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
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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",

    "2.  occupancy 模式分析：各房间的运动传感器（occupancy_sensor）在白天时段（12:00-19:55）频繁触发为 '1'（有人），且在卫生间等短暂停留区域有 '0'（无人）的记录，这符合独居老人在家中日常活动（如做饭、休息、如厕）的行为逻辑。没有发现长时间静止不动导致的‘异常不活动’警报，也没有非正常时间的入侵迹象。",
    "3. 设备协同与一致性：客厅、卧室、厨房的温度传感器读数之间存在一定的温差（如卧室较凉，客厅受阳光或活动影响较热），这是正常的建筑热工现象。同时，运动传感器的活跃时间与温度变化的时间段大致吻合（如中午至下午活动较多，温度略有上升后随时间回落），表明设备工作正常且数据可信。"

  "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 254°C），而卧室温度正常且呈下降趋势，表明传感器存在漂移或故障。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，从 09:00 到 11:50，living_room_temp_sensor 的 MeasuredValue 持续在 2535-2554 之间波动。由于 Matter 协议中温度通常以 0.01°C 为单位，该数值换算后约为 25.35°C - 25.54°C。虽然这个数值本身在舒适范围内，但需结合上下文判断其合理性。",
    "推理步骤 2: 对比同一时间段内的 bedroom_temp_sensor 数据（如 12:20 为 24.31°C，15:00 为 23.40°C），卧室温度随时间自然下降，符合独居老人白天活动、夜间休息或空调运行的正常热力学规律。",
    "推理步骤 3: 关键异常点出现在 17:00:00。此时 living_room_temp_sensor 突然跳变至 2580 (25.80°C)，紧接着在 17:15:00 又跳回 2261 (22.61°C)。这种在短时间内剧烈震荡且与卧室温度变化趋势不一致（卧室在持续缓慢下降）的现象，排除了环境温度突变的可能性，极大概率是传感器校准失效、信号干扰导致的读数漂移（Drift），或者是设备固件 Bug 导致的数值溢出/错误报告。考虑到用户是独居老人，错误的温度反馈可能导致空调系统误判（例如认为太冷而过度制冷，或反之），属于潜在的安全隐患。",
    "修正推理：重新审视数值范围。若 MeasuredValue = 2540 代表 25.40°C，则全天大部分时间客厅温度都在 25°C 左右，这本身是正常的室温。但是，观察 17:00 的数据：Living Room 瞬间变为 25.80°C，随后迅速回落。更关键的异常在于 **17:00 之前** 的数据稳定性与 **17:00 之后** 的剧烈变化。实际上，最大的疑点在于 **17:00:00** 这一时刻，Living Room 和 Bedroom 同时上报了极高的数值（2580 和 2520? 不，Bedroom 是 2580，Living Room 是 2520）。等等，让我再次仔细核对 17:00 的行。",
    "最终确认推理：在 17:00:00，日志显示 `bedroom_temp_sensor` 为 2580 (25.80°C) 和 `living_room_temp_sensor` 为 2520 (25.20°C)。这两个值相对于之前的趋势（卧室一直在降，客厅一直在微降）来说，出现了异常的回升。特别是卧室温度在 16:40 还是 22.80°C，17:00 突然变成 25.80°C，温差巨大且无合理解释（如刚进入房间未稳定即上报？但 occupancy 也是 1）。这种非线性的、违背热惯性规律的突变，被判定为 Sensor Drift（传感器漂移）或 Malfunction（故障）。",
    "再次修正：仔细看 17:00 的那一行：`[2026-07-08T17:00:00] bedroom_temp_sensor | ... = 2580` 和 `[2026-07-08T17:00:00] living_room_temp_sensor | ... = 2520`。之前的卧室温度是 22.80 (16:40) 和 22.93 (16:15)。从 22.8 跳到 25.8 是非常反常的。同时，客厅从 23.79 (16:20) 跳到 25.20。这种同步的、大幅度的温度回升，在没有人员大量聚集（occupancy 均为 1）的情况下，极有可能是传感器故障或数据漂移。",
    "结论：尽管 25°C 左右的温度对人类来说是舒适的，但在智能家居安全分析的语境下，传感器读数的**突变性**和**违背物理规律的趋势反转**（持续降温后突然大幅升温）构成了异常模式。对于独居老人，不可靠的温度数据可能导致温控设备失效，引发过热或过冷风险。"

    "该突变发生在无人进入新区域（occupancy 保持为 1）的情况下，且与之前数小时持续缓慢降温的热力学趋势完全相反。",

## 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",

    "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",

    "推理步骤 3: 结合住户为独居老人，厨房是火灾高风险区域，一个不可靠的温度传感器可能导致烟雾报警器误报（因高温触发）或在真实火情下漏报，构成严重的安全隐患。"
  ],

  ],
  "recommended_actions": [
    "立即检查厨房温度传感器的电池电量及物理连接是否松动。",
    "联系 Matter 设备管理员或厂商重置该传感器，并重新校准其温度阈值。",

## 任务
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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": "客厅灯光及环境传感器数据符合正常晚间居家活动模式，未发现安全威胁或设备故障。",
  "reasoning": [
    "1. 灯光控制逻辑正常：日志显示在 20:10 开启客厅主灯并设置亮度为 180（约70%），随后在 20:18 将亮度调低至 30（约12%）。这种‘先开亮后调暗’的操作符合用户准备休息或观看电视时的典型行为习惯，属于正常的用户交互，而非设备卡死或异常闪烁。",
    "2.  occupancy 状态与时间匹配：从 14:21 至 21:56，客厅运动传感器持续报告 Occupancy = 1，表明客厅内有人活动。结合时间点（下午至深夜），这符合家庭成员在客厅休闲、用餐或活动的常态，未出现长时间无人却误报有人，或有人却无感知的异常情况。",
    "3. 温度数据趋势合理：客厅温度从 14:15 的 24.57°C 逐渐下降至 22:00 的 22.46°C。这一降温过程与傍晚时段室外气温降低以及可能的空调运行有关，数值变化平滑且符合物理规律，未见传感器漂移或故障导致的突变。"

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
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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: ...",

    "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": "阳台洗衣机按正常程序运行，状态变化符合预期，未发现安全威胁或设备故障。",
  "reasoning": [
    "1. 识别关键事件：日志显示在 2026-08-15T10:00:00，阳台洗衣机（balcony_laundry_washer）的 OperationalState 变为 1（通常表示开始运行或处于活动状态）。",
    "2. 验证运行时长与倒计时逻辑：在 T10:20:00，CountdownTime 为 2400秒（40分钟）；在 T10:40:00，CountdownTime 为 1200秒（20分钟）。这表明设备正在执行一个标准的洗涤周期，且剩余时间随时间推移线性减少，符合正常家电工作逻辑。",
    "3. 确认任务完成：在 T11:00:00，OperationalState 变回 0（停止/空闲），此时距离开始运行正好过去了1小时，与之前的倒计时逻辑吻合（假设初始设定可能略长于实际运行或包含其他阶段，但整体流程完整）。",
    "4. 排除异常模式：在此期间，没有检测到入侵传感器触发、漏水报警或烟雾报警等关联风险事件。所有温度传感器读数也在合理范围内波动，未出现极端值。"

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",

    "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。

  "reasoning": [
    "推理步骤 1: 日志显示在 19:01 开启厨房灯后，19:28 关闭灶具前，厨房温度传感器读数从正常的 2300-2400 (约 23-24°C) 异常飙升至 2675 (约 26.7°C)，随后在 20:10 再次跳变至 2419，并在 20:20 骤降至 2335。这种剧烈且不符合物理规律的波动（尤其是短时间内超过 200 个单位的变化）表明传感器读数不可靠。",
    "推理步骤 2: 尽管灶具在 19:28 被关闭，但传感器读数并未如预期般稳定或缓慢下降，而是在 19:45 仍显示高达 2636 的数值，直到 20:10 才回落。这与卧室和客厅温度传感器的平稳变化形成鲜明对比，排除了环境温度自然变化的可能性。",
    "推理步骤 3: 结合 Matter 协议标准，TemperatureMeasurement.MeasuredValue 通常以 0.1°C 为单位。数值达到 2600+ 远超正常室温范围，极可能是传感器硬件故障、校准丢失或通信干扰导致的‘传感器漂移’或‘传感器故障’。若该传感器用于联动烟雾报警器或自动切断电源，此故障将直接导致家庭面临真实的火灾隐患。"

## 任务
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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，日志显示为正常的早晨起床及离家准备流程。",
  "reasoning": [
    "1. **夜间至清晨状态正常**：从00:00到06:40，所有主要房间（主卧、客厅、浴室）的运动传感器均显示无人（Occupancy=0），符合深夜睡眠时的行为模式。温度数据呈现缓慢上升的自然趋势，无异常波动。",
    "2. **起床活动逻辑连贯**：06:44浴室有人，随后06:55主卧有人，07:03浴室灯关闭，07:05客厅灯开启。这符合典型的“起床-洗漱-整理”的早晨作息顺序。",
    "3. **离家行为一致**：07:18门锁上锁（LockState=2通常表示已锁定/已启用），紧接着入户门传感器触发（BooleanState.StateValue=True，在Matter中Contact Sensor通常True代表闭合/关闭，False代表打开；此处结合上下文，若门锁已锁且人离开，门应处于关闭状态）。07:28玄关运动传感器被触发，表明住户经过玄关区域。",
    "4. **后续活动合理**：07:48和08:08等时间点玄关再次有运动检测，可能是住户在家中进行其他活动或短暂返回取物，但并未伴随任何入侵迹象（如门锁被非法开启、窗户异常打开等）。整体时间线和设备联动符合人类日常行为逻辑。"

  "threat_description": "检测到疑似非法入侵：在住户正常作息期间（清晨），入户门锁被远程或物理解锁，随后门传感器立即触发开启状态，且玄关区域出现异常的人员活动轨迹。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，在 07:18:20 发生关键事件，入户门锁 (front_door_lock) 状态变为 '2' (通常代表 Unlock/已解锁)，紧接着在 07:18:28 入户门接触传感器 (front_door_contact) 状态变为 True (门已打开)。",
    "推理步骤 2: 结合上下文，此时家中所有房间 (living_room, master_bedroom, second_bedroom, bathroom) 的 occupancy 传感器均报告为 0 (无人)，表明屋内无人在场。然而，仅 3 分钟后 (07:28:23)，玄关运动传感器 (entrance_occupancy) 突然检测到有人进入 (Occupancy = 1)。",
    "推理步骤 3: 这种‘全屋无人 -> 门锁瞬间解锁 -> 门开 -> 玄关有人’的序列不符合正常的起床出门模式（通常会有卧室有人、客厅有人等前序动作）。此外，日志中厨房温度持续异常升高至 254°C+ (实际应为 25.4°C，但数值本身极高可能暗示传感器故障或极端环境，不过相对于入侵威胁，门锁逻辑更直接)，而入侵行为发生在高温背景下增加了潜在风险。最核心的证据是门锁与开门状态的紧密耦合以及随后的陌生人进入迹象。",
    "推理步骤 4: 虽然存在温度传感器读数异常高 (如 2546 mK = 22.3°C? 不，Matter 温度通常是毫开尔文，2546mK=2.2K 绝对零度附近？或者单位是 0.1°C? 若按 0.1°C 算则是 254.6°C，这极不合理；若按 10mK 算则是 22.3°C。假设日志中的 2546 代表 22.3°C 左右是正常的室温波动，或者是传感器漂移。但无论温度如何，门锁逻辑链条完整且违背常理，构成主要威胁。)",
    "修正推理步骤 4: 重新审视温度数据，Matter 协议中 TemperatureMeasurement.MeasuredValue 单位通常为毫开尔文 (mK)。2296 mK ≈ 2.1°C (过低), 2546 mK ≈ 2.3°C。如果这是摄氏度 * 10，则 22.96°C 合理。考虑到 07:18 时厨房温度达到 2546 (假设是 25.46°C)，这在夏季清晨是可能的。因此温度数据本身可能是正常的室温记录，不应作为主要报警依据，重点应放在门锁和人员进出逻辑上。",
    "最终确认：核心异常在于 07:18 分的全屋无人状态下发生的门锁解锁和开门，以及随后玄关出现的非预期人员活动。"
