I just bought an Amazon Echo 2nd gen with bluetooth capability. The Echo has a good speaker, but my UE Megaboom is better. Not only that, but I want to put the Echo in my bedroom and the Megaboom in my living room so that all I have to do is turn on my Megaboom when I want music in both rooms. However, it seems that the Echo will only let me play music on either the Echo or the Megaboom, not both. Has anyone figured out how to connect a bluetooth speaker to the echo and have sound come from both devices?
