Background
OVMS is part of a broader trend toward open source solutions in the automotive sector, particularly for electric vehicles. The platform builds on existing telematics and OBD2 diagnostics but distinguishes itself through extensive customization, scripting, and integration capabilities. Prior to this release, most EV telematics systems were proprietary, limiting user control and data privacy. The open source approach aims to fill this gap by providing accessible, configurable tools for a growing community of EV owners and developers.
