WebSocket telemetry stream + mobile UI + alerts
sl-jetson added 1 commit 2026-03-04 23:34:06 -05:00
Implement WebSocket telemetry relay with:
- 2Hz JSON aggregation (battery, motors, IMU, GPS, health, social)
- Port 9091 with token authentication
- msgpack compression option
- 5-minute circular history buffer
- Mobile-friendly responsive HTML UI
- Auto-reconnect WebSocket with fallback
- Critical alerts: low battery (< 15%), high temps, node crash
- Real-time dashboard with telemetry gauges

Features:
- Battery monitoring with SOC/voltage/current
- Motor command visualization (L/R duty)
- IMU attitude display (roll/pitch/yaw)
- CPU/GPU temperature with thresholds
- RAM/Disk usage progress bars
- GPS coordinates (lat/lon/alt)
- Social state (speaking, face tracking)
- Alert history with severity levels
