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",
  "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": "日志显示为正常的家庭晚间活动模式，包括人员回家、开灯、开启空调及烹饪准备，未发现安全威胁或设备异常。",
  "reasoning": [
    "1. **人员归家与活动逻辑一致**：17:21至18:04期间，玄关（entrance）、儿童房、主卧、餐厅的运动传感器依次触发，符合家庭成员陆续回家的行为模式。18:12入户门锁执行手动上锁操作，且门磁状态由False变为True（关闭），表明有人进入并锁门，随后客厅灯光和空调开启，符合下班回家的正常流程。",
    "2. **烹饪行为正常**：18:11厨房灯亮起，18:12灶具开启，这是典型的晚餐准备场景。虽然日志中未直接显示烟雾报警器报警或漏水传感器触发，但结合时间点和后续无紧急事件，属于正常生活行为。",
    "3. **温度数据解读合理**：温度传感器数值（如2387, 2377等）在Matter协议中通常表示摄氏度乘以100的值（即23.87°C）。数据显示室内温度维持在舒适的23-24°C左右，且随着空调开启（18:12）和人员活动，温度有细微波动，符合物理规律，无传感器漂移或故障迹象。",
    "4. **无异常入侵迹象**：所有门窗传感器仅在特定时间点（如早晨7:50可能为出门，傍晚18:12为关门）变化，且伴随内部运动传感器的活跃，排除了非法入侵的可能性。"
  ],
  "key_evidence": [
    "18:12 front_door_lock | Event: LockOperation(LockOperationType=1, OperationSource=Manual) - 确认有人手动锁门",
    "18:12 living_room_light_1 | OnOff.OnOff = True 及 living_room_ac | OnOff.OnOff = True - 回家后开启照明和空调",
    "18:11 kitchen_light | OnOff.OnOff = True 及 18:12 kitchen_cook_surface | OnOff.OnOff = True - 开始烹饪",
    "17:21-18:04 多个房间 occupancy_sensor 依次触发 - 符合多人归家的时间序列"
  ],
  "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，确保夜间安防监控处于激活状态。"
  ]
}
```

{
  "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": [
    "正常样本回家后有客厅/厨房过渡活动；异常样本直接进入卧室。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"

## 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",
  "threat_description": "一句话描述发现的问题或确认安全",
  "reasoning": [
    "推理步骤1: ...",

    "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行为，设备日志显示独居老人的日常活动规律且正常。",
  "reasoning": [
    "1. 活动模式分析：日志显示老人在早晨（06:30-09:00）起床，随后在客厅、厨房、卧室之间活动，符合正常的晨间作息。下午和傍晚也有持续的活动记录（如17:00后厨房亮灯、客厅有人），表明老人全天处于活跃状态，无长时间静止或失联迹象，排除了跌倒或突发健康事件导致的无响应风险。",
    "2. 关键设备状态检查：虽然8月27日11:31厨房温度传感器返回'None'，但紧接着11:55恢复了读数，且此前灶具已关闭（11:30 Off），这更可能是传感器短暂通信故障或数据上报延迟，而非火灾或设备故障引发的连锁反应，因为烟雾报警器在此期间未触发报警。",
    "3. 环境与安全指标：所有温度读数均在合理范围内（约21-25摄氏度），未见极端高温提示火灾风险。门窗传感器仅在早晨有一次关闭记录（08:25），其余时间多为常态监测，未发现非法入侵迹象（如深夜门锁开启或窗户异常打开）。",
    "4. 逻辑一致性：运动传感器与灯光控制逻辑一致（如17:01厨房灯亮，伴随后续厨房/客厅活动），未发现设备卡死或误报导致的异常频繁开关。整体行为轨迹连贯，符合独居老人的生活规律。"
  ],
  "key_evidence": [
    "全天多房间运动传感器（living_room, kitchen, bedroom, entrance）持续有Occupancy=1的记录，证明人员活动正常。",
    "厨房灶具在11:30关闭，之后虽有温度传感器短暂丢失数据，但随即恢复且无烟雾报警，排除烹饪安全隐患。",
    "温度传感器数值稳定在舒适区间（2100-2550对应21-25.5°C），无异常波动。",
    "门锁及窗户传感器仅在早晨出现一次状态变化，无夜间或非授权时段的异常开启记录。"
  ],
  "recommended_actions": [
    "无需立即采取安全措施。",
    "建议定期检查厨房温度传感器的连接稳定性，以确保持续的数据可靠性。",
    "维持当前的监控策略，关注老人日常活动模式的任何显著偏离。"
  ]
}
```

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器在灶具关闭后出现数据丢失（None），且后续读数异常偏低，疑似传感器故障或通信中断，存在安全隐患。",
  "reasoning": [
    "推理步骤 1: 在 2026-08-27T11:30:00，日志显示厨房灶具 (kitchen_cook_surface) 状态变为 False (关闭)，但在随后的 11:31:00，厨房温度传感器 (kitchen_temp_sensor) 报告 MeasuredValue 为 None。对于正在监测火灾风险的老人家庭，关键安全传感器的突然失效是严重异常。",
    "推理步骤 2: 虽然之后传感器恢复了数值，但在 2026-08-28 的傍晚时段（17:55 - 19:10），当厨房有人活动且灯光开启时，温度读数从正常的 2300+ (约 23°C) 骤降至 2294-2295 (约 22.9°C)，随后又波动。考虑到之前出现过数据丢失，这种不稳定的低值可能意味着传感器校准漂移、硬件损坏或连接不稳定，无法准确反映真实环境温度以触发必要的报警。",
    "推理步骤 3: 结合独居老人的背景，厨房是火灾高发区。如果温度传感器因故障未能检测到异常高温（如油锅起火初期），将导致烟雾报警器延迟响应或完全漏报，构成重大安全风险。"
  ],
  "key_evidence": [
    "2026-08-27T11:31:00 kitchen_temp_sensor 报告 MeasuredValue = None (数据丢失)",
    "2026-08-28T18:55:00 至 19:10:00 期间，厨房温度读数异常偏低且波动 (2294-2295)，与正常室温趋势不符"

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

    "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行为，所有日志记录符合正常的家庭日常生活模式。",
  "reasoning": [
    "1. **活动规律性分析**：跨天摘要显示，客厅（living_room）的活动计数稳定在112-115次左右，而卧室、玄关等区域的活动计数较高（200+），这符合典型的“公共区域低频使用，私人/高频活动区域高频使用”的家庭居住特征。没有发现突发的、非典型的时间段活动激增。",
    "2. **人员流动逻辑正常**：7月30日傍晚17:53，入户门锁被手动打开（LockOperation=1通常指解锁），随后玄关运动传感器检测到有人进入（Occupancy=1）。紧接着餐厅、儿童房、主卫等区域陆续出现人员活动信号，且时间间隔合理（几分钟内分散到不同房间），符合家庭成员下班回家后的正常动线。",
    "3. **设备状态与环境影响一致**：温度传感器读数随时间变化呈现自然趋势（如早晨升温，傍晚降温），数值在合理范围内（22°C-26°C左右，Matter协议中MeasuredValue通常为十分之一摄氏度，即2486代表24.86°C）。厨房灯在夜间开启（18:40）也符合生活常识。",
    "4. **无危险迹象**：未检测到烟雾报警器触发、漏水传感器报警、门窗异常长时间开启或锁具故障等高危事件。厨房灶具和洗碗机虽在设备列表中，但日志中未出现异常持续运行或无人看管下的危险操作信号。"
  ],
  "key_evidence": [

  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",
    "可考虑优化自动化规则，例如根据入户门解锁自动开启玄关灯，提升便利性。"

  "reasoning": [
    "推理步骤 1: 分析日志发现，在 2026-07-30T18:40:00 时，厨房温度传感器报告了 'MeasuredValue = None'。这通常表示传感器未发送有效读数、通信超时或硬件故障。",
    "推理步骤 2: 结合上下文，该时间点前后（18:05 - 19:15）厨房温度传感器频繁上报读数（约 2300K-2289K，即 27°C-25°C 左右，符合夏季室内环境），且厨房灯被开启，表明厨房处于有人使用或活跃状态。在此关键安全区域发生数据断连属于高风险事件。",
    "推理步骤 3: 对比其他房间，温度传感器工作正常（如主卧、客厅均有连续稳定的读数）。单一传感器的突然失效排除了全屋网络瘫痪的可能性，指向该特定设备（kitchen_temp_sensor）存在 sensor_malfunction（传感器故障）或严重的 sensor_drift（漂移/卡死导致无法上报）。考虑到是返回 None 而非固定错误值，更倾向于通信中断或硬件死机。"

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：

  "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。

  "reasoning": [
    "推理步骤 1: 在 2026-08-17T18:54:30，厨房灶具 (cook_surface) 被开启，随后在 18:55:00 厨房温度传感器读数从正常的约 25°C 跳变为 2572 (即 25.72°C)，虽然数值本身未达报警阈值，但紧接着在 19:00 至 19:20 期间，读数异常地维持在 2400-2500 区间，而客厅和卧室温度正常下降，显示传感器可能受干扰或故障。",
    "推理步骤 2: 最关键的异常发生在 18:20 至 18:40 之间。此时灶具尚未开启，但厨房温度传感器读数却从 2349 急剧上升至 2709 (27.09°C)，并在 18:30 达到峰值 2707。这一升温趋势与当时无人员在场（occupancy=0）且无热源开启的状态完全不符，表明传感器存在严重的漂移或校准错误。",
    "推理步骤 3: 结合 Matter 协议标准，温度传感器通常以 0.01°C 为单位上报。读数如 2709 代表 27.09°C。考虑到夏季傍晚室内温度通常在 23-25°C 左右，短时间内无源升温至 27°C+ 极不自然。这种‘幽灵升温’现象会导致系统误判环境温度过高而关闭空调，或者更危险的是，当真实火灾发生时，传感器可能因之前的漂移而失效或给出错误读数，构成潜在的安全隐患。"

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",

  ],
  "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。

```json

    "2. **环境控制逻辑**：住户回家后（17:53），立即开启了客厅灯和空调（SystemMode=3 通常为制冷或制热，结合温度下降趋势看可能是制冷或刚启动），这是典型的回家舒适化操作，无异常。",
    "3. **烹饪活动验证**：18:24 厨房灯亮起，18:29 灶具开启。这发生在傍晚时段（18:30左右），符合家庭准备晚餐的习惯。虽然灶具开启后未见明显的烟雾报警器触发或长时间无人看管（日志截止于18:43，仅过去14分钟，属于正常烹饪初期），且厨房温度传感器读数稳定（2300-2312范围，无急剧升温报警），因此不构成火灾或未看管烹饪风险。",

## 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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁，日志显示为独居老人在傍晚至夜间时段的正常居家活动及环境数据记录。",
  "reasoning": [
    "1. **人员活动模式分析**：日志显示从17:03开始，客厅、卧室、厨房、玄关等多个区域频繁出现运动传感器触发（Occupancy=1），且伴随灯光开启/关闭（如19:00客厅灯亮，20:53卧室灯闪后灭）。这种多房间、持续性的活动轨迹符合老人在家中进行日常起居（如看电视、准备晚餐、洗漱、休息）的行为特征，无长时间静止或异常滞留迹象。",
    "2. **门锁状态分析**：20:53发生的入户门锁定事件（LockOperation Type=0 Manual Lock）发生在老人已在屋内活动数小时后，属于正常的睡前或离家前锁门行为，并非非法入侵或尾随进入。",
    "3. **环境与安全设备状态**：全时段内烟雾报警器、一氧化碳报警器、漏水传感器均无报警触发记录。温度传感器读数在合理范围内波动（约21-23°C），未见极端高温（火灾风险）或低温异常。",
    "4. **设备逻辑一致性**：虽然部分时间戳存在秒级差异（如20:53的多个事件），但这通常由不同设备时钟同步延迟或网络传输抖动引起，结合上下文（先开灯后关灯，随后锁门），逻辑上是连贯的睡前准备流程，非设备故障。"
  ],
  "key_evidence": [
    "17:03 - 20:53 期间，living_room, bedroom, kitchen, entrance 等多区域 occupancy_sensor 持续触发，表明有人在家活动。",
    "20:53:06 front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Manual)，确认为手动上锁，且此时段室内有活动，属正常行为。",
    "全程无 smoke_co_alarm 或 water_leak_detector 报警信号。",
    "temperature_sensor 读数稳定在 2100-2330 (21-23.3°C) 之间，无异常高温。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议定期校准各房间温度传感器以确保读数准确，并检查运动传感器的灵敏度设置是否适应老人的行动速度。"
