I have a Yamaha dual zone receiver that has built in Bluetooth that allows me to control it through the Yamaha app on the iPhone. I have a 5.1 Polk ceiling speaker set in my living room. I have 2 additional ceiling speakers outside on my lanai and 2 upstairs in my master bathroom. The 2 sets of additional speakers are plugged into a selector box. So the 5.1 in the living room I can watch Cable and the two sets of lanai and bathroom speakers I can listen to music (the lanai and bathroom are on the same channel with volume control knobs). I now want to add some wireless Bluetooth speakers to my pergola out in the backyard since it isn't connected to the house. Can I do this?
