MQTT & openhab

[Totche]

@Xander Thanks ;)

Very great link, now I can see what is sent.

1)-

2- The ip in MQTT.fx is the same as in openhab.cfg

mqtt:mysensor.url=tcp://192.168.1.234:1883
 mqtt:mysensor.clientId=MQTT

3- test.items

Group all
Group meteo //(all)
Group noeud_1  (meteo)
Group noeud_2  (meteo)
//Group sketch (all)

Number noeud1_temperature  "Temperature [%.1f °C]"    (noeud_1, all)  {mqtt="<[mysensor:MyMQTT/21/0/V_TEMP:state:default]"}
Number noeud1_luminosite   "Luminosite [%.0f Lux]"  (noeud_1, all)  {mqtt="<[mysensor:MyMQTT/21/1/V_LIGHT_LEVEL:state:default]"}
Number noeud1_humidite     "Humidite [%.0f Rh]"     (noeud_1, all)  {mqtt="<[mysensor:MyMQTT/21/2/V_HUM:state:default]"}

4- openHAB runtime

And finally...........................

nothing :(

PS : i don't see the repeater with the barometer, I need to dissociate them so one nano more :(

Did you restart openHAB after you entered the MQTT gateway IP address in the configuration file? You don't need to restart when changing items, or sitemaps.

You should check that openHAB has made a connection to the MQTT gateway.

netstat -an |grep 1883

root@openHAB:~# netstat -an |grep 1883
tcp6       0      0 192.168.40.201:42199    192.168.40.200:1883     ESTABLISHED
root@openHAB:~# 

Do you see it listed? If not restart the gateway, it should connect within a few minutes.

[Totche]

@GuyP Thanks for reply

I'm using windows 7, so I can't use your command, and see if connection is made

The IP in openHAB is set since the beginning, and I never changed.

[Xander]

... but "netstat -an" should work!

[Totche]

@Xander I have that

C:\Users\Totche>netstat -an|find "1883"
  TCP    0.0.0.0:1883           0.0.0
  UDP    10.10.10.170:61883    

:

[GuyP]

that shows you have a listener, but nothing connected!

Are you running the gateway on this PC? if so the openhab configuration should be localhost or 127.0.0.1:1883.

[Totche]

@GuyP Now I can see that

C:\Users\Totche>netstat -an|find "1883"
  TCP    192.168.1.13:25638     192.168.1.134:1883     ESTABLISHED
  UDP    0.0.0.0:61883          *:*

The last Ip 192.168.1.234 was out of range with the router definitions

But no more values in openHAB, pfff

[Totche]

And tonight, the weird is back

C:\Users\Totche>netstat -an|find "1883"
  TCP    0.0.0.0:1883           0.0.0.0:0              LISTENING

In openHAB.fx, I can see the msgs from the node, so I suppose that the ethernet connection is working

With MYSController, nothing displayed, no node network

With the serial, I can see the exchanges between node and the MQTTgateway

So what's wrong ? The Gateway, a port redirection ????

[tekka]

@Totche Just for clarification: MYSController is not compatible with MQTT gateways but with serial gw. .

[Totche]

@tekka Ah OK, it's better to know it, thanks; ;)

And I found the error this morning and it works great......

To create the configuration file for openHAB, I made a copy/paste of the Mysensors example., and I haven't seen it was a space character at the beginning of each lines.

I removed it, and it's working fine.now

So be carefull with the spaces, it was a stupid mistake and boring to find.

I have done this test 5 times, so I'm sure that it's the problem.

Thank you everybody....
