topic3="myHome/debug"
user="guy"
password="kupelu9e"
broker="192.168.2.100"
lxterminal --display=:0 --title=$topic1 --command="mosquitto_sub -h $broker -t $topic1 -u $user -P $password" &
lxterminal --display=:0 --title=$topic2 --command="mosquitto_sub -h $broker -t $topic2 -u $user -P $password" &
lxterminal --display=:0 --title=$topic3 --command="mosquitto_sub -h $broker -t $topic3 -u $user -P $password" &
lxterminal --display=:0 --command="mosquitto_pub -h $broker -t "myHome/All" -u $user -P $password -m "status""
