Open Vehicles has introduced OVMS, an open source system enabling EV owners to monitor, diagnose, and control their vehicles remotely via smartphones. The platform offers extensive data access, notifications, and control features, with ongoing development and community involvement.
Open Vehicles has launched OVMS, an open source platform that allows electric vehicle owners to remotely monitor, diagnose, and control their vehicles through smartphones and web interfaces. This development offers a customizable, data-rich solution for EV enthusiasts and developers, emphasizing user control and privacy.
OVMS provides live monitoring of key vehicle metrics such as state of charge, temperatures, tyre pressures, and fault conditions. It features push notifications for critical events like charge aborts, battery cell failures, or potential theft, enhancing vehicle security and maintenance. The platform supports remote control functions, including charging, climate control, and engine tuning, depending on vehicle integration. It also offers scripting capabilities for interfacing with external systems, expanding its versatility. The system includes a web app, native Android and iOS apps, and integration with home automation via MQTT. Technical features include support for three CAN buses, CAN tools, a configurable OBD2 translator, a DBC decoder, SSH access, WebSocket streaming, and CAN frame injection via TCP. OVMS is designed to be regionally unrestricted, giving users control over their data and device customization, with ongoing community-driven development.
Why It Matters
This development matters because it empowers EV owners with greater control and insight into their vehicles, promoting transparency, customization, and security. The open source nature encourages community contributions and innovation, potentially accelerating EV technology adoption and integration. It also addresses privacy concerns by allowing users to manage their data independently of proprietary systems.
