An app developed by ELEKS allows drivers to control their Tesla from their wrist through an Apple Watch set for release in April 2015.

Using your Apple Watch, you’ll be able to see your Tesla’s current battery status and available range, the state of climate controls in the car (and the ability to change them), and even the location of the vehicle. ELEKS’s Tesla watch app takes it a step further, letting you control certain functions, like locking and unlocking the doors, turning on the headlights, and making the car beep.
None of these features are unique to the Apple Watch; the Model S can already be controlled via a web-based application programming interface (API), and Tesla offers its own apps for iOS and Android. Tesla, of course, may eventually offer its own Apple Watch app to control the Model S, but the ELEKS app may beat them to the punch.
