Samsung M5 Speaker for announcing

Hey all,
I am trying to find a decent speaker for announcements from Smart Things. I am sure I read on here somewhere that the Samsung range of M devices work but I am unable to find the post I read and I am unable to get my M5 to play nicely with Smart Things.
I can see the speaker in Smart Things but I am unable to do anything with it. I have Big Talker and Media renderer running and both work with Lannouncer and VLC Thing. I was hoping the M5 speaker would be another option for them to talk to.

Anyone point me in the right direction or to a correct thread as I can’t seem to find one.
Many thanks
