MQTT Client

[gus]

Hi!

First attempt to get this plug to work
My goal is to use this to connect to mysensors modules (http://mysensors.org).
I managed to publish events to a local mossquitto broker, and I can see the events on other clients. My only problem is right now to see the events on EG.

I subscribe to Topic "/mysensors/#" but it will never appear any messages. I managed to get messages to EG if I'll type:

Code: Select all

mosquitto_pub -h 127.0.0.1 -t /mysensors -m "messages"

but not:

Code: Select all

mosquitto_pub -h 127.0.0.1 -t mysensors -m "messages"

Is there a way to subscribe to a Topic without the "/" before topic?

Just put in # and you will subscribe to every topic

Sorry, already tested that, you then get an Exception:

Code: Select all

And if I use "/#" then it dosent crash, but nothing receives

I use version r1694 and your latest plugin:

Strange, it works for me but I also see your exception...a / should be needed I think...cannot explain why it works here

To understand, you say that if you publish to /mysensors and subscribe in EG to /# it works?

What is the problem using / ?


EDIT I see why the exception happens, I am actually expecting that your subscription has a /

[krambriw]

In EG, if you configure a subscription to a topic like /test you can use another of the actions to publish a message to the same topic /test and it should work. Now if you want to publish from Linux, you have to publish to the same topic

I must say that I'm quite a rookie with MQTT still... but in the parser that I use between mysensors and mosquitto I don't manage to add "/" before the topics name, it crashes then...

I'll find a way, this is fun, new building blocks form my automation jungle

[krambriw]

I have noticed that a / (slash) not is mandatory in general, it is my implementation that is this way (I read in the beginning somewhere and understod that a slash was mandatory). It would be good if you can find a way around so I don't have to modify the plugin

Added support for SwitchKing MQTT events

Since there is a new plugin for SwitchKing supporting MQTT, I have made an update of the EventGhost plugin to allow MQTT integrations between the two

Hi
I am also having no events in log...
I'm using on same machine as broker, so 127.0.0.1:1883.
Have tried:
#
#/
/#
/#/
and various combinations using my topics, but nothing in log.
Can you help?

EG 0.4.1r1700
using current version d/l today from http://krambriw.net/Release/MQTT%20Client/

[krambriw]

It is (in current version) mandatory to start with a slash for subscription to topics.

/# should be a good starting point

1) How and to what topic do you publish? (the topic has also to start with a slash)

2) New to EG? Check that the subscription really is running, open the plugin and check the list of running clients

3) Tick checkbox for all events?

Hi
I have mosquitto running on same pc, lots of mqtt messages running around.
I can see using MQTTlens that the topics are being sent.
I have unchecked the 'Log only assigned and activated events' in eventghost.
I tried creating a new topic with mosquitto_pub.exe but not showing in eg log with or without slash.
I have confirmed the subscription starts in the Plugin: MQTT Client entry in my autostart.
Any other ideas?

[mlava]

Scratch all that...
I now have it working, it was more about the format of the topic definitions on my side, not a problem with the plugin.
Sorry to have wasted your time! Silly me...

[krambriw]

No problem, good that you have it working now

Thanks!
