SimHub

SimHub reads telemetry from most sim racing titles and turns it into dashboards, window overlays, LED strips, and motion/haptic effects through a large third-party plugin ecosystem. It is the tool most sim racers reach for first when they want a custom dash on a phone or tablet, shift lights on a strip, or bass-shaker rumble tied to curbs and gear changes.

SimHub's source is visible on GitHub but is not published under a standard open-source license. The core app is free; some plugins and hardware integrations (motion rigs, Arduino-based dashes) are sold as add-ons.

With SimLauncher: Already listed as a companion-app pill on the SimLauncher homepage; add it as a custom app slot to start it automatically with your sim.
