Hey Product Hunt! 👋 I built Zolt out of a personal frustration: existing companion apps were either clunky, placed a noticeable drain on phantom battery by constantly waking the car, or lagged behind on real-time data. Zolt connects directly to the official Tesla Fleet API to stream 170+ real-time vehicle parameters with ultra-low latency. What you can do with Zolt: Live Telemetry: Monitor real-time speed, power output/regen, battery temps, and cabin climate dynamics on an interactive dashboard. Charging Analytics & Cost Tracking: Log charge sessions accurately, track kWh usage, and calculate real costs. Battery Health & Degradation: Keep tabs on true pack capacity and range trends over time without unnecessary vehicle polling. Lightweight & Battery Safe: Built to read streamed fleet telemetry efficiently without keeping the car's MCU awake 24/7. I’d love to hear your feedback on the dashboard layout, data responsiveness, and what specific telemetry visualizations or integrations you'd like to see next!
