thx, just found it. But ~9m² away from order :-(. And

We are not 9m² away from being able to order, it will just get cheaper with more than 20m². (There was an update to the conditions)
From what I understand, ordering is possible with the current amount already.

Ok, i posted in the thread, lets see the progress.

Another thing is, my monitor has a touchpad connected with flat wire to the frame alt text
I am just wondering how the raspi could even switch the monitor on or how i will control the Magic Mirror ;)

@fox maybe you can hack the soft buttons, and emulate them with the pi over gpio pins, write some code …

Good idea this could work. Even when the brightness / contrast is adjusted i need only P_ON/OFF, and i can put a signal on the GPIO Pin when the raspi boots, soldered parallel on the wire.
Thx for this idea!

Remember, the pi GPIOs can only handle 3V3. Check the voltage of the monitor buttons with a multimeter before soldering. You will likely need a level shifter.

I have disassembled the monitor and have seen that I can’t give the signals per gpio.

It’s a serial connection and I can’t simulate the protocol.
So, is it possible to use the LCD Screen?
It’s a m240hw01 v2

@fox It’s possible. If you configure your Pi to turn off the signal to the HDMI port, the monitor should shut off automatically. It should remain off until it detects a signal again, whereupon it will turn itself back on.

The MotionDetection module can do this for you with a Raspberry Pi camera. Otherwise, there is a module for using a PIR sensor.
