-# Pi Dashboard — ESP32-S3 RLCD 4.2" Project Plan
-
-## Goal
-
-WebSocket client on the ESP32-S3 RLCD board that receives system status from a
-Raspberry Pi home server over LAN and renders a monitoring dashboard via LVGL.
-
----
-
-## New project location
-
-Create a new ESP-IDF project directory **outside** the Examples folder, e.g.:
-
-```
-J:\dev\arduino\ESP32-S3-RLCD-4.2-main\Projects\pi_dashboard\
-```
-
----
-
-## Files to copy from the factory example
-
-Source root: `Example\ESP-IDF\10_FactoryProgram\`
-
-### Must copy (build skeleton)
-
-| File / Dir | Why |
-|---|---|
-| `CMakeLists.txt` | Project root cmake — edit project name, strip `EXTRA_COMPONENT_DIRS` if not using ExternLib |
-| `partitions.csv` | Partition table (8MB app partition, NVS, PHY) |
-| `sdkconfig.defaults` | Base config — **strip BT lines**, keep SPIRAM/flash/LVGL settings |
-| `main/CMakeLists.txt` | Main component registration |
-| `main/idf_component.yml` | Managed component deps — keep `lvgl/lvgl: ^8.4.0`, drop `avi_player` and `esp_new_jpeg`, **add `espressif/esp_websocket_client`** |
-
-### Must copy (display driver)
-
-| File | From | Why |
-|---|---|---|
-| `display_bsp.h` | `components/port_bsp/` | DisplayPort class — RLCD SPI driver with LUT pixel mapping |
-| `display_bsp.cpp` | `components/port_bsp/` | Full implementation: SPI init, reset, command sequences, SetPixel, Display |
-
-These two files are the entire RLCD hardware abstraction. No other display code
-exists. Copy them into a `components/display_bsp/` component in the new project.
-
-### Must copy (LVGL port)
-
-| File | From | Why |
-|---|---|---|
-| `lvgl_bsp.h` | `components/app_bsp/` | Lvgl_PortInit, Lvgl_lock/unlock declarations |
-| `lvgl_bsp.cpp` | `components/app_bsp/` | LVGL display driver registration, double-buffered PSRAM, tick timer, port task on Core 0 |
-
-Copy into a `components/lvgl_port/` component. This file is self-contained — its
-only dependency is `lvgl.h` and FreeRTOS.
-
-### Copy as reference (WiFi STA)
-
-| File | From | Why |
-|---|---|---|
-| `esp_wifi_bsp.h` | `Example/ESP-IDF/02_WIFI_STA/components/esp_wifi_bsp/` | Cleaner than the factory version — no scan-and-destroy, no BLE entanglement |
-| `esp_wifi_bsp.c` | same | Simple STA init + connect + reconnect skeleton |
-
-The `02_WIFI_STA` example is a better starting point than the factory program's
-wifi code. The factory version tears down WiFi for BLE scanning — useless for a
-persistent connection. You will need to modify the STA code to:
-- Make SSID/password configurable (NVS or Kconfig)
-- Add auto-reconnect on disconnect
-- Signal connection readiness via event group so the WebSocket task knows when to start
-
-### Do NOT copy
-
-| Component | Why not |
-|---|---|
-| `components/port_bsp/` (everything except display_bsp) | I2C bus, buttons, SD card, ADC, codec — none needed for a dashboard |
-| `components/ExternLib/` (SensorLib, codec_board) | Sensor drivers and audio codec — irrelevant |
-| `components/app_bsp/ble_scan_bsp.c` | BLE scanning — not needed, and conflicts with persistent WiFi |
-| `components/app_bsp/esp_wifi_bsp.c` | Factory version destroys WiFi for BLE — use 02_WIFI_STA instead |
-| `components/ui_bsp/` | NXP GUI Guider generated UI — you will design your own dashboard layout |
-| `components/user_app/` | Factory test logic — all replaced by your WebSocket + dashboard code |
-| `managed_components/` | Auto-downloaded by ESP-IDF component manager from `idf_component.yml` — never copy these |
-| `build/` | Build artifacts — never copy |

-### Boot sequence (app_main)
-
-1. `wifi_sta_init()` — start WiFi STA, wait for IP
-2. `RlcdPort.RLCD_Init()` — init display over SPI
-3. `Lvgl_PortInit(400, 300, flush_cb)` — init LVGL with double-buffered PSRAM
-4. Create initial dashboard UI (under LVGL lock)
-5. `ws_client_start("ws://<pi_ip>:<port>")` — connect WebSocket, register message handler
-6. app_main returns, FreeRTOS tasks take over
-
-### Data flow
-
-```
-Pi server --[WebSocket JSON]--> ESP32 ws_client
-  --> parse message
-  --> Lvgl_lock()
-  --> update lv_label / lv_bar / lv_table widgets
-  --> Lvgl_unlock()
-  --> LVGL port task flushes on next cycle
-  --> flush_cb converts 16-bit to 1-bit, pushes to RLCD

-- Collects system stats (psutil or /proc reads)
-- Serializes to JSON
-- Pushes to connected clients every N seconds

-## Key decisions still open
-
-1. **WiFi credentials** — hardcode for now, or Kconfig menuconfig, or NVS provisioning?
-2. **Dashboard layout** — what stats matter most? Single screen or multiple pages?
-3. **Update frequency** — how often should the Pi push? 2s? 5s? On-change?
-4. **Pi server location** — fixed IP or mDNS discovery?
-5. **Error states** — what to show when WiFi drops or Pi goes offline?

 ```
 
 The Pi runs a WebSocket server that pushes system stats (CPU, memory, disk, temperature, network, services) as JSON every 2 seconds. The ESP32 parses the JSON and updates LVGL widgets. A data staleness watchdog forces reconnection if the server goes silent.
 
+The display uses a two-column layout: left half shows Pi stats (CPU/RAM/DISK bars, CPU temp) and a services table; right half shows a large HH:MM:SS clock (montserrat_36), date with day-of-week, and local sensor readings (room temp, humidity). The services table auto-scrolls when services exceed the visible area; row height and visible row count are measured from LVGL at runtime, so the scroll loop adapts automatically to font, padding, or border changes. The clock updates every second from the on-board RTC, which syncs from the Pi's time when drift exceeds 60 seconds.

+# Pi Servers -- Roadmap
+
+## Docker Compose
+
+Containerize the pi servers for easier deployment.
+
+### Options
+
+1. **Single service** -- `run_all.py` as the entrypoint, both servers in one container
+2. **Split services** -- separate containers for `stats_server.py` and `contents_server.py`
+
+Single service is simpler. Split services allow independent scaling and restarts.
+
+### Configuration
+
+- Volume mount `assets/` and `config/alarms.json` so they're editable without rebuilding
+- Expose ports 8765 and 8766
+- Network mode `host` or a bridge with known IPs for ESP32 discovery
+- Restart policy: `unless-stopped`
+
+## Repository Extraction
+
+The `pi/` directory will become its own git repository.
+
+### Steps
+
+1. Extract `pi/` into a standalone repo with its own `README.md`, `requirements.txt`, and CI
+2. Add it back to this project as a git submodule
+3. The interface contract between the two repos is the WebSocket protocol -- JSON schemas and binary frame formats documented in `README.md`
+
+### Benefits
+
+- Independent versioning and release cycle
+- Pi-side contributors don't need the ESP-IDF toolchain
+- CI can test the Python servers in isolation
+- Cleaner separation of concerns between embedded firmware and host services

+# Pi Dashboard Servers
+
+WebSocket servers that feed system stats, alarm audio, and status images to the ESP32-S3 RLCD dashboard.
+
+## File Structure
+
+```
+pi/
+  run_all.py            # Launches both servers as child processes
+  stats_server.py       # Real system stats over WebSocket (port 8765)
+  contents_server.py    # Alarm audio + status images over WebSocket (port 8766)
+  mock_server.py        # Drop-in replacement for stats_server with random data
+  audio_handler.py      # WAV loading, PCM chunking, alarm streaming
+  image_handler.py      # PNG to 1-bit monochrome conversion, alpha compositing
+  alarm_scheduler.py    # Loads and validates alarm config, checks firing schedule
+  requirements.txt
+  config/
+    alarms.json         # Alarm schedule configuration
+  assets/
+    alarm/              # WAV files for alarm audio
+    img/                # Status images (idle.png, on_alarm.png)
+```
+
+## Requirements
+
+Python 3.10+
+
+```
+pip install -r requirements.txt
+```
+
+Dependencies: `websockets`, `psutil`, `Pillow`
+
+## Running
+
+Start both servers:
+
+```
+python run_all.py                        # both servers, default config
+python run_all.py --config path/to.json  # both servers, custom config
+```
+
+Or run individually:
+
+```
+python stats_server.py                       # port 8765 only
+python contents_server.py --config path/to.json  # port 8766, custom config
+python mock_server.py                        # port 8765, random data (no psutil needed)
+```
+
+## Servers
+
+### stats_server.py -- port 8765
+
+Pushes a JSON object every 2 seconds with real system metrics from `psutil`:
+
+- `cpu_pct`, `mem_pct`, `mem_used_mb`, `disk_pct`
+- `cpu_temp` (reads `/sys/class/thermal/` as fallback)
+- `uptime_hrs`, `net_rx_kbps`, `net_tx_kbps`
+- `services` (mocked until systemd integration)
+- `local_time` fields for RTC sync (`y`, `mo`, `d`, `h`, `m`, `s`)
+
+### contents_server.py -- port 8766
+
+Serves alarm audio and status images. Protocol:
+
+**Status image:**
+1. Text frame: `{"type":"status_image","width":120,"height":120}`
+2. Binary frame: 1-bit monochrome bitmap (1800 bytes)
+
+**Alarm audio:**
+1. Text frame: `{"type":"alarm_start","sample_rate":N,"channels":N,"bits":N}`
+2. Binary frames: raw PCM chunks (4096 bytes each, paced at ~90% real-time)
+3. Text frame: `{"type":"alarm_stop"}`
+
+Loads alarm config from `config/alarms.json` (override with `--config`). Checks schedule every 5 seconds, fires once per matched minute. If no config or empty config, sends idle image and blocks forever. On alarm: switches to alarm image, streams audio, switches back to idle.
+
+### mock_server.py -- port 8765
+
+Same JSON schema and 2-second push interval as `stats_server.py`, but all values are randomized. No `psutil` dependency -- useful for development on non-Pi machines.
+
+Does not include `local_time` fields.
+
+## Alarm Configuration
+
+Config file: `config/alarms.json` -- a single alarm object or an array of alarm objects.
+
+Example with two alarms:
+
+```json
+[
+  {
+    "alarm_time": "0730",
+    "alarm_days": ["Mon", "Tue", "Wed", "Thu", "Fri"],
+    "alarm_audio": "assets/alarm/alarm_test.wav",
+    "alarm_image": "assets/img/on_alarm.png"
+  },
+  {
+    "alarm_time": "2300",
+    "alarm_audio": "assets/alarm/sleep.wav",
+    "alarm_image": "assets/img/sleep.png"
+  }
+]
+```
+
+| Field | Type | Required | Description |
+|-------|------|----------|-------------|
+| `alarm_time` | `string` | Yes | 4-digit HHMM, 24-hour. Fires on the matched minute. |
+| `alarm_days` | `string[]` | No | 3-letter abbreviations: `Mon`–`Sun`. If omitted, fires every day. |
+| `alarm_dates` | `string[]` | No | `MM/DD` strings. Ignored if `alarm_days` is also set. |
+| `alarm_audio` | `string` | No | WAV path, relative to `pi/`. Default: `assets/alarm/alarm_test.wav`. |
+| `alarm_image` | `string` | No | Status PNG path, relative to `pi/`. Default: `assets/img/on_alarm.png`. |
+
+If both `alarm_days` and `alarm_dates` are present, `alarm_days` takes priority.
+
+## Modules
+
+### audio_handler.py
+
+- `find_wav(path=None)` -- uses the given path if it exists, otherwise falls back to glob in `assets/alarm/`
+- `read_wav(path)` -- reads WAV, returns `(pcm_bytes, sample_rate, channels, bits)`
+- `stream_alarm(ws, pcm, sr, ch, bits)` -- streams one alarm cycle over WebSocket
+
+### image_handler.py
+
+- `load_status_image(path)` -- loads PNG, composites transparency onto white, converts to 1-bit 120x120 monochrome bitmap (black=1, MSB-first)
+- `send_status_image(ws, img_bytes)` -- sends status image header + binary over WebSocket
+
+### alarm_scheduler.py
+
+- `load_config(path)` -- reads and validates alarm JSON; returns list of alarm dicts or `None`
+- `should_fire(config)` -- checks a single alarm entry against current local time
