From the Bluesound tech support -
“
The NODE and other Bluesound Players are designed to be always on and always ready. They will go into Stand By on their own when idle for >15 minutes consuming less than 3W as required by EU Green initiatives.
Placing the player in VACATION MODE of pressing and holding it for 5 seconds powers down the player into a 0.5W stand by if you will be away for extended periods but is not designed as an ON/OFF switch. It will reboot from the start when you do this and can take up to 5 minutes to connect to network devices. You are also prematurely ageing the power supply when doing this. You cannot do this using a remote because the IR sensors are also powered down in this state.
Just set it and forget it. “
