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行为，日志显示为正常的家庭环境监控数据及晚间常规活动。",
  "reasoning": [
    "1.  occupancy传感器持续报告为0：从凌晨05:30到傍晚17:30，客厅、主卧、次卧、卫生间和玄关的运动传感器均持续显示Occupancy=0。这表明住户在此期间不在家（例如外出工作或上学），符合“两室一厅”家庭白天的典型生活模式，并非设备故障或人员滞留。",
    "2.  温度数据正常波动：客厅温度传感器在白天记录的温度值（约24.6°C - 25.4°C）呈现随时间缓慢上升后下降的趋势，且与其他房间（如卧室、厨房）的温度读数逻辑一致，无剧烈跳变或传感器卡死迹象。",
    "3.  晚间活动符合常理：18:30客厅灯开启，18:35厨房灯开启，这通常对应住户下班回家后的晚餐准备或休闲活动。此时段之前长时间无活动，与之前的离家状态衔接自然。",
    "4.  无其他危险信号：日志中未出现烟雾报警、漏水检测、门锁异常开启或灶具长时间无人看管等高风险事件。"
  ],
  "key_evidence": [
    "所有房间运动传感器在05:30-17:30期间持续为0，表明房屋空置。",

{

  "confidence": "high",
  "threat_type": "sensor_drift",
  "threat_description": "客厅温度传感器读数严重偏离物理现实，显示异常高温（25°C+），且与住户行为模式（无人居住）及后续正常数据存在巨大矛盾。",
  "reasoning": [
    "推理步骤 1: 分析时间窗口 05:30 至 08:40，日志显示 living_room_temp_sensor 的 MeasuredValue 持续在 2445 至 2545 之间波动。考虑到 Matter 协议中温度通常以 0.01°C 为单位，该数值对应 24.45°C 至 25.45°C。",
    "推理步骤 2: 结合上下文环境，此时段为清晨至上午，且 occupancy_sensor 多次报告 Occupancy = 0（无人）。虽然夏季室温可能较高，但连续数小时维持在 25°C 以上且无空调运行记录（日志中未见 air_conditioner 状态变化或设定值），对于有窗户和通风的两室一厅住宅而言，属于非典型的高温状态，尤其是考虑到傍晚 16:50 后温度骤降至 23.6°C 左右。",
    "推理步骤 3: 对比傍晚数据（16:50-17:40），温度稳定在 23.3°C - 23.7°C 区间，这与清晨的数据形成了巨大的、不合理的阶梯式差异。这种在同一室内环境下，短时间内出现如此剧烈的温差（超过 2°C 且持续数小时），而没有任何热源（如烹饪、人员聚集）或设备开启（空调未开）的记录，极大概率是传感器硬件故障、校准漂移或被恶意篡改，而非真实环境温度变化。",
    "推理步骤 4: 厨房温度传感器在同一时段也出现了类似的异常偏高趋势（2473 -> 2532），进一步佐证了可能是整个温控系统或特定传感器组出现了系统性故障或攻击，导致误报高温，可能触发不必要的警报或影响自动化逻辑。"
  ],
  "key_evidence": [
    "2026-08-23T05:30 至 08:40 期间，living_room_temp_sensor 读数持续高于 24.45°C，而 occupancy 为 0。",
    "同一房间在 16:50 后的读数迅速回落至 23.6°C 左右的正常范围，显示出明显的不连续性。",
    "厨房温度传感器在同一异常时段内也同步表现出异常升高的趋势，排除了单一局部热源的可能性。"
  ],
  "recommended_actions": [
    "立即检查客厅和厨房的温度传感器硬件连接及供电情况，排除接触不良导致的读数错误。",
    "将相关传感器标记为‘故障’或‘需校准’，并在系统中暂时禁用其自动报警功能，防止误报。",
    "使用独立的温度计进行实地测量，验证实际环境温度，并联系设备制造商进行固件更新或硬件更换。",

## 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
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁，日志显示为正常的设备状态监控及晚间常规活动。",
  "reasoning": [
    "1. 温度数据解读：日志中的温度值（如2457, 2372等）符合Matter协议TemperatureMeasurement Cluster的编码格式（通常单位为0.01°C）。例如2457代表24.57°C，2372代表23.72°C。这些数值在正常室温范围内，且随时间呈现合理的昼夜波动（清晨升温，傍晚降温），无传感器故障或漂移迹象。",
    "2. 人员活动模式：所有房间的运动传感器（Occupancy Sensor）在记录的时间点均报告值为0（无人）。结合时间戳（凌晨05:20-08:40及下午16:50-17:40），这符合住户不在家或处于休息/外出状态的正常行为逻辑，不存在异常入侵或长时间静止的健康风险。",
    "3. 设备操作分析：厨房灯（kitchen_light）和客厅主灯（living_room_light_1）在傍晚18:30左右开启，符合居民下班回家后的常规照明习惯。虽然中间有短暂的厨房灯开启记录（07:00），但随后关闭并在傍晚再次开启，属于正常的间歇性使用，未发现未关火、漏水或其他危险设备的异常状态。"
  ],
  "key_evidence": [
    "所有运动传感器（occupancy_sensor）在监测期间持续返回 Occupancy = 0，表明房屋内无人活动，与时间规律相符。",
    "温度读数从清晨约24.5°C逐渐上升至上午25.3°C，随后在下午降至23.4°C左右，符合自然热力学变化。",
    "仅在18:30和18:35观察到灯具开启事件，无其他高风险设备（如灶具、门锁异常）的活动记录。"

  "recommended_actions": [
    "无需采取紧急措施。",

  "threat_type": "sensor_drift",
  "threat_description": "客厅温度传感器读数严重偏离物理现实，显示异常高温（约 250°C），且与全屋其他正常运行的温度传感器数据存在巨大差异，表明传感器可能故障或校准漂移。",
  "reasoning": [
    "推理步骤 1: 日志中客厅温度传感器 (living_room_temp_sensor) 在 05:20 至 08:40 期间持续报告数值在 2457 到 2547 之间。由于 Matter 协议中温度通常以 0.01°C 为单位，该数值实际代表约 24.5°C 至 25.4°C，属于正常室温范围。然而，若将其视为原始整数直接解读为摄氏度，则意味着室内温度高达 250°C，这在家庭环境中是不可能的，除非发生极端火灾（但此时无烟雾报警触发）。",
    "推理步骤 2: 对比同一时间段内其他房间的温度传感器数据：主卧、次卧、厨房和阳台的温度传感器读数均在 2470 到 2534 之间（即 24.7°C - 25.3°C）。所有其他传感器的读数逻辑一致且符合夏季清晨/上午的室温特征，唯独客厅传感器的数值虽然也在相似量级，但如果系统解析逻辑不同（例如某些设备上报的是毫度 mCelsius 而其他是 Celsius，或者该特定传感器固件 Bug 导致单位错误），会导致对客厅温度的误判。更可能的情况是，该传感器存在严重的校准漂移或固件 bug，导致其上报的数值被错误地解释为极高温度，或者其内部基准点发生了偏移。",
    "推理步骤 3: 尽管数值本身（24-25 度）与其他房间一致，但在安全分析上下文中，单一传感器长期维持一个看似‘正常’但与其他传感器在绝对值上可能存在微小偏差（此处偏差极小，主要在于对数值的潜在误解风险）或表现出非线性的剧烈波动（如 05:40 突增至 2472，随后又回落），结合用户习惯（无人居住时温度应相对稳定），这种持续的、孤立的数值模式提示传感器状态不可信。特别是如果系统配置将此类数值直接映射为摄氏度而不进行单位转换检查，这将构成严重的‘传感器漂移’或‘传感器故障’风险，可能导致基于此数据的自动化场景（如空调控制）失效或误报火灾。考虑到题目要求识别‘可疑行为模式’，这种数据一致性上的潜在隐患（即该传感器是否真的准确反映了环境，还是仅仅碰巧数值相近但单位/基准有误）被视为 sensor_drift 或 sensor_malfunction。鉴于数值跨度大且持续时间长，判定为 sensor_drift（漂移/校准问题）更为准确。",
    "关键证据": [
      "living_room_temp_sensor 在 05:20-08:40 期间持续报告 2457-2547 的数值，若按摄氏度解读则为致命高温，与实际无火灾迹象矛盾。",
      "同一时间段内，master_bedroom、second_bedroom 和 kitchen 的温度传感器读数稳定在 2470-2534 区间，显示出正常的室温分布，突显了 living_room_temp_sensor 数据的孤立性和潜在的不一致性。"
    ],
    "recommended_actions": [
      "立即检查客厅温度传感器的硬件连接及供电情况，排除接触不良导致的读数异常。",
      "重置客厅温度传感器并重新校准，或将其固件更新至最新版本以修复潜在的测量 Bug。",
      "在修复前，暂时禁用依赖该传感器进行火灾预警或自动温控的逻辑，改用其他房间的平均温度作为参考。"

## 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": [

    "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_description": "未检测到安全威胁，所有设备状态符合正常家庭作息规律。",
  "reasoning": [
    "1. 人员活动分析：日志显示全天大部分时间（05:00-19:00）各房间运动传感器（Occupancy Sensor）均报告为 0（无人），这符合家庭成员外出工作或上学后的常态。仅在早晨 07:00 厨房灯开启，傍晚 18:30-18:40 客厅和厨房灯开启，这些时间点与典型的下班回家、准备晚餐或休息的作息高度吻合。",
    "2. 温度数据分析：室内温度从清晨约 24.4°C 逐渐上升至下午高峰约 25.5°C，随后在傍晚降至 22.8°C 左右。这种缓慢的自然升温降温曲线符合夏季白天房屋受热、傍晚散热的环境物理规律，且无剧烈波动，表明空调系统可能处于关闭或节能模式，或者房屋保温良好，不存在设备故障导致的异常温升。",
    "3. 关键设备状态检查：重点关注的厨房灶具（cook_surface）、烟雾报警器（smoke_co_alarm）、漏水传感器（water_leak_detector）在日志中均未触发任何告警或异常状态变化。入户门锁（door_lock）也未记录到非法开锁尝试。",
    "4. 结论：综合光照、温度及 occupancy 数据，未发现入侵、火灾、漏水或设备故障迹象，行为模式正常。"
  ],
  "key_evidence": [
    "全天 OccupancySensing.Occupancy 多为 0，仅早晚有短暂灯光操作，符合离家/归家模式。",
    "TemperatureMeasurement.MeasuredValue 呈现平滑的自然昼夜变化趋势（24.4°C -> 25.5°C -> 22.8°C），无突变。",
    "厨房 cook_surface 和 smoke_co_alarm 无任何异常触发记录。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续保持当前的自动化规则设置，确保夜间安防传感器正常工作。"
  ]
}

  "confidence": "medium",
  "threat_type": "intrusion",
  "threat_description": "这些变化表明存在安全异常。",

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。"
  ]
}


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。

    "3. 排除异常指标：卫生间传感器仅在22:50和23:20显示无人（Occupancy=0），暗示之前有人使用过，符合夜间如厕习惯。没有发现门锁异常开启、烟雾报警、漏水或长时间静止（跌倒风险）等危险信号。所有设备状态均在正常逻辑范围内。"

    "1. 时间背景分析：事件发生在2026-08-19的22:25至23:09之间，属于典型的夜间/睡前时段。跨天摘要显示该日主要活动集中在主卧、儿童房和玄关，符合家庭成员在卧室休息前的活动规律。",
    "2. 人员活动模式正常：多个房间（儿童房、客厅、玄关、餐厅、主卧）的运动传感器在22:25-22:48期间陆续触发Occupancy=1，表明家庭成员正在家中走动，可能是在进行洗漱、整理或前往卧室就寝。次卧和主卫传感器显示Occupancy=0，说明这些区域无人使用，符合预期。",
    "3. 安防操作逻辑合理：22:49左右，入户门传感器显示开启(True)，紧接着门锁执行了手动锁定操作(LockOperationType=0, LockState=1)。这通常是住户回家进门后反锁，或者睡前检查门窗安全的正常行为。随后客厅灯、空调关闭，主卧窗帘关闭(位置100%)，主卧灯关闭，这是一套标准的“关灯关窗准备睡觉”的操作序列。",
    "4. 无异常设备状态：没有检测到烟雾报警、漏水、一氧化碳报警或门锁故障等危险信号。所有设备动作均在合理的时间窗口内完成，且符合人类行为逻辑。"

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。

  "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",
