Server v0.13.1

What's Changed

SBC / Cloud-Init Fixes

• SPI & I2C enabled via cloud-init bootcmd — All cloud-init templates (YAML, Python generator, TypeScript generator) now add dtparam=spi=on and dtparam=i2c_arm=on in a bootcmd block, so both interfaces are ready after the initial reboot without needing rt-setup.sh (#206)
• Fixed I2C config path on Bookworm+ — setup_ups() in rt-setup.sh now uses the /boot/firmware/config.txt fallback path (Bookworm moved it from /boot/config.txt), fixing silent I2C enable failures (#206)
• PiSugar soft shutdown enabled by default (#204)
• PiSugar RTC auto-sync for offline timekeeping (#198)
• Headless PiSugar install — Pre-seed debconf to avoid interactive prompts (#200)
• First-boot apt upgrade — Run apt update && apt upgrade on initial boot (#201)
• Official PiSugar installer — Switched to upstream install script (#197)
• UPS setup fixes — Fixed failures and config issues in rt-setup.sh (#195)

• Logs power-plug transitions (plugged/unplugged) to the forwarder_ups_events Postgres table
• Streams UPS status updates to the dashboard via SSE and to receivers via WebSocket fanout
• Sends initial UPS snapshots to newly connected receivers
• Dashboard UI displays battery percent, voltage, charging state, and temperature per forwarder
• SBC setup page updated with pisugar-server install and I2C configuration instructions

Receiver v0.17.0

What's New

PiSugar 3 Plus UPS Display (#192)

The receiver desktop app now displays UPS battery status for forwarders equipped with PiSugar 3 Plus HATs.

• Battery component in the Tauri UI showing percent, voltage, charging indicator, and temperature
• UPS state updates arrive via sentinel ReadEvents from the server WebSocket connection
• Automatic state pruning when a forwarder disconnects (clears stale battery info)
• Store-updater logic for managing per-forwarder UPS state lifecycle

Full Changelog: receiver-v0.16.0...receiver-v0.17.0

forwarder v0.9.0

What's New

PiSugar 3 Plus UPS Monitoring (#192)

Added optional UPS monitoring support for PiSugar 3 Plus battery HATs on Raspberry Pi forwarders. When enabled, the forwarder polls the pisugar-server TCP daemon and reports battery telemetry (percent, voltage, charging state, power plugged, temperature) to connected servers and receivers.

• New [ups] TOML config section to enable and configure UPS polling
• UPS status editing in the forwarder local web UI
• Integer-based telemetry (millivolts, centi-degrees) with change-detection to minimize noise
• Three-state availability model: unavailable → available → stale
• Transition-only warning logs for power-plug state changes

Forwarder v0.11.1

What's Changed

E-ink Display Improvements

• "Powered Off" message on shutdown — After the forwarder shuts down, a centered "Powered Off" message is rendered on the e-ink display with a full refresh before the display sleeps. Since e-ink retains its last image without power, this text remains visible while the device is off. (#207)
• Landscape orientation fix — Display rotated 90° CCW for correct landscape orientation (#205)
• GPIO access fix — Allow gpiochip0 access in container permissions and improved SPI configuration hint (#203)

Full Changelog: forwarder-v0.11.0...forwarder-v0.11.1

forwarder v0.11.0

What's New

E-Ink Display Support

• New: Waveshare 2.13" e-ink display module — shows forwarder status (connection state, reader info, chip read counts) directly on the SBC hardware via SPI/GPIO (#191)
• Fixed rppal HAL feature flag for embedded-hal 1.0 compatibility (#196)
• Improved e-ink logging for easier debugging of display failures (#202)

SBC Deployment Improvements

• Enable SPI in boot config automatically for e-ink display (#199)
• Enable PiSugar RTC auto-sync for reliable offline timekeeping (#198)
• Run apt update && upgrade on first boot for security patches (#201)
• Pre-seed debconf for fully headless PiSugar install (#200)
• Use official PiSugar installer script for UPS setup (#197)

Forwarder v0.10.1

Bug Fixes

E-Ink Display Hardware Compatibility (#196)

Fixed two issues that prevented the e-ink display feature from compiling on ARM targets (the actual hardware):

• Missing hal feature on rppal: Without the hal feature flag, rppal::hal::Delay doesn't exist and GPIO/SPI types don't implement the embedded-hal 1.0 traits required by epd-waveshare. Added features = ["hal"] and wrapped Spi in SimpleHalSpiDevice since rppal's Spi doesn't directly implement embedded_hal::spi::SpiDevice.

• Color vs BinaryColor type mismatch: The epd-waveshare Display2in13 uses epd_waveshare::color::Color as its DrawTarget::Color type, not embedded_graphics::pixelcolor::BinaryColor. Used the color_converted() adapter from embedded-graphics to bridge the two types in the forwarder's e-ink draw closure.

Full Changelog: forwarder-v0.10.0...forwarder-v0.10.1

Forwarder v0.10.0

What's New

E-Ink Display Support (#191)

Added support for the Waveshare 2.13" e-ink display HAT (250×122px), giving forwarders a local status screen without needing a monitor.

• New rt-eink crate with a two-column layout engine, embedded-graphics renderer, and epd-waveshare hardware driver
• Integrates via tokio::sync::watch — StatusServer publishes DisplayState on every mutation, and the e-ink task redraws with a hybrid partial/full refresh strategy
• Desktop simulator available: cargo run -p rt-eink --example eink_sim --features simulator
• --eink-sim flag added to dev.py for launching the simulator alongside the dev environment
• Deployment updates: systemd service gets SPI/GPIO group access, rt-setup.sh auto-detects SPI and generates [eink] config section

Deployment Fix (#195)

• Fixed UPS setup failures and config generation in rt-setup.sh

Full Changelog: forwarder-v0.9.0...forwarder-v0.10.0

Server v0.12.0

New Features

• Reader control via WS proxy: Added a WebSocket proxy layer that lets receivers send reader control commands (clock sync, read mode, TTO, recording, download, etc.) through the server to forwarders — no direct receiver-to-forwarder connection needed (#186)
• Sentinel tunneling: Server now tunnels ReaderInfoUpdate and ReaderDownloadProgress events from forwarders to connected receivers in real time, enabling live feedback for reader operations
• Reader control UI: New ReaderControlPanel card on the server stream detail page (above epoch mapping) using a shared Svelte component from shared-ui

rt-protocol

• 4 new structs: ReceiverProxyReaderControlRequest, ReceiverProxyReaderControlResponse, ReceiverReaderInfoUpdate, ReceiverReaderDownloadProgress
• 4 new WsMessage variants for the proxy/tunneling protocol
• 2 sentinel constants for reader info/download progress routing

Changed Files

• services/server/src/ws_receiver.rs — WS handler for proxied reader control requests + sentinel tunneling logic (+267 lines)
• services/server/src/ws_forwarder.rs — forwarder-side proxy relay (+104 lines)
• crates/rt-protocol/src/lib.rs — new protocol types and message variants
• apps/server-ui/src/routes/streams/[streamId]/+page.svelte — reader control card integration
• apps/shared-ui/src/components/ReaderControlPanel.svelte — shared reader control panel component

Full Changelog: server-v0.11.1...server-v0.12.0

Receiver v0.16.0

New Features

• Admin clear-data action: New "Clear Data" button in the Admin tab that wipes subscriptions, cursors, earliest epochs, receiver mode, and DBF config while preserving server URL, token, and receiver ID — a middle ground between full factory reset and manual cleanup (#188)
  • Uses a database transaction to atomically reset non-profile fields and delete operational tables
  • Two-step confirmation UI placed between "Reset Profile" and "Factory Reset" buttons

Bug Fixes

• Stream metrics on initial load: Fixed "Metrics unavailable" showing when first opening the receiver until unsubscribing/resubscribing — initial metrics sent during the WS handshake were lost because Svelte event listeners weren't registered yet (#189)
  • Stream metrics are now cached in the receiver backend (AppState) and exposed via a new get_stream_metrics Tauri command, fetched during loadAll() alongside other startup data
  • Cache is cleared on disconnect to stay consistent with the frontend
• Vite dev server binding: Fixed Tauri dev server hanging by explicitly binding Vite to 127.0.0.1 instead of localhost (which may resolve to ::1 on IPv6 systems)

Receiver Backend

• New clear_data() DB method with transactional reset of operational state
• New get_stream_metrics control API endpoint + Tauri command for cached metrics
• Session handling updated to cache metrics in AppState on receipt

Receiver UI

• Admin tab: new two-step "Clear Data" confirmation button
• Stream metrics loaded eagerly on startup via loadAll()
• Store updated with metrics caching and clear-data state management
