Openhab MQTT Example

C.r.a.z.y.

I am also using openHab ;) but serial way

Marcus

Is there a big difference between serial and ethernet?

C.r.a.z.y.

@Marcus it works fine for me

Marcus

@Crazy Do u need Mosquitto?

I to have had this same problem using openhab and MQTT Gateway. I could toggle relays and such but could not receive any information back from the gateway things such as sketch info or versions. So I decided to pull from that and try PiDome. I like the way PiDome works with the Serial Gateway. Everything seems to be more dynamic. I did try PiDome with the MQTT Gateway and got the same results as with Openhab I could publish information to the gateway but couldn't receive for some reason. Would like to find out what could be happening myself. However right now I'm waiting on parts.

C.r.a.z.y.

@Marcus serial is working fine with piDome, openHab and Vera. No need for mosquito which i never installed and used before.

Marcus

Thank u for your answers.

I love the look of openhab. So i will try the it with mosquitto.

If it will not work then i will try pidome and serial gateway.

If i have new infos i will post them here!

Marcus

Good morning community.

Here is what i did now for installing mosquitto on my raspberry pi.

This infos are from here (http://jpmens.net/2013/09/01/installing-mosquitto-on-a-raspberry-pi/).

  curl -O http://repo.mosquitto.org/debian/mosquitto-repo.gpg.key

  sudo apt-key add mosquitto-repo.gpg.key

  rm mosquitto-repo.gpg.key

  cd /etc/apt/sources.list.d/

  sudo curl -O http://repo.mosquitto.org/debian/mosquitto-repo.list

  sudo apt-get update

  sudo apt-get install mosquitto mosquitto-clients python-mosquitto

Now mosquitto is running.

With:

sudo /etc/init.d/mosquitto stop

I can stop it.

With

sudo /etc/init.d/mosquitto start

I can start it.

But what to do now???
How do i connect mosquitto to my MQTT-Ethernet-Gateway?
How do i connect mosquitto to Openhab?

Please help!

MQTT-Ethernet-Gateway is mqtt brocker, not client :(

to connect mosquitto try use MQTTClientGateway http://forum.mysensors.org/topic/524/mqtt-client-gateway

Marcus

@b0rmann Please read the whole thread and tell me what to do now!!! I only want openhab and mysensors work together. But i want to use my mqtt-ethernet-gateway. Not the serial way.

John

@Marcus PiDome also supports the mqtt gateway next to the serial gateway, so no need to switch. As far as i know, but i'm not an openhab expert, it should work fine as a mqtt client to connect to the mysensors mqtt gateway.

See this thread for some examples: http://forum.mysensors.org/topic/303/mqtt-broker-gateway

The developer of the MQTT gateway has posted some examples in the above thread on how you should be able to use it.

Cheers!

Marcus

@John Thank u very much. I think i will stop with Openhab and give PiDome a try. it seems to be better described what to do to get it run.

In the thread u mentioned i looked for some examples but didnt get them to work and no one could help.

b0rmann

@Marcus mqtt client gateway is not serial way :)

i have mqtt-client-gateway + raspi (mosquitto + openhab + nodered)

John

@Marcus Wish i could help, too bad it doesn't work. Others are using it successfully as far as i know. Maybe different openhab version install. Well, let me know if there are any issues or help needed with PiDome.

@Marcus: Sorry I'm in a hurry so...
But what to do now??? -> is your broker really ok?

open two terminal windows on your Raspberry.
one window:

mosquitto_sub -t /test -v
second window:

mosquitto_pub -t /test -m "test message"

If it's all fine, the test message should show up in the first window.

How do i connect mosquitto to Openhab?
OpenHab -> mosquitto
If your still got the OpenHab sitemap from above, the swtiches 1+3 should be functional like desribed, switch 2 will result in an errormessage in the log (as "intended").

Reverse direction (mosquitto -> Openhab).
You may populate your broker with some messages for the given topic.
e.g. mosquitto_pub -t MyMQTT/20/255/V_SKETCH_NAME -m "fake sketch name"

How do i connect mosquitto to Openhab?
I use the serial Gateway connected via USB to my Raspberry and a little Node.js script.
If you are interested - let me know.

Marcus

Thank u anyway for your help @tboha . I think this is too much complicated. I tried ur last idea, but i got connection refused error. Really frustrating.... I want to see results. I hope pidome gave me faster results than openhab.

tboha

Connection refused means (in 99%) your broker is not up or you got the wrong address.
I supposed you to run mosquitto_sub/pub on the same machine your broker runs on.
On a different machine you have to add the host address like:

mosquitto_sub -h 192.168.1.10 -t /topic -m "message".

No - at last its not really complicated, but I think you had just a bad start. MySensors and OpenHab tend to start right out of the box - but you need the right box......

Marcus

Please stop helping me now. Now i have pidome and the first sensor is running after 30 minutes with my ethernet mqtt gateway ;-)

That is what i want. Maybe one day there are nice tutorials for Openhab. Thank u very much for trying to help. If i now start with mosquitto to get openhab run is the same as when i make a patch for a patch....

It seems that pidome has wait for me it is really nice and not much complicated.

This thread can be closed here.

@Marcus Try Tim's files and JAR file for serial openHab http://forum.mysensors.org/topic/655/serial-gateway-connection-to-openhab/2
I added a motion sensor and its fine.

John

@Marcus Good to see you have it working! The MySensors MQTT plugin and serial drivers are quite stable. Some parts of the server can behave a little strange, cause still in heavy development.
