Hello,

Can I use some sort of Bluetooth or WiFi amp device to connect to my old but excellent stereo speakers? I want to slowly build out my smart house. Good music in many rooms would be nice. As a retired person I don't have the money to buy a bunch of Echo devices. Also who knows which home system will "win"? Amazon, Google, Microsoft, & etc. It would be nice to have an open source solution.

Please help.

I didn't find the right solution from the Internet.
