6 Dots, 1 Bluetooth whole house sound system. Commands from each Dot to 1 BT

[bobmurrayiii]

Hello,

I have just purchased 6 dots for my new house. I would like to be able to speak to any dot (i.e. "Alexa, play the Rolling Stones" and have the output go to a single BT input in the closet outputting to the whole house sound system. I can see how one Dot can do that to a single nearby BT device, but is there any way to have the other Dots feed to the same BT device?

I also have the Alexa voice remote and a 4 or 5 Logitech remotes with IR blasters. Also, the in-wall room keypads for the 6 zone sound system have IR inputs. So with Logitech blasters I can turn on/up the sound in each room, but how about getting the music from the local dot to the BT in the closet?

I know I may be duplicating a thread, if so send me to the right place. Thanks!

PS I also have a Lowe's Iris hub in the house, if that helps.

Bob
