About

Unofficial Polestar is a Home Assistant integration that connects to Polestar's cloud to monitor and control a car. It adds battery data such as charge level, range and charging status, plus last known and last parked location, with real-time streaming for some of these. It can also start and stop climatization, lock and unlock the car, flash lights or honk, and open or close the windows. Charging settings, saved charge locations, scheduled climate timers, health warnings and software update information are covered as well. Each configuration entry handles one vehicle, and a polling interval can be set; a demo mode with a fake vehicle is available. Setup is done in the UI with a Polestar ID email and password, and some features are not available on every model.
