for everybody who likes to save energy
I now have a full automatic power off after shutdown. Power supply included!
I bought an Ansmann AES3 energy saving unit for only 11,98€.
Here with the mamboberry LS DAC+ and Volumio installed and a ifi iPower supply.
The trick was to calibrate the standby off with nothing in the AES3, because the RpI consumption is so less.
You may have to change the calibrating procedure with your own setup, that the AES3 recognise the switch off point.
On my measuring device the Raspberry with DAC and power supply will take about 1,5watt when off, at playing about 4 watt - with this solution 0 watt.
Also, i dont’t have to stand up from bed to switch off completly the musicbox.
