MQTT & openhab

[Xander]

"20" is the node id of the sender. Your node id is 10. See: "send: 10-10-0-0 s=255,c=0,t=18,pt=0,l=5,st=ok:1.4.1"

"10" is the child id of this particular sensor. Your node has the child id's:

• "0" : send: 10-10-0-0 s=0,c=1,t=0,pt=7,l=5,st=ok:13.8
• "1" : send: 10-10-0-0 s=1,c=1,t=23,pt=3,l=2,st=ok:79
• "2" : send: 10-10-0-0 s=2,c=1,t=1,pt=7,l=5,st=ok:93.0

20-20-0-0
 |  | | |
 |  | | Id of Destination node
 |  | ID of next node
 |  Id of last node this message passed
 Id of sender node (origin)


s = child-sensor-id, 255 für "interne" Messages
c = message-type
t = sub-type
pt = payload-type (see MyMessage.h)
l = length of payload

@Xander Thanks for the answer.

For the auto-dealing with Ids, who did it ? Openhab or the gateway ?, or are the Ids fixed with (mysensor:MyMQTT/20/10/) ?

Thanks

[Xander]

The node id is from the gateway. The child id is given by you in your sketch.

[Totche]

@Xander Ok,

I just keep the gateway and the repeater.

repeater started, id 255
req node id

It seems that the gateway don't give an Id to the repeater

[Totche]

So back to serial gateway.

Are you sure that the gateway gives the Id ?
Ethernet, MQTT and serial gateways never send back ids to the nodes in my case.

When I force the Id, it's working and the gateway "shows" the values

repeater started, id 20
send: 20-20-0-0 s=255,c=0,t=18,pt=0,l=5,st=ok:1.4.1

[Xander]

I'm not shure what your configuration is. You have:

• a sensor node
• a repeater Node
• a serial / MQTT Gateway node
  3 nodes - is this OK?

Or is your sensor node the repeater too. I don't know if this is possible.

In case of a repeater node I'm not shure but I think the gateway is allways the "master" of all id's.

[Totche]

@Xander Thanks for the answer

For now, I have a MQTT controller, one repeater node with a BMP180 sensor (to do the forecast on a long time, as by definition the repeater never sleeps, with a modified sketch and a timer of 1 seconde), and an another node with temperature, luminance and hymidity sensors.

After some readings , i think that the gateway doesn't provide the Id, it's the role of the controller

=> in this discussion, you can read that, it's for Vera controller

Your going to want a controller in the long term. For testing you can either hard code the node ID in the sketch (you will want to flash the EEPROM clear sketch when you get a controller)

The reason your not seeing the temp on the gateway is because it doesn't get sent if there is no node ID.

Basically the node is asking the gateway/controller who am I and the controller isn't responding so it just keeps asking.

=> I use openHAb instead of Vera, and there is XXX.items file where you define the Ids for node and child

Number node1_temp  "Temp [%.1f °C]"     (node1,all)  {mqtt="<[mysensor:MyMQTT/20/10/V_TEMP:state:default]"}
Number node1_humid "Humid [%.1f %%Rh]" (node1,all)  {mqtt="<[mysensor:MyMQTT/20/11/V_HUM:state:default]"}

So I think that in this case, if the Ids are "constants" in openhab, they can't be randomly dealed by the gateway, and have to be fixed in each node

I just tested by giving Id to the nodes, and all seems correct

MQTT gateway

Re,

I tried to use MYSController without success

The IP is 192.168.1.234:1883 for the MQTT controller , but I can't read any values with the browser and MYSController.
And as you can see in the serial monitors, the nodes seem to discuss together.

I don't know how to check the communication with the MQTT gateway, apparently the problem comes from him
Any tips, ?

Thanks

[Xander]

I use a client ( MQTT.fx http://www.jensd.de/wordpress/?cat=50 ) to test the mqtt gateway. Please see my post: http://forum.mysensors.org/topic/953/how-to-know-the-node-ids-assigned-by-the-mqtt-gateway-to-the-sensors/2

With this tool I can see if the gateway is working and which id's are used. Then I configure OpenHAB accordingly.

[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 :(

[GuyP]

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....
