Total Beginner - MM2 with MacMini

[Stoffbeuteluwe]

Hi, do you have pm2 installed on your Mac?
Is pm2 working?
Did you installed pm2 in MagicMirror directory?

[sdetweil]

@trividar there is a module that uses camera,

https://github.com/dmcinnes/MMM-Motion-Detection

I also have one, that allows configurable ways to sleep… pi, hdmi off, or blanking screen

https://github.com/sdetweil/MMM-SleepWake

mine depends on the github motion project for camera interface

https://motion-project.github.io/

I have not tried mine on mac. but motion project is supported on mac.

[Stoffbeuteluwe]

@trividaryou can do this with the harmony hub (Logitech) and a motion sensor…all that works with Alexa… Turn tv on or off with motion sensor…or voice

[Stoffbeuteluwe]

Must pm2 be installt in Magic Mirror directory?

[Stoffbeuteluwe]

install pm2 on Mac is my biggest problem 😭

[trividar]

@sdetweil Thank you for your reply and sorry for my late reply. I’m not able to get it to work with my Mac mini ;o) I have a USB Camera and a mac mini 2012. Would it be possible for you to write a step by step instruction? Many thanks in advance!!

[trividar]

@Stoffbeuteluwe good point! But I will use a camera behind the mirror to have a clean build.

[sdetweil]

@trividar the motion project installs a new program that runs in the background, and uses the camera.

it can record video, take pictures, and notify of those kinds of events. in general, it has nothing to do with MagicMirror.

but I had used it for another mirror runtime, and wanted the same capability here…

in the motion.conf, you set the notifier for motion start and stop to execute the script i provide in the MMM-SleepWake module.

on my odroid system that looks like this
(on pi it would be /home/pi/, on mac it would be /Users/??? where ??? is the user where MagicMirror is installed)

# Command to be executed when an event starts. (default: none)
# An event starts at first motion detected after a period of no motion defined by event_gap
on_event_start /home/odroid/MagicMirror/modules/MMM-SleepWake/external_motion start

# Command to be executed when an event ends after a period of no motion
# (default: none). The period of no motion is defined by option event_gap.
on_event_end /home/odroid/MagicMirror/modules/MMM-SleepWake/external_motion end

i just tested the motion detection script on mac and it needed work, thanks!
I have updated the repo on github…
just do a

git pull

from the MMM-SleepWake folder, to get the update

[trividar]

@sdetweil thanks! I will try it later this week!

@sdetweil So I have tried to get your module to work, but unfortunately without success. Could you please help me?
So what I have done:

1. Cloned motion-project into my folder Mirror (there are now two folder, MagicMirror and motion)

2. Created motion.conf and made those changes:

# Command to be executed when an event starts. (default: none)
# An event starts at first motion detected after a period of no motion defined by event_gap
; on_event_start ‎⁨/Users/..../Mirror/MagicMirror/modules/MMM-SleepWake/external_motion start

# Command to be executed when an event ends after a period of no motion
# (default: none). The period of no motion is defined by option event_gap.
; on_event_end /Users/..../Mirror/MagicMirror/modules/MMM-SleepWake/external_motion end

3. Configured my ~/MagicMirror/config/config.js file:

	{
    module: 'MMM-SleepWake',
    delay:  1,               // default (one minute just for testing)
    source: 'external'
    
},

4. Started my MM without error, but SleepWake don’t do anything my MM just shows everything without going to sleep!

So did I miss something? (My hardware: Mac Mini (late 2012) Monitor over HDMI connected.
Thank you!

@trividar I need to know how to turn off display,
So we need mode:

See the readme

I have only three modes at the moment, hide ( hide all modules, don’t turn off display), dpms (use the dpms commands), and pi( which uses the pi only tvservice command)

I would try mode: ‘hide’ first.

I don’t know how to turn off/andon the Mac display.

[sdetweil]

researching, i found supposedly

pmset displaysleepnow

should work

it does not on my mac virtual machine…

does it work on real mac?

man pmset 

should show the help for this

displaysleepnow - causes display to go to sleep immediately.

[sdetweil]

@sdetweil

using MMM-SleepWake with mode: ‘Hide’ works (any case is allowed)

executing the external script wakes up

/Users/.../MagicMirror/modules/MMM-SleepWake/external_motion start

that is like what u have configured.

you should see the camera motion events in /var/log/motion/motion.log
(motion has to be running of course)

[trividar]

@sdetweil So do I understand it right, I have to add mode in the config.js file like this:

	{
    module: 'MMM-SleepWake',
    delay:  1,               // default
    source: 'external',
    mode: ‘Hide’


},

and I have to start motion separately from MM is that right, if yes how?

[sdetweil]

@trividar yes, and yes.

I start the motion program as part of the little script to start mm.

Short term just type

sudo motion &
