Hi all,

I just come back on this topic because I followed the install process as described by hawking:

@Natacha3
Are you aware of https://forum.magicmirror.builders/topic/988/motion-detection-with-raspicam-non-module-version
The linked thread provides a precompiled version of Motion and some recommended settings.

So I just open a command window and do the following command ./motion -c motion.conf
then I open another window and I start the MagicMirror with npm start

Everything works fine for a couple of hours then the Mirror stays dark

I do a CTRL Q
and in the motion window I get the following :

[1] [NTC] [ALL] motion_loop: fps: 3.998576 idle 63.46% over 0.00%

[0] [ERR] [ALL] main: Thread 1 - Watchdog timeout, trying to do a graceful restart
[0] [ERR] [ALL] main: Thread 1 - Watchdog timeout, did NOT restart graceful,killing it!
[0] [INF] [ALL] motion_cleanup: Calling vid_close() from motion_cleanup
[0] [INF] [VID] vid_close: calling video source cleanup
[0] [ALR] [VID] MMAL Camera cleanup

So I can see that some detection occured properly and pictures have been saved in /run/shm/lastsnap.jpg
(I checked, this function is deactivated but … anyway ! Only 1 pic is stored so it’s not a matter of folder flooded)

The Watchdog timeout would be a possible lead but google does not help me so much as so many different issues are linked… :cry:

I hope that you will forgive me if I asked a stupid question and what you will be rather indulgent not to turn me down !

@natacha3 - It’s been a really long time since I wrote that Motion post. But I’ll try to help. IIRC, the lastsnap.jpg is intended to be a capture of the last image that the Motion system grabbed. It will continually overwrite that file. You may (or maybe not) have disabled the “capture screenshots to folder” functionality and left the “save last image to folder” feature running. Or not. I’d have to see your motion.conf file to be sure.

Motion never did close gracefully, to my knowledge. It seems that motion is definitely detecting motion of some form and writing to the lastsnap.jpg file. So that’s a plus. If you read the whole thread that @Hawking linked, you’ll see that I had problems with Motion crashing. When it crashes, it stops detecting properly and never runs the script to wake up the monitor.

I suspect that if you check the lastsnap.jpg timestamp, you’ll see that it was created at some point between “works fine” and “won’t turn the monitor on”. That would be the last time that motion successfully wrote to the disk before the process crashed.

Try starting Motion with pm2. I found that pm2 will detect when the Motion process crashes and restart it for you. That should keep the detection active.

@bhepler, you’re my hero !

Thank you so much for your kind advice !
Starting motion with pm2 solves the issue.
I just did not dare to start also the magic mirror with it as I’ve read somewhere that they would start simultaneously and as a consequence everything would fail… I will try but later on !

Thank you agin !
