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",

    "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。

    "环境监控正常：窗户接触传感器在 18:55 变为 False（打开），但结合上下文可能是为了通风或取物，且未伴随入侵警报或其他异常传感器联动；所有运动传感器读数与人员移动轨迹一致。",
    "无危险信号：全篇日志中未出现烟雾报警器触发、漏水检测、门锁故障（如反复尝试开锁）、传感器数据漂移或丢失等典型安全威胁特征。"
  ],
  "key_evidence": [
    "front_door_lock 解锁后立即跟随 living_room_occupancy 变为 1，表明是合法住户返回。",

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",

    "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。

    "环境与设备状态：温度传感器读数（24-25°C）处于舒适范围且波动正常；未检测到烟雾报警触发、漏水事件或门锁异常操作（仅见正常的开门/关门记录）；所有传感器数据无漂移或卡死现象。"
  ],
  "key_evidence": [
    "连续三天作息规律：每日清晨 06:30-07:00 间卧室由无人变为有人，随后进行厨房活动。",
    "门锁操作正常：仅在早晨出门和傍晚回家时出现手动锁/解锁操作，无暴力破解或异常尝试。",
    "环境参数稳定：全屋温度维持在 24-25°C 之间，无极端高温或低温报警。"
  ],

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
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",

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

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。

  "threat_description": "客厅温度传感器报告了异常的高数值（约 23.8°C x100 = 23.8°C? 不，Matter 协议中整数通常代表毫摄氏度或特定缩放值，此处 2384 对应 23.84°C 是合理的，但结合上下文看，数值在 2300-2400 之间剧烈波动且与卧室/厨房温差逻辑不符，更可能是单位误解或传感器故障导致的数据漂移。然而，仔细观察数据：卧室约 22°C (2200)，厨房约 23°C (2300)。如果单位是 0.1°C，则 2384=23.84°C，这是正常的室温范围。但是，请注意时间戳 16:20 到 17:50 期间，客厅温度从 23.84°C 持续下降到 23.20°C，而卧室和厨房的温度读数却保持在 22.0°C - 23.5°C 之间相对平稳。更重要的是，在 19:05 厨房温度突然跳变至 24.21°C (2421)，随后灶具开启。最大的疑点在于：所有温度传感器的数值都在 2200-2400 范围内，如果这是毫摄氏度，那么 23.84°C 是完全正常的室温。是否存在真正的异常？\n\n重新审视数据模式：\n1. 温度数值：2384 -> 23.84°C。这在夏季傍晚是正常的。\n2. 行为序列：18:20 门锁被打开并锁定，玄关灯开，客厅灯开，空调开启（制冷模式 SystemMode=3）。这符合回家场景。\n3. 19:07 厨房灯开，灶具开启。这也符合正常烹饪场景。\n4.  occupancy 状态：卧室有人，客厅后来也有人。一切看起来都很正常。\n\n等等，让我再次检查是否有“陷阱”。\n- 16:20 客厅温度 23.84°C。\n- 16:30 客厅温度 23.91°C。\n- ... \n- 17:20 卧室 22.44°C，厨房 23.50°C。\n- 18:20 门锁操作（LockOperationType=1 通常是解锁？还是锁定？Matter Lock 标准中，LockState=2 是 Locked。Event Type=1 可能是 Unlock 或 Lock。结合后续 DoorLock.LockState=2 (Locked) 和 Entrance Light On，这显然是主人回家进门并锁门的过程。\n- 18:29 门锁锁定。\n- 18:29:20 客厅有人。\n- 18:29:28 空调开启。\n- 19:07 厨房灶具开启。\n\n所有事件都符合“主人下班回家，进屋，开空调，做饭”的正常生活流。\n\n难道没有异常？\n再仔细看温度数据。如果 Matter 协议中 TemperatureMeasurement.MeasuredValue 的单位是 0.1 度 Celsius，那么 2384 就是 23.84 度。这是完全正常的。\n如果单位是 1 度，那就是 2384 度，那肯定是火灾。但考虑到卧室只有 2244 (22.44 度)，厨房 2350 (23.50 度)，显然单位不是 1 度。所以单位是 0.1 度。\n\n那么，有没有其他异常？\n- 16:30 客厅有人为 0，但 16:43 卧室有人。这是可能的，人在卧室。\n- 18:20 门锁动作后，18:29:20 客厅才检测到有人。中间有 10 秒延迟，可能是因为人刚进门还在玄关，或者传感器响应延迟，不算异常。\n- 19:05 厨房温度突增到 24.21°C，紧接着 19:07 开灯，19:07:30 开灶具。温度升高是因为灶具预热或环境变化，逻辑自洽。\n\n结论：这是一段非常典型的、无异常的智能家居日志，记录了用户下班回家的完整流程。\n\n**修正思考**：是否有任何细微的不一致？\n- 16:20-17:50 期间，客厅温度持续下降（23.84 -> 23.20），而卧室和厨房温度相对稳定或略有上升。如果此时家里没人（occupancy=0），温度应该保持恒定（除非空调开了）。日志显示 16:30 客厅 occupancy=0。如果空调没开，温度不应该降这么多。但日志里空调是在 18:29 才开的。这意味着在 16:20-17:50 期间，客厅温度自然下降了 0.6 度。这在夏天晚上是可能的（室外降温）。\n- 18:29 开门时，客厅 occupancy 从 0 变为 1。合理。\n- 19:05 厨房温度 24.21，比之前的 23.x 高。合理，因为快开火了。\n\n**最终判断**：没有发现安全威胁。所有设备行为符合住户习惯，数据逻辑自洽。\n\nWait, I need to be extremely careful. Is there a "Sensor Drift" or "Sensor Malfunction"?\nLook at the temperature values again.\nLiving Room: 2384, 2391, 2383... down to 2320. Range ~0.6 degrees over 2 hours. Normal.\nBedroom: 2244, 2255... down to 2188. Range ~0.5 degrees. Normal.\nKitchen: 2350... up to 2421. Jump of 0.7 degrees right before cooking starts. Normal.\n\nIs it possible the user is asking about the *pattern* of events?\n- 07:15 Front door contact False (Open), then True (Closed). User left home in morning.\n- 18:20 Front door contact False (Open), then Lock Operation, then State=2 (Locked). User returned and locked door.\nThis is standard daily routine.\n\nIs there any contradiction?\n- 16:30 Living room occupancy = 0. Correct, user was likely in bedroom (occupancy=1).\n- 18:29 Entrance light ON, Living room light ON, AC ON. Consistent with returning home.\n- 19:07 Cook surface ON. Consistent with dinner prep.\n\nThere seems to be NO anomaly. The system is functioning as expected for a resident's evening routine.\n\nLet me double check the "Threat Types". If I must find something, could it be "abnormal_inactivity"? No, activity is high.\nCould it be "sensor_drift"? The temperatures are consistent with each other (Living ~23.8, Bedroom ~22.4, Kitchen ~23.5). The difference between living room and bedroom is about 1.4 degrees, which is plausible given their positions relative to windows/doors.\n\nOkay, I will conclude `is_anomaly: false`.\n\n**Wait, one more check**:
At 16:20, Living Room Temp = 23.84.
At 16:30, Living Room Occupancy = 0.
If no one is there, and AC is off (AC turned on at 18:29), why did the temp drop from 23.84 to 23.20 over an hour?
In summer, if the house is sealed, indoor temp usually follows outdoor temp slowly. A drop of 0.6C in an hour is possible if the outside air cooled down significantly or there was a breeze. It's not impossible.
However, compared to the bedroom (which stayed around 22.4-22.5), the living room dropped faster. This might suggest the living room has better ventilation or the sensor is slightly less stable, but not enough to flag as a critical malfunction without historical baseline. Given the task is to identify *security threats* or *safety risks*, this minor drift is likely noise.

Let's look at the lock event again.
18:20 Contact False (Door Open).
18:29 Lock Operation (Manual).
18:29 State=2 (Locked).
18:29:02 Contact False (Door Open??).
Wait!
Log: `[2026-08-27T18:29:02] front_door_contact | BooleanState.StateValue = False`
Then immediately after locking:
`[2026-08-27T18:29:14] entrance_light | OnOff.OnOff = True`
`[2026-08-27T18:29:20] living_room_occupancy | OccupancySensing.Occupancy = 1`

Sequence:
1. 18:20: Door opens (False).
2. 18:29: Lock operation performed.
3. 18:29:02: Door contact reports False (Open). **CRITICAL POINT**.
   If the door was just locked at 18:29:00, how can it be open at 18:29:02?
   Possibility A: The person opened the door, unlocked it (or the lock cycle took time), walked in, and the contact sensor reported "Open" briefly while they were crossing the threshold or due to mechanical lag, then the lock engaged?
   But the log says `LockState = 2` (Locked) at 18:29:00.
   Then at 18:29:02, Contact = False (Open).
   Then at 18:29:14, Light turns on.
   Then at 18:29:20, Occupancy = 1.

   If the door is locked (State=2), the contact sensor should ideally report Closed (True) unless the sensor is faulty or the door wasn't fully latched yet.
   However, in many smart locks, the "Contact" sensor is separate from the "Lock" motor state. Sometimes the door is physically closed but the latch hasn't engaged, or the sensor has a delay.
   BUT, reporting "Open" (False) 2 seconds after "Locked" (State=2) is suspicious. It implies either:
   1. The door was forced open immediately after locking (Burglary attempt?).
   2. The sensor is stuck/malfunctioning.
   3. The sequence is: Person opens door (18:20), enters, closes door, lock engages (18:29). At 18:29:02, maybe the door was still slightly ajar during the closing process, or the sensor glitched.

   Let's re-read the timestamps carefully.
   18:20:00 - Contact False (Open).
   18:29:00 - Lock Operation + LockState=2 (Locked).
   18:29:02 - Contact False (Open).

   If the door was locked at 18:29:00, it should be closed. Why does the contact say Open 2 seconds later?
   Unless... the "LockState=2" means "Locked" but the physical door is still being pushed against the frame by wind or someone trying to enter?
   Or, more likely, this is a **Sensor Malfunction** or **Sensor Drift** where the contact sensor fails to update correctly after the door is closed and locked.

   However, looking at the next events:
   18:29:14 - Light ON.
   18:29:20 - Occupancy = 1.
   The user is inside. The lights are on. The AC is on.
   Did anyone break in? Unlikely if the user is inside and turning on lights.
   Is it a tailgating attempt? If someone tried to open the door after it was locked, we would expect another "Lock Operation" or a sustained "Open" signal followed by an alarm. Here, the "Open" signal lasted only 2 seconds (18:29:02) and then presumably went back to True (Closed) implicitly, as the user settled in.

   Actually, let's look at the very beginning of the day.
   07:15:29 Contact False (Open).
   07:15:35 Contact True (Closed).
   This is normal leaving.

   Now the evening return.
   18:20:00 Contact False (Open).
   18:29:00 Lock Engaged.
   18:29:02 Contact False (Open).

   Hypothesis: The user opened the door, entered, and the door closed. The lock mechanism engaged. The contact sensor might have a debounce issue or the door didn't seal perfectly initially, causing a brief "Open" reading. Given the subsequent normal behavior (lights on, occupancy detected, AC on), this is likely a benign sensor glitch rather than a security breach.

   Is there anything else?
   What about the temperature at 19:05? 24.21. Then cook surface ON.
   Is it possible the cook surface was already on? No, it says ON at 19:07:30.

   Okay, I'm leaning towards **No Anomaly** because the context (user inside, lights on, AC on) overrides the 2-second sensor glitch. The sensor glitch is too short to indicate a break-in.

   Wait, is there a "Tailgating" risk?
   If the door was locked, and then reported open, could someone have slipped in?
   If so, why did the occupancy sensor detect the user at 18:29:20? And why did the user turn on the kitchen stove later?
   If a burglar got in, they wouldn't turn on the stove and wait for the owner to come back? Or maybe the owner came back, saw the stove, and thought nothing of it?
   But the log shows the *owner's* actions (turning on AC, lights, stove). We assume the logs reflect the authorized user's actions unless proven otherwise.

   Therefore, the most logical conclusion is that the 2-second "Open" reading was a sensor artifact (e.g., door settling, magnetic switch bounce) and not a security incident.

   Final Decision: **No Anomaly**. The system behaves normally for a resident returning home. The brief sensor fluctuation is within acceptable noise margins for this type of analysis.

## 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",

    "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。

  "threat_description": "厨房温度传感器数据严重异常，数值远超物理极限且伴随设备状态丢失，极可能为传感器故障或信号干扰。",
  "reasoning": [
    "推理步骤 1: 分析厨房温度传感器日志，发现从 19:05 开始，读数从正常的 24°C (2419mK) 急剧上升至 26.0°C (2601mK)，并在 19:10 达到 24.9°C (2494mK)。虽然夏季高温可能导致升温，但随后在开启灶具后数值继续非理性飙升。",
    "推理步骤 2: 关键异常点出现在 19:15-19:20。当用户开启厨房灯和灶具时，温度读数瞬间飙升至 25.53°C (2553mK) 和 26.01°C (2601mK)。考虑到 Matter 协议中温度通常以毫开尔文 (mK) 为单位，2601mK 约等于 -272.15°C（绝对零度附近），这在物理上是不可能的；或者即使单位是摄氏度，该数值也远超任何室内环境或正常烹饪产生的温度。",
    "推理步骤 3: 最致命的证据是 19:16:00 的日志显示 `kitchen_temp_sensor` 值为 `None`。这表明传感器在尝试报告极端异常值后立即失效或通信中断。结合之前不合理的数值跳变，这符合典型的传感器硬件故障、校准错误或无线信号被强干扰的特征，而非真实的火灾风险（因为烟雾报警器未触发且无其他火情迹象）。",
    "推理步骤 4: 排除误报：客厅和卧室的温度变化趋势相对平稳且符合空调运行逻辑，唯独厨房传感器表现出独立的、违背物理规律的剧烈波动和断连，确认问题局限于该特定传感器。"
