MQTT Client gateway


  • Hero Member

    @GizMoCuz Can you elaborate a little on your rebuild? ie. what was the objective?



  • Could someone please post the latest working version of the MQTT Client gateway sketch?


  • Hardware Contributor

    Does anyone have a version of this reworked for the new 1.5 client? Looking through the MySensor class, it looks like a lot of the code in MyMQTTClient.cpp can be removed as it's now in the sensor class. I'd like to use this for my gateway as it's a much better system than the broker gateway that's in the standard library but it needs to support message signing and the newer 1.5 code base. If someone else finished this already I'll just use that, otherwise I'll start working on it. I have family coming in town so I don't expect to get much done in the next week but assuming that the MQTT code is working fine (I have no experience with that writing an MQTT client), it shouldn't take much work to refactor the client to use the new MySensor base.



  • I just did an adaptation. I removed the MyMQTTClient.cpp completely. It looks codewise more than the MQTTGateway. I am in the process of testing it.

    You can find it here https://github.com/tomkxy/Arduino.git in the branch MQTTClient.



  • @tomkxy Any updates to this? my setup has been running well for a long time, but i am itchy to see if it will survive with 1.5.. i know i should just leave it alone πŸ˜„ but i cannot help but tinker with it.



  • Well it seems to work. Only point I saw and don't understand is that the gateway tries to send a message back to the sensor which does not seem to be an ACK. See my post here http://forum.mysensors.org/topic/1782/gateway-is-sending-command-1-type-1-c-1-t-1-message-to-sensor but so far no feedback on that. Functional wise it works, at least with my test temp and humidity sensor.



  • Please help! This MQTT client gateway fails to compile. I use 1.6.5. IDE, 1.5 library. Applied patches as suggested by ntruchsess and still get this error:

    here https://github.com/tomkxy/Arduino.git in the branch MQTTClient.

    Did you have a look at my repository above? Functional wise it is the same adapted for version 1.5. I have it in use for quite a while now.



  • to tomkhy: your gateway sketch compiles, but Arduino runs out of memory (I use Nano with W5100 ethernet module, SOFTSPI enabled). It does fit with MY_SIGNING_FEATURE and DEBUG disabled, but I need debug - somehow it is not registering with MQTT server. Please tell me how to reduce memory footprint.



  • I am using this sketch with a Mega exactly because of that problem. If you post your MQTTClientGateway sketch I can have a look. If you use Mosquito as MQTT broker you may also post the Mosquito config file.



  • Many thanks to @tomkhy!
    I built my MQTT client with his code. No modifications were needed.

    BTW, Will this or any other code get included into the official MySensors library?



  • It is now in the Development branch.


  • Hardware Contributor

    Hi,

    can this run on ESP8266 (as wifi-mqttclient-gateway), too?
    Greetings

    Andreas



  • I don't know, you have to try it. What I can say that with signing support enabled it doesn't fit into the memory of a ProMini. I run it in a Mega.

    Looks like you have it working now, but just incase, Previously when I have had memory issues , I have upgraded my bootloader to use Optiboot which gives you a little bit more.

  • @ahhk
    Hello all, first post here and a bit new to the mysensors field.
    I also want to know the answer as to whether this will run on the ESP8266 as hope to run a wifi gateway.
    Thanks in advance! πŸ™‚



  • Also keen to run this on an ESP8266 would be a great for bridging.



  • OK. I've got the gateway to compile and get the following:

    I can ping the MQTTClinetGateway from another machine and I've confirmed Mosquitto is running OK with a series of pub/subs from other machines/devices and that side of things is working perfectly fine.

    I'm not seeing any of the above gateway readings publish to my broker. Thoughts?

    Cheers.



  • Following points to verify and check:

    • is the gateway connected to the broker. As far as I remember you can check that by subscribiing to Mosquitto status messages
    mosquitto_sub -v -t \$SYS/#
    

    If not check what the authentication method is mosquitto is. If it allows anonymous access make sure that "MQTT_AUTH_REQUIRED" is not defined in the MQTTClientGateway sketch. If username and password are set correctly.

    It seems that you are not using signing. So ensure that your MQTTClientGateway is compiled with the signing feature disabled. That are the two points I can imagine now provided that you are sure that you have of course a working ethernet connection.



  • I downloaded and installed the development branch and got the MQTTClientGateway running on an UNO with a W5100 shield (that I'm suspicious of, in terms of its reliability). The sketch runs great for a while publishing data to Mosquitto on my Mac Mini, but then stops responding after a while. I'm pretty sure the cause of the problem is the ethernet shield as it bombs out when running other sketches - the webserver one for example.

    I have a few of these ENC28J60 boards and I'd like to use one of those instead, but have had some problems.

    http://www.aliexpress.com/item/ENC28J60-LAN-Ethernet-Network-Board-Module-for-arduino-25MHZ-Crystal-AVR-51-LPC-STM32-3-3V/1956963721.html

    I notice in the MQTTClientGateway sketch that I should just need to comment out the one W5100 Ethernet.h library and substitute with the UIPEthernet.h one, but I tried that and had no joy. Does anyone have a working sketch based on the ENC28J60 that they could post, along with the wiring diagram to connect that board in along with any additional tweaks necessary to get it running on an Uno? Thanks in advance. Cheers.



  • Hi Guys,

    I get this:

    But still, canΒ΄t ping the gw. Double checked IP and Port, seems to be fine.



  • I've ordered a new W5100 module - this time the red mini W5100 board missing the SD Card slot to see if I have better luck. Still keen to see code for an ENC based MQTTClientGateway though, as this will take a while to arrive... πŸ˜‰



  • To developers of the MQTT client:
    I just tried the GatewayW5100MQTTClient in the latest development branch - it gives me "0;0;3;0;9;Radio init fail" error, while GatewayW5100 sketch works fine. What could be the reason? I noticed that the declarations parts in these sketches are rather different.
    My setup: ARduino nano clone + W5100 module + NRF24L01 radio. All wired as in the MySensors ethernet gateway guide ([http://www.mysensors.org/build/ethernet_gateway])


  • Admin

    For the W5100 SOFTSPI has to be enabled. I see that this is missing from the sketch..

    Try adding (coming from the normal W5100 sketch)

    // W5100 Ethernet module SPI enable (optional if using a shield/module that manages SPI_EN signal)
    //#define MY_W5100_SPI_EN 4  
    
    // Enable Soft SPI for NRF radio (note different radio wiring is required)
    // The W5100 ethernet module seems to have a hard time co-operate with 
    // radio on the same spi bus.
    #if !defined(MY_W5100_SPI_EN)
      #define MY_SOFTSPI
      #define MY_SOFT_SPI_SCK_PIN 14
      #define MY_SOFT_SPI_MISO_PIN 16
      #define MY_SOFT_SPI_MOSI_PIN 15
    #endif  
    
    

    I'll update the repository.



  • Hi, Hek!
    You are correct. except I also had to add these 2 lines and then radio worked:

    #define MY_RF24_CE_PIN 5
    #define MY_RF24_CS_PIN 6
    

    Pls fix the repo. Looking forward to seeing mqtt client in the master branch.


  • Admin

    Pushed to build server. Soon merged.

  • What is the MQTT message to switch MQTT client gateway into inclusion mode?


  • Admin

    Something like this should work...

    Topic: mygateway/0/255/3/0/6

  • Is this MQTTClientGateway in the dev branch only? I didn't see something like this in the 1.5 release/master.
    I would prefer to use my gateway as client, but I am not skilled enough to use the dev branch and work around resulting problems πŸˆ‚

    hmm is this repo still functional? with the signing_feature enabled i'm getting compile errors:

  • Hardware Contributor

    @dakky It is currently only in the Dev branch, yes.





  • Good afternoon gents!

    So I have been playing with openHab and an arduino as a mqtt gateway and this has been successful. The only thing I don't like is that the arduino does not seem to like multiple connections to the MQTT broker.

    My next step then is to use an MQTT broker (mosquitto) on the pi and then subscribe to this from the arduino. If I understand correctly, this is exactly what this thread is discussing.

    So - I have downloaded the codes and without changing anything, tried to compile. This fails with numerous errors. I have te latest libraries installed and to be honest, I am a little lost as to what is wrong. Before I post lots of error messages, are there any known 'tricks' to get the latest version working?

    Hopefully someone can help - Thanks guys πŸ™‚


  • Hardware Contributor

    @cowen71 - Could you please give us a little more information to help troubleshoot your issues.

    What ethernet module are you using? W5100? If so you need to makesure that you have enabled soft SPI for NRF radio as it doesn't like it being on the same bus. We also have to move the CE/CSN pins for the radio too. All this is explained inside of the sketch itself.



  • Hi Samuel,

    OK, I was hoping there was a known 'trick' to get things working, but maybe I was just dreaming. Of course, if not - much more information is needed!

    At the moment I am testing with a Mega2560 with an arduino ethernet shield attached. This has (and still does) work well with the mqtt gateway downloaded from mysensors after a few minor pin assignment changes.

    The problem I am having is that I cannot compile the mqttClientGateway code. I get errors. I have to be honest that whilst I had experience 20 years ago with PIC's and other uC's, I am incredibly rusty with C and completely new to Arduinos. So it is a steep learning curve currently. In this case, I would not be surprised if I have made a real schoolboy error!

    So what did I do?....
    At the moment I installed the PubSubLient library into the Arduino libraries file.
    I copied the code from here: https://github.com/ntruchsess/MySensors/tree/mqttclient/libraries/MySensors/examples/MQTTClientGateway
    creating the three files in my mqttClientGateway development folder.

    I changed nothing (accept target and com port and hit the compile button! This fails with the following error initially:

    sketch\MyMQTTClient.cpp:14:30: fatal error: utility/MsTimer2.h: No such file or directory
    #include "utility/MsTimer2.h"

    I modified the include text to: #include "MsTimer2.h"
    and tried to compile again again. The result is:

    My suspicion is I have a compatibility problem between library versions and/or the sketch I have downloaded. The radio stuff I can probably solve (hopefully) its the issues before that I am struggling with.

    Any advice would be appreciated.

    Cheers


  • Hardware Contributor

    @cowen71, from a glancing look over that post, i would expect the issue to lie within your libraries. Whether it be a version merging issue or just a general error in placements.

    I will put money on that you have your Arduino folder setup incorrectly when it comes to the libraries. I'll be honest and admit that i'm not too sure why you're getting your client sketch from ntruchsess rather than directly from the MySensors github/download page.

    Lets just run through it from the start on where to get your libraries placed, in theory they could be located anywhere as long as the files inside of the mysensors folder are in the correct structure. You firstly need to get the development version, I prefer to just go for the direct download off of the download Page. Once you have that downloaded you should have a .zip folder called 'Arduino-development.zip'. Once you have extracted that you need to place all of its contents (3 folders and 5 files) into your Documents\Arduino folder.

    I would do all of the above with a clean folder structure for the arduino folder, save any library confusions for the software. Then we need to go back into your gateway sketch and change your pin configuration like you need to.

    Come back with your findings πŸ™‚



  • Cheers Samuel,
    I will let you know. I am happy (actually perhaps not happy!) to admit the failures are purely down to me trying to get to grips with everything here.

    I also have just noticed that ruslan reported the same error somewhere above and so I will also look at the solutions that worked for him.

    I let you know what happens



  • OK so as you suggested - everything redownloaded and a new folder structure created. And actually, I get exactly the same problem. Incidentally, my other sketches compile no problem. Some written by me, some downloaded (e.g. Serial_Gateway, mqtt_Gateway). The only one I have a problem with is the mqttClientGateway.

    I see above that ruslan had exactly the same issue 7 months ago and then got it working. The answer that helped him was....

    Did you have a look at my repository above? Functional wise it is the same adapted for version 1.5. I have it in use for quite a while now.

    but this link seems dead now.

    I better stop for the evening before my wife files for divorce! I get back to this tomorrow!
    Thanks for the support so far.


  • Hardware Contributor

    @cowen71 Could you post your sketch for either me or a software contributor to see what is going on with it please. If you're certain that the error codes are the same as before then we can use the previous post as reference, if they're different in any way, please post the error codes again with the sketch πŸ™‚



  • The link mentioned by @cowen71 was put into a pull request which went into the development branch. However, the MQTTClientGateway has been reworked significantly in the development branch. The message structure is now similar to the serial gateway. I just completed a "migration" from that old version to the latest development branch version which worked perfectly, apart from RF issues I had.

    Thus, I suggest to use the latest version of the development branch.


  • Hardware Contributor

    @tomkxy, if he followed my instructions like he said he has, he should all being well be running the latest version of the development branch. I may be incorrect but i still feel there may be some sort of folder structure error going on here.



  • OK - I couldn't sleep and so I am back for a short time.

    So first I have to confess, I did not read the instructions from Samuel correctly and downloaded the Stable libraries rather than the development versions. I have corrected this. With the development libraries several of my other sketches will no longer compile - but lets not worry about that now!!

    Next - I could not find within the mqttClientGateway sketch within the downloaded development folder. In the case I am just having a blonde moment, could you tell me exactly where this is located please.

    Final question regarding the folder structures. I have the Arduino installation in the program files where it installs automatically, and then my Sketchbook is set up as follows..

    \Arduino\Hardware
    \Arduino\Documentation
    \Arduino\Sketch\libraries
    \Arduino\Sketch\mqttGateway
    \Arduino\Sketch\pondController (etc... - folders for other sketches)


  • Hardware Contributor

    @cowen71, so lets get to know where your sketch book is located. I may have wrongly assumed this in my last post. Could you go to your arduino IDE > file > Preferences. On that panel you should see the location of your sketchbook, the default will be in your Documents folder, within another folder called Arduino. This is now where all of the sketches should be located. So if we go there you should have a folder structure like I mentioned in my last post. At least for this instance, could you get the latest development branch of MySensors Libraries. If i remember correctly, the software guys here have redone the MQTT client gateway sketch in the development branch to now work properly.

    This is why i was asking what ethernet module you was using, because they have two mqtt gateway sketches now, one for W5100 (the one i use) and then one for ESP8266. These will be named appropriately for you to see. They also have a serial version in there too, which i have never used. Use the appropriate one for you, all instructions for pin changes SHOULD be inside, i may be wrong though.

    In regards to your folder structure again, you're using the program files directory. This is incorrect as this is simply where arduino installs itself. You do not want to be putting your sketches for arduino IDE in there (if the location for your sketches inside of the preference menu for arduino IDE states a different location). Where ever your arduino IDE states is the sketchbook, place your sketches/libraries in there.



  • Hi Samuel,

    Firstly the folder structure - my previous explanation was poor. Let me try again. Under Program Files I have the normal installation that is done automatically. So far so good I think.
    Under a separate dedicated folder (c:\cloudstation\arduino) I have the additional directories I mentioned above. So..
    \Hardware
    \Documentation
    \Sketch\libraries
    \Sketch\mqttGateway (for example)
    \Sketch\pondController (etc... - folders for other sketches)
    \Sketch\mqttClientGateway (I hope to have this!!)
    I had already correctly set the sketchbook location in the preferences. I "think" this is correct as installing new libraries seems to install them to the correct location.

    And I did find of course the examples folder and the 'GatewayW5100MQTTClient'. But I thought this was actually a sketch providing the framework rather than a complete functional mqttClientGateway. It certainly seems a little sparse!



  • @cowen71 The whole library has been completely refactored. Yes, the sketch looks sparse. You get all the necessary functionality by the define

    #define MY_GATEWAY_MQTT_CLIENT
    

    which is as far as I remember already in the sketch.

    And from what i remember, this then enables it to gather the code required from the files from the #include function. This is the beauty of mysensors layout, enables us to use very clean and easy to read sketches for the newbies to completely understand. This is half of the error your getting when it referes to that .h file that it cant find. That is some of the code needed to run this gateway sketch.

    This is one of the reasons i love MySensors so much.



  • Guys, firstly, Thank you. You have the patience of saints!
    Believe it or not, I am actually a Software developer/Electronics engineer by trade but PC based. The Arduino platform is a new experience for me and my previous uC experience is 20years old!

    I now have a working mqttClientGateway. I need to play some more - but first indications are that it is working well.

    My problems were a combination of bad folder structure and also bad combinations of sketches and libraries (desperately trying to play down the lack of experience factor here!!). Once I got this sorted, it started working.

    A huge 'High 5' to you guys. I owe you a bier or maybe 2!

    Not a question for this thread I know, but before I leave you in peace - what are you using for your Home Automation controllers? I have been playing with openHab and this seems to work well, but I have not really investigated the others.

    @cowen71, you seem to be an awful lot like me πŸ˜‰ I'm using that exact sketch for the gateway with a W5100, modified in an enclosure with incating LEDs on to show the communication. I too use OpenHAB and love it. However i'm yet to experiment with others. Drop me a message, i feel we could have some decent conversations!

    Glad you have gotten your gateway working, pleased it was such a simple solution!



  • I am using Openhab. I also did not investigate into a lot of controllers. What I like about Openhab is the powerful rules engine and the tons of bindings it support.
    If you are able to program possibilities seem to endless.


  • Hardware Contributor

    @tomkxy, it seems that openhab users all love it for the exact same reasons. They sure have a strong client base. Those that like it, love it. I've never tried any of the others and i don't have any inclination to. The only other controller i really like the look of is MYScontroller being created by the software smartass' here ;). When it becomes more feature rich I'll be trialing it for my home πŸ™‚



  • I'am trying to add a local DHT22 sensor but as soon as anything is in the loop(), the gateway stops to work.

    even if I delete the sleep() rows. Hasn't it to be wait() ?



  • Got it to work. Removed serial.print lines and changed sleep() to wait().
