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",
  "reasoning": [
    "推理步骤1: ...",
    "推理步骤2: ...",
    "推理步骤3: ..."
  ],

    "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": true,
  "confidence": "medium",
  "threat_type": "behavioral_anomaly",
  "threat_description": "半夜反复开关同一盏灯",
  "reasoning": [
    "推理步骤1: 深夜反复开关同一设备",
    "推理步骤2: 间隔很短",
    "推理步骤3: 符合意识混乱或异常行为模式"
  ],
  "key_evidence": [
    "深夜反复开关同一设备",
    "间隔很短",
    "符合意识混乱或异常行为模式"
  ],
  "recommended_actions": [
    "判定为夜间行为异常，建议关注老人认知状态。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "独居老人家中客厅温度在夜间无人状态下持续异常升高，且伴随空调关闭，存在严重的火灾隐患。",
  "reasoning": [
    "1. 环境状态分析：日志显示从 00:30 开始，所有房间（living_room, bedroom, kitchen, bathroom, entrance）的运动传感器均报告 Occupancy = 0，表明整栋房屋处于完全无人状态。",
    "2. 异常模式识别：在无人状态下，客厅温度传感器读数从凌晨 00:10 的约 22.8°C (2284mK) 持续攀升至 04:15 的约 24.2°C (2419mK)，温差超过 1.4°C。更严重的是，厨房温度也同步上升，最高达 23.78°C (2378mK)。",
    "3. 设备行为矛盾：通常夜间无人时，空调应开启以维持舒适温度或节能运行。然而，日志中未见空调控制指令，且温度呈现不受控的上升趋势，这不符合正常热力学规律（除非有外部热源）。",
    "4. 排除误报：虽然 02:10-02:16 期间灯光有短暂开关动作，但这可能是自动感应或误触，不足以解释长达数小时的持续升温。考虑到住户为独居老人，无法及时应对突发火情，此情况风险极高。",
    "5. 结论：在无人员活动、无空调调节的情况下，室内温度持续显著升高，极有可能是由未熄灭的电器、线路短路或燃气泄漏引发的早期火灾征兆。"
  ],
  "key_evidence": [
    "00:30 - 04:15 期间所有房间运动传感器均为 0 (无人)",
    "客厅温度从 22.84°C 持续上升至 24.19°C，厨房温度同步升至 23.78°C",
    "期间无任何空调制冷/制热控制指令记录",
    "温度上升速率和幅度远超自然散热波动范围"
  ],
  "recommended_actions": [
    "立即远程通知家属或紧急联系人，告知家中可能存在火情隐患。",
    "若系统支持，尝试远程强制关闭客厅及厨房的所有非必要电源插座（需确认协议权限）。",
    "检查并重置烟雾报警器状态，确保其处于待命状态。",
    "建议用户到家后第一时间检查厨房灶具、取暖设备及电路，排查起火源。"

## 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
{

  "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 1: 分析时间与环境背景。日志显示时间为 2026-08-05 的凌晨 00:10 至 04:15，住户为独居老人，此时段通常为睡眠或无人在家状态。",
    "推理步骤 2: 识别温度异常模式。从 00:10 到 04:15，客厅温度传感器读数从 22.67°C (2267mK) 持续攀升至 24.07°C (2407mK)，并在短时间内（约 3 小时内）上升了超过 1.4°C。这种在无人状态下持续、单向的高温上升趋势不符合正常环境热力学规律（通常夜间会因散热而缓慢下降或持平）。",
    "推理步骤 3: 结合 occupancy 数据排除误报。在此期间（特别是 00:30, 01:30, 02:00, 02:30, 03:00, 03:30, 04:00），所有房间的运动传感器均报告 Occupancy = 0，确认屋内无人。同时，厨房温度也同步升高（最高达 23.76°C），排除了单一设备故障的可能性，指向热源泄漏或火灾初期征兆。",
    "推理步骤 4: 关联设备行为。虽然灯光有短暂开关记录（02:10-02:16），但不足以解释长达数小时的持续升温。烟雾报警器未在日志中触发报警事件，可能处于未激活状态或尚未达到阈值，但这不能抵消高温带来的高风险。"

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

  "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。

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：

  "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": "独居老人家中客厅温度在夜间无人状态下持续异常升高，且伴随空调关闭，存在严重的火灾隐患。",
  "reasoning": [
    "1. 环境状态分析：日志显示从 00:30 开始，所有房间（包括客厅、卧室、厨房）的运动传感器均报告 Occupancy = 0，表明整栋房屋处于完全无人状态。",
    "2. 异常模式识别：在无人居住的情况下，客厅温度传感器读数从凌晨 00:10 的 22.68°C (2268mK) 持续单调上升至 04:00 的 24.10°C (2410mK)，并在随后几小时内继续攀升至 23.94°C-24.04°C 区间（注意：Matter 协议中温度常以毫开尔文 mK 为单位，2400mK ≈ 20.85°C + 偏移量，此处需结合上下文判断趋势。若原始数据为摄氏度直接乘以 10 或类似缩放，则 2268 代表 22.68°C。假设单位为 mK，2268mK=19.53°C, 2410mK=20.95°C。即使按摄氏度理解，温差也显著）。更关键的证据是温度呈现**持续单向上升**趋势，而非随环境温度自然波动。",
    "3. 设备行为矛盾：虽然日志中未明确显示空调关闭事件，但通常夜间无人时空调应处于节能或关闭状态。然而，如果空调仍在运行且设定温度高于当前室温，或者空调故障导致制热/制冷失效，会导致室内温度异常。考虑到独居老人的背景，最可能的情况是：**空调被误设为加热模式且无人干预，或者空调系统故障导致热量积聚**。",
    "4. 风险推导：对于独居老人，夜间长时间无人看管且室内温度持续异常升高，极易引发火灾（如电器过热、线路老化加速）或导致老人因高温醒来后无法及时应对。这种‘无人 + 持续升温’的组合是典型的火险前兆。",
    "5. 排除其他因素：光照变化符合昼夜规律（凌晨关灯，白天开灯），无入侵迹象（门窗传感器未触发），无漏水迹象。核心问题在于热环境的失控。"

    "00:30 - 04:00 期间所有房间运动传感器连续报告 Occupancy = 0（无人状态）。",
    "living_room_temp_sensor 读数在无人状态下从 2268 持续上升至 2410（约 1.4 度以上的温升），且趋势未出现回落。",
    "该时间段内无任何人员活动记录，排除了人为热源（如做饭、取暖器使用）的可能性。"
  ],
  "recommended_actions": [
    "立即远程检查并重置客厅空调设置，确保其处于关闭或自动模式，避免持续加热。",
    "联系住户或其紧急联系人，确认老人安全及家中实际状况。",

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。

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",
  "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。

  "confidence": "medium",
  "threat_type": "behavioral_anomaly",
  "threat_description": "半夜反复开关同一盏灯",
  "reasoning": [

  ],

  "threat_description": "客厅温度传感器读数严重偏离物理常识，显示异常高温（约 230°C-240°C），且伴随无人的长时间持续升温，极可能是传感器故障或漂移导致的安全误报。",
  "reasoning": [
    "推理步骤 1: 分析时间与环境背景。日志时间为凌晨 00:30 至 08:28，此时独居老人应处于睡眠状态，所有房间运动传感器（occupancy）均报告为 0（无人），属于正常的夜间时段。",
    "推理步骤 2: 检查温度数据合理性。Matter 协议中温度通常以 0.01°C 为单位存储整数。日志中 `living_room_temp_sensor` 的 `MeasuredValue` 从 2286 (22.86°C) 开始，在无人情况下持续攀升至 2397 (23.97°C)，甚至后续出现类似 2300+ 的数值。虽然 23°C 本身是正常室温，但结合上下文需确认单位。若该设备配置错误将单位视为摄氏度而非十分之一摄氏度，则实际读数为 230°C+，这在室内绝对不可能发生。即使按 0.01°C 计算，从 22.86°C 到 23.97°C 在 8 小时内缓慢上升虽可能由空调故障引起，但考虑到卧室和厨房温度稳定在 22-23°C 左右，而客厅单独出现这种‘缓慢爬升’且数值极其规整的模式，更符合传感器校准漂移或固件 Bug 的特征。",
    "推理步骤 3: 关联其他传感器数据。同一时间段内，卧室、厨房的温度传感器读数稳定在 22.0°C - 23.5°C 之间，与客厅趋势不一致。如果客厅真的发生了火灾或极端加热事件，烟雾报警器（smoke_co_alarm）必然会在几分钟内触发报警，但日志中未出现任何烟雾报警事件。此外，灯光在凌晨 02:10 有短暂的开关动作（On->Off->On->Off），可能是老人起夜活动，但随后直到早上 08:28 才再次开灯，说明老人并未在客厅长时间停留，排除了人为开启大功率电器导致升温的可能性。",
    "推理步骤 4: 综合判断。在无人员活动、无火灾报警、其他房间温度正常的情况下，客厅温度传感器表现出异常的数值特征（疑似单位错误或严重漂移），这构成了一个高置信度的传感器故障/漂移风险。对于独居老人家庭，错误的温度读数可能导致自动空调系统失效或误导用户认为家中过热/过冷，进而引发健康风险或掩盖真实的火灾隐患。"
  ],
  "key_evidence": [
    "凌晨时段（00:30-08:28）所有房间 occupancy 均为 0，排除人为加热因素。",
    "客厅温度读数呈现非自然的线性爬升模式（2286 -> 2397），而其他房间温度稳定。",
    "同期无任何 smoke_co_alarm 触发记录，排除了真实火灾导致的升温。",
    "灯光行为显示老人仅在短暂起夜，未在客厅长时间逗留。"
  ],
  "recommended_actions": [
    "立即远程重置客厅温度传感器并检查其固件版本及配置参数（特别是温度单位设置）。",
    "安排技术人员上门更换客厅温度传感器，以防因读数错误导致老人对居住环境感知偏差。",
    "暂时调低客厅空调设定温度或关闭自动温控逻辑，防止基于错误数据做出危险决策。",
    "通知家属关注老人健康状况，确保夜间有人看护或增加巡视频次。"
