Is it possible to cut off the total power consumption of the RaspberryPi after shutdown

[Caliandroid]

My son forgets to switch off the phoniebox after the shutdown and even shut off, the speakers and rfid connected to the raspberry get/drain power.

Is there a simple way for a switchless total cut off?

There is a shutdown on idle option discussed here https://github.com/MiczFlor/RPi-Jukebox-RFID/issues/53 Do you think this can help on your issue?

@MiczFlor Is it still missing in the docs?

The existing shutdown on idle works but even after the shutdown, RFID and speaker (directly connected to the pi's onboard USB) still receive power .

I think you might need to fire up your soldering iron https://www.raspberrypi.org/forums/viewtopic.php?t=34603 And here is a thread regarding the power consumption of the relais https://www.raspberrypi.org/forums/viewtopic.php?t=133148

It is not possible to cut the power automatically without some extra hardware. If this works, depends on your setup. If you don't use a powerbank, the easiest way is to use a OnOff SHIM: https://shop.pimoroni.de/products/onoff-shim With a powerbank the OnOff SHIM is not working out of the box as there is no "power on" possible anymore (usually powerbanks switch off if the current drops below some value). I still have to do experiments to solve that problem, but i don't know if the solution will be "simple".

Thank you for the input. So it's not possible without extra hardware but it does not seem to be too complicated to build.

I am thinking about using ATXRaspi to manage the power off: https://lowpowerlab.com/guide/atxraspi/#installation
