Telemetry Relay
Split your sim racing telemetry to every app and device at once.
Telemetry Relay solves a problem every serious sim rig runs into: your game broadcasts UDP telemetry to a single address, but a UDP port can only be claimed by one app on a machine — so SimHub, your wheelbase software, Stream Deck plugins, and remote dashboards all end up fighting over one feed. Telemetry Relay sits between your game and your tools, receives that stream once, and instantly fans out identical copies to as many destinations as you like — locally on different ports, or across your network to other PCs — all at the same time.
Built in Rust, it is a thin asynchronous pass-through that forwards packets byte-for-byte with negligible overhead, and it never modifies your telemetry. It runs quietly in the system tray, starts with Windows, and supports unlimited named destinations with per-destination rate limiting, multi-game profiles that auto-configure the right listen port, and a live packet inspector (F1) for confirming your setup or troubleshooting why an effect is not firing. Currently in public beta — free to download, with automatic in-app updates.
Use cases
Run all your tools at once
SimHub, wheelbase software, Stream Deck plugins and dash apps all get the same telemetry feed simultaneously — no more port conflicts.
Stream overlays on a second PC
Forward telemetry across your network so overlays and dashboards run on a different machine without touching game performance.
Debug your rig
The built-in packet inspector shows live telemetry, so you can confirm your setup or find out why an effect is not firing.
Frequently asked questions
A UDP port can only be claimed by one app, but your game broadcasts telemetry to a single address. Telemetry Relay receives that stream once and fans out identical copies to as many apps and devices as you like.
Never — it is a byte-for-byte pass-through built in Rust with negligible overhead. Your tools receive exactly what the game sent.
Multi-game profiles auto-configure the right listen port for F1 titles, Forza and other UDP-telemetry games — and you can add custom profiles for anything else.
Yes — the public beta is free to download, runs in the system tray, starts with Windows and updates itself automatically.
