Node Child and MQTT Subscribe

[Gambituk]

Hello. I am trying to get a connection working with mysensors I have the two devices communicating, but in order to make smaller steps, i want to assign a static node address to the remote node that is running dallas sketch for temp.

I read in other threads that :
gw.begin(NULL,25,false); is the way to do it.. I have tried two values, 5 and 25.

The serial output from the GW when i am running is like this.

0;0;3;0;9;read: 5-5-0 s=0,c=1,t=0,pt=7,l=5:21.3
0;0;3;0;9;read: 5-5-0 s=0,c=1,t=0,pt=7,l=5:21.2
0;0;3;0;9;read: 5-5-0 s=0,c=1,t=0,pt=7,l=5:21.1
0;0;3;0;9;read: 5-5-0 s=0,c=1,t=0,pt=7,l=5:21.0
0;0;3;0;9;read: 25-25-0 s=255,c=0,t=17,pt=0,l=3:1.4

0;0;3;0;9;read: 25-25-0 s=0,c=1,t=0,pt=7,l=5:20.8
0;0;3;0;9;read: 25-25-0 s=0,c=1,t=0,pt=7,l=5:20.9

1. Is the first value after read the node and the second the child?

2. If this is the case, and i wanted to check what was being sent to openhab via mqtt what would the topic be that i would subscribe to? (for example before i connect to the openHAB controller, i could use myMQTT to view the topic for troubleshooting?)

Thanks for any help

No, it is which node the message came from (last hop).
child-id is s=XXXX

[Gambituk]

AH! ok. that part seems clear now. Any idea's about the MQTT part? I am really looking for a way to get a handle on what is being sent. Been searching all day (and most of yesterday :/)

Thanks again,

Sorry.. I haven't much knowledge of the MQTT stuff.

In MQTT you can use wildcards so you can subscribe to everything published.

I am not familiar to myMQTT but I know mosquitto_sub and that can be quite handy for debugging.

[Gambituk]

I just found that exact same feature... mosquitto_sub -h localhost -v -t '#' or mosquitto_sub -h 192.168.0.7 -v -t '#'

That has totally helped me to see what is going on, and i can now see that openHAB section is working. but from the MQTTGateway sketch from the build page i get only something like this..

Should there be something happening to publish to mqtt? i kinda thought that was the point of this type of GW?

Thanks again for all the help so far. I can try to do a tutorial when i am finished from my noob perspective that might be useful for others.

I have been away for a while but it seams quite some of you are experiencing problems, I'll try to take a look at it. If you find any more details, please let me know!
