Changelog

Capability updates as they ship. Newest first.

2026.03.23
PROFILES

Vehicle and device capability profile system. Signal catalog, device type registry, and data-driven capabilities page.

Global signal catalog (37 signals), device type profiles (G-Series), vehicle model signals (Infiniti Q50). Public capabilities page at /site/capabilities shows confirmed data points per device + vehicle combo. Profiles grow automatically as devices discover and confirm new signals.

2026.03.22
OBD

Nissan Mode 22 fuel level confirmed. Diagnostic session init, auto-discovery pipeline, global PID profile table.

PID 1166 returns accurate fuel level on Q50 (A/1.6 equation, session 0xC0). Three candidate PIDs tried automatically on connect. First responder stored to obd_pid_profiles for all future Q50 devices.

POWER

ACC bounce debounce. Wake lock retention across IGN transitions. Immediate flush on ignition-off.

2-second debounce prevents MCU relay bounce from killing the service. Wake locks held in MEDIUM/HIGH modes. Trips and telemetry flushed within 24-second MCU shutdown window.

TRIPS

Trip tracking race condition fixed. Async createTrip guard prevents distance accumulator reset.

Added tripCreating flag to prevent multiple startTrip calls while network request is in flight. Orphaned trips from March 21 recovered with GPS-derived distances.

DEVICES

Device deduplication. Stale device records merged and cleaned. Dashboard now shows correct active device.

APK re-signing changed ANDROID_ID, creating duplicate device records. Historical data migrated to active device IDs. 5 devices consolidated to 2.

TELEMETRY

Fuel level bug fixed. Throttle was mapped to fuel_pct column. CAN fuel event handler added.

Copy-paste bug in SupabaseClient mapped throttle_pct to fuel_pct. OBD PID 0x2F not supported by Q50. CAN_CAR_FUEL_EVT handler added to CanBusReceiver.
