What Is Tessie?
Tessie is a third-party Tesla companion app built to offer more insights, control and automation than Tesla’s official app. Launched in 2021, Tessie now supports iOS, Android, Apple Watch, Android smartwatches, and web access.
It’s designed by Tesla owners, for Tesla owners, and it shows.
Key Features of Tessie
🔋 Battery Health Tracking
One of the biggest limitations of the official Tesla app is the lack of battery health visibility. Tessie solves this with real-world estimates based on your charging sessions and usage patterns. It’s a game-changer, especially for those buying or selling a used Tesla.
🧠 Automation
Automate routines like unlocking doors, pre-conditioning, or stopping charging at set times or conditions (e.g. when plugged in or departing home).
Want to auto-start Dog Mode or set your seat heaters before you leave? Tessie makes it easy.
📱 Smartwatch & Web Control
Control your Tesla from your smartwatch (including Android!) or desktop browser. Everything from window controls to Sentry Mode, all from your wrist or computer.
🧭 Detailed Trip Tracking
Track every journey in detail, including:
- Energy usage
- Driving efficiency
- Route heatmaps
- ICE vehicle savings comparison
- Telemetry from shared/lent vehicles
💸 Cost Analysis & Charge Monitoring
Track your phantom drain, charging sessions, and energy spend, broken down by kWh, charger type, and even cost estimates. If you’re using Octopus Energy’s Intelligent Go tariff, Tessie can help optimise your charging even further.
Why I Recommend Tessie
As a Tesla owner who also uses Octopus Intelligent Go, Tessie's insights into charging patterns, battery health, and smart home automation are unmatched.
The trip reports alone are worth the subscription if you’re a numbers nerd or want to prove your range!
