no mqtt connection my sonoff TH 16

[kamilo558]

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 00:00:00 Wifi: Connecting to AP1 HSHKH (XXXXXXXXXXXXXX) in mode 11N as sonoff-6093... 00:00:07 Wifi: Connected 00:00:07 HTTP: Webserver active on sonoff-6093 with IP address 192.168.178.29 19:00:36 MQTT: Attempting connection... 19:01:04 MQTT: Attempting connection... 19:01:21 MQTT: Attempting connection... 19:01:39 MQTT: Attempting connection... 19:01:56 MQTT: Attempting connection... 19:02:13 MQTT: Attempting connection... 19:02:30 RSLT: tele/sonoff/UPTIME = 1 19:02:30 MQTT: Attempting connection... 19:02:48 MQTT: Attempting connection... 19:03:05 MQTT: Attempting connection... 19:03:22 MQTT: Attempting connection... 19:03:39 MQTT: Attempting connection... 19:03:57 MQTT: Attempting connection... 19:04:14 MQTT: Attempting connection... 19:04:31 MQTT: Attempting connection... 19:04:41 RSLT: stat/sonoff/POWER = ON 19:04:48 MQTT: Attempting connection... 19:05:05 MQTT: Attempting connection... 19:05:23 MQTT: Attempting connection... 19:05:40 MQTT: Attempting connection...

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 -<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

Try to install the latest version first as 3.1.2 is an old one. Download from https://github.com/arendst/Sonoff-Tasmota

Enable more logging with option 3 (weblog 3) and see what MQTT has to tell.

It might be one of the codes below:

#define MQTT_CONNECTION_TIMEOUT     -4
-4: when connecting,
    try setting the version in PubSubClient.h to the older version 3_1
    // MQTT_VERSION : Pick the version 
    #define MQTT_VERSION MQTT_VERSION_3_1  <<- uncomment this line
    Mosquitto 0.15-2 apparently does not support the newer version 3_1_1.
#define MQTT_CONNECTION_LOST        -3
#define MQTT_CONNECT_FAILED         -2
-2: means it's failing to create a network connection to the broker.
    Have you checked one of the basic http examples to verify you have the network configuration and setup correct?
#define MQTT_DISCONNECTED           -1
#define MQTT_CONNECTED               0
#define MQTT_CONNECT_BAD_PROTOCOL    1
#define MQTT_CONNECT_BAD_CLIENT_ID   2
#define MQTT_CONNECT_UNAVAILABLE     3
#define MQTT_CONNECT_BAD_CREDENTIALS 4
#define MQTT_CONNECT_UNAUTHORIZED    5
 5: I found out that the error code 5 was from cloudmqtt " not authorised".
    I had setup a new user "ESP8266Client" in cloudmqtt with a blank password, I'm guessing this isn't the way to do it.

Can you tell me which file i have to use for an update over wifi?

[kamilo558]

Ok. I installed the newest version.

now i receiver:

22:55:15 MQTT: Attempting connection...
22:55:16 mDNS: Query done with 0 mqtt services found
22:55:24 MQTT: CONNECT FAILED, rc -2. Retry in 10 seconds
22:55:35 MQTT: Attempting connection...
22:55:36 mDNS: Query done with 0 mqtt services found
22:55:45 MQTT: CONNECT FAILED, rc -2. Retry in 10 seconds

[arendst]

And see above what -2 means: network problems.

I am getting the same error message when connecting to MQTT, all was fine prior to the upgrade.

The connection to RPI mosquitto works fine for me using commit b88ec7f5a99d4bb6b578de9f59631c922e772030 of june 19, 2017.
