## What is Pohjannaula?

Pohjannaula reads battery health, vehicle info, and trouble codes from Polestar 2 and Volvo CMA-platform vehicles over a wired OBD‑II Ethernet adapter. Everything runs on your device — no account, no servers, nothing sent to the cloud. Includes a Demo mode so you can explore the app without a car.

Requires a USB/OBD‑II-to-Ethernet (ENET) adapter for real vehicle use.

Pohjannaula is an independent tool and is not affiliated with, endorsed by, or sponsored by Polestar or Volvo.
