Hi,

I tested the script and when i start it it works fine. But when starting the script in cron, nothing happens. I can see the output.tx file is being updated but the info in the html page of domoticz is not updated. Also starting with sudo in cron doesn't help.
Does anyone know why ?

Try running it my way. You run in with Python command.
You only need two files in the folder (st2domo.sh and speedtest-cli)

Did you test it with the scripts i placed here.
viewtopic.php?f=21&t=13814&start=60#p103936

Then run sh /<path>/st2domo.sh and not with the python command.

Yesterday I even uninstalled my SickRage and Couchpotato to be able to uninstall and re-install the SynoCommunity Python package.
No luck on that end, only a lot of work.... :-(

Update:

I have installed python2.7 via ipkg, because I read the overflow problem was linked to python2.5.
Because python2.5 is a part of my firmware, I now have 2 versions installed.

So I edited speedtest-cli, the first line now reads:

Code: Select all

#!/usr/bin/python2.7
instead of:

Code: Select all

#!/usr/bin/env python
Problem solved.... at last!

In linux give the command echo $PATH and copy the result. In the script at the beginning enter:
PATH=PATH:(the result from echo PATH)

That did the trick for me.

Good luck.

One solution could be to replace spaces with TAB key.

For Synology for example you need to use a TAB between every character and NOT spaces.
My rule as example:

Code: Select all

*/30	*	*	*	*	root	sh /volume2/@appstore/speedtest/st2domo.sh
Must be:

Code: Select all

*/30[tab]*[tab]*[tab]*[tab*[tab]root[tab]sh /volume2/@appstore/speedtest/st2domo.sh
[tab] means press the TAB key, not typing [tab]

Remove all spaces and replace them with a tab.
Save the cronjob and don't forget to restart the cronjob!!!!!

I that is not working
Check the logfiles. Mabye you can find an error there.

Don't know what system you use but on most linux systems you can find it in: /var/log

Thanks for your answer but i have other tasks and they work fine. i'll try with tab key between every character.
when you said "don't forget to restart the cronjob" it means restart the crontab, i did this : sudo /etc/init.d/cron restart
For your information, i have a raspberry pi.

Correct. You can also.restart the rasp. For.rasp you can use spaces.

Try also.user root in the cronjob line

Did you add the path to the script as i wrote in this topic ? I think that is the problem.

it's not working.
when you said "Try also.user root in the cronjob line" you mean run the crontab with the root account ?

Did do adjust the script to your system. Ip - Passwoord - IDX etc.
Did you create st2domo.sh maby with notepad of wordpad. That can give problems with strange characters added when saving the file.

Place your script so we can see what you use.

Hi,

I use this script:

Code: Select all

#!/bin/bash

#setup
host=192.168.10.137
port=8080
username=mijn gebruikersnaam
password=mijn password
pingidx=27
downloadidx=28
uploadidx=29

# no need to edit
speedtest-cli --simple > output.txt
ping=$(cat output.txt | sed -ne 's/^Ping: \([0-9]*\.[0-9]*\).*/\1/p')
download=$(cat output.txt | sed -ne 's/^Download: \([0-9]*\.[0-9]*\).*/\1/p')
upload=$(cat output.txt | sed -ne 's/^Upload: \([0-9]*\.[0-9]*\).*/\1/p')

#output if you run it manually
echo "ping = $ping ms"
echo "download = $download Mbps"
echo "upload =  $upload Mbps"

curl -s -i -H "Accept: application/json" "http://$username:$password@$host:$port/json.htm?type=command&param=udevice&idx=$pingidx&svalue=$ping"
curl -s -i -H "Accept: application/json" "http://$username:$password@$host:$port/json.htm?type=command&param=udevice&idx=$downloadidx&svalue=$download"
curl -s -i -H "Accept: application/json" "http://$username:$password@$host:$port/json.htm?type=command&param=udevice&idx=$uploadidx&svalue=$upload"
I have made the sh file in windows with notepad++ and upload it with ftp to the rasp.
When I check the file with for example nano editor in SSH i see no strange characters.
