Openhab MQTT Example

[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......

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;0

i think its related with baud rate for jar file because i saw  these kind of things in terminal ����BO�"U��²e��B&��i�

[John]

@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?

1. I send: gw.sendBatteryLevel(batLevel);
2. 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'?!?

[Hacker007]

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...

coming back to the initial issue, is there anyone that can post items and maps configuration to test the binary switch example of mysensors? my configuration is arduino uno+w5100 and mqtt gateway, opnhab on windows pc on the same network
