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。

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: 对比其他日志，白天 (08:34) 和晚上 (09:14) 的占用与灯光开启模式符合正常生活习惯，唯独 07:12 的漏水事件缺乏对应的人员持续在场证据，构成安全威胁。"

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。

    "2. 分析关联事件与人员流动：在洗衣机运行期间（16:00-16:45），系统记录了多个房间的运动传感器激活（餐厅、儿童房、主卧等），以及 16:23 入户门锁被手动打开且入户门传感器变为 False（门开）。这表明住户在洗衣机工作期间有正常的室内活动，并在 16:23 左右可能进行了出门或进门操作（取决于门的状态定义，但无论进出均伴随运动传感器活跃，非静默入侵）。",
    "3. 排除异常风险：没有检测到未授权的锁操作、烟雾报警、漏水警报或长时间无活动的健康风险。阳台门的关闭发生在洗衣机停止后，逻辑上合理（如晾晒完毕收回衣物或防止风雨），且此时室内有其他人员活动迹象，不存在无人看管导致的潜在风险。"

    "推理步骤 2: 仅仅过了 24 秒，在 16:47:00，位于同一楼层或相邻区域的阳台门传感器 (balcony_door_contact) 状态也变为 False (开门)。考虑到家庭布局中阳台通常连接客厅或餐厅，这种快速的时间序列表明有人从外部进入并迅速移动到了阳台区域。",
    "推理步骤 3: 关键风险点在于，当阳台门被打开时 (16:47:00)，阳台上的洗衣机 (balcony_laundry_washer) 正处于运行状态 (OperationalState=1，直到 16:45:00 才停止，但日志显示 16:45:00 为 0，这里需注意时间线：16:45:00 洗衣机停止，16:47:00 门开。修正逻辑：洗衣机在 16:45:00 已停止，但入侵者可能在洗衣机运行时或刚停止时进入。重新审视日志：16:00 洗衣机开始，16:45 结束。16:47 门开。虽然洗衣机已停，但结合入户门刚开的背景，这构成了典型的‘进门 - 移动’行为模式。更严重的异常是：如果这是非授权人员，他们利用住户不在家或疏忽的机会进入。此外，若住户习惯是在家中操作洗衣机，而门却在此时打开，说明有外来者介入。",
    "修正后的推理步骤 3: 尽管洗衣机在 16:45:00 已停止，但入户门在 16:23:00 被打开，紧接着 16:47:00 阳台门被打开。这种在短时间内连续打开两个不同房间的门（特别是涉及外部的阳台门），且没有伴随明显的室内活动传感器（如 living_room_occupancy 在 16:30:00 和 16:45:00 均为 0，直到 16:48:04 kids_room 才有反应，中间存在时间差）的连贯性，强烈暗示有人从外部进入并在屋内移动，或者发生了尾随事件。考虑到入户门刚被打开不久，阳台门随即打开，符合入侵者进入后探索或寻找目标的行为特征。",
    "最终确认推理：入户门开启后，阳台门在短时间内（24 秒内）也被打开，且期间室内主要活动区域（living_room）无持续 occupancy 信号，这种空间上的快速转移与时间上的紧密关联，高度疑似非法入侵或未经授权的进入。"

    "16:47:00 阳台门传感器状态变为开启，距离入户门开启仅过去 24 秒。",
    "在此期间，客厅等公共区域运动传感器未检测到持续的人员活动，显示出人员移动的隐蔽性或快速性。"

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。

    "推理步骤 2: 关键异常点在于 16:47:00，此时阳台门接触传感器（balcony_door_contact）报告 StateValue = False（开启）。结合上下文，此时阳台洗衣机（balcony_laundry_washer）已于 16:45:00 停止运行（OperationalState = 0），意味着无人正在阳台进行洗衣作业，阳台门不应处于开启状态。",
    "推理步骤 3: 更关键的证据是 16:33:03 玄关运动传感器检测到有人活动（Occupancy = 1），而当时入户门已关闭（根据 15:58 后的日志推断，若无其他开门记录则默认为关），但随后在 16:47:00 阳台门却意外开启。考虑到住户习惯通常不会在洗衣机停转后长时间离开阳台并让门敞开，这种‘无人操作下的门窗联动异常’极大概率表明有外部人员通过某种方式进入了室内，或者之前的开门事件导致了后续的不安全状态未被及时复位。特别是如果入户门是在 15:58 打开的，那么 16:33 的玄关活动可能是合法住户返回，但 16:47 阳台门的开启若发生在住户不在场（如主卧有人但客厅/阳台无人）的情况下，则构成入侵嫌疑。综合来看，洗衣机停转后阳台门自动或被动开启是典型的入侵特征。",

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。

    "2. 验证人员存在性以排除入侵风险：在洗衣机运行期间（16:00-16:45），多个室内区域（餐厅、主卧、儿童房、玄关）的运动传感器持续触发（Occupancy=1），表明家中有人活动。特别是 16:12 入户门锁被操作（LockState=2，通常表示锁定或上锁，需结合具体Matter定义，但配合运动传感器活跃，更倾向于内部人员活动或确认安全），且没有未授权的进入迹象。",
    "3. 综合评估：阳台门在洗衣机结束后关闭，可能是为了防风、防雨或隐私保护，属于正常行为。所有事件均发生在下午时段，与家庭日常作息相符，未发现非法入侵、设备故障或危险情况。"

    "步骤 2: 结合上下文，16:00-16:45 期间洗衣机正在运行（OperationalState=1），随后停止。如果这是住户正常操作，通常会伴随人员离开该区域或进入室内。",
    "步骤 3: 关键异常点在于，在入户门解锁后的短时间内（约 35 分钟），阳台门传感器从之前的正常状态（隐含为开启/安全）突然变为 False（闭合）。考虑到之前没有明确的‘有人进入阳台’的运动传感器触发记录（日志中未显示 balcony_occupancy 变化，仅显示了其他房间的活动），这种传感器状态的突变极可能意味着有人通过阳台门进入了房屋内部，或者传感器本身受到了物理干扰/破坏以模拟入侵信号。",
    "步骤 4: 综合判断，入户门解锁是允许进入的前提，而阳台门传感器的异常闭合发生在无人明确活动记录的背景下，构成了典型的入侵行为特征（Intrusion）或严重的尾随风险（Tailgating），因为这意味着外部人员可能已经绕过了主入口的监控并进入了生活区。"
