sudo  /home/pi/domoticz/scripts/bash/deurbel.sh

doesn't work anymore

Code: Select all

sh  /home/pi/domoticz/scripts/bash/deurbel.sh

is working

Looks like the script is not executable anymore or the shebang line is wrong or missing.

fransiefrans · Post by **fransiefrans** » Thursday 14 July 2016 20:54

I still can't figure out what the problem could be.

It's for me not totally clear what is and what isn't working but looking at the posted info I would suggest to try in your lua script:

Code: Select all

os.execute("sh /home/pi/domoticz/scripts/bash/deurbel.sh &")

and from the commandline for the sudo version:

Code: Select all

sudo  sh /home/pi/domoticz/scripts/bash/deurbel.sh

from commandline result:

Code: Select all

pi@raspberrypi:~$ sudo  sh /home/pi/domoticz/scripts/bash/deurbel.sh

What happens when you use the url in a browser on your computer?
http://192.168.2.1:8080/camsnapshot.jpg?idx=1
Scratch that.. it looks like it downloads the image. So what is returning that HTML information?

In the deurbel.sh script, all needed variables need to be declarared/initialised

I don't understand what Jannl is saying. what should I change?

deurbel.sh:

Code: Select all

#!/bin/sh
echo "Hallo"

#SendMsgTo=$1
SendMsgTo=$TelegramChatId
#################################################################
IP="192.168.2.2"                              # IP address Camera
##########################################################
SnapFile=$TempFileDir"snapshot.jpg"
if ping -c 1 $IP > /dev/null ; then  # if IPCAM is online then:
     wget -O - http://192.168.2.1:8080/camsnapshot.jpg?idx=1 > $SnapFile
   sleep 2
   curl -s -X POST "https://api.telegram.org/bot"$TelegramBotToken"/sendPhoto" -F chat_id=$SendMsgTo -F caption="er wordt aangebeld" -F photo="@$SnapFile"
else
   curl --data 'chat_id='$SendMsgTo --data-urlencode 'text=IP-cam niet beschikbaar.' 'https://api.telegram.org/bot'$TelegramBotToken'/sendMessage'

when I type http://192.168.2.1:8080/camsnapshot.jpg?idx=1 in my browser, it is downloading the snapshot

fransiefrans · Post by **fransiefrans** » Thursday 14 July 2016 21:25

what do you mean with HTML information?

Code: Select all

sh  /home/pi/domoticz/scripts/bash/deurbel.sh

is sending me a snapshot to telegram

jvdz · Post by **jvdz** » Thursday 14 July 2016 21:35

Ok, so the Wget is working but the Telegram isn't. Just update the script from:

Code: Select all

   curl -s -X POST "https://api.telegram.org/bot"$TelegramBotToken"/sendPhoto" -F chat_id=$SendMsgTo -F caption="er wordt aangebeld" -F photo="@$SnapFile"

to this which will echo the commandline to the console:

Code: Select all

echo curl -s -X POST "https://api.telegram.org/bot"$TelegramBotToken"/sendPhoto" -F chat_id=$SendMsgTo -F caption="er wordt aangebeld" -F photo="@$SnapFile"
curl -s -X POST "https://api.telegram.org/bot"$TelegramBotToken"/sendPhoto" -F chat_id=$SendMsgTo -F caption="er wordt aangebeld" -F photo="@$SnapFile"

This should show you whether all components in the url are filled in correctly.

it used to work with sudo command. but even then the script never worked in domoticz on/off.

and in on/off action in domoticz, it appears in the log that it is executing the script but no snapshot is send.

As you can see the details of the environment variables are missing on the URL when ran with Sudo.

you will see the difference when you run: env | grep Tele
and: sudo env | grep Tele

Jos

fransiefrans · Post by **fransiefrans** » Thursday 14 July 2016 22:01

env | grep Tele is giving me telegrambotoffset, token and chat id
sudo env | grep Tele is giving me nothing

what is the difference between sudo and sh executing a file?

jvdz · Post by **jvdz** » Thursday 14 July 2016 22:09

When shelling it without sudo it runs with USER pi.
When shelling with sudo it runs with USER root.
So guess by default the script to set the environment variables (/etc/profile.d/DomoticzData.sh) is ran with the pi userid.

Why do you need/want to use sudo anyways?

Jos

fransiefrans · Post by **fransiefrans** » Thursday 14 July 2016 22:11

Ok that's clear to me now.
I don't need to use sudo. I need it to work with on/off action in domoticz

Are all the variables declared. They must be declared inside the proces space of the script.
For instance are you sure the scripts knows the value of $TelegramChatid?

Jannl was right. With perfect help from jvdz my issue has been solved. The solution was to alter the script by declaring the variables in the top.

Code: Select all

#!/bin/sh
TelegramBotToken="123456789:AAAAAAAAAAAAA_22222222222" 
TempFileDir="/var/tmp/"
SendMsgTo="12345678"
IP="192.168.2.2"                              # IP address Camera
##########################################################
SnapFile=$TempFileDir"snapshot.jpg"
if ping -c 1 $IP > /dev/null ; then  # if IPCAM is online then:
    wget -O - http://192.168.2.1:8080/camsnapshot.jpg?idx=1 > $SnapFile
   sleep 2
   echo curl -s -X POST "https://api.telegram.org/bot"$TelegramBotToken"/sendPhoto" -F chat_id=$SendMsgTo -F caption="er wordt aangebeld" -F photo="@$SnapFile"
   curl -s -X POST "https://api.telegram.org/bot"$TelegramBotToken"/sendPhoto" -F chat_id=$SendMsgTo -F caption="er wordt aangebeld" -F photo="@$SnapFile"
else
   curl --data 'chat_id='$SendMsgTo --data-urlencode 'text=IP-cam niet beschikbaar.' 'https://api.telegram.org/bot'$TelegramBotToken'/sendMessage'
