Hi there
running a Beocreate with a Raspi4. Absolutely fabulous !
Sure, i can shutdown the Raspi by software, but it would be nice to have a hardware switch to gracefully shutdown the Raspi and Beocreate.
Standby consumtion is quite high, so in combination with a switch or button a relay ( eG Shelly Switch ) coud cut the main power supply as well.
any ideas ?
thx in advance

I think, the best way is a power switch (as a Shelly) on mains level. The Beocreate itself does not have a power-switch feature. Therefore, if you really want to have reduce power consumption, a mains switch is the best way.
yes; thats for sure, but how to gracefully shutdown the Raspi ?
just depowering the Raspi crashes the SD Card rapidly.
How to send the Raspi the shutdown command ?
Depends on the software you're using. With HiFiBerryOS I wouldn't care to much. Writes to the SD card are greatly reduced, just powering off the system is very low risk. I do it here every day.
You can still shut it down via the UI if you like.
If you buy some extra hardware (IR Remote + Remote Pi Board, relay, 5v powerregulator), you can do this from menu or remote. Only problem is that it will not work with HifiberryOS but only with third party software like Volumio or MoodeAudio. You also need to change confix.txt and have to install LIRC and add some extra scripts.

Perhaps an idea to add LIRC to HifiberryOS?

All the existing Pi power boards have one major problem: They only work with the 5V on the Pi. That's not really good with the Beocreate (or other amplifiers) as the board itself it still powered. However, it you can wait a bit longer, we're just working on something cool (won't say more before it's ready).
