Tesvian delivers precision telemetry for Tesla owners and fleet operators: real-time battery degradation tracking, charge curve and vampire drain analysis, drive efficiency logs correlated with elevation, speed, and HVAC use, and location-based Sentry Mode automation. Cost reports simplify electricity expense tracking for taxes. Data is protected end-to-end with AES-256 encryption and retained in full. Polling starts at 5 seconds; the Plaid tier unlocks unlimited vehicles and 1-second sampling.
Every Tesla app I tried only showed me today's numbers. I wanted the full picture: how my battery is actually degrading, where the vampire drain is coming from, and what each charge session really costs. So I built Tesvian to poll vehicle data as often as every second, log drive efficiency against elevation, speed, and HVAC use, and automate Sentry Mode based on where I'm parked. Everything is encrypted end-to-end and kept in full, so nothing gets thrown away after a year. Would love to hear what you'd want tracked next.
