controlling the ryde thru the network

[Pa3fbx]

Hi all,
I know the quick tune can controll the ryde via network.
And tom's great remote controll app works also great.

But what message if any should i send if i would want to select a different preset.
The reason for this would be a posibility to user controll a ryde receiver to switch to a preset stream channel and go back to the original RF channel by the controller. I am using Node-red for my contoller witch has a web bases user page and this would give me a posibility to setup buttons to controll the 3 ryde receivers to multiple preset channels and fall back after sertain time.

I am goining to add some buttons to give users and administrators buttons to controll or restart the ryder app.
These command are normal via remotecontoll but that is unusable remotely because of stream delay.
so a need a few commands that controll direct functions...
