Openhab MQTT Example
-
-
@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 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.

@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. -

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......

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.

@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. -

@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.
@John There was a problem with serial....1.6.1.jar it doesnt show this correctly;
ArduinoUpdate -> 0;0;3;0;9;read: 14-14-0 s=1,c=1,t=16,pt=0,l=1:0
14;1;1;0;16;0i think its related with baud rate for jar file because i saw these kind of things in terminal ����BO�"U��²e��B&��i�

@C.r.a.z.y. That's highly possible, or there was a wrong choice of encoding at the wrong moment.

Hi.
I have OpenHAB, MQTT and battery powered units (http://iot-playground.com/2-uncategorised/10-low-power-door-window-sensor). I cannot receive battery status in Openhab (other things from the same unit are transmitted OK). What is wrong?- I send: gw.sendBatteryLevel(batLevel);
- Number node4_bat "Bat [%.1f %%]" <temperature> (node4, GBattery) {mqtt="<[mysensor:MyMQTT/4/255/50:state:default]"}
I have seen somewhere that battery state is transmitted via '50'?!?
-
Hi. I have figured it out. It is presented as "mysensor:MyMQTT/4/255/V_:state:default". No number in current version from mysensors!!!
The next step was to edit MyMQTT.cpp: char V_50[] PROGMEM = ""; into char V_50[] PROGMEM = "50";. Now I get battery status via "mysensor:MyMQTT/4/255/V_50:state:default".So in conclusion I have answered my own questions and have solved them...
