Running script from a Domoticz switch

[Teknor]

I have Pikrellcam installed on my Raspberry Pi 3 for motion detection purposes. I have created two scripts pikrellOn.sh and pikrellOff.sh in the folder pi/domoticz/scripts

The pikrellOn.sh looks like this

Spoiler: show

echo "motion_enable on" > ~/pikrellcam/www/FIFO

and

echo "motion_enable off" > ~/pikrellcam/www/FIFO

When running ./pikrellOn.sh or pikrellOff.sh I can turn on or off motion detection. So far so good. However, I would like to do this with a Domoticz switch. I have created a dummy switch and tried different variations of triggers, but not succeeded. Can anyone point me in the correct direction? ...might need a detailed description here.

Did you set the EXECUTE bit for the pikrellOn.sh? (sudo chmod +x pikrellOn.sh)
Try using the full path: script:///home/pi/domoticz/scripts/pikrellOn.sh

Hi - yes did run sudo chmod +x for both files. I guess that's why I can run them with the command ./pikrellOn/Off.sh

[jvdz]

ok.. and did you try the second suggestion? guess it also needs home in the full path?

Thanks @jvdz for following up on this one.

Yes, no luck with that either.

These work fine:
~/domoticz/scripts $ ./pikrellOn.sh
~/domoticz/scripts $ ./pikrellOff.sh

..these do not work:
On action: script:///pi/domoticz/scripts/pikrellOn.sh
Off action: script:///pi/domoticz/scripts/pikrellOff.sh

edit: including ///home/pi.... give error in the Domoticz log

..these do not work:
On action: script:///pi/domoticz/scripts/pikrellOn.sh
Off action: script:///pi/domoticz/scripts/pikrellOff.sh

Are you sure that those paths are correct? Maybe those should be something like script:///home/pi/domoticz/scripts/pikrellOn.sh

Your bash script needs to start with a 'shebang' line at the very top:

Code: Select all

 #!/bin/sh

or

Code: Select all

 #!/bin/bash

Changed the path to:
script:///home/pi/domoticz/scripts/pikrellOn.sh
script:///home/pi/domoticz/scripts/pikrellOff.sh

From the Domo log:

Changed the scripts to

Code: Select all

#!/bin/sh
echo "motion_enable on" > ~/pikrellcam/www/FIFO

...still no luck...

These work directly from the terminal, now the scripts also include "shebangs"

Code: Select all

pi@raspaux:~/domoticz/scripts $ ./pikrellOn.sh
pi@raspaux:~/domoticz/scripts $ ./pikrellOff.sh

Solved!

Thanks all. Solution was to specify the whole path in the script

Before

Code: Select all

#!/bin/sh
echo "motion_enable on" >  ~/pikrellcam/www/FIFO

Now

Code: Select all

#!/bin/sh
echo "motion_enable on" > /home/pi/pikrellcam/www/FIFO
