Pi 3B+ HDMI turning off
-
@dazza120 magicmirror does not fiddle with the hdmi or monitor on its own. this is provided by some module.
the OS may have a power save mode that turns off hdmi…
-
@sdetweil it’s mmm-voice when I tell it to hide the module the feed goes eventually, I just left it on and turned off the monitor and everything is good so we are all good :) thanks
-
@dazza120 yes MMM-voice has code to turn off the display when it is told ‘go to sleep’
-
why dont you use a simple contactor ?

I use this
the script is very simple and it turn off or on my screen when I want
and I never get " no signal" … -
@seramik thanks but as said I already have a method of turning to TV off I just wanted the hdmi to stay live, as said it’s the mmm-voice that was the issue/cause
