 Raspberry Pi 4B + 配套 128×32 OLED / 风扇 / RGB 散热扩展板的本机硬件监控 Agent。

 Pi 红色 PWR 灯关机后恢复硬件默认亮起的行为不强行修改，可作为“系统已关机但 UPS 仍供电”的直观提示。

+## v3.7.0 多机监控
+
+每台机器在 `[device]` 中设置稳定标识和显示名称；保留 `auto` 时读取本机 hostname。作为 Web 聚合入口的机器可在 `[hosts]` 中登记其他已安装 PIGWay Pi Control 的节点：
+
+```ini
+[device]
+identifier = living-room
+name = 客厅树莓派
+
+[hosts]
+study = http://192.168.1.20:6001
+nas-room = http://192.168.1.21:6001
+```
+
+未设置 `[hosts]` 时，API 和 Web 保持单机使用方式。聚合入口通过各节点现有 HTTP API 读取状态、journal 和配置；节点不可达时会在机器卡片上显示离线，不影响其他节点。
+
+新增接口：
+
+```text
+GET /api/v1/hosts
+PUT /api/v1/hosts
+GET /api/v1/fleet/status
+GET /api/v1/fleet/logs
+PUT /api/v1/fleet/config
+```
+
+运行状态按机器显示独立卡片，包括机器标识、hostname、型号、序列号、板卡版本、操作系统、内核、架构、CPU 核数和 Agent 版本。内存和根分区同时显示百分比、已用量、总量及可用/剩余量；Wi-Fi 以 0–100% 为主值，并保留原始 dBm。OLED 的 Wi-Fi 主值同样使用百分比。
+
+事件日志增加机器列、机器筛选和机器排序。系统配置可选择目标机器；批量同步只发送当前已修改的配置项，并逐台返回成功或失败结果。远端 Bearer Token 只保存在当前浏览器的 localStorage 中，不写入聚合机器配置文件。
