ELGATO FLAGS HOW TO

Setup guide · Stream Deck + SimHub

Pitlane Flags

Race flags on every key of your Stream Deck. This guide takes about two minutes: install one free SimHub plugin, install Pitlane Flags, and you’re done.

What you need

  • SimHubFree, from simhubdash.com. Version 9.6 or newer.
  • Property ServerFree SimHub plugin by pre-martin. Lets other apps read SimHub data.
  • Stream DeckMK.2, XL or Mini, with the Stream Deck app 7.1 or newer.
  • A simLe Mans Ultimate, iRacing, ACC or any sim SimHub supports.
Pitlane Flags gets its flag data from SimHub through the Property Server plugin. Without it, the keys show SIMHUB OFFLINE.

Set up SimHub

01

Download PropertyServer.dll

Open the SimHub Property Server releases page. Under the newest release, open Assets and download PropertyServer.dll.

Don’t use the green “Code” button on the main page. You need the .dll file from Releases.
02

Copy it into the SimHub folder

Close SimHub first. Then copy PropertyServer.dll into the SimHub installation folder, the same folder as SimHubWPF.exe. By default that’s:

C:\Program Files (x86)\SimHub\

Start SimHub and enable the plugin

Start SimHub. It detects the new plugin and asks whether to enable it. Click Yes. If it doesn’t ask, go to Settings → Plugins and tick Property Server.

Accept the profile

Stream Deck asks to install the Pitlane Flags profile for your deck. Accept it. This is the page with a flag key on every button. You don’t need to open it; the plugin switches to it on its own.

Install profile?

The plugin Pitlane Flags would like to install the profile Pitlane Flags on your Stream Deck.

CancelInstall
Illustration · the profile name ends in XL or Mini on those decks
Only accept it once. If you ever see Pitlane Flags copy in your profile list, see Troubleshooting.

Test it

06

Run the demo

Select the Pitlane Flags profile in the Stream Deck app and press any key. All keys cycle through every flag. Press again to stop. Then switch back to your normal profile.

Before you’re in a session, the keys show one of these:

NO GAME
Connected, no sim running
SIMHUB
OFFLINE
Can’t reach SimHub
In session, no flag

Go racing

07

It runs in the background

Use your normal profile as usual. When a flag comes out, the deck switches to the flag profile and every key flashes that colour. About 1.5 seconds after the flag clears, it switches back to the profile you were on.

Press any key on the flag screen to dismiss it and go straight back. The deck won’t switch again for that same flag.

What each colour means

KeyFlagMeaning
CheckeredChequeredSession finished
Black / whiteBlackPenalty: pit or disqualification
OrangeMeatballCar damaged: pit for repairs
PinkPit limiterYour pit limiter is on
YellowYellowDanger ahead, no overtaking
BlueBlueFaster car behind, let it through
WhiteWhiteSlow car ahead (or last lap in some sims)
GreenGreenTrack clear, racing resumes (shown for 10 s)

If several are active, the one highest in this table wins. Which flags appear depends on the sim: not every sim sends every flag.

Extra keys

Find these under Pitlane Flags in the Stream Deck action list and drag them onto your normal profile.

YELLOW
Flag Status
AUTOON
Auto-Switch

Flag Status shows the current flag on one key, so you can see it without leaving your profile. It shows CLEAR when there’s no flag.

Auto-Switch turns the takeover on or off with one press, for example during qualifying.

Settings

Click any Pitlane Flags key in the Stream Deck app to open its settings. They apply to all Pitlane Flags keys.

Troubleshooting

ProblemFix
Keys show SIMHUB OFFLINECheck SimHub is running and Property Server is ticked in Settings → Plugins. Check the .dll is in the same folder as SimHubWPF.exe, then restart SimHub.
Keys show NO GAMENormal until a sim is running and SimHub detects it. Make sure the sim is selected in SimHub.
Deck never switchesCheck Background is ticked and the flag is selected under Switch on. Check the Auto-Switch key isn’t set to OFF.
One flag never appearsSome sims don’t send every flag. Le Mans Ultimate needs SimHub’s rFactor 2 shared memory plugin, which SimHub offers to install when you set up the game.
Pitlane Flags copy in your profilesDelete every Pitlane Flags profile, uninstall the plugin, install it again and accept the profile once.
SimHub on another PCSet SimHub host to that PC’s IP address and allow port 18082 through its firewall.
