@pddh I forgot to mention- i have a double switch installed. One for the bathroom lights and the other for the mirror light. So i can use the mirror light easily for the MM.
Later on i will break thru the wall and make a socket behind the mirror. So i have constant 220v and the Alexa behind the mirror will have always power.
I power off the rpi and monitor fully over night for saving some energy and daily fresh reboot.
