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: ..."
  ],

    "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，所有设备活动符合正常的家庭晚间生活模式。",
  "reasoning": [
    "1. **人员活动轨迹正常**：日志显示家庭成员在傍晚至夜间（18:00-22:00）在各个房间（客厅、餐厅、主卧、儿童房、玄关）之间有序移动。例如，18:09 客厅有人，随后 18:13 主卧有人，18:15 餐厅有人，这符合一家人回家或在家活动的典型场景。",
    "2. **烹饪行为合规**：厨房灶具 (kitchen_cook_surface) 在 18:18:30 开启，并在 19:30:00 关闭，持续约 1 小时 11 分钟。这是典型的晚餐准备时间，且结束后及时关闭，未发现无人看管或长时间未关闭的异常风险。",
    "3. **照明与温控逻辑一致**：客厅主灯在 19:00 开启，21:30 关闭，符合晚间活动及就寝前的习惯。温度传感器读数在 2243-2359 (即 22.4°C - 23.6°C) 之间波动，属于舒适的室内环境温度，空调在 18:09 设置为制冷模式(3)，随后温度逐渐下降并稳定，表明系统运行正常。",
    "4. **无入侵迹象**：入户门传感器和门锁状态未在日志中显示异常的频繁开关或非法解锁尝试。运动传感器仅在有人时触发，无鬼影或误报导致的持续占用。"
  ],
  "key_evidence": [
    "kitchen_cook_surface OnOff=True at 18:18:30 and Off at 19:30:00 (正常烹饪时长)",
    "living_room_light_1 OnOff=True at 19:00:00 and Off at 21:30:00 (正常晚间照明)",
    "Multiple occupancy sensors triggering in different rooms sequentially (18:09 living_room -> 18:13 master_bedroom -> 18:15 dining_room) indicating normal family movement",
    "Temperature values stable between 22.4C and 23.6C with AC running"
  ],
  "recommended_actions": [
    "无需采取任何行动，当前环境安全。",
    "建议继续保持当前的自动化规则，如离家自动关灯/关空调等，以优化能源使用。"
  ]
}
```

{
  "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。"

## 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。

```json

    "2. 关键设备逻辑一致性：重点关注的 kitchen_light 在三天早晨均于 07:00-07:10 左右开启，且伴随厨房温度传感器读数上升（如 07:15-07:25 期间），暗示可能进行了早餐准备或烧水等常规操作，无长时间无人看管烹饪迹象。living_room_occupancy 在白天大部分时间为 0（离家），晚间为 1（在家），状态切换合理。",
    "3. 环境数据合理性：温度传感器读数随时间呈现自然的昼夜波动（白天较高，夜间/清晨较低），且数值在合理范围内（约 22-25°C 对应 Matter 协议的 scaled value），未发现传感器卡死（数值不变）或漂移（数值突变）的迹象。",
    "4. 安全设备状态：入户门锁在离家时锁定（LockState=1），回家时解锁（LockState=2），无非法入侵尝试记录。烟雾报警器和漏水传感器在日志片段中未触发告警。"

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。

```json

  "reasoning": [
    "1. **入户门状态分析**：日志中 `front_door_contact` 在 18:20 变为 False（关闭），且没有伴随 `door_lock` 的异常解锁记录或入侵报警。结合后续厨房和客厅的活动，这符合住户回家关门的行为逻辑，而非非法入侵。",
    "2. **烹饪行为分析**：`kitchen_cook_surface` 在 18:00:30 开启，并在 18:36:00 关闭，持续时间约 35 分钟。随后立即启动了洗碗机 (`kitchen_dishwasher`)。这是一个非常典型的“做饭-清理”连贯行为序列，不存在无人看管导致火灾的风险（unattended_cooking）。",
    "3. **人员活动轨迹**：运动传感器 (`occupancy_sensor`) 在客厅、卧室频繁触发，且在卫生间有短暂的进出记录（17:31, 18:19, 18:31, 19:01 均为离开/无占用状态，暗示之前有人使用）。这种多房间、高频次的活动模式符合正常住户在傍晚时段的居家生活节奏。",
    "4. **环境数据稳定性**：温度传感器读数随时间缓慢变化，符合室内热惯性特征，无突变或设备故障迹象。"
  ],
  "key_evidence": [
    "kitchen_cook_surface 开启后 35 分钟内关闭，紧接着启动 dishwasher，形成完整的烹饪清洁闭环。",
    "front_door_contact 在 18:20 关闭，与室内活动增加的时间点吻合，表现为归家行为。",
    "多个房间的 occupancy_sensor 持续活跃，证明屋内有人活动，排除了空屋入侵或长时间静止的健康风险。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议保持现有自动化规则，如烹饪结束后自动提醒检查灶具，以维持良好的安全习惯。"

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",

  ],
  "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 4: 虽然用户操作了厨房灯和空调，但无法解释为何仅厨房传感器失效而其他区域正常。若为烹饪导致的升温，温度应缓慢上升且不会超过 270°C，也不会出现数据中断。因此判定为传感器故障 (sensor_malfunction/sensor_drift)。"

    "同期其他房间（客厅、卧室）温度传感器读数稳定在 2293-2350 mK (约 23-24°C)，证实环境整体温度正常。",

## 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",

    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",

}
```

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. 厨房安全无异常：18:25 灶具关闭，随后洗碗机启动（18:25:14），这是典型的晚餐后清洁流程。虽然日志中 kitchen_temp_sensor 在18:26出现一次 None 值，但随后立即恢复正常读数且温度呈自然下降趋势（从2309降至2244等），排除传感器故障或火灾风险。",
    "3. 卧室无人确认：主卧和次卧的 occupancy_sensor 在晚间时段持续报告为 0，且温度随时间缓慢下降（如主卧从2310降至2242），符合无人居住时的自然散热规律，未发现异常入侵或长时间静止的健康风险。",
    "4. 卫生间活动正常：卫生间 occupancy_sensor 在多个时间点（18:32, 19:02, 19:32, 20:32, 21:02, 21:32, 22:02）均报告为 0，表明卫生间未被占用，无跌倒或被困迹象。"

    "master_bedroom_occupancy 和 second_bedroom_occupancy 在 18:00-22:00 期间持续为 0，且对应房间温度自然下降。",
    "bathroom_occupancy 在整段日志期间始终为 0，无异常滞留。"
  ],

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": 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. 人员活动符合常规作息：日志时间跨度为17:20至22:10，属于典型的傍晚至睡前时段。多个房间（客厅、餐厅、儿童房、主卧）的运动传感器频繁触发（Occupancy=1），且伴随灯光开启（如19:00客厅灯亮）和空调调节，表明家庭成员在正常居家活动。",
    "2. 设备状态逻辑一致：客厅温度从23.5°C逐渐下降至22.4°C左右，同时空调被设置为制冷模式（SystemMode=3），这符合夏季晚间降温的正常行为。厨房窗户关闭（Contact=False）与室内温度稳定相符，无异常开启迹象。",
    "3. 无入侵或异常特征：入户门传感器仅在玄关运动传感器触发时偶有联动记录（可能是误报或家人进出），但未出现门锁异常解锁、非法闯入或深夜无人时的异常活动。所有事件均在合理的时间窗口内发生，没有长时间静止后的突然活跃等可疑模式。"
  ],
  "key_evidence": [
    "18:06-22:10期间，living_room_occupancy, kids_room_occupancy, master_bedroom_occupancy等多处传感器持续报告有人存在（Value=1）。",
    "18:06 living_room_ac Thermostat.SystemMode = 3 (制冷)，配合温度从23.51降至22.46，符合主动降温行为。",
    "19:00 living_room_light_1 OnOff=True，随后21:30 Off，符合晚间照明使用习惯。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续监控夜间（23:00后）的异常活动，确保睡眠期间无未授权进入。"
  ]
}
```

{
  "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": [
    "正常样本只是晚间一次开关灯；异常样本短时间内重复高频操作。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
