I want to be able to keep Sono's roam powered on all the time while it's connected to a charger and while not connected via Bluetooth to any device because I am using this speaker as the main speaker for my MacBook laptop.

When my laptop is connected via Bluetooth, it doesn’t get turned off automatically which is good.

Whenever I had to go outside and come back Sonos automatically got powered off and I had to manually press the button to Powered on which is a bit annoying. 

I have already tried by disabling battery saving mode as well. Didn’t work.

Additional Request: Can we have a way to powered the speaker from a cable rather than a battery while connected to a charger?
