Description

I'd like control what's shown on the remote via API. That way I could change the active page depending on external events and context. Use cases that would be possible with this are for instance:

Automatically show the correct music device on my remote when I start playing music

I use various devices to start a music stream on connected speakers (google home, home assistant, spotify connect, ...). When music starts playing on e.g. my kitchen speaker, I'd like to make an API call to my RemoteTwo to show the kitchen speaker controls. That way I can just pick up the remote and play/pause or adjust volume regardless of how I initiated the music stream.

Change current UI page on the remote depending on which room I'm in

I'd like to switch the current R2 page from "Living Room" to the "Kitchen" page when I physically move the remote from room to room. I track bluetooth devices' location throughout my home with ESPs that lets me create location aware automations in home assistant. I could track the R2's bluetooth radio in this case and make an API call to the remote to switch page when its moved to another room.

Change (and lock down) the UI when the home is in guest mode

My home automation setup has a simplified and locked down mode when guest stay at my place. I'd like to trigger a change to show a different UI (or profile?) when the automation system is in guest mode.
