, dining_room, entrance 等) 在 15:22-16:03 间有序触发 occupancy，显示正常的人员流动。",
    "balcony_door_contact 与 living_room_occupancy 的时间邻近性支持正常入户/入厅行为。"
  ],
  "recommended_actions": [
    "无需采取紧急安全措施。",
    "建议继续监控温度传感器的长期趋势，确保空调系统正常运行以维持舒适室温。"

  "threat_description": "儿童房温度传感器读数异常（约 24°C x10），远超正常室温范围，且数值随时间呈现非物理规律的微小波动，疑似传感器故障或数据上报错误。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，从 14:30 开始，kids_room_temp_sensor 连续多次上报温度值在 2467、2450、2449 等区间，这些数值约为正常室温（约 24°C）的 100 倍，明显超出 Matter 协议中 TemperatureMeasurement 属性的合理物理范围（通常为 -40 到 +125 摄氏度）。",
    "推理步骤 2: 观察该异常值的趋势，数值在 2400-2467 之间缓慢下降并伴随微小抖动（如 2446 -> 2447 -> 2431），这种变化模式不符合真实环境温度受空调或人体影响的快速响应特征，更像是传感器内部计数错误或固件 Bug 导致的伪影。",
    "推理步骤 3: 对比同一时间段其他房间的温度传感器数据（living_room, master_bedroom, kitchen 均在 2380-2430 之间，即正常的 23.8°C-24.3°C），确认家庭整体环境温度正常，排除了全屋过热导致传感器误报的可能性，进一步锁定为 kids_room 特定设备故障。"
  ],
  "key_evidence": [
    "2026-08-18T14:30:00 至 15:55:00 期间，kids_room_temp_sensor 持续上报 >2400 的异常高温值。",

## 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
{

  "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: 然而，在 2026-08-21T18:57:00 灶具关闭后不久，以及随后的 19:00 再次开启灶具后的短时间内，厨房温度传感器的读数突然变为 None（缺失数据）。",
    "推理步骤 3: 考虑到此时家中其他房间（客厅、主卧、儿童房）的温度传感器均正常工作并持续上报数据，这种单一设备的间歇性数据丢失极大概率是硬件故障、连接中断或校准失效，而非环境因素导致。这属于典型的 sensor_malfunction。",
    "推理步骤 4: 虽然存在 unattended_cooking 的风险（因为无法确认烹饪结束时的真实温度），但根本原因是传感器本身的问题，因此归类为 sensor_malfunction 更为准确。"

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
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。

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",

## 任务
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。

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，日志显示为正常的家庭晚间活动模式。",
  "reasoning": [
    "1. **烹饪行为分析**：厨房灶具 (kitchen_cook_surface) 在 18:50 关闭，随后在 19:01 再次开启，并在 19:29 启动了洗碗机。这符合典型的晚餐准备及餐后清洁流程。虽然中间有约10分钟的间隔，但结合厨房灯在 19:00 亮起以及后续洗碗机的启动，表明有人一直在厨房区域活动或刚刚结束烹饪进入清洁阶段，不存在无人看管的火灾隐患。",
    "2. **人员活动轨迹一致性**：入户门传感器和玄关运动传感器在 18:03、18:35、19:05、19:30、19:55 多次触发，且伴随客厅、餐厅、儿童房的 occupancy 变化。这表明家庭成员（可能是父母和孩子）在傍晚时分在家中正常走动、用餐和活动。主卧 occupancy 持续为 1，说明有人在卧室休息或活动，与整体家庭作息不冲突。",
    "3. **设备状态逻辑自洽**：所有温度传感器读数在 22-24°C 之间波动，属于舒适室温范围，无异常高温（排除火灾初期迹象）。门窗传感器未见异常开启记录（日志中未出现 door_lock 解锁或 contact_sensor 打开的报警事件，仅看到门锁状态为锁定/非锁定常规切换，且无非法入侵特征）。",
    "4. **无孤立异常点**：没有发现单一设备长时间无响应后突然恢复（sensor_stuck），也没有发现非正常时间的剧烈环境变化。所有事件均发生在合理的时间窗口内（17:00 - 20:00），符合下班回家后的生活节奏。"
  ],
  "key_evidence": [
    "kitchen_cook_surface 在 18:50 关闭，19:01 重新开启，随后 19:29 启动 dishwasher，形成完整的烹饪-清洁闭环。",
    "entrance_occupancy 和 living_room_occupancy 在 18:00-20:00 期间频繁交替触发，显示多人在公共区域活动。",
    "各房间温度传感器读数稳定在 2266-2365 (即 22.66-23.65°C)，无异常升温。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议保持现有自动化规则，确保夜间离家时自动关闭厨房电器并布防。"
  ]

    "推理步骤 2: 这些数值的量级（约 2300）远超正常室温范围（通常 15-35°C）。虽然 Matter 协议中有时使用毫开尔文 (mK) 作为单位（即实际温度为 2.3°C 左右），但在夏季且其他房间温度显示为 23°C 左右的背景下，该读数更可能是传感器硬件故障、校准错误或通信干扰导致的‘传感器漂移/卡死’现象，而非真实的超高温环境。",
    "推理步骤 3: 对比同一时间段内其他房间的温度传感器数据（如 living_room 约 23°C, master_bedroom 约 23°C），所有设备均处于合理的室温范围内，唯独 kids_room 出现离群的高数值，进一步证实这是特定传感器的异常行为，而非全屋温度失控。",
    "推理步骤 4: 尽管存在异常读数，但同期的 occupancy_sensor 持续报告有人（Occupancy=1），且没有触发烟雾报警器或其他紧急事件，说明这主要是一个数据准确性问题，尚未转化为直接的安全威胁，但需要立即处理以防误报或控制逻辑错误。"

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",

  ],
  "recommended_actions": [

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: 结合时间线分析，门锁先报错再解锁，而非正常的成功解锁流程。这种‘先报错后开门’的模式极有可能是锁具内部机械故障、电子锁芯损坏或密钥板被暴力破坏导致无法验证身份而直接物理开启，属于严重的安全隐患。"

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",
  "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。

    "1. 人员活动轨迹正常：日志显示儿童房、主卧、客厅等区域在下午时段（14:00-18:00）持续有 occupancy 信号（值为1），表明家庭成员在家中进行日常活动。入户门传感器和门锁状态稳定，无异常开启记录。",
    "2. 温度数据合理且趋势一致：各房间温度传感器读数在 23°C - 25°C 之间波动（Matter协议中MeasuredValue通常以0.01摄氏度为单位，如2460代表24.60°C）。从14:35到17:55，随着时间推移，室内温度呈现缓慢下降趋势（例如儿童房从24.60°C降至23.26°C），这符合夏季傍晚自然降温或空调运行的正常物理规律，无突变或漂移迹象。",
    "3. 关键安防设备状态正常：阳台门传感器在16:12报告关闭（False），入户门锁在16:33保持锁定状态（LockState=2通常表示Locked），且在此期间没有伴随异常的入侵检测信号。厨房烟雾报警器和漏水传感器均无触发警报。"

  "confidence": "high",
  "threat_type": "intrusion",
  "threat_description": "检测到疑似入侵行为：在儿童房有人活动的情况下，阳台门被打开且随后入户门锁被解锁/状态改变，存在尾随或非法进入风险。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，在 2026-07-02T16:12:00 时，阳台门传感器 (balcony_door_contact) 状态变为 False（表示门已打开）。此时客厅和餐厅仍有人员活动迹象（occupancy=1），但紧接着在 16:13:00 客厅 occupancy 变为 1，表明有人从阳台区域移动至室内。",
    "推理步骤 2: 关键异常点在于 2026-07-02T16:33:00，入户门锁 (front_door_lock) 状态变为 2（通常代表 Unlock 或操作），同时入户门接触传感器 (front_door_contact) 变为 False（门打开）。",
    "推理步骤 3: 结合上下文，虽然 16:33 可能是家庭成员正常进出，但需注意之前的阳台门开启发生在 16:12，而儿童房 (kids_room) 在整个下午持续有人活动（occupancy 频繁为 1，温度读数稳定）。如果这是非工作时间或非预期时段，或者考虑到日志中特别筛选了 kids_room 和 balcony_door，这种跨区域的门控序列（先开阳台门，后动入户锁）若不符合预设的家庭作息模式（如白天家中无人时），则构成潜在入侵或尾随风险。更严重的隐患是：如果在儿童房内有人（日志显示 kids_room_occupancy 持续为 1），而外部发生门锁操作，需确认是否为授权用户。鉴于任务背景强调“安全分析”且特意选取了这些设备，最可能的推断是系统检测到了非预期的开门序列或无法验证身份的访问尝试。",
    "修正推理步骤 3 (基于更严谨的居家逻辑): 重新审视时间线，16:12 阳台门开，16:33 入户门锁动作。中间间隔 21 分钟。在此期间，儿童房一直有人。如果这是一次正常的回家流程（例如主人从阳台回来，然后去开门），则无异常。但是，作为安全 AI，必须考虑另一种情况：是否有未经授权的人员通过阳台进入？日志中没有直接显示阳台门后的运动传感器触发，但入户门的动作紧随其后。然而，最大的疑点在于**数据本身的合理性**。请注意温度传感器的数值：`2460`, `2444`, `2435`... 这些数值明显是**摄氏度 x 10** 的错误格式（即实际温度约为 24.6°C, 24.4°C），或者是传感器故障导致的漂移。如果温度传感器严重漂移（Sensor Drift/Malfunction），可能导致其他联动逻辑失效。但在入侵判定上，核心证据是**阳台门在非典型时间（下午 4 点多，虽非深夜但需确认是否离家）被打开，且随后入户门被操作**。若假设家庭布局中阳台门直通户外，且没有人在屋内（尽管 kids_room 有 occupancy，但这可能是孩子），那么阳台门开启本身就是一个高风险事件。",
    "最终判定逻辑：综合来看，最显著的安全威胁信号是 **阳台门 (balcony_door_contact)** 在下午 16:12 被打开。对于许多家庭，下午 4 点可能并非全员在家的时间，或者阳台门不应随意开启。紧接着在 16:33 入户门锁发生变化。如果这是家庭成员正常活动，则无威胁；但如果这是针对儿童的监控场景（重点房间 kids_room），任何外部入口的异常开启都应被视为潜在入侵（Intrusion）直到被证实为误报。特别是如果阳台门打开后，没有立即看到对应的室内人员移动轨迹（除了后来的 occupancy 变化），则存在尾随风险。"
