SimHub plugins: what exists and how to install them
Last updated · SimHub 9.11.22
SimHub plugins are .NET DLLs dropped into the SimHub install folder, which then appear as their own entry in the left menu after a restart and an enable prompt. There is no official plugin directory and no in-app marketplace, so discovery happens through Discord, the forum and GitHub. The most valuable thing to know about plugins is the warning: the official troubleshooting page names third-party plugins as the leading cause of SimHub instability, which makes disabling them the first diagnostic step for almost any problem.
SimHub also ships with bundled plugins that are disabled by default and that most people never discover. Those are covered at the bottom, and two of them are more useful than anything on the third-party list.
Read this before installing any of them
Third-party plugins are the number one cause of SimHub instability. That is the official troubleshooting page's own assessment, not ours. It has a practical consequence: when SimHub crashes, hangs, will not start, or behaves strangely, disable all plugins first and see whether the problem survives. This is a first step, not a last resort, and it costs nothing.
None of this means plugins are bad — several below are excellent and widely used. It means they run inside SimHub's process with SimHub's permissions, they are written by different people to different standards, and a fault in one is indistinguishable from a fault in SimHub until you disable it.
Install them one at a time, and give each a session before adding the next. Diagnosing five plugins added on the same evening is hard.
Installing, enabling and removing
Drop the DLL in the SimHub folder
The install directory, alongside SimHub.exe. Not a subfolder unless the plugin's own instructions say otherwise.
Unblock it if Windows marked it
Files downloaded from the internet carry a mark that stops .NET loading them. Right-click the DLL, choose Properties, and tick Unblock if the option is there. Miss this and the plugin silently does not appear.
Restart SimHub
Plugins are discovered at startup. There is no hot-load.
Confirm the enable prompt
SimHub asks whether to enable the newly found plugin. Say yes — declining here is a common reason a correctly installed plugin appears to do nothing.
Configure it from its own left-menu entry
Enabled plugins add themselves to the left menu. If it is not in the menu, it did not load.
To remove: Add/Remove features
Not by deleting the DLL, which leaves configuration behind. Use SimHub's own Add/Remove features screen.
The plugin directory
There is no official index, so this is one — assembled from repositories and community sources, with the source path given for each so you can verify rather than trust.
| Plugin | Source | What it adds |
|---|---|---|
| PostIt Note Racing | derrickmoeller/PostItNoteRacing | Extra computed properties for dashboards. Tested with iRacing. |
| Dahl Design Properties | andreasdahl1987/DahlDesignProperties | A large property library including fuel and strategy calculations. Documented at dahl-design.gitbook.io. |
| SimHub Property Server | pre-martin/SimHubPropertyServer | Exposes SimHub properties over TCP, so other software on the network can read them. |
| Stream Deck SimHub Plugin | pre-martin/StreamDeckSimHubPlugin | Stream Deck integration. Community-built — not an official Elgato or SimHub product. |
| MaIRA SimHub Plugin | herboldracing.com | iRacing data bridge. |
| Trueforce For All | Mhytee/Trueforce-For-All | Brings Logitech TrueForce haptics to games that do not support it natively. G923, G PRO and RS50. |
| FanaBridge | kelchm/FanaBridge | Fanatec bridge — rev and shift LEDs, button lighting, and the wheel display. |
| Tom's Car Setup Plugin | thogue95/Toms-Car-Setup-Plugin | Car setup data. |
| Daniel Newman Racing Plugin | danielnewmanracing.com | Lift and coast, plus LED settings. |
| NeoRed Plugin & Dashboard | NeoRed | Le Mans Ultimate focused, and auto-updating. |
| TruckSimulatorPlugin | community | Extras for Euro Truck Simulator 2 and American Truck Simulator. |
Two of these solve problems people pay money for. Trueforce For All brings Logitech's TrueForce haptics to games that never implemented it. Dahl Design Properties adds fuel and strategy calculations that would otherwise mean building formulas by hand. Both are free.
The bundled plugins most people never enable
SimHub ships with several plugins turned off by default. They are not third-party, they carry none of the instability risk above, and a couple of them are worth having.
- Control Mapper
- Aggregates several wheels and controllers into one virtual device, so games that cap simultaneous controllers stop being a problem. The most substantial bundled plugin by some margin — it has its own page.
- Custom Serial Devices
- Lets SimHub talk to hardware over a custom serial protocol rather than the standard firmware. The route for homemade devices that do not fit the wizard. Note it is capped at 10Hz without a licence.
- Keyboard Emulator
- Sends keystrokes in response to telemetry or events. Useful for triggering things in other software.
- Audio Control
- Audio playback driven by SimHub events.
- Shell Plugin
- Runs external commands on events.
- Joystick
- Joystick input handling. Worth knowing that its official wiki page is a TODO stub, so the software is ahead of its documentation here.
Enable them from Add/Remove features, which is the same screen used to remove third-party plugins.
Where to find plugins
There is no in-app marketplace, and this is the most common thing people are surprised by. Discovery is:
- Discord — the primary channel now that forum registration is paused for spam.
- The SimHub forum — readable and searchable without an account, and the archive is substantial.
- GitHub — searching for SimHub plugin repositories directly is often the fastest route, and it lets you see when a project was last touched.
- Creator sites — several plugins are distributed alongside a creator's dashboards rather than separately.
When evaluating one, check the last commit date. A plugin built against an older SimHub can break on an update, and an abandoned repository is a good predictor of a future problem.
Common questions
How do I install a SimHub plugin?
Drop the DLL into the SimHub install folder, unblock it in the file's Properties if Windows marked it as downloaded, restart SimHub, and confirm the enable prompt. It then appears as its own entry in the left menu. Remove plugins through Add/Remove features rather than by deleting the file.
Is there an official SimHub plugin directory?
No, and there is no in-app marketplace either. Discovery happens through Discord, the forum, GitHub and creator sites. That gap is why this page exists.
My plugin doesn't appear in SimHub after installing it.
Two usual causes. Windows marks files downloaded from the internet in a way that stops .NET loading them — right-click the DLL, open Properties, and tick Unblock. The other is declining the enable prompt SimHub shows on the next restart.
Can plugins break SimHub?
Yes, and the official troubleshooting page names third-party plugins as the leading cause of SimHub instability. They run inside SimHub's process, so a fault in one looks exactly like a fault in SimHub. Disabling all plugins is the first diagnostic step for almost any problem.
What plugins does SimHub come with?
Control Mapper, Custom Serial Devices, Keyboard Emulator, Audio Control, Shell Plugin and Joystick — all disabled by default and enabled from Add/Remove features. Control Mapper is the most substantial and solves a real problem with games that limit simultaneous controllers.
Is the Stream Deck SimHub plugin official?
No. It is a community project by pre-martin and is not an Elgato or SimHub product. It works well; it just is not officially supported, which matters when something breaks after an update.
How do I know if a plugin is still maintained?
Check the last commit date on its repository. Plugins built against older SimHub versions can break on updates, and an abandoned project is a reliable predictor of a future problem.
