Hi
I’ve been trying - and failing - to discover exactly which Samsung Soundbars work with the SmartThings app. There’s a list of EVERYTHING it supports on the samsung site, but it is in no way searchable or configurable.
Does such a thing exist anywhere? I am looking to replace the soundbar that does not connect to the app with one that does - but being sure I buy the right one is the issue.
Thanks for any help anyone can offer.
Welcome!
This forum was set up a number of years ago so customers could help other customers with the SmartThings ™ home automation platform. It’s not officially monitored by Samsung employees except for the usual issues of spam and harassment, and a small section for developers.
You might get a quicker answer in the official Samsung support forum, which does have staff assigned to it who have access to Samsung databases that we don’t.
Of course you’re welcome here, and people will try to help, but that help may be limited. For a question like this you’re more likely to get pre-sales support at the other site. It’s worth a try, anyway. 
I’m pretty sure they cover sound bars in the “home theater” section.
Does anyone know if you can use Smarttag with the smarthings App on an Iphone?
You cannot, just as you cannot use an apple AirTag with an android phone.
