MQTT binding with rpi

Hello,
i really appreciate some help about mqtt binding.
i’m trying communicate with my rpi to open a selected gpio.
To do so i use the mqtt protocol and it’s working fine (i installed mosquitto and try some terminal commands).

pi@pi02 ~ $ mosquitto_sub -t home/in/5
0
1
0

pi@tp01:~ $ mosquitto_pub -h 192.168.1.53 -t home/in/5 -m "0"
pi@tp01:~ $ mosquitto_pub -h 192.168.1.53 -t home/in/5 -m "1"
pi@tp01:~ $ mosquitto_pub -h 192.168.1.53 -t home/in/5 -m "0"
pi@tp01:~ $

Everything is working, i can hear the relay turning on/off (for an easy task i’m trying to make a switch on openhab and see if it’s working).

Items:
Switch mySwitch {mqtt=">[mymosquitto:home/in/5:command:ON:1],>[mymosquitto:home/in/5:command:OFF:0]"}
Sitemap:
sitemap default label=“Main Menu”
{
Frame label=“MQTT Test” {
Switch item=mySwitch
}
}

Openhab.cfg

No message sent to rpi and nothing on the topic (as you can see i’m sub to home/in/5)
Any ideas?
