This is the final script ;-)

Hope some one can help me...
Do have a script to reboot the Pi.

Code: Select all

#!/bin/bash
    DomoticzState=`sudo service domoticz.sh status`

    if [[ $DomoticzState == "domoticz is running." ]]
            then
                    echo 'Domoticz is running. Nothing to do.'
    elif [[ $DomoticzState == "domoticz is not running ... failed!" ]]
            then
                    echo 'Domoticz is not running. Restarting Domoticz...'
                    sudo service domoticz.sh restart
                    echo 'Domoticz restarted.'
fi
With a Cron:

Code: Select all

*/2 * * * * sudo /home/pi/scripts/restart_domoticz.sh
Only a strange thing...
With the cli the pi is thinking it is running.

Only my webgui says offline...
Is there a solution for.???

It's not the same. Your script checks the status of the service, notthe actual response of the json api.

Ok only the strange part...
Do this [ the same] check by my Odriod Xu4.... and this is working great.
Only not by my { slave ] Pi.

What is then the best simple script [ without any message etc ] to use

This is the stripped version without notification and no log copy.
Change ip:port, rid= idx of a switch.

Code: Select all

#!/bin/bash
DOMOTICZ=`curl -s --connect-timeout 2 --max-time 5 "http://127.0.0.1:8084/json.htm?type=devices&rid=1"`
STATUS=`echo $DOMOTICZ | jq -r '.status'`
if [ "$STATUS" == "OK" ] ; then
   exit
else
   sleep 5
   DOMOTICZ=`curl -s --connect-timeout 2 --max-time 5 "http://127.0.0.1:8084/json.htm?type=devices&rid=1"`
   STATUS2=`echo $DOMOTICZ | jq -r '.status'`
   if [ "$STATUS2" == "OK" ] ; then
      exit
   else
      sleep 5
      DOMOTICZ=`curl -s --connect-timeout 2 --max-time 5 "http://127.0.0.1:8084/json.htm?type=devices&rid=1"`
      STATUS3=`echo $DOMOTICZ | jq -r '.status'`
      if [ "$STATUS3" == "OK" ] ; then
         exit
      else
         sudo /var/packages/domoticz/scripts/start-stop-status stop
         sleep 8
         sudo kill $(sudo netstat -anp | awk '/ LISTEN / {if($4 ~ ":8084$") { gsub("/.*","",$7); print $7; exit } }')
         sleep 8
         sudo /var/packages/domoticz/scripts/start-stop-status start
      fi
   fi
fi
This is for restart on a Synology (change port number):

Code: Select all

sudo /var/packages/domoticz/scripts/start-stop-status stop
sleep 8
sudo kill $(sudo netstat -anp | awk '/ LISTEN / {if($4 ~ ":8084$") { gsub("/.*","",$7); print $7; exit } }')
sleep 8
sudo /var/packages/domoticz/scripts/start-stop-status start
And for restart on a Pi (change port number):

Code: Select all

sudo service domoticz.sh stop
sleep 8
sudo kill $(sudo netstat -anp | awk '/ LISTEN / {if($4 ~ ":8084$") { gsub("/.*","",$7); print $7; exit } }')
sleep 8
sudo service domoticz.sh start

Dear E...

Thanks for the great support..
Only i am a dombo...

This part for :
sudo /var/packages/domoticz/scripts/start-stop-status stop\
Is only fr nas or something like that i think...

The pi version i will try..
I think i have to replace the part after : else

Only what idx can i take for the best?
The cpu ?
Or?

Any idx should do, as long as it is a used one. You can easily test by pasting the url in a browser.
Either you use the syno oines, or you replace those by the pi lines.

On my Synology I had to add my username and password into the curl command to get it to work, otherwise just got an unauthorized return.

You could also add 127.0.0.1 to the range that doesn't need to authenticate.

Hello Egregius

(rpi v2, domoticz v3.8015)
I am not a programmer, I just read and try to apply what I understand.
I'm trying to use the script, but this script restarts domoticz at the crontab time.
*/2 * * * * /home/pi/scripts/restart_domo.sh

During restart, they lose sensor actions.
I'm wrong somewhere???

My Dummy device (idx 6)
Status is OK but restarts domoticz at 2 minutes

http://192.168.2.173:8080/json.htm?type=devices&rid=6

}
],
"status" : "OK",
"title" : "Devices"
}
---------------------------------------------------------

#!/bin/bash
DOMOTICZ=`curl -s --connect-timeout 2 --max-time 5 "http://192.168.2.173:8080/json.htm?type=devices&rid=6"`
STATUS=`echo $DOMOTICZ | jq -r '.status'`
if [ "$STATUS" == "OK" ] ; then
exit
else
sleep 5
DOMOTICZ=`curl -s --connect-timeout 2 --max-time 5 "http://192.168.2.173:8080/json.htm?type=devices&rid=6"`
STATUS2=`echo $DOMOTICZ | jq -r '.status'`
if [ "$STATUS2" == "OK" ] ; then
exit
else
sleep 5
DOMOTICZ=`curl -s --connect-timeout 2 --max-time 5 "http://192.168.2.173:8080/json.htm?type=devices&rid=6"`
STATUS3=`echo $DOMOTICZ | jq -r '.status'`
if [ "$STATUS3" == "OK" ] ; then
exit
else
sudo service domoticz.sh stop
sleep 8
sudo kill $(sudo netstat -anp | awk '/ LISTEN / {if($4 ~ ":8080$") { gsub("/.*","",$7); print $7; exit } }')
sleep 8
sudo service domoticz.sh start

My fault. After installing jq everything works fine.

Hi guys,

I used the script above for RPi2, my url and idx are working fine (getting status OK in a browser).
Jq installed and working.
Yet my domoticz is restarted every time.

Getting this when executing the script manually:

Code: Select all

pi@HOMECTRL01:~/domoticz/scripts/bash$ sh restart_domoticz.sh
restart_domoticz.sh: 4: [: OK: unexpected operator
restart_domoticz.sh: 10: [: OK: unexpected operator
restart_domoticz.sh: 16: [: OK: unexpected operator

Usage:
 kill [options] <pid> [...]

Options:
 <pid> [...]            send signal to every <pid> listed
 -<signal>, -s, --signal <signal>
                        specify the <signal> to be sent
 -l, --list=[<signal>]  list all signal names, or convert one to a name
 -L, --table            list all signal names in a nice table

 -h, --help     display this help and exit
 -V, --version  output version information and exit
Any idea what could be the issue?

Copy/paste to a windows computer?

Ok, figured out what the issue was.
I did not know that there are differences in 'sh' and 'bash' syntax. I am quite new to Linux.
Everything seems to be running fine now when executing as 'bash script name.sh' and not 'sh script_name.sh'
Thanks for sharing the script!
