系统刚记录到以下一段设备状态变化。请评估这些变化是否已经构成安全风险，并说明原因。

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",

## 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",

    "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。

  "confidence": "medium",
  "threat_type": "intrusion",

  "threat_description": "检测到室内温度传感器数据严重漂移，数值异常高达 2369 (约 23.69°C 或原始单位错误)，且伴随非正常的温度波动模式，疑似传感器故障或被篡改。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，从 01:20 开始，所有房间的温度传感器（living_room, master_bedroom, second_bedroom, kitchen）同时上报数值。虽然初始值在 2300-2310 区间看似正常（假设单位为 0.1°C），但随后数值持续异常攀升。",
    "推理步骤 2: 关键异常点出现在 02:55 至 03:00 期间，厨房和次卧温度读数飙升至 2366-2369。如果单位是 0.1°C，这代表近 24°C 的高温，对于夜间无人居住（occupancy=0）的住宅来说极不自然；如果单位是整数°C，则直接表示室温超过 23°C 且仍在上升，考虑到凌晨时段通常气温下降，这种上升趋势违背物理规律。",
    "推理步骤 3: 结合 occupancy 传感器数据，在 02:00 至 03:30 期间，全屋无人员活动（Occupancy = 0）。在此情况下，温度不应出现剧烈且持续的单向升高（除非有外部热源入侵，但门窗传感器未报告开启）。更可能的情况是传感器固件 Bug、校准失效导致数值溢出/漂移，或者有人恶意修改了传感器上报的数据以掩盖真实环境状况（如火灾风险被忽略）。",
    "推理步骤 4: 阳台门在 02:07 关闭，灯光开启，随后客厅有人进入（02:09），但这发生在温度异常飙升之前。温度的异常变化与人员活动的时间线不完全匹配，进一步排除了单纯的人员行为导致的可能性，指向设备本身的问题。"

    "在温度异常飙升期间（02:00-03:30），所有房间 occupancy 传感器均报告为 0（无人），缺乏解释高温升高的合理热源来源。",
    "多个不同房间的温度传感器在同一时间段内表现出高度同步的异常数值增长，增加了系统性故障或数据注入攻击的可能性。"
  ],
  "recommended_actions": [
    "立即检查并更换所有受影响的温度传感器，排除硬件故障。",

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": "客厅温度传感器读数严重偏离物理现实，显示异常高温（2304-2437），且与同区域其他设备数据不一致，存在传感器漂移或故障风险。",
  "reasoning": [
    "推理步骤 1: 分析日志发现，从 2026-07-16T01:40:00 开始，living_room_temp_sensor 报告的温度值在 2304 到 2437 之间波动。考虑到 Matter 协议中温度通常以 0.01°C 为单位，这些数值换算后约为 23.04°C 至 24.37°C，虽然看似合理，但需结合上下文判断。",
    "推理步骤 2: 对比同一时间段内其他房间（如 master_bedroom, kitchen）的温度传感器数据，其数值范围也在 23xx-24xx 区间，表面上看全屋温度一致。然而，仔细观察 2026-07-16T02:25:00 和 2026-07-16T02:30:00 的数据，living_room_temp_sensor 突然跳变至 2345/2348，而 kids_room_temp_sensor 在同一时刻为 2334/2338，两者差异极小但趋势不同步。更关键的是，若将数值视为整数摄氏度（某些旧协议或配置错误可能导致单位丢失），则 2437°C 显然不可能；若视为毫开尔文或其他单位则逻辑不通。但在智能家居语境下，最可能的解释是：该传感器在夜间无人时段（occupancy=0）持续上报异常高值，且数值随时间呈现非自然的线性爬升（从 2304 升至 2437），这不符合热力学自然冷却或缓慢变化的规律。",
    "推理步骤 3: 进一步观察 occupancy 状态，在 2026-07-16T02:30:00 至 04:30:00 期间，living_room_occupancy 多次报 0（无人），但温度却持续上升并达到 2437（假设单位为 0.01°C 即 24.37°C 仍偏高，但若系统误报为绝对温度则极度危险）。更重要的是，在 2026-07-17 和 2026-07-18 的类似时段，温度再次出现类似的异常爬升模式（2308 -> 2428），这种跨天重复出现的‘无人时温度异常升高’模式，强烈暗示传感器本身发生漂移、校准失效或被干扰，而非真实环境温度变化。此外，厨房灯在凌晨自动开关的行为也略显可疑，但与温度问题相比次要。核心威胁在于温度传感器数据不可信，可能导致空调控制失效或火灾预警系统误判。",
    "key_evidence": [
      "2026-07-16T01:40:00 至 04:30:00 期间，living_room_temp_sensor 在无人员活动（occupancy=0）的情况下，温度读数从 2304 持续攀升至 2437，呈现非自然的热积累曲线。",

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。

请按以下 JSON 格式回答：

```json

## 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",

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 2: 尽管无人，living_room_temp_sensor 的读数却从正常的 23.15 (0.2315°C? 假设单位是 mK 则对应 23.15°C) 开始，在凌晨时段异常攀升至 24.39 (0.2439°C)，并在随后几天重复出现类似的凌晨升温模式（如 08-18 和 08-19）。",
    "推理步骤 3: 关键疑点在于，同一时间段内 second_bedroom_temp_sensor 也出现了几乎完全同步的数值波动（例如 03:30 时两者均为 2388/2388，04:00 时分别为 2391/2402）。物理上，两个不同房间的温度不可能在同一分钟精确同步变化，除非存在外部干扰、传感器校准严重漂移或被恶意攻击导致的数据伪造。考虑到 Matter 协议的安全性，这种跨设备的高度相关性更指向传感器本身的硬件故障（Sensor Drift）或固件层面的数据注入攻击。",
