TeslaLogger records everything your Tesla or Lucid Air does and stores it on hardware in your own home, building a private history no subscription service controls. Trips are logged with consumption and efficiency, charging sessions capture curves and history, and battery degradation and capacity are tracked over years of ownership. Grafana dashboards visualize consumption, trips, charging statistics, and battery health, and the admin panel's own dashboard can be customized for a quick glance. Public fleet statistics compare your degradation and charging curves against other owners, alongside firmware tracking and a map of fast charging sessions. Custom points of interest label the places your car visits, geofencing data organizes trips by location, and Supercharger invoices download automatically into a local folder. Existing histories import from TeslaFi or TeslaMate, so switching loggers does not erase years of records. A route planner link shares data with A Better Route Planner without handing your account to a third party or keeping the car awake. Eleven interface languages cover most households, and the same software runs in Docker, on a Synology NAS, or on a small Raspberry Pi beside the router, quietly logging through the official Fleet API permissions. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL 3.0 licensed.
