Created by three original Tesla Roadster owners in 2011, Open Vehicle Monitoring System (OVMS) is today on its 3rd iteration and is the leading open-source project for remotely monitoring and controlling electric vehicles via web interface or smartphone app.

We are the official source of OVMS hardware for North America. This OVMS v3 kit includes a SIM5360 3G module (US edition), OVMS data cable (US), and the OpenVehicles OVMS GSM antenna (US).

For 2.0-2.5 Roadsters, the K-Line expansion board enables TPMS integration. The board can be ordered separately or installed within an OVMS module.
