Hey community,
In the past weeks, I was able to develop an OpenHab 3 binding to control my Samsung Multiroom audio system. (R7 360 Bluetooth Multiroom Speaker - Ultimate Wireless Sound | Samsung UK). I know that this system is already some years old and deprecated by Samsung, but that is why I wanted to claim control over it. (It also took many years to get some insights on the used APIs to control them). But hey, better late than never 
The Addon is fully functional (use it daily and was tested on various samsung WAM devices). And it already supports the following features:
- Basic control (play, pause, stop) and volume control
- Start playing ‘presets’ defined in a speaker
- Retrieve information on what is playing, status, album information, groupname, …
- Play a custom MP3 from the internet on your speaker (image the possibilities
)
Grouped players can be controlled by controlling the first device of the group.
Use case: I currently control my group of speakers with a Zigbee based remote control.
The addon is not yet publicly available. Please drop me a message if you would like to test the latest version on your samsung speakers.
