4. MQTT & openhab

MQTT & openhab

  • Totche

    Hello,

    I'm stuck with openhab configuration => Embedded browser not available.

    Which versions have to be installed for java and eclipse ?

    I read the forums but it's obscure....

    Thanks

    EDit : It seems that it's not possible to have the designer working (some answers in other forums)

    Ok, so I leave aside the designer .

    I set-up openhab like => MQTT Broker gateway

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

    and for the items
    `
    Group all
    Group node1 (all)
    Group node2 (all)
    Group sketch (all)

    Number node1_temperature "Temperature [%.1f °C]" (node1,all) {mqtt="<[mysensor:MyMQTT/20/10/V_TEMP:state:default]"}
    Number node1_humidite "Humidite [%.1f %%Rh]" (node1,all) {mqtt="<[mysensor:MyMQTT/20/11/V_HUM:state:default]"}```

    The Id are set auto in the sketch

    For the sketch, the serial result is :

    repeater started, id 10
    send: 10-10-0-0 s=255,c=0,t=18,pt=0,l=5,st=ok:1.4.1
    send: 10-10-0-0 s=255,c=3,t=6,pt=1,l=1,st=ok:0

    send: 10-10-0-0 s=0,c=1,t=0,pt=7,l=5,st=ok:13.8

    send: 10-10-0-0 s=1,c=1,t=23,pt=3,l=2,st=ok:79
    Temperature hygro : 14.00C
    send: 10-10-0-0 s=2,c=1,t=1,pt=7,l=5,st=ok:93.0

    send: 10-10-0-0 s=0,c=1,t=0,pt=7,l=5,st=ok:13.9

    send: 10-10-0-0 s=1,c=1,t=23,pt=3,l=2,st=ok:85
    Temperature hygro : 14.00C

    So at this moment, everything seems to be ok

    openhab.jpg But when i try to select the first line (Tempearture, humidite....), i have a blue line

    I read somewhere that Id was autodealed (gw.begin(NULL, AUTO, true);) but my Id node is 10.
    Normaly should'nt be from 20 to 254 ?

    1. So what is wrong with the definitions ?

    2. In the items definition, (mysensor:MyMQTT/20/10/) what are 20 and 10 ?

    Thanks for any help

    1. The blue line disappeared when i reduced the text length

    2. id 10 and 11 => ClearEeprom : it's ok now

    But always request node Id for both nodes,

    Same question as above => In the items definition, (mysensor:MyMQTT/20/10/) what are 20 and 10 ?

    "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

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

    @Xander Ok,

    I just keep the gateway and the repeater.

    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

    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.

    @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,

    Sans titre.jpg
    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

    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.

    @Xander Thanks 😉

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

    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

    Sans titre1.jpg

    3- test.items

    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.

    @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.

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

    @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

    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.

    @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

    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 ????

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

    @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....
