becouse im not expert in all this raspberry pi things i just found out that GPIO14 (pin8) is set to "output - high" just 2-3 sec after power is applied to rpi, and it stays in that state until shutdown command is executed, that means that "relay.py" is not needed anymore. all you need to do is to connect 5V delay relays signal to GPIO14 (actual pin8).
thats it
thats it
