Modem Status and SIM Balance info via EMAIL or SMS

Task:

Requirement:

Daily reporting for the Modem status and SIM balance via email (or sms)
In this example I had TELTNOKIA SERIAL Modem (Model: Teltonika ModemCOM/G10 Serial ) attached with Linux base system [Ubuntu 12.4].
This system had kannel/playsms installed which sends sms alerts for various events and can trigger different scripts upon receiving SMS with specific codes or instructions. I created this script which run daily in morning  sends email info / alerts for any issue related to modem and sim balance. on internet there might be some better guides or methods to do the same task, but this one fulfilled my custom requirement with my text.

At a moment its on a very basic level, later we will modify it if required further 🙂
Sharing this script, maybe some one will get benefit from it or improve it on a pro level.


 

Requirement:

GAMMU must be installed and must be configured with the modem. you should run gammu –identify to make sure its detecting  the modem.

 


 

Bash Script to do the job:

######################
cat /temp/checkbal.sh

#!/bin/bash
# Script to check Modem status and SIM balance via GAMMU and send email alerts accordingly.

# STOP KANNEL so that GAMMU CAN RUN

# Identify MODEM and output its result in tmp file
echo -e "Checking MODEM status"
gammu --identify > /tmp/modeminfo

# Look for Modem string , if not found give error and exit.
A=`grep TELTONIKA "/tmp/modeminfo"`
if [ "$A" == "" ]; then
echo -e "$CURDATE Modem NOT Responding.."
echo -e "$CURDATE Modem NOT Responding.." > $MAILFILE

# START KANNEL which was stopped earlier

exit 0
else

# If modem found, then execute USSD code to inquire Mobile SIM Balance in tmp file (FOR ZONG SERVICE)
echo -e "Modem seems to be responding OK"
echo -e "================================="
echo -e "Now executing USSD code FOR ZONG MOBILE SERVICE via GAMMU"
gammu --getussd *222# > /tmp/mobilebal

# Look for word insufficient in above output file, if found then give error and exit.
B=`grep insufficient "/tmp/mobilebal"`
if [ "$B" == "" ]
then

BAL=`cat /tmp/mobilebal  |awk 'FNR == 3 {print $8}' |cut -f1 -d"."`
echo -e "Balance & Modem both OK, Alhamdolillah"
echo -e "Balance & Modem both OK, Alhamdolillah" > $MAILFILE
echo -e "Balance is:  $BAL"
echo -e "Balance is  $BAL  RS" |cut -f1 -d"." >> /tmp/mail.txt

# START KANNEL which was stopped earlier
service kannel start

exit 0

# ELSE print modem and sim status
else
echo -e "Modem Reponding but ZONG SIM may have not enough balance"
echo -e "Modem Reponding but ZONG SIM may have not enough balance" > /tmp/mail.txt
/temp/sendEmail-v1.56/sendEmail -t $TO1 -u "ALERT: $CURDATE Modem Daily Report: $COMPANY  Modem OK BUT SIM have no Balance" -o tls=yes -s smtp.gmail.com:587 -xu $GMAILID -xp $GMAILPASS -f $GMAILID -o message-file=$MAILFILE  -o message-content-type=$CONTENT_TYPE
