Tessie: Tesla vehicle manager with watch and web controls
Tessie, from Tessie Technology LLC, is an iPhone app aimed at Tesla owners who want detailed vehicle management. The app logs trips, tracks battery health, and provides remote controls and automations accessible from phone, watch, and a web dashboard. It includes trip maps, energy and efficiency metrics, OBD-level diagnostics, Apple Watch key support, scheduling triggers, and real-time alerts. Casual drivers, data-minded owners, and fleet managers benefit from long-term analytics and multi-device control for daily driving and fleet oversight.
Tracks daily driving patterns and long-term battery trends
The app captures trip histories with maps, energy usage and efficiency metrics so owners see how individual drives affect long-term performance. It also reports battery health and degradation with comparisons to a broader Tesla fleet, giving context beyond single-trip summaries. For users who collect mileage or charging records, the log and visual timelines surface patterns that inform charging choices and maintenance planning.
Connects your car to watches, browsers, and smart home systems
Cross-device controls expand where you manage the vehicle, including native Apple Watch integration that can act as a Bluetooth key and a web dashboard for Mac or PC access. The app also links to Amazon Alexa, Google Home, and Home Assistant, and supports Android devices. The iPhone app requires iOS 15.0 or later, which is a setup consideration for owners on older phones.
Fits into daily routines through automations and timely alerts
Scheduling and triggers let the vehicle follow a routine, from climate preconditioning to charging reminders, and push alerts report driving events, charging state, Sentry Mode notices, and climate status. The automation engine supports complex "if-this-then-that" scenarios, so drivers who want hands-off routines can automate many tasks; owners who prefer minimal setup should expect an initial configuration period to tune those automations.
Keeps data under owner control while exposing technical diagnostics
Privacy controls give ownership and export options, with explicit export and deletion paths and standard OAuth authentication through Tesla’s site so credentials are not stored by the app. For technical users, a profiler exposes OBD-level diagnostics and real-time vehicle telemetry. The app also uses smart polling through official APIs to reduce unnecessary wake cycles and help limit phantom drain on the vehicle.
To sum up, Tessie is best for owners who want deep control and insights
To sum up, Tessie suits owners who invest time in configuring a device-centric workflow and who value long-form vehicle records and remote control from watches and browsers. Expect a learning curve to tune advanced automations and an account-gated tier to access full logging features. This tool rewards patient setup, making it a strong match for meticulous drivers and fleet coordinators rather than plug-and-play users.
