OBS Studio

SAMMI communicates with OBS via OBS Websocket (OBSWS), which allows you to remotely control and listen to OBS Studio events.

Install OBS Websocket #

SAMMI is now compatible with OBS websocket 5.0. As this version is still very new, please note that some of your extensions might not work with it until they have been updated.

OBS Studio 28 comes bundled with OBS Websocket 5.0. There is no need to download a separate plugin for it.

To ensure the 4.x version protocol is still supported, you can download the 4.9.1-compat plugin for OBS Studio 28 available at the link below.


Connect SAMMI to OBS Websocket #

Once you have downloaded and installed OBS Websocket, you can proceed with connecting it to SAMMI in a few easy steps.

In your SAMMI click on OBS Connections at the bottom menu:

  • Name: Name of your OBS. The first OBS will always be Main and cannot be changed.
  • Protocol: Choose the protocol your OBS Websocket is using.
  • IP: IP Address of the OBS Websocket. Unless you’re connecting to an OBS on another computer, it will be always 127.0.0.1.
  • Port: Port of the OBS Websocket. Must match the port in your OBS-Tools-Websocket Server Settings.
  • Password: Password to authorize with OBS Websocket. Leave empty, unless you checked Enable Authorization in OBS-Tools-Websocket Server Settings. In that case the passwords must match.
  • Auto Connect: Whether you want SAMMI to automatically connect to OBS Websocket on launch
  • Non-Blocking: Leave unchecked unless you have difficulties connecting to OBS Websocket.
  • Fetch OBS Data: Whether you want to fetch OBS Data (such as current scenes and their items) from this particular OBS Websocket connection.

Once you press connect, you should see a yellow notification message OBS [Main Connected] and the status indicator for Main OBS in the left bottom corner should change from red to green.

Connect SAMMI to multiple OBS Websockets #

You can connect SAMMI to multiple OBS Websockets, just add another connection in your OBS Connections settings.
You will need to manually select your OBS Name for all your OBS commands (if not using Main OBS connection), so SAMMI knows which OBS to send them to. OBS Name accepts variables as inserts as well.

Permanent Variables
Once you’re connected to OBS Websocket, SAMMI provides you with some useful permanent variables that you can use in your commands.
All OBS variables are saved in global.[obsName] object.
If you’re using only one single OBS connection, your variables will be always saved in global.Main, for example global.Main.connected.

Variable Explanation
global.[obsName].connected Whether you’re connected to your selected OBS Name, 1 = connected, 0 = not connected
global.[obsName].current_scene Your selected OBS current scene
global.[obsName].previous_scene Your selected OBS previous scene

Listen to OBS events in SAMMI #

You can trigger buttons in your SAMMI by listening to events in your OBS Studio, such as switching to a new scene or enabling a studio mode.
You can find a detailed guide to setting up your OBS triggers in our Triggers-OBS section.
