How do you switch on / off, wake up yours?
-
I’m in the final stages of construction and happy with the basic installation of hardware and software. My Pi sits inside a frame with a monitor, and I can vnc in to it.
What I’m interested in, is everyone’s methods for switching on / off and waking up etc.Do you leave it switched on all the time? (not my preferred choice as noone is in the house during the day and that seems a little wasteful)
If not, how do you wake up your screen or Pi? PIR sensor, camera, some kind of switch, remote access?
-
I intend to use a PIR sensor “almost hidden” in the frame.
-
Thanks yawns, which module will you be using - MMM-PIR-Sensor?
Out of interest, do you know if it’s possible to set the time the hdmi stays live for, or is it purely based on whether there’s any movement detected?

I’m using a motion cam behind the mirror with mmal motion software running outside the mm2 as a surveillance cam!
If there is a motion in the front of the mirror the cam turns the mm2 panel on.
After some time without motion the sw will deactivate the panel.

I just use a cron job to put the screen to sleep at 11pm and turn it back on at 7am. My schedule is routine enough that this works well for me.
crontab -e
00 23 * * * /home/pi/monitor-off.sh >/dev/null # JOB_ID_1 0 7 * * * /home/pi/monitor-on.sh >/dev/null # JOB_ID_2#!/bin/bash vcgencmd display_power 0 # export DISPLAY=:0.0 # xset dpms force off#!/bin/bash vcgencmd display_power 1 # export DISPLAY=:0 # xset dpms force on # xset s reset

@lolobyte a question
is the cam on all the time? i´m interested to use the pi cam as a surveillance cam (something like an ip cam) und using a mm module for motion detection (wake up the screen etc.)
-
yea, all ways on.
If the cam recognize some motion in the front, the monitor is starting.After a chosen delay time the monitor is switched off.

@arbeyukay I combined the Magic mirror with this feature and have a USB cam to detect any motion in front of mirror, if no motion the monitor is shut down. Works just fine!

I personally use remote control to turn my display on. I also am thinking of using motion detection, but I probably need help. https://forum.magicmirror.builders/topic/52/pir-sensor-put-your-mirror-to-sleep-if-not-used/30
