Do you need to use the app to control devices in cabinets
It looks like you can use blue tooth from your smart phone/ipad etc to control hidden devices but can the remote control also control dvd players and other devices behind closed doors?
Yes. If you use the wireless hub all of your devices are controlled from either your smart phone or with the wi-fi remote that is included. I have a Bose system,PS3, Directv box, on one wall in a cabinet....and a flat panel mounted over the fireplace on another wall. All pieces work with the hub in the cabinet. I did not need to use the ir blaster that it came with.
