Open Vehicles has released OVMS, an open source platform enabling detailed remote monitoring, diagnostics, and control of electric vehicles. It supports live data, alerts, and customization, with integration options for home automation.
Open Vehicles has launched OVMS, an open source platform that allows electric vehicle owners and developers to remotely monitor, diagnose, and control their vehicles with extensive customization options. The system provides real-time data, alerts, and control capabilities, making it a significant development in EV telematics and personal vehicle management.
OVMS offers live monitoring of key vehicle metrics such as state of charge, temperatures, tyre pressures, and fault conditions. It supports push notifications for critical events like charge aborts, battery cell failures, or potential theft, enhancing vehicle security and maintenance. The platform enables control over functions like charging, climate, and engine tuning, depending on vehicle integration. It features scripting capabilities, allowing interfacing with external charge control systems and automation via MQTT, and supports data logging to SD cards and remote servers.
The system integrates into existing vehicle CAN buses, offering tools such as a configurable OBD2 translator, DBC decoder, CANopen client, and reverse engineering toolkit. OVMS also provides SSH access, WebSocket streaming, and CAN frame injection via TCP, making it a versatile tool for developers and enthusiasts alike. The platform is compatible with native Android and iOS apps for remote control and monitoring, emphasizing user control over data and regional restrictions.
Why It Matters
This development provides EV owners and developers with access to vehicle data and control options, which can support customization, diagnostics, and security features. As electric vehicles become more common, open source solutions like OVMS may influence industry practices, promote innovation, and support vehicle maintenance and safety. The ability to integrate with home automation systems also broadens the scope of EV management within smart home environments, appealing to users interested in connected technology.
