MQTT Broker gateway
-
@Damme Hey man, thanks for the extensive documentation!
Would you mind if I split this post into its own topic? I think your MQTT broker deserves its own topic; let's reserve this thread for OpenHAB+MQTT related stuff.Update Split done!

So have I got this right.....?
This will mean that I can build an arduino with an ethernet port and a radio, and this will then plug in to an ethernet port and be what my other ardiuno sensors will connect to, and it will send everything to my Vera?
@Homer For Vera you should build http://mysensors.org/build/ethernet_gateway
MQTTGateway is a MQTT broker (server), used for mqttclient like openhab for example.

Ok. I was hoping that this device would enable me to have some of my sensors connected to ethernet so I can power them as well. Rather than sending information over wireless, they would do so via ethernet.
There isn't a way to do as I have described above, right?

@Homer I'm sorry but I don't think I really understand your question.
read http://mysensors.org/build/network
Each node (with sensors) talk wireless to A gateway, which then talks to a controller (in your case Vera) this can be via RS232 OR ethernet.If you have something that talks MQTT (like openhab) as a controller, then your choice could be sensors <-> MQTTgateway <-> openhab instead.

I can confirm it's working with UIPEthernet.h and the ENC28J60 module as well. You need to turn off debugging in MyConfig.h to make the code fit.

Maybe that was a little too fast - it starts up and starting OpenHAB finds the gateway and connects. When I reset a node it appears that the gateway crashes (OpenHAB reports disconnect) and only a reset of the gateway helps to get it to work again. Problem is it's hard to debug without debugging enabled due to code size :(

@ToSa if possible you could make a tcpdump over the mqqt port and I'll look at it. Also a serial dump from the node would be great

I did "sudo tcpdump host 10.0.1.99 -i eth0 -w dump.pcap" on the RPi that is running the OpenHAB runtime (10.0.1.6 is the IP of the RPi with OpenHAB / 10.0.1.99 is the IP of the MQTT gateway) and then did the following:
- power-on MQTT gateway
- start OpenHAB and wait until startup finished
- power-on node with DallasTemperature
The pcap file is attached (not knowing a lot about the protocol it looks like a series of keep-alive messages only and suddenly a connection reset): dump2.pcap
I do not see any messages arriving at OpenHAB... looking at the debug output from the node it appears that the "find parent" message is correctly handled by the gateway but the "node ID request" is not.

Can you compile with myconfig debug enabled, but define tcpdump disabled? or is it too big that way too? -
I'm currently busy implementing an mqtt client plugin, and i'm going to use mysensors for it's first predefined implementation so i have a couple of questions
I took a look at the api page and saw this in the mqtt documentation:
[MQTT_BROKER_PREFIX]/[NodeID]/[SensorID]/V_[SensorType]Does this means as example:
MyMQTT/[0-255]/[0-255]/[STRING]/[VALUE]OR this?
MyMQTT/[0-255]/[0-255]/[0-endvarindex]/[VALUE]- Are variable types defined by their index used or by name?
- Also it states it keeps track of node id's how are these reported by the broker, should the controller still hand out free id's?
[EDIT]
I currently do not have the hardware present to at least set it up to test and look at what exactly is happening.

[/EDIT]@John MyMQTT/[0-255]/[0-255]/[STRING]/[VALUE]
MQTT.cpp :
sprintf(&buffer[buffsize],"/%i/%i/V_%s", msg.sender, msg.sensor, getType(convBuf, &vType[msg.type]));note V_%s -> MyMQTT/[0-255]/[0-255]/V_[STRING]/[VALUE]
also note there is no trailing / before payload, as http://public.dhe.ibm.com/software/dw/webservices/ws-mqtt/mqtt-v3r1.html
http://mqtt.org/wiki/doku.php/topic_format
I choose not to have trailing slash, but if needed its easy to make it configurable.and get type translates from this list

@Damme
Clear!And how about the internal messages? Are these somewhat compatible with the Serial API? Like this one now has a "I_GATEWAY_READY" internal var, this one complies then with the "Started!\n" message?
Also about the presentation (if the node does it), are these also passed through?
I know it's a bit question banging... But i just want to do it right.

@John No worries! :)
Presentation is On Todo.. Or Rather To think About list is presentation . I dont do anything with that as it is (Just ignores it). I havn't had any good idea for that yet.Internal is nothing more or less, it connects and set a variable that it is connected. :) But sure, there could be transport for internal messages also.
I do have an experimental version there I can send internal messages to reboot node, reboot gateway and set clear read eeprom values. (over mqtt-protocol) but this s not finnished yet.. Ideas are welcome! -

Ideas are welcome!@John About Presentation ; My idea was that next version of the variable system I will either store some bytes in the MQTT gateway about what S_types to V_types, or hopefully the next protocol contains both those so the GW doesnt have to remember. And then add an extra directory to the MQTT path ( MyMQTT/[0-255]/[0-255]/S_[STRING]/V_[STRING]/[VALUE]

I think maybe it depends on the next protocol implementation. Personally i wouldn't mind if the full path mapping was /[0-255]/[0-255]/etc.. to keep (prog)mem print smaller (use the V_ and S_ array index values). It could leave space for more specific things or some extra gateway specific functions.
it would be nice if the mqtt gateway output was "cloned" to the serial output. Controllers should/could be able to map the S_ and V_ types internally. I'm not aware of the openhab config if that would allow this, or that such a setup would require a lot of coding at openhab side.
[EDIT]
It would be more difficult to read though if a path would only exist of numbers. But could also introduce easier maintainability in your library because you wouldn't have to keep track on type namings.

[/EDIT].@John That was my first aproach, and I might set a define configuration to choose if the MQTT gateway should translate or not. As you say, the footprint would be much smaller.
Might be next version of the MQTT, slectable address layout :)
