Issuing Flex Radio API Commands from Streamdeck and Node Red

Use Case

As a Flex Radio user I want to issue Flex Radio API commands from my Streamdeck console. I also want the same functions available on the Node Red console.

Solution Overview

I am doing direct API calls to the Flex Radio from Node Red. Pressing the Streamdeck buttons initiates the NodeRed fucntion.  We look at some simple examples below.

In Node Red, node-red-contrib-streamdeck-ws  needs to be installed from the pallette and a web socket needs to be set up to 'listen' for the Streamdeck. The Node Red screenshot below:

The constituent functions in the above flow are set up as follows:

The Link Out nodes in the above flow go to the relevant function per the key press. Lets look at some examples. In these examples I have three Streamdeck buttons (we'll come onto those later). One to listen to Slice A but mute Slice B, one to listen to Slice B but mute Slice A and one to listen to both slices. I found I had to put some delays in the work-flow, you can experiment with this.

Each of the functions contains the API command. An example is below:

It is also possible to send messages from NodeRed back to Streamdeck, for example you may wish to change the colour of a button when it has been pressed. I found I could get this working but it introduced unacceptable delays to the workflow i.e. I pressed the button and then had to wait for it to change colour. Anyway, to send an image back to the Streamdeck button - info will be here soon.
