Set up Moverlay.

From installer to a working overlay layout in a few minutes, plus the settings worth knowing and straight answers about data.

Install & update

Moverlay ships as one setup program, Moverlay-Setup-<version>.exe, containing the plugin, all 23 overlays and 2 dashboards, their picker images and the default configuration. You need a Windows PC with SimHub (9.12.6 or newer) and a supported game.

  1. Download and run the installer

    Get it from the download page. Setup locates SimHub from its uninstall registration; use Browse… if the folder shown isn't right.

  2. Choose Install

    If SimHub is open, setup offers to close it gracefully. Windows may ask for administrator permission when SimHub lives in a protected folder such as Program Files.

  3. Start SimHub and enable Moverlay

    Let setup restart SimHub, or start it yourself, and enable Moverlay when SimHub reports the new plugin (or later under Settings → Plugins).

“Windows protected your PC”

The installer isn't code-signed yet, so SmartScreen may warn on first run and the administrator prompt shows an unknown publisher. If you downloaded it from this site, choose More info → Run anyway.

Updating

Run the newer installer the same way. Before it changes anything, setup validates the package and backs up your installation to SimHub/PluginsData/Moverlay/Backups. An update keeps your configuration (labels, team colours, port), dashboard and screen ids, custom renderer URLs, bindings and saved overlay layouts with their placement. Installations from the MoverlayF1 era are migrated automatically.

Moverlay checks for a new version in the background when SimHub starts and shows a notice in its settings. It never downloads or runs an installer by itself.

Silent install

For unattended setups:

Moverlay-Setup-<version>.exe --silent --simhub "D:\SimHub" --log setup.log --start

SimHub setup

Moverlay reads the game through SimHub, so first make sure SimHub itself sees your game: turn on UDP telemetry in the game's telemetry settings as SimHub's game setup describes, then start a session and check that SimHub shows live data.

Overlays on top of the game

Every Moverlay overlay is its own SimHub dashboard named Moverlay - <Name>. In Dash Studio, add the ones you want to an overlay layout, position and size them over the game, and SimHub draws them transparent and click-through. Overlays you add later just join the same layout; existing ones keep their place across updates.

Dashboards on their own screen

  • Race Control Dashboard: select Moverlay - Race Control Dashboard for a spare monitor (1920 × 1080, or 2580 × 1080 ultrawide). Inside Moverlay's settings it is under Dashboards → Race Control.
  • Steering Wheel: assign it to your wheel's screen or a small 800 × 480 display in SimHub's device settings.

Show and hide from the wheel

Each overlay has a Toggle action and a Show for a moment action (fade in, hold, fade out) that you bind to a key or wheel button like any SimHub input, plus a switch for whether it is visible when SimHub starts. Several overlays can hide themselves in the garage.

Configuration basics

Everything is configured on the Moverlay page in SimHub's sidebar. Change what you like, then choose Save and apply.

TabWhat it holds
GeneralDriver display name, update channel, the local server address, and display defaults shared by every overlay (layout, text size, speed unit, rev lights).
OverlaysOne page per overlay, each with a live preview of unsaved changes.
DashboardsSteering Wheel and Race Control (pages, layouts, gadget zones).
Sound CommandsRace-engineer phrases as bindable actions, with Play and Test buttons.
AnalysisStart, Time Trial and Pit Stop: recorded sessions, export and Open in browser.
DiagnosticsA live view of recent plugin logs, and the Share usage data switch.

Layout and text size

Every driving overlay has two layouts. Large, the default, keeps the two to four things you need at speed at a size that reads from the driving position. Compact is denser and shows more. Set the default and a shared text size (70–160 %) on General → Display, and override both per overlay.

Where things live

  • Configuration: SimHub/PluginsData/Moverlay/config.json. Updates preserve it; close SimHub before editing it by hand.
  • Local server: http://127.0.0.1:20777 by default. Change Port in the config file if that port is taken.
  • Analysis pages: /analysis/timetrial, /analysis/pitstops and /analysis/starts on that address, or use Open in browser on the Analysis tab.

Troubleshooting

The plugin appears but the overlays are blank

  • Make sure a session is running and the game's telemetry output is on.
  • On the Moverlay page, check that the overlay is enabled and visible.
  • Check whether a Toggle binding has switched it off.
  • For the Track Map, record or download the circuit with SimHub's own map feature if no local circuit is available yet.

The local renderer can't start

Another program is probably using port 20777. Change Port in config.json, restart SimHub and re-run setup so the standalone panels pick up the new port.

A phone or tablet can't open an overlay

That's by design: the renderer only listens on this PC's loopback address, so other devices can't reach it.

Privacy & data

Moverlay runs on your PC. Overlays, dashboards and analysis pages are served on 127.0.0.1 only, and recorded laps, pit stops and starts stay on your machine unless you export a file yourself. There are no accounts.

What the plugin sends to moverlay.com

Two small requests at SimHub start-up, from a background thread that never blocks SimHub or an overlay:

  • Update check: the plugin version and your release channel (stable or beta), nothing else.
  • Usage report, only while Share usage data is on: plugin version, a random installation id minted by the plugin, your driver display name if you set one, the SimHub and Windows versions, and which game you are playing.

No IP address, hardware id, e-mail or file path is sent, and the server does not store client addresses. The Share usage data switch sits below the log on the Diagnostics tab; turn it off and the report is never sent.

Shared laps are public

A future release adds sharing of the lap, pit-stop and start summaries the plugin records (not the full telemetry trace), controlled by the same switch. Everything shared is public: moverlay.com will show it with your driver display name, or “Anonymous” if you leave the name empty. Because there are no accounts, anonymous laps are grouped together, and a recording stays on moverlay.com after you delete it locally.

FAQ

Is Moverlay really free?

Yes. Every overlay, dashboard and analysis page is free, with no account and no paid tier.

Which games does it support?

EA SPORTS F1 23, F1 24, F1 25 and the F1 25 2026 Season Pack, in every game mode. iRacing and the Assetto Corsa family are planned. See Games & roadmap.

I run iRacing. Does anything work yet?

Not yet. iRacing is planned, not started: the plugin only reads EA SPORTS F1 telemetry today. With a game Moverlay has no adapter for, you get a “Waiting for … telemetry” message instead of cards full of zeros.

Will it cost me frame rate?

Moverlay reads the game once through SimHub and shares that work across every overlay. Update rates are bounded by what a display needs, unchanged values aren't redrawn, and hidden or idle overlays back off. Lap recording is measured at about half a microsecond per sample at 60 Hz, and you can lower the rate or turn it off.

Why does Windows warn about the installer?

The installer isn't code-signed yet. Choose More info → Run anyway if you downloaded it from moverlay.com.

Does it upload my laps?

Not today. Lap sharing arrives in a future release, only while Share usage data is on, and shared laps are public. See Privacy & data.

Is Moverlay official?

No. Moverlay is an unofficial community project, not affiliated with or endorsed by Formula 1, the FIA, EA, Codemasters, iRacing, Kunos Simulazioni or SimHub.
