So, I have finally had the time to release the first non alfa version of my custom integration for Samsung Multiroom speakers. It should work for all Samsung Wireless Audio speakers and soundbars.
You can find it, and installation instructions on: Samsung Wireless Audio Integration
Hopefully it will be added to the HACS default list of integrations, but until then you will have to add it as a a custom repository.
I also hope that I soon have the time to share some experiences with these speakers (that I have have used for more than a decade) that I just love. The sound that you get from these speakers compared to the prices when they where available can’t be beaten by any other brand. Unfortunately they have never gotten any love or attention from Samsung, and therefore no firmware updates. A couple of years back they lost the ability to be used as Spotify Connect speakers, but then thanks to Spotify got it back. The last year I have also noticed that more and more radio stations on TuneIn where not possible to start playing on the speakers, which forced me to find the time to finish this integration. I play my favorite radio station on my speakers every day, all year around. And now I can continue this, even though Samsung seems to want me to scrap them and by new ones.
