Samsung R1 box says "works with smartthings" but it dont

I tried already that with a different speaker that supports dlna and same, speaker paired with its app and connected to the same WiFi but it won’t pair. I am just thinking if it has something to do my my router supporting UPnP stack…

Has anyone gotten the r1/wam1500 to connect to St

Yes. I have 2 working without issues for a couple of years now.

They do take quite some time to search/connect.

No go with my R1. Installed the multi speaker app. Have it configured and playing music thru the app just fine. However, SmartThings cannot find the speaker… Sad. Running a Google WiFi network and upnp is enabled.
