Hi folks, so I've got a QE55Q90RATXXU TV and when I jump into the Smart Things app on my phone, it says the TV is offline.  But the TV definitely isn't as we don't have an aerial so we stream everything on our wifi and both my phone (and the app) and the TV are running on the same wifi so why does Smart Things think my TV is offline.

Also struggling to connect a pair of BOSE wireless headphones to the TV if anyone can help with that.

TIA Anne
