Script NO1:
Below is a script which checks all sensors and switches available on my domoticz instance, and gives me information about last updates.
For example when a device is out of reach or battery empty.

Usage:

Outputs to console, or you can use it in check_mk monitoring.
(For the latter, create a script

vi /usr/lib/check_mk_agent/local/checkfrontdoor
chmod +x /usr/lib/check_mk_agent/local/checkfrontdoor
put in the script 
#!/bin/bash
cd /path/to/script/
./belowscript "Frontdoor" 300 checkmk

Code:

#!/bin/bash
#set -x
# after running once check stateseconds for names
if [ $# -eq 0 ]; then
echo "$(basename $0) - without options .. getting states"
echo "use $(basename $0) "Sensorname" seconds" for check
echo "Getting all states"
: > stateseconds
curl -s -i -H "Accept: application/json" "http://127.0.0.1:8080/json.htm?type=devices&filter=all&used=true&order=Name" | egrep "Name|Last" | grep -v HardwareName |grep -vi levelnames> states
sed -i 'N;s/\n/,/' states
now=$(date +%s)
cat states  | awk '{ print $3" "$4$7$8$9$10$11$12 }' | sed s/,,/,/g |rev | cut -c2- | rev | while read ; do
name="$(echo $REPLY | cut -f2 -d, )"
dater="$(echo $REPLY | cut -f1 -d, | sed s/\"//g)"
#echo $dater
seen=$(date -d "$dater" +%s)
#echo $seen
echo "$name $(( $now - $seen))" >> stateseconds
echo -n "."
done
fi
echo ""
if [[ ! -z "$1" && ! -z $2 ]]; then
checkold=$(cat stateseconds | grep "$1\"" | head -1 | awk '{ print $2 }')
total=$(( checkold - $2 ))
if [ -z $3 ] ; then
if [ $checkold -gt $2 ] ; then echo "$name lastseen longer than $2 seconds ago ($total sec)" ; exit 1 ;fi
else
if [ $checkold -gt $2 ] ; then echo "2 \"$1\" - Sensor older than $2 seconds" ; exit 1
else
echo "0 \"$1\" - Sensor age ok" ; exit 0
fi
fi
fi

Above to your Mqtt broker?

#!/bin/bash
# change 300 ( age below 5 minutes )
# and $2>=900 ( age above 15 minutes )
./agecheck.sh # Updates statefile
cat stateseconds | tr -d '"-/:"_' | sort -n -k2 | awk '$2<=300' | while read; do
sensorname=$(echo $REPLY | awk '{ print $1 }' )
age=$(echo $REPLY | awk '{ print $2 }' )
mosquitto_pub -h 10.1.0.17 -t sensorsage/$sensorname -m "$age"
done

Script NO:2
This is a mqtt speech script with caching sounds, speech generated for me by google

set msg.payload to “Doorbell”
and Mqtt topic to “speech/cmd”
