PiKrellCam

[MarnixO]

Anyone uses a script in PikrellCam to make an action in Domoticz on starting motion capture
Or sending email with pictures ?

[Egregius]

I do.
Will try to post something this evening.

[Egregius]

I have this in pikrellcam.

In .pikrellcam/pikrellcam.conf:

Code: Select all

on_motion_begin /home/pi/region.py
on_motion_end /home/pi/on_motion_end.sh

/home/pi/region.py:

Code: Select all

#!/usr/bin/env python
import os,sys,socket,time
from subprocess import Popen
from shutil import copyfile
hold = 5000
holdoff = 180000
filename = '/run/pikrellcam/motion-events'
file = open('/run/pikrellcam/motion-events','r')
state = 'wait'
tsent0 = open('/temp/tsent0').read()
tsent1 = open('/temp/tsent1').read()
tsent2 = open('/temp/tsent2').read()

while 1:
	where = file.tell()
	line = file.readline()
	if not line:
		time.sleep(0.01)
		file.seek(where)
		continue
	line = line.strip('\n')
	if (line.find('<motion') == 0):
		state = 'motion'
	elif (line.find('</motion>') == 0):
		state = 'wait'
	elif (line.find('<end>') == 0):
		sys.exit(1)
	elif (state == 'motion'):
		if (line.startswith(str(2))):
			tnow = int(round(time.time() * 1000))
			if (tnow >= int(tsent2) + holdoff and tnow > int(tsent1) + hold and tnow > int(tsent0) + hold):
				r, x, y, dx, dy, mag, count = line.split()
				if (int(mag) >= 2 and int(mag) <= 40 and int(count) >= 110 and int(count) <= 3000):
					copyfile('/run/pikrellcam/mjpeg.jpg', ('/temp/snapshot-%s-%s.jpg' % (r,tnow)))
					tsent2 = tnow
					with open('/temp/tsent2', 'w') as myFile:
						myFile.write('{}'.format(tsent2))
					Popen('/usr/bin/php /home/pi/pikrellcam/www/telegram.php %s %s %s %s' % (('/temp/snapshot-%s-%s.jpg' % (r,tnow)),str(r),str(mag),str(count),),shell=True)
		elif (line.startswith(str(3))):
			tnow = int(round(time.time() * 1000))
			if (tnow >= int(tsent0) + holdoff and tnow > int(tsent1) + hold and tnow > int(tsent2) + hold):
				r, x, y, dx, dy, mag, count = line.split()
				if (int(mag) >= 2 and int(mag) <= 40 and int(count) >= 130 and int(count) <= 3000):
					copyfile('/run/pikrellcam/mjpeg.jpg', ('/temp/snapshot-%s-%s.jpg' % (r,tnow)))
					tsent0 = tnow
					with open('/temp/tsent2', 'w') as myFile:
						myFile.write('{}'.format(tsent2))
					Popen('/usr/bin/php /home/pi/pikrellcam/www/telegram.php %s %s %s %s' % (('/temp/snapshot-%s-%s.jpg' % (r,tnow)),str(r),str(mag),str(count),),shell=True)

I have multiple motion zones set. I only want zone 2 and 3 to sent me a telegram with the picture.
The rest is handled in a php script, but this should get you starting.
Let me know if you need anything else. Been using pikrellcam for several years now, I'm pretty happy with it.

[MarnixO]

I only want to switch a virtual switch by movement in 1 zone
Sending a snapshot can be done by sending a notification
Many thanks for the fast response

[Egregius]

What do you want to achive by setting a switch on movement?
In my case that’s handled by the php script wich first checks several switches like home/away, gate open etc.

[MarnixO]

can i have a copy of that script ?

[Egregius]

I'll try, but it seems to be a mess

So the python script launches this script if movement is detected:

On my domoticz server I have camera.php wich gives the status of some devices. For instance I don't want to receive images if my garage port is open. And when I'm a sleep the notification must be delivered silent.

That script in turn triggers the beep.php script wich plays a sound on a Xiaomi gateway.

I think my programming knowledge is a bit inadequate for this

[Egregius]

What do you want to achive with it?

[Egregius]

Out of my head, in other words: not tested...
Maybe this will do for your case:

Set a switch to on when there's motion, set it to off when motion stops.
Keep in mind that this will trigger the on status on every new movement detected. If you don't want that you'll have to look at my tsent0 stuff in my first python script in this topic.

Code: Select all

#!/usr/bin/env python
import os,sys,socket,time,urllib2

filename = '/run/pikrellcam/motion-events'
file = open('/run/pikrellcam/motion-events','r')
state = 'wait'

while 1:
	where = file.tell()
	line = file.readline()
	if not line:
		time.sleep(0.01)
		file.seek(where)
		continue
	line = line.strip('\n')
	if (line.find('<motion') == 0):
		state = 'motion'
	elif (line.find('</motion>') == 0):
		state = 'wait'
	elif (line.find('<end>') == 0):
		urllib2.urlopen("http://192.168.2.2:8080/json.htm?type=command&param=switchlight&idx=1383&switchcmd=Off")
		sys.exit(1)
	elif (state == 'motion'):
		urllib2.urlopen("http://192.168.2.2:8080/json.htm?type=command&param=switchlight&idx=1383&switchcmd=On")

Wonderful, I will only be able to try this weekend because the pikrellcam is in a remote location

[MarnixO]

I noticed that there was no subdirectory scripts in the pikrell directory and I created them
then I placed the script with the extension .py in this directory and made it executable
I also noticed that there is an asterisk in front of script.py, does this have any influence on the script ?
In the log window I do not see any message or reference to the script

[Egregius]

Where is that asterisk?
And has never been a mention about a scripts folder. The config on_motion_begin holds a absolute path to avoid issues with that.

[MarnixO]

The asterix appears in the directory list in Midnight Comander
If I understand correctly I have to uncomment the on_motion_begin section
and put the script afterwards in the pikrellcam.conf

[Egregius]

Don’t know what that asterisk means, never heard of mc before. Will check that tomorrow.

Yes, add the complete path to the python script in pikrellcam.conf as mentioned in one of my first replies.

[MarnixO]

Thank you very much for your help
Once you know it, it's easy, but you have to know where to start
I am starting to get more and more interested in the script language, thanks to you
