Tesla Powerwall (Fleet API)

← PV, Battery, Grid, Meter

Tesla offers an official, but paid Fleet API. For private use, you can create a Tesla Developer Account at developer.tesla.com and receive a monthly API credit of $10.

The myteslamate.com guide explains the process and generates a free Access and Refresh Token. With this token pair and your Client ID created in the Tesla Developer Account, evcc can directly communicate with the Tesla Fleet API.

Supported features
