MMM-SleepWake using external motion detection source

sdetweil

Description

Enable MagicMirror sleep from external (camera) sources

If you are running the MM on a non PI device, or want to control sleep/wake without having to wire up another device, this module will take external info and signal MM to sleep or wake up.

I use a Webcam camera for the motion detection, driven by the github Motion project.
That project allows for a script to be run when motion starts and ends. I provide a script that
creates a file for both events, and the module detects those files.

the module supports sleep and wake 3 different ways… On PI using the tvservice command, or the exec dpms command if not using HDMI, or hiding all modules if using an energystar monitor (like my tv)

I have submitted changes to MMM-voice and HelloLucy to allow our modules to know about the others processing… so voice Go To Sleep and motion wakeup work… if using the Hide method, modules already hidden at sleep will remain hidden on wakeup.

@sdetweil

Well done, sir!

elleclouds

Can this use a Nest Smoke Detector’s motion detecting as a trigger to activate SleepWake?

sdetweil

@elleclouds I do not know. Is there a nest API the reports motion?

I have not found the same for my ecobee room sensors

If u can find the API, just call my little shell script to report start and end of movement

elleclouds

@sdetweil Can this script be used with a raspberry pi camera? I want my mirror to wake and sleep upon detection from camera. It there a step by step for a noob as myself?

sdetweil

@elleclouds I didn’t want to learn all about cameras, or be on the hook for continuing configuration options for cameras… and I found this code that handles all that AND signals motion

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

on its configuration page its says

Determine the type of camera
v4l2 devices which are most webcams
Composite capture cards
Network or IP cameras
The PI camera
Static movie files.

it documents using the Raspberry Pi camera

Raspberry Pi cameras can be set up two different ways. If Motion is installed by using the apt packages (e.g. apt-get install motion), then the camera must be set up using the bcm2835-v4l2 module which creates a v4l2 device for the camera. Users will need to install this module using the command sudo modprobe bcm2835-v4l2. This will set up the camera as a normal v4l2 device and it can be accessed via a standard /dev/videoX device. If Motion is built from source or installed via the deb packages on the project release page, then an additional option is to set up the camera using the mmalcam_name parameter or using the bcm2835-v4l2 module. When Motion is installed via apt, the mmalcam option is not available.

Motion project can also record images on motion, movies, etc,etc,etc,etc,

I am a noobie, but I feel like I followed most of the instructions I’ve found online on how to get this to work, but I’m still having some issues of actually getting the mirror to turn of or on. I keep getting the error in terminal when I run motion : vid_v4lx_start: Failed to open video device /dev/video: No such file directory.

I’d greatly appreciate a video or help with set up… A youtube video would save me time and troubleshooting something that may be simple.

sdetweil

@elleclouds ok…
the motion module needs a video device…

run these two commands

sudo apt-get install v4l-utils
v4l2-ctl --list-devices

find the ‘camera’ device in the list
mine shows

odroid@odroid:~/MagicMirror$ v4l2-ctl --list-devices
s5p-mfc-dec (platform:11000000.codec):
        /dev/video10
        /dev/video11

s5p-jpeg encoder (platform:11f50000.jpeg):
        /dev/video30
        /dev/video31

s5p-jpeg encoder (platform:11f60000.jpeg):
        /dev/video32
        /dev/video33

exynos-gsc gscaler (platform:13e00000.video-scaler):
        /dev/video20

exynos-gsc gscaler (platform:13e10000.video-scaler):
        /dev/video21

UVC Camera (046d:0825) (usb-xhci-hcd.3.auto-1.2):
        /dev/video0

the last is the camera…

so, in the motion.conf,

set the line videodevice to the value returned for the camera, in my case /dev/video0

# Videodevice to be used for capturing  (default /dev/video0)


# for FreeBSD default is /dev/bktr0
videodevice  /dev/video0

after changing the config file
either do

ps -ef | grep motion
     get the process id (pid) use below
kill -s SIGHUP pid

mine is

odroid@odroid:~/MagicMirror$ ps -ef | grep motion
root      7756     1  0 Mar08 ?        00:14:21 motion

pid = 7756

or reboot
