Where Tessie Excels


Tessie is an excellent choice if you want a ready-to-use, polished experience without any setup or technical knowledge required.


Mobile Apps: Tessie offers native iOS and Android apps with a clean interface. You can check your vehicle status, send commands, and view history right from your phone.


Built-in Analytics: Trip history, charging statistics, battery health tracking, and—on Tessie Pro—Self-Driving usage statistics are included in the app. No additional hosting is required.


Ease of Use: Download the app, sign in with your Tesla account, and you're ready to go. Everything works out of the box with no configuration needed.


Lifetime Pricing: For those who prefer a one-time purchase, Tessie offers lifetime plans at $199.99 (Basic) or $299.99 (Pro).


Where Teslemetry Excels


Teslemetry is built for users who want maximum flexibility, first-party support, and integration capabilities.


First-Party Integrations: Unlike community-maintained integrations, Teslemetry writes and supports its own Home Assistant integration, Python SDK, and TypeScript SDK. This means direct support, faster updates, and consistent quality.


130+ Data Fields: Access over 130 telemetry data points including detailed battery cell data, thermal management, and granular vehicle state information.


Energy Products Support: Full support for Powerwall, Solar, and Wall Connector. Monitor your entire Tesla energy ecosystem in one place and build automations around energy production and consumption.


Developer-Friendly: First-party SDKs make it easy to build custom applications. Webhooks, REST APIs, Server-Sent Events, and comprehensive documentation support any development workflow.


OBS Streaming Overlays: Create professional streaming overlays showing real-time vehicle data for content creators.


Pay Only for What You Use: Teslemetry has no base or platform fee - you subscribe per vehicle or energy site, in your local currency.


Pricing Comparison


Teslemetry has no base fee and is priced per subscribed vehicle or energy site, with billing-cycle, currency, and tax-specific rates - see current pricing at teslemetry.com/pricing.


Tessie's published pricing (at the time of writing): $6.99/month or $69.99/year for one vehicle, with lifetime plans at $199.99-299.99. Check Tessie's site for their current rates.


Who Should Choose Which?


Choose Tessie if you:


  • Want a polished mobile app experience
  • Prefer built-in trip history and analytics
  • Want everything to work immediately with no setup
  • Prefer a lifetime purchase option
  • Want built-in Powerwall and Solar monitoring alongside your vehicle
  • Want hosted developer APIs without running your own Fleet API or Telemetry infrastructure


Choose Teslemetry if you:


  • Use Home Assistant and want first-party support
  • Have energy products (Powerwall, Solar, Wall Connector)
  • Want to build custom integrations or applications
  • Need access to 130+ detailed telemetry fields
  • Are a developer or content creator
  • Value direct support from integration maintainers



Both platforms use direct vehicle telemetry where the vehicle supports it and use other data methods for legacy cases. Your choice depends on whether you prioritize Tessie's ready-to-use apps and built-in analytics, or Teslemetry's first-party SDKs, Home Assistant support, Wall Connector support, and flexible integration tooling.
