MMM-SleepWake using external motion detection source

[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

this is exactly what I need. works perfect! just hiding modules and no more ugly “NO SIGNAL” message floating on my mirror. Thank you!

[sdetweil]

@mithatcak glad its working !.. i use it everyday on multiple mirrors…

@sdetweil I noticed a weird issue. sometimes after several sleep&wake cycles, when it goes to sleep only the stock currentweather and weatherforecast modules stays on. there is no error in the motion.log or MM log.

here is my config, I was using delay: 5 then switched to 0.2 so I can repeat the issue faster.

{
			module: "MMM-SleepWake",
			config:{
				delay:  0.2,               // default
				source: "external",
				mode:  "HIDE"
			}
			 // detectionDir: folder containing externally generated file when motion starts
			 //               will be created if needed
			 // detectionFile:  filename generated for motion start. default = 'detected'
},

@mithatcak very interesting… I use those default modules too and I have never seen that behavior.
like they didn’t handle the suspend request…

i have 4 systems running this everyday for months… only see the updatenotification module output on one as it doesn’t handle hide/suspend…

i will do some additional debugging

[sdetweil]

@mithatcak could you try something for me

i cannot reproduce this on any of my systems…

edit the MMM-SleepWake.js file

		case "SLEEP_HIDE":
			MM.getModules().enumerate((module) => {
				// if the module is already hidden
				if(module.hidden==true)
					// save it for wake up
					{v_self1.previously_hidden.push(module.identifier);}
				else
					// hide this module
					{module.hide(1000);}   // < --- change this line , remove the 1000 
```
should look like this
```
		case "SLEEP_HIDE":
			MM.getModules().enumerate((module) => {
				// if the module is already hidden
				if(module.hidden==true)
					// save it for wake up
					{v_self1.previously_hidden.push(module.identifier);}
				else
					// hide this module
					{module.hide();}
```

let me know

[mithatcak]

@sdetweil Unfortunately same result :/ I will try to replace currentweather and weatherforecast with weather module and see if it’s going to make any difference.

[mithatcak]

@sdetweil Good news, switching to new weather module fixed the issue.

[sdetweil]

@mithatcak interesting
