Controlling your OBS Scenes with a Home Automation device

apead Home Automation, IOT

You can easily set up a standard 433 Mhz remote control that you use every day in your home to control scenes in OBS (Open Broadcast Software) if you don’t own a fancy Stream Deck.

All you need is a remote, a 433 Mhz Wifi Bridge and some Node-RED magic.

Sonoff 433 Mhz Bridge

Flash the bridge using these instructions: https://explorationspace.co.za/2021/02/10/sonoff-rf-bridge-433-tasmota/

Standard Home Automation Remote control
433 Mhz Wifi Bridge to OBS via Websockets Node-RED Flow

Install the OBS Websocket plugin: https://github.com/Palakis/obs-websocket/releases/tag/4.9.0

Node-RED Switch using button codes to control flow

The 433 Mhz Bridge when it detects a signal, it publishes a message with it’s contents via MQTT. These will have codes attached to them and in the case of a remote, that code / data that is sent via the message payload translates to the button pressed. You can “train” your solution with the remotes you have. These can be standard house-hold remotes.

Scene flows per button press

The switch statements routes the flow based on the button data to a specific function.

Scene switch command to OBS Socket Server

The function sends a message with the “scene-name” with the parameter of the scene created in OBS.
