The washer / dryer doesn’t need a hub as it connects directly to your online account via WiFi and I believe the TV is the same. So you can still use the SmartThings app to control it. I just installed the Samsung SmartThings app on my phone from the Android store and I can view and control my washer / dryer in there. Actually, I think I had to setup the washer via the app, but it was a long time ago so I could be wrong.
The hub is only needed for ZigBee and Zwave devices but obviously yu already have Homey for that.
