Teslog – Self-hosted Tesla telemetry

I started Teslog years ago as a free hosted beta. When Tesla introduced their streaming telemetry API, I needed to migrate away from polling to keep it cost-effective. At the time I didn't have the bandwidth for that, so I shut the project down.

Recently I used AI (Claude) to restart it and to replace the closed-source components from the original so I could open source it this time.

Features: real-time dashboard over WebSocket, drive logging with maps and efficiency stats, charge session tracking with cost calculation, battery health/degradation tracking, lifetime map, multi-vehicle support.

I also have an iOS companion app that I'll be open sourcing soon, but it is less of a priority.

Let me know if there's any questions.
