no mqtt connection my sonoff TH 16

Hello, a few days before i received my first sonoff devices.

I installed MQtt server on my raspberry pi 3 using this wiki https://wiki.fhem.de/wiki/Sonoff#MQTT_Server_einrichten

# Repo install:
wget http://repo.mosquitto.org/debian/mosquitto-repo.gpg.key
sudo apt-key add mosquitto-repo.gpg.key
cd /etc/apt/sources.list.d/
sudo wget http://repo.mosquitto.org/debian/mosquitto-wheezy.list
# or for jessie 
sudo wget http://repo.mosquitto.org/debian/mosquitto-jessie.list
sudo apt-get update
# mosquitto install and  client command mosquito_sub 
sudo apt-get install mosquitto mosquitto-clients

# MQTT Server Test
sudo service mosquitto status

with the result:

pi@raspberry ~ $ sudo service mosquitto status
● mosquitto.service - LSB: mosquitto MQTT v3.1 message broker
   Loaded: loaded (/etc/init.d/mosquitto)

Mqtt test on raspberry with ssh has worked fine with 2 ssh windows:

1. one: mosquitto_sub -h localhost -v -t test
2. one: mosquitto_pub -h localhost -t test -m "Test Mosquitto" Result in 1. window:

pi@raspberry ~ $ mosquitto_sub -h localhost -v -t test
test Test Mosquitto

In the webinterface of the sonoff console i get the following result:

00:00:00 APP: Project sonoff (Topic sonoff, Fallback DVES_1697CD, GroupTopic sonoffs) Version 3.1.2

In arendst software i have made the following changes:

#define STA_SSID               "SSID"      // Wifi SSID at home
#define STA_PASS               "password"  // Wifi password at home
#define WIFI_HOSTNAME          "%s-%04d"         // Expands to <MQTT_TOPIC>-<last 4 decimal chars of MAC address>



#define WIFI_CONFIG_TOOL       WIFI_WPSCONFIG    // Default tool if wifi fails to connect (WIFI_SMARTCONFIG, WIFI_MANAGER or WIFI_WPSCONFIG)
#define WIFI_CONFIG_TOOL       WIFI_WPSCONFIG    // Default tool if wifi fails to connect (WIFI_SMARTCONFIG, WIFI_MANAGER or WIFI_WPSCONFIG)

// Syslog
#define SYS_LOG_HOST           "Ip-Adresse-Server"

// MQTT
#define MQTT_HOST              "Ip-Adresse-Server"
#define MQTT_PORT              1883

"Ip-Adresse-Server" is the ip adress of my raspberry pi. This is the ip i use for ssh to communicate with my raspberry pi.

My sonoff still has no connection to mqtt on my raspberry.

Hope for your help.

Best regards, Kamil
