I finally got this connected to Smarthings. I did try the other suggestions like power cord out for a few mins and router off for a while but still wouldn't accept to smartthings. The solution for me anyway is my wifi strength. I was using a 5ghz wifi which is fast but not as strong. My wifi router also as a 2ghz which obviously is slower but more powerful and more range. When I chnagfed down to the more powerful signal it connected first go. Hope it helps someone but I still don't get it. And I am still not impressed that so many people are having the same issues. Mind you when you do finally connect to Smartthings I don't think it was all that helpful unless I am missing something. Great soundbar but it DEFINIETLY needs some auto calibration method.... Cross fingers for all out there.
