A streaming deck with OBS

Switch scenes, go live, record and see the stream timer, all from your phone. This uses the official OBS plugin.

You need: OBS Studio 28 or newer, the OBS plugin, and a paired device.

1. Enable OBS WebSocket

In OBS open Tools → WebSocket Server Settings, tick Enable WebSocket server, and set a password if you wish. Note the port (default 4455).

2. Install and connect the plugin

1. Build or download the OBS plugin (instructions).
2. In the editor: Plugins → Manage Plugins… → Install from Folder… and pick the plugin folder (the one with plugin.json).
3. Click the gear next to OBS: turn Enabled on, set the server (127.0.0.1 if OBS is on this PC), port and password, Save.
4. The status bar shows the connection. Click Refresh variables.

3. Scene buttons

For each scene add a Button. Text: the scene name. On Press add the OBS action to change scene and pick the scene from the list (filled from OBS itself).

Make the active scene stand out: add a dynamic Background rule, If obs.scene.current equal Game Then amber.

4. Go live

Add a button with the OBS toggle stream action and this text:

{obs.streaming|LIVE/OFFLINE} {obs.stream.duration}

Add dynamic rules: If obs.streaming equal true Then background red and animation Blink. Do the same for recording with obs.recording and {obs.record.duration}.

5. Audio

• A Toggle with the OBS mute actions for your microphone.
• A Slider with Min 0, Max 100 and the OBS volume action on Value changed. It uses the live dragged value.

6. Handy extras

• Dropped {obs.stream.frames.droppedPercent|0.0}% and FPS {obs.stats.fps|0} as labels.
• A button that shows or hides a scene item, or sets a text source (the text may contain {variables}).
• A Save replay button if you use the replay buffer.

Save and try it. If OBS is closed, the plugin waits and connects as soon as OBS starts.
