This is overcome by events. I have completed a Soundbar Device Handler. See
I have a Samsung HW-MS650 soundbar which has WiFi capability and is controlled through the Samsung Multiroom App. Sadly, SmartThings does not support this new model in their native multiroom installation. So, I want to write my own device handler for basic control of the single device.
Current Status: Device Handler is almost complete. I can control the speaker functions and music playback control. Currently adding presets to allow selection of CP channels for playback. Current Expectations (based on experimentation):
Amazon Prime: from personal playlists (My Music)
TuneIn: one of the three presets
iHeartRadio: Songs in the favorites
Pandora: Songs from list on main page.
Spotify: NO SUPPORT. The Speaker can not control Spotify, Spotify can control the speaker.
When I get these done, I will do the first release for evaluation (beta stage). Hope to add:
Personal dlna players (i.e., local cloud storage, smartphones, computers/laptops).
