Hello there,

My old TV broke. It is Not really good for watching TV anymore but it would still work as a SmartMirror.
So I wanna build one out of it, this will be my second. My first is a old Tablet.

I wanna hang in on a Wall with a wooden frame and a Raspery behind it which is doing all the work. Maybe also Touchscreen and voicecommands.

But I have one question because of the Energieusage.
I want the TV something like “off” when nobody is walking in front of it or turning it on.
But when you really turn off a Tv and want to start again it is booting this todays for a while, something like 30 seconds.

I want this mirror always be ready to show something within one or two seconds when I press a button or walk in front of it. Without booting the TV every time. I also want the screen to go off after 30 seconds with no movement detection or when I press a button.
So the raspery needs to be running al the time in the background yes but how do I do that with the tv?
Is there something like a mode between off and on like a black screen or a energy saver which can be turned on and off controlled by the raspery?

I really don’t want the tv always on showing black Color and burning tons of energy.

Thank you,

Best wishes,

Anthem
