Message-ID: <[email protected]>
Content-Type: text/plain; charset="UTF-8"
Hi
just 8 cams on my system, one really needs to be disabled during the
day,
At the moment I'm sending a script in homeassistant
lounge_cam:
command_on: 'lwp-request
http://localhost:7770/101/detection/start'
command_off: 'lwp-request
http://localhost:7770/101/detection/pause'
sorry for the line wrapping, it doesn't always work as verification is
a pig to get to work, So far I have failed ,
I have logging set to 8 and I have tried to use grep to find the
response to the lwp-request.
If it was only just using it for a few hours at night, I could use
crontab , but it also needs to be on if we are out or away from home.
with 8 cameras and on log level 8 there is a lot being added to the
logfile.
Am I missing a simple way of doing this ???

?Best wishes ?

What I've seen is that people use a bash script that pings their phone.?
If the ping returns then disable the camera(s), if not, then turn the
camera(s) on.? Then use a crontab to run the script at some sort of
frequent interval.

Hi,?
I'm dong something similar to that, by tracking both my phone and my
wifes, and if both are out or we have set a state switch we are away,
the the lwp-request http....../pause is sent
and if either of us are in the
lwp-request http......../start is sent
and also at a time in the evening the lwp-request ..../start is sent
and the opposite in the morning
the problem is its a blind command and doesn't always get actioned by
motion, or gets lost
from the logfile there is

I've tried running tail -f motion.log | grep Decoded url > a file
but haven't succeeded in setting a flag that can be read by another
application/program like homeassistant
this sorta works
tail -f /var/log/motion/motion.log | grep Decoded
[0:cn0] [DBG] [STR] [Oct 23 17:28:40] webu_parseurl: Decoded url:
/101/detection/pause
[0:cn0] [DBG] [STR] [Oct 23 17:28:41] webu_parseurl: Decoded url:
/101/detection/pause
But I haven't succeeded in writing the output of grep to a file

When I've had these type of messages it's been due to either hardware
problems or overloading the (usually) rpi - i.e. Two USB webcams on one
rpi. Funnily enough I've just had it recently and it was a faulty camera
module. It took me a while to diagnose because the camera and cable
looked fine, and I swapped them both, and they still failed. Only when I
swapped them with the module on a working rpi that I noticed.
As for automatically restarting motion if it crashes, I found some old
code that I used to run every few minutes from cron, that allowed me to
kill and restart motion remotely using a dropbox file. (I used to start
motion when it wasn't running, now I rely on system startup and a daily
restart via cron. It seems to work better for me.)
I used to use something along the lines of:
wf1=/home/dougie/tmp/$(basename -- $0)_1.$$
if ps -C motion > $wf1 2>&1
then
?? ?ps -C motion > /tmp/.motion.is.running
else
?? ?cat $wf1 | mail -s "INFO: Starting motion - $(basename --
$0)[$LINENO] [PID $$] - " -r "<sys-$(hostname)@katsura.uk>"
[email protected]
?? ?nohup motion > /home/dougie/logs/motion.log 2>&1 &
fi
Depending on your version of Linux/bash perhaps something like 'pgrep'
in a script might work better than the way I've done it, using ps -C. If
I'm trying to do something like this nowadays I'd look at using
something like pkill and pgrep to check and restart motion. I always run
motion as myself and not as user 'motion' btw.
(I saw another question about disabling motion using a time parameter -
this doesn't do that but I find the 'rclone' command with dropbox pretty
useful. If you use dropbox of course :-) Here's the code I use.)
wf1=/home/dougie/tmp/$(basename -- $0)_1.$$
#
#??? Check Dropbox to see if motion should be stopped
#
if rclone cat remote:etc/stop-motion-running.txt | grep -q ^yes
then
?? ?if ps -C motion > /dev/null 2>&1
?? ?then
?? ???? cat $wf1 | mail -s "INFO: Stopping motion - $(basename --
$0)[$LINENO] [PID $$] - " -r "<sys-$(hostname)@katsura.uk>"
[email protected]
?? ???? rm /tmp/.motion.is.running >> $wf1 2>&1
?? ???? pkill -u dougie motion
?? ???? sleep 10
?? ???? pkill -9 -u dougie motion
?? ?fi
