-# PIGWay Device Agent v3.7.0
+<p><img src="docs/brand/pigway-logo.png" alt="PIGWay" width="96" height="96"></p>

-极轻的 Raspberry Pi / Linux 本地监控服务：CPU、内存、温度、磁盘、网络、服务/进程、系统健康告警与 journal 日志。无 Web 界面；无需硬件插件，也无需管理中心。
+# PIGWay Raspberry Pi Agent v3.11.4

-## 安装
+[简体中文](README.zh-CN.md) | English
+
+Disk discovery is manual: Device Console → System configuration → select the device → Storage settings → Scan disks. The inventory persists across restarts; known filesystem capacity updates weekly. Names and visibility belong to the Agent. See [deployment and validation](docs/STORAGE.md).
+
+
+PIGWay Raspberry Pi Agent is a lightweight local monitoring service for Raspberry Pi. It monitors CPU, memory, temperature, disk, networking, services, processes, system health alerts, and journal events. Ethernet monitoring reads the negotiated link speed and can alert when it remains below the configured minimum. It has no embedded Web UI and does not require a hardware plugin or Device Console.
+
+### Installation
+
+See the [Trixie fresh-install guide](docs/RASPBERRY_PI_OS_TRIXIE_FRESH_INSTALL.md) for Raspberry Pi OS Lite 64-bit based on Debian 13. The Agent itself does not access GPIO or I2C; OLED, RGB, and fan control belong to the independent hardware plugin.

 ```bash
 sudo ./install.sh
-# 显式启用 API：
+# Explicitly enable the API:
 sudo ./install.sh --enable-api
-# 不启用 API：
+# Keep the API disabled:
 sudo ./install.sh --disable-api
 ```

-交互安装询问是否启用远程 API，默认否；非交互安装未指定时也关闭。`--no-start` 仅更新文件和配置，不改变现有服务运行状态，接口开关在下次启动生效。
+Interactive installation asks whether to enable the remote API and defaults to no. Non-interactive installation also keeps it disabled unless explicitly enabled. `--no-start` only updates files and configuration; it does not change the current service state.

-配置文件：`/etc/pigway-pi-control.conf`。修改监控配置后执行：
+The configuration file is `/etc/pigway-pi-control.conf`. Restart the Agent after changing monitoring settings:

 ```bash
 sudo systemctl restart pigway-pi-control.service
 ```

-## 可选 API
+### Optional API

-默认 `[api] enabled = false`，没有网络监听。需要集中管理时改为 `true`，设置 bind/port，然后：
+The default is `[api] enabled = false`, with no network listener. To use centralized management, enable it and configure the bind address and port, then run:

 ```bash
 sudo systemctl enable --now pigway-pi-control-api.service
 sudo cat /etc/pigway-pi-control-api.token
 ```

-默认端口6001。读取及写入都需要 `Authorization: Bearer <token>`。令牌只用于该设备；安装器显示查询方法，不直接显示令牌内容。关闭 API：配置改为 false，执行 `sudo systemctl disable --now pigway-pi-control-api.service`。
+The default port is 6001. Every read and write request requires `Authorization: Bearer <token>`. The token belongs only to this device and is not printed directly by the installer. The API exposes health, status, logs, configuration, services, plugins, and plugin configuration under `/api/v1`. It does not serve a Web UI, register multiple machines, or proxy remote requests.

-API 提供 `/api/v1/health`、`/status`、`/logs`、`/config`、`/services`、`/plugins` 和 `/plugin/config`（均以 `/api/v1` 开头）。不提供网页、多机登记或远程转发。
+### Console and hardware plugins

-## 独立管理中心与插件
+- [PIGWay Device Console](https://tea.pigway.com/way/pigway-device-console) can run on a NAS or remote server for dashboards, configuration, and batch synchronization.
+- [PIGWay Yahboom Cooling HAT](https://tea.pigway.com/way/pigway-yahboom-cooling-hat) independently provides local telemetry, OLED, fan control, and RGB effects.

- [PIGWay Device Console](https://tea.pigway.com/way/pigway-device-console)：可部署在 NAS 或远端，登记设备地址与令牌，统一看板、配置和批量同步。
- [PIGWay Yahboom Cooling HAT](https://tea.pigway.com/way/pigway-yahboom-cooling-hat)：独立本地采集、OLED、风扇与 RGB。
+The remote API and local plugin integration are independent. After enabling plugin integration, register `yahboom-cooling-hat = /run/pigway-plugins/yahboom-cooling-hat/api.sock` under `[plugins]` and restart the Agent, or attach it through the Console. Discovery never binds a plugin automatically. Pausing or disconnecting integration does not stop the plugin's local functions.

-远程 API 与本地插件联动相互独立。插件启用接入后，可在 `[plugins]` 显式登记 `yahboom-cooling-hat = /run/pigway-plugins/yahboom-cooling-hat/api.sock` 并重启监控，或通过管理中心接入。发现不会自动绑定；暂停/断开联动不停止插件本地功能。
-
-## 运维
+### Operations

 ```bash
 sudo /usr/local/sbin/pigway-pi-control --diagnose
 sudo journalctl -u pigway-pi-control.service -f
 ```

-日志依照系统 journal 的保留策略，不额外建库。卸载任何一个项目不会卸载另外两个项目。插件协议见 [API v1](docs/HARDWARE_PLUGIN_API.md)。
+Logs follow the system journal retention policy; no additional database is created. Uninstalling one project never uninstalls either of the others. See [Plugin API v1](docs/HARDWARE_PLUGIN_API.md).
+
+## Naming and compatibility
+
+This project targets Raspberry Pi. Other Linux platforms are not covered by its support claim and may have separately maintained adapters. Repository naming does not change the existing `pigway-agent` adapter ID or `pigway-pi-control` service, configuration and API identifiers.

+
+## Compatibility
+
+PIGWay Raspberry Pi Agent v3.7.1 supports Raspberry Pi OS Lite 64-bit based on Debian 13 Trixie and Python 3.13. The Agent reads Linux `/proc`, `/sys`, systemd, network state, and journal data. It has no GPIO, I2C, Pillow, or third-party Python dependency and does not need a virtual environment.
+
+The Yahboom RGB Cooling HAT is an independent plugin. It uses Debian packages `python3-smbus2` and `python3-pil`, avoiding pip changes to the PEP 668 managed system Python. Its verified interface remains unchanged:
+
+- I2C bus `/dev/i2c-1`; I2C must be enabled. SPI is not required.
+- MCU `0x0D`; 128x32 SSD1306-compatible OLED `0x3C`.
+- The fan uses six levels through MCU register `0x08`. It is not a Raspberry Pi GPIO PWM fan and has no verified RPM feedback.
+- The plugin is the sole process owner of the MCU, OLED, RGB, and fan.
+
+Do not guess or change GPIO pins for this board. Other GPIO/PWM fans require their own driver.
+
+## Fresh installation
+
+Check the system first:
+
+```bash
+cat /etc/os-release
+python3 --version
+raspi-config nonint get_i2c
+ls -l /dev/i2c-1
+ss -ltnp
+```
+
+`raspi-config nonint get_i2c` must return `0`. Enabling I2C changes boot configuration and normally requires a reboot, so confirm SSH key access and stable power first:
+
+```bash
+sudo raspi-config nonint do_i2c 0
+sudo reboot
+```
+
+Install the Agent first. Its API is opt-in:
+
+```bash
+git clone https://tea.pigway.com/way/pigway-raspberry-pi-agent.git
+cd pigway-raspberry-pi-agent
+sudo ./install.sh --disable-api
+```
+
+To use Device Console, verify the port and explicitly enable the API:
+
+```bash
+sudo ./install.sh --enable-api
+sudo ss -ltnp | grep ':6001 '
+sudo cat /etc/pigway-pi-control-api.token
+```
+
+Install the hardware plugin after `/dev/i2c-1` is available:
+
+```bash
+git clone https://tea.pigway.com/way/pigway-yahboom-cooling-hat.git
+cd pigway-yahboom-cooling-hat
+sudo ./install.sh --enable-integration
+```
+
+Register its Unix socket under `[plugins]` in `/etc/pigway-pi-control.conf`, then restart only the Agent:
+
+```ini
+yahboom-cooling-hat = /run/pigway-plugins/yahboom-cooling-hat/api.sock
+```
+
+## Validation
+
+Validate both systemd services, Agent diagnostics, boot journal, and plugin status. Physically verify the four-line OLED and 10-second rotation, RGB alerts, and temperature-dependent fan levels. Plugin shutdown requests full fan speed and driver close never writes fan OFF. Since the board has no tachometer feedback, requested level is not measured RPM.
+
+The Agent API is disabled by default and the plugin uses a local Unix socket, so the default installation opens no TCP port and does not conflict with Tailscale or an API gateway.

+
+[English](RASPBERRY_PI_OS_TRIXIE_FRESH_INSTALL.md) | 简体中文
+
+## 兼容性结论
+
+PIGWay Raspberry Pi Agent v3.7.1 兼容 Raspberry Pi OS Lite 64-bit、Debian 13 Trixie 与 Python 3.13。Agent 只读取 Linux 的 `/proc`、`/sys`、systemd、网络状态和 journal，不依赖 GPIO、I²C、Pillow 或第三方 Python 包，也不需要 venv。
+
+Yahboom RGB Cooling HAT 已拆分为独立插件。插件使用 Debian 系统包 `python3-smbus2` 与 `python3-pil`，不会通过 pip 修改受 PEP 668 管理的系统 Python。硬件接口保持原实现：
+
+- I²C 总线：`/dev/i2c-1`，需要启用 I²C；不需要 SPI。
+- 控制 MCU：`0x0D`；OLED：`0x3C`，SSD1306 兼容 128×32。
+- 风扇通过 MCU 寄存器 `0x08` 的六档控制，不使用 Raspberry Pi GPIO PWM 引脚，也没有可验证的 RPM 反馈。
+- RGB 由 MCU 寄存器控制；插件是 MCU、OLED、RGB 与风扇的唯一进程所有者。
+
+因此不能把这块散热板当作直连 GPIO 风扇，也不应猜测或修改 GPIO 引脚。其他 GPIO/PWM 风扇需要独立驱动。
+
+## 安装前检查
+
+```bash
+cat /etc/os-release
+python3 --version
+raspi-config nonint get_i2c
+ls -l /dev/i2c-1
+ss -ltnp
+```
+
+`raspi-config nonint get_i2c` 返回 `0` 才表示 I²C 已启用。启用 I²C 会修改启动配置，并且通常需要重启；远程操作前应确认 SSH 公钥登录与供电稳定。
+
+```bash
+sudo raspi-config nonint do_i2c 0
+sudo reboot
+```
+
+重连后确认 `/dev/i2c-1` 存在。散热板插件安装器会安装诊断工具并检查 `0x0D`、`0x3C`，不会改 SSH、网络或 Wi-Fi。
+
+## 安装顺序
+
+先安装通用监控 Agent：
+
+```bash
+git clone https://tea.pigway.com/way/pigway-raspberry-pi-agent.git
+cd pigway-raspberry-pi-agent
+sudo ./install.sh --disable-api
+```
+
+默认只监控 `ssh.service`，不会假定已安装向日葵或 Tailscale。需要 NAS 上的 Device Console 时，先确认端口未占用，再显式开启 API：
+
+```bash
+sudo ./install.sh --enable-api
+sudo ss -ltnp | grep ':6001 '
+sudo cat /etc/pigway-pi-control-api.token
+```
+
+再安装独立硬件插件：
+
+```bash
+git clone https://tea.pigway.com/way/pigway-yahboom-cooling-hat.git
+cd pigway-yahboom-cooling-hat
+sudo ./install.sh --enable-integration
+```
+
+最后在 `/etc/pigway-pi-control.conf` 的 `[plugins]` 中登记：
+
+```ini
+yahboom-cooling-hat = /run/pigway-plugins/yahboom-cooling-hat/api.sock
+```
+
+然后仅重启 Agent：
+
+```bash
+sudo systemctl restart pigway-pi-control.service
+```
+
+## 验收
+
+```bash
+systemctl --no-pager --full status pigway-pi-control.service
+systemctl --no-pager --full status pigway-cooling-hat.service
+sudo /usr/local/sbin/pigway-pi-control --diagnose
+sudo journalctl -u pigway-pi-control.service -b --no-pager
+sudo journalctl -u pigway-cooling-hat.service -b --no-pager
+curl --unix-socket /run/pigway-plugins/yahboom-cooling-hat/api.sock http://localhost/v1/status
+```
+
+实机还需肉眼确认 OLED 四行主页与10秒轮播、RGB 告警颜色/效果，并通过温度变化确认风扇档位。停止插件时会请求风扇全速，驱动关闭时不会写风扇 OFF；硬件无转速反馈，因此只能确认请求档位，不能声称测得真实 RPM。
+
+API 默认关闭，不占用 TCP 端口。插件只使用本机 Unix socket，不会与 Tailscale 或 API 网关争用端口。两个服务都由 systemd 独立管理，异常退出自动重启，任一项目停止不会停止另一个项目。

+
+## 使用
+
+在 Console → 系统配置 → 选择设备 → 磁盘设置中点击“扫描磁盘”，显式发现新增磁盘。打开页面、普通刷新和重启不执行新增磁盘发现。扫描失败保留已有清单；不执行挂载、格式化或分区操作。
+
+已知磁盘容量每周刷新，CPU、内存与网络按自身周期采集。摘要显示实际采集时间；缺失指标不补零，采集失败不据此确认告警恢复。
+
+显示名称、同组顺序与隐藏偏好统一保存到 Console，首页与配置页共用；Agent 已有名称和隐藏定义作为默认值。隐藏只影响显示，不停止采集或删除历史。
+
+## Agent 行为
+
+认证接口 `PUT /api/v1/storage/scan` 读取块设备和挂载点，持久化清单到对应配置旁的 `.storage.json`。监控服务读取清单；新增磁盘须再次手动扫描。根分区指标保留兼容，服务重启可复用容量缓存，整机重启后的容量初始化不自动发现新磁盘。
+
+UUID 优先作为标识，其次为设备序列号和分区编号，再退回路径并标记 `stable_identity=false`。重复挂载及 loop/swap 等伪设备不展示；未挂载设备不伪造使用率。配置过的磁盘在扫描未发现时保留为断开状态。
+
+磁盘扫描不执行 SMART 或自检；SMART 能力以本项目的独立说明为准。
