Landmark Desktop

Landmark Desktop

A small Windows app for the parts of Landmark that need your PC: your dock floating over a fullscreen game, viewer effects on your real screen, a real camera device for OBS, and plugs, lights and boards that react to tips. Everything else stays on the dashboard, which the app opens in its own window.

Install and connect

  1. Download it from Landmark Desktop in the dashboard and run the installer. Windows may say it protected your PC because the app is not signed yet. Click More info, then Run anyway.
  2. The app opens on your dashboard. Sign in if you are not already.
  3. On the Landmark Desktop page, click Connect. An Authorize button appears in a small window inside the app. Click it once. That is the whole setup.

The app updates itself. You can sign out any computer from the same page, from any browser.

What the app adds

Overlay over your game

The control panel (chat, TTS, your deck) docks to an edge of the screen you pick and stays on top of a borderless fullscreen game. Ctrl+Alt+L shows and hides it. Display Capture in OBS never sees it, so you run the show with nothing visible to viewers. For games in exclusive fullscreen the app can draw the panel inside the game itself. Both are switched on from Screen FX.

Screen FX

Viewer-paid effects land on your actual monitor: tomatoes, jumpscares, a captcha you have to solve live, an AI pop-up ad. You choose the monitor and whether viewers see each layer. Prices are yours. See Screen FX.

Landmark Camera device

Your restyled camera shows up as a normal camera called Landmark Camera in OBS, Zoom and Discord. One click on Camera settings registers the device with Windows (it asks for admin once). The window-capture route still works if you prefer it.

Smart plugs, lights and boards

A tip fires the water gun. A sub starts the bubble machine. A raid turns the room red. The app talks to the hardware on your own Wi-Fi and the addresses never leave your PC. Supported out of the box:

  • TP-Link Kasa plugs and bulbs (found automatically)
  • LIFX bulbs (one cloud token, then pick lights from a list)
  • WLED light strips
  • Shelly relays and bulbs
  • Tasmota plugs and bulbs
  • Any ESP32 or Raspberry Pi running the Landmark sketch (below)

On Smart plugs & lights inside the app, click Find devices. Everything that answers on your network shows up. Add it, hit Test, then make a control: pick the device, choose on or off with a flip-back time, and bind it to a tip amount, a sub, a follow, bits, a redeem or a chat command.

The Landmark device protocol

Any board that can serve two HTTP routes works with Find devices. Ready-made sketches for an ESP32 (Arduino) and a Raspberry Pi (Python, nothing to install) are on the Setup tab of Smart plugs & lights. If you want to write your own:

GET  /landmark/ping
  -> 200  {"ok": true, "name": "Water gun"}

POST /landmark/state          (JSON body)
  {"power": "on" | "off" | "toggle",
   "brightness": 0-100,                    optional
   "color": {"h": 0-360, "s": 0-100, "k": 1500-9000}}   optional
  -> 200  {"ok": true}

The app only ever sends what you set on the control. Nothing a viewer types reaches the board. The device address has to be a private LAN address (192.168.x, 10.x, 172.16 to 172.31), and the app never follows redirects from it.

Where the settings live

There is no separate settings window. The Landmark Desktop page in the app shows whether this PC is connected and the live state of each feature, with Discord status, start-with-Windows and updates under App settings. Devices, controls and prices are edited on their own pages, the same ones you use in a browser.
