SOLVED: Sonoff 10A, MQTT and openHAB

[Sai_Khurana]

really looking forward to the solution of this problem of yours as i am facing the same problem. let me know

[ThomDietrich]

Well congrats

Now define a very simple testing item:

Switch MQTT_Test "Testing..." { mqtt="<[broker:testing/mqtt/topic:state:default]" }

With this one in place you should be able to do a first tst. Use your mqtt.fx to publish the Message “ON” to Topic “testing/mqtt/topic”. Check the log once again!

How did we do this just now? See: http://docs.openhab.org/addons/bindings/mqtt1/readme.html#item-configuration-for-inbound-messages

If everything works as expected you can now start to define specific items for your Sonoff. Once again, don’t bother with Espeasy. Go Tasmota:

• ITEAD Sonoff switches and sockets - cheap ESP8266 Wifi+MQTT hardware
• https://github.com/arendst/Sonoff-Tasmota/wiki/openHAB

@ThomDietrich

Check the log once again!

MQTT-Test works!

2017-09-05 21:44:11.170 [ItemStateChangedEvent     ] - MQTT_Test changed from OFF to ON

[ThomDietrich]

There you go That should be it. Let me know when further issues arise. Good luck!

@ThomDietrich

Let me know when further issues arise

i still cant control my sonoff thats my big issue

thats my MQTT Setting on the SONOFF

Thats the CONTROLLER-PUBLISH Field:

/%sysname%/%tskname%/%valname%

EDIT

I published on MQTT.fx
PUBLISH: “/Sonoff_1/GPIO/12”
MESSAGE: “0”

i can see the change on the ESPEasy

thats a little success, am i right ?

how do i make a working home.item out of it ?
thanks THOM!! <3

Hey @RiotMode,

you were honestly not the first one to have starting trouble with the MQTT Binding in the beginning of their openHAB adventure. I’ve taken what I’ve written above over into a Tutorial. Could you please check if anything is missing or not clear to a newcomer?

MQTT Binding (v1.11) Getting Started 101

After countless threads regarding initial configuration issues, here is a short guide on how to get started with MQTT, the MQTT binding and openHAB. This thread is a wiki article and can be improved by everyone. Please do! MQTT is a machine-to-machine (M2M)/“Internet of Things” connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. A few resources first: Read all you ever need to know about MQTT in the MQTT Essentials The openHAB MQT…

@ThomDietrich

Could you please check if anything is missing or not clear to a newcomer?

for sure - i will do now

I just would add (e.g MQTT.fx or something similiar )

1. Connect with the standalone client to the broker. (e.g MQTT.fx or something similiar )

6. Use the standalone MQTT client from before (e.g MQTT.fx )
Hit Send/>Publish<

@RiotMode

how do i make a working home.item out of it ?

That’s something you should be able to find out easily by yourself, with the links I’ve posted above… :-/

Probably something like

Switch LivingRoom_Light "Living Room Light" <light> (LR,gLight)
    { mqtt=">[broker:/Sonoff_1/GPIO/12:command:*:default],
            <[broker:/Sonoff_1/GPIO/12:state:default]" }

The first line defines the Item with all it’s details, the second defined the outbound MQTT topic, the third the inbound. Because you didn’t show all needed details I’m not sure if the topic for the latter is correct.

Honest, I can’t stretch it enough

[RiotMode (Philipp)]

@ThomDietrich

Probably something like

Switch LivingRoom_Light “Living Room Light” <light> (LR,gLight)
{ mqtt=“>[broker:/Sonoff_1/GPIO/12:command:*:default],
<[broker:/Sonoff_1/GPIO/12:state:default]” }

Man, i love you <3 - thanks for your help! really appreciate it.

i changed it that way:

Switch Sonoff6 "MQTT-Test" <light> (LR,gLight)
    { mqtt=">[broker:/Sonoff_1/GPIO/12:command:ON:1],
            >[broker:/Sonoff_1/GPIO/12:command:OFF:0],
            <[broker:/Sonoff_1/GPIO/12:state:ON:1],
            <[broker:/Sonoff_1/GPIO/12:state:OFF:0]" }

seems to work <3

ITS WORKING

[ThomDietrich]

Wonderful!

@ThomDietrich

Check the log to see if the broker connects successfully: http://openhabdevice-ip:9001

got stuck here!! site says refuse to connect

[ThomDietrich]

Then your mqtt.cfg is wrong… Compare with the settings used in the standalone client.

[Sai_Khurana]

what should i compare it with?

[RiotMode (Philipp)]

@Sai_Khurana

what should i compare it with?

for me, the mqtt.cfg looks fine, but i am the noob in here
now:

@ThomDietrich

Check the log to see if the broker connects successfully: http://openhabdevice-ip:9001

You should be seeing something like

2017-07-22 17:15:24.084 [INFO ] [penhab.io.transport.mqtt.MqttService] - MQTT Service initialization completed.
2017-07-22 17:15:24.089 [INFO ] [t.mqtt.internal.MqttBrokerConnection] - Starting MQTT broker connection ‘broker’

[Sai_Khurana]

can you send me a screenshot of the web page that you are looking at for this log. also tell me if i can see this log using ssh

[RiotMode (Philipp)]

@Sai_Khurana

can you send me a screenshot of the web page that you are looking at

@RiotMode

Check the log to see if the broker connects successfully: http://openhabdevice-ip:9001

for you i think its: http://192.160.0.14:9001
for me it was the ip of the raspberry ( 192.168.1.100:9001 )

[Sai_Khurana]

okay!!
i found some problems with my cfg file. like my if is 192.168.0.14 and not 192.160.0.14. i fixed it
now it looks something like this

#

#

also please send a screenshot of your current working mqtt.cfg file

@Sai_Khurana

a screenshot of your current working mqtt.cfg file

check your LOG! and REBOOT the device!

i tried to write i little tutorial for myself, so its partly in german, but maybe you can use it too
OpenHAB - Sonoff10A - Installation.pdf (847.3 KB)

[ThomDietrich]

Did you read my posting about the Tutorial? You’ll find all details, including how to view the log via SSH there:

Btw. viewing the log is a very fundamental thing when using openHAB. If you do not know how to do so, you should spend a few minutes in the documentation to learn about the basics of openHAB! http://docs.openhab.org

Good luck!

ITS WORKING

Heyho,

one little thing is not like it should - the SWITCH is sometimes on OFF - but the lamp is ON
The STATE is always correct ( Switch is on OFF, but STATE is on “1” )
Thats how i know about the Status of the Lamp.

How to make this work correctly ? - Any Ideas ?

THANKS
