2 dallas temp + 4 relays



  • Has anyone had any progress on sensor node with mysensors + multiple dallas temp sensors and multiple relays combining the codes? Any help would be greatly appreciated. I have been playing with this for a little more than a week off and on. a push in the right direction would be great!
    Thanks

    Re: [Combining relay and temperature sketch](/topic/6782/combining-relay-and-temperature-sketch)


  • @mghaff i had also that problem, i have 4 relay's and 9 dallas sensors.

    if you want to look at it, i made a post of it at https://forum.mysensors.org/topic/9915/plant-watering-node

    prehaps it can help you.



  • @mghaff: please avoid double postings. It would have been nice if you'd at least have made a link to this post in the other one you did on that topic here: https://forum.mysensors.org/post/95894.

    @both:
    Imo you should implement a "non-blocking" code, nut just add a sleep or wait at the end of loop or just delete that. Otherwise most likely either your DS18B20 will not deliver any meaningfull measurements or you will not be able to controll your relays...
    Please have a look at https://github.com/mysensors/MySensors/blob/master/examples/EnergyMeterPulseSensor/EnergyMeterPulseSensor.ino as a base example how to implement non-blocking code (path: sleepmode false) or have a look in the sketch I linked to in the answer to the other posting: https://forum.mysensors.org/post/95901



  • @mghaff my sketch is working good, dallas and moisture readings are good, and i can control my relays.



  • @dzjr Didn't test that to be honest, but nevertheless, imho it is not a state of the art code design to use wait() nor is it best practice to use much hard-coded steps to do the same thing over and over. Rather use millis() for non-blocking coding and for-loops over comparable stuff, write to and read results from arrays. This keeps coding much easier to read and understand once you got the idea how it works.
    But what in the end counts: It works...



  • @dzjr I tried to use your sketch to get mine to work and it does not. I might just rebuild it all with new everything and try it again.



  • Would this be my blocking loop?

    void presentation() {
      // Send the sketch version information to the gateway and Controller
      sendSketchInfo("Fireplace interface", "1.1");
      //wait(LONG_WAIT);
    
      // Fetch the number of attached temperature sensors  
      numSensors = sensors.getDeviceCount();
    
      // Present all sensors to controller
      for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {   
         present(i+5, S_TEMP,"Fireplace Temp");
      //wait(SHORT_WAIT);
      }  
      for (int sensor=1, pin=RELAY_1; sensor<=NUMBER_OF_RELAYS; sensor++, pin++) {
       // Register all sensors to gw (they will be created as child devices)
        present(sensor, S_BINARY);
      //wait(SHORT_WAIT);
      }
    }
    


  • @mghaff Looks quite ok in the presentation() function.
    You do not need the "pin" variable in presentation, so you might shorten that to:

    for (int sensor=1; sensor<=NUMBER_OF_RELAYS; sensor++) {
       // Register all sensors to gw (they will be created as child devices)
        present(sensor, S_BINARY);
     }
    

    The "pin++" is needed in case you want to switch also the relays to a specific state. If you also want a completely flexible pin-assignment see sketch in https://forum.mysensors.org/topic/4847/multi-button-relay-sketch/33# as a very good example. There also the corresponding PIN is read from an predefined array (has some quite interesting button features also).



  • I tried to combine a couple other sketches and the closest I got was this one. But it still does not give me values for my Dallas temp. if I try each sketch separate they work fine and present fine with readings. I am a newbie and have luck, yes i call it luck cause my other sensors work just fine.

    My debug is

       DESCRIPTION
    
       Example sketch showing how to send in DS1820B OneWire temperature readings back to the controller
       http://www.mysensors.org/build/temp
    
       The cool thing about this temperature sensor (pun intended) is thay you can attach multiple Dallas temperature sensors outputs to the same arduino pin. They will all automatically be recognised as separate sensors.
    
       At the moment of writing (februari 2017) you need older versions of the Dallas and OneWire libraries. Please check the website or forum to see if this is still the case.
    
       Modifications by anonymous user so that it can now simultaneously function as a MySensors repeater.

  • Have a look at at least 2 things in the sketch:
    The for-loop(s) in presentation should be seperate ones for temp and relays.
    Imo you try to send out temperature using a different ChildID than in presentation().

    Additionally, -127 degrees indicates some wiring problems.



  • @rejoe2 said in 2 dallas temp + 4 relays:

    ost in the other on

    thank you for your tip to adjust the sketch, I am now working with a node for the water meter (partly based on your example of GITHUB) and I think I understand now what you mean.

    I will adjust the sketch of the example!

    I still have a wait (3000); in "void before" to start just after the gateway, because I use an RS-485 network.



  • @rejoe2

    To be honest I had to experiment a bit to get it working, but that is probably because I have little "experience" with Arduino code writing.

    But fortunately here at MySensors we get a lot of help and tips at this forum.



  • @mghaff

    in the Dallas temperature library there is also a test sketch, with that you can check of the Dallas sensors are working.

    My experience with multiple dallas sensors (more than 4) is that de 4K7 resistor not the right choise is, beter to use a 2K2 resisitor.

    maybe you can look at this forum post for that



  • @dzjr Good to hear your positive feedback, it's not always easy to decide whether to make some critical remarks or not.
    Imo, the wait() in before() might only be needed because of the transport-wait-flag, this is not related to RS485 as transport layer.
    I also use a 3.3kOhm resistor, the right value depends on some more variables than just the number of sensors.



  • This post is deleted!


  • @dzjr If i use the mysensors dallas temp that i use for my pool the sensors work just fine. If i use the relay sketch it works fine Alone. Whenever i combine these two sketches is when i have problems. I have been trying sketches that are working for others with no progress myself. I have even rewired twice. I am no programmer i took 2 classes in college but they r not helping me either.



  • @rejoe2 When i tried the for loops separate they don't show up at all in my serial. That was the only way to get them to present. I'm trying another sketch that looks more promising for me to build from but it as well doesn't show my temp. I get presentation but no reading.

    BTW thanks for the help.



  • @rejoe2

    I have again put a wait (500) in the loop, otherwise the sketch does not read any temperature .....
    between

    {
        //Dallas temperature sensoren
        // Fetch temperatures from Dallas sensors 
        sensors.requestTemperatures();
        // query conversion time and sleep until conversion completed
        int16_t conversionTime = sensors.millisToWaitForConversion(sensors.getResolution());
        
     
        wait(500);
    
        // Read temperatures and send them to controller 
        for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {
    

  • Contest Winner

    You calculate the conversion time, but you don't use it. So it makes sense that you won't get any readings without a wait, because the sensors don't get anytime to read. You should wait for the conversionTime before you read the sensors. Which is I'm guessing shorter than 500 ms, but I don't use Dallas temp sensors. So no expert on that.

    Absolutely right.
    Conversion time depends on resolution, max is 750ms according to data sheet.


  • Contest Winner

    @rejoe2 changing
    wait(500);

    to

    wait( millisToWaitForConversion );

    Should do the trick.
    But wait has an unsigned long as parameter and your conversionTime is a signed int16_t, you might need to cast it. Best to update the millisWaitForConversion to unsigned long as well.

    // This function helps to avoid a problem with the latest Dallas temperature library.
    unsigned long millisToWaitForConversion(uint8_t bitResolution)
    {
      switch (bitResolution) {
        case 9:
          return 94;
        case 10:
          return 188;
        case 11:
          return 375;
        default:
          return 750;
      }
    }
    

    But it's hard to help with only a fragment of the code. I'm guessing that the resolution doesn't change when your sketch is running. In that case I'd declare a global unsigned long conversionWaitDuration and initialize it in the setup. I honestly would never ever use a wait in a sketchs main loop though. I always use a none blocking wait which uses millis().

    But again hard to help with coding when you can only see a fragment of the code.



  • @theol

    i have uploaded the complete sketch at Github at here: link url)


  • Contest Winner

    @dzjr Would be so much easier to discuss it in Dutch 🙂

    What is the problem you encounter at the moment?

    I'm looking at the code, and just asking why you use so many unneeded blocks. e.g.

    { if (flow != oldflow) { // Theo <--- Removed the bracelet at the start of the line?
    ...

    That first starting bracelet ({) is not needed because the part that is being executed if the if statement evaluates to true is after the last bracelet. I'll see if I can clean up the code a bit for you. I'll add comments with what I've changed.


  • Contest Winner

    @dzjr here is the code with my comments. It compiles but I can't test it I use NRF24L01 and don't have any dallas temp sensors. I'll be cleaning up the code more like removing unused variables. Let's use that one for debugging purposes. Don't add anything else, because there's already a lot in it and it'll be harder to find the bug.

    Another MAX_ATTACHED_DS18B20 is 4. You only have 3 probes. This means that the 3rd and 4th will always report the same values.



  • @theol

    Yes, it is easier to discuss in Dutch, but that can not be followed for the rest.

    The only thing that does not work (well) is the reading of the temperature sensors after I turned off the "wait".

    Need to take a look at why the conversionTime does not work properly.

    The use of many blocks is mainly because I am a beginner, my third real arduino sketch.
    And I copied it partly from @rejoe2 his example, and tried to get it working, which also partly succeeded. partly by applying more blocks {} ....

    I can only learn from being very friendly that you help with making the sketch better.

    I would say,

    Neem een oliebol van mij!

    @dzjr If removed all unused variables and stuff. And the use of the bracelets was actually smart of you. Because you combined the different functions between them. The problem with it, is that is makes hard to read the code. So what I've done is I've made new functions of them outside the loop() and give them meaningful names. That way you have the lines of code, need for a specific function together in a method.
    Especially when you start learning how to program, using functions is a good practice. It will help you understand the code better.

    This code should work if it was only because the wait was removed. You need it in this case. It compiles, but I can't test it for you.

    Thanks for the oliebol 🙂 If you have any questions just ask. I'm glad that I could escape from the oudjaar-ellende 🙂 so my thanx for that.

  • Good work, @TheoL!
    Some additional remarks intented for @dzjr form my side:

    • Do you really want to start the node also when no communication to the GW is present? Otherwise disable "#define MY_TRANSPORT_WAIT_READY_MS 3000"
    • calculation of the conversion time could also be done once
    • using an array containing all of the sensor addresses makes code even more easy to read.

    For the later two things see https://github.com/rejoe2/MySensors-Dallas-Address-ChildID-Consistency/blob/master/Dallas_Addresses_Array_Solution/Dallas_Addresses_Array_Solution.ino (hope this still works, there had been some changes in the dallas-temp lib since I last used it myself).



  • @theol
    As a first of course a happy new year for all of you.

    @TheoL thank you for your work, that reads and programs a lot easier with their own voids, did not know that could work!

    I just loaded the net, only the temperature sensors do not come through, I'll tell you tonight if I can find it.

    The sketch is partly based on the MySensor-Garage Sketch from @rejoe2 , I copied the parts I needed (for the water meter), and for the temperature I copied it from another sketch which I had also used for another project. .

    As I said before, I am a beginner with Arduino, so I am very happy with this help and advice.

    Thanks again for your help



  • @rejoe2

    I thought that with #define MY_TRANSPORT_WAIT_READY_MS you could start the gateway first and then the node, I built everything with one 5 volt power supply, which is why I want the node to start later, before I now have a wait in void put down.

    I will take a look at the DALLAS scketch tonight or I can also use it in this sketch.



  • I have it working!

    In "void setup" I removed the extra lines , and then it worked \ o /

    // Theo: initialize the array with 0.0 as a value.
    for (int i = 0; i < numSensors && i < MAX_ATTACHED_DS18B20; i++) {
      lastTemperature[MAX_ATTACHED_DS18B20] = 0.0;
    };
    

    @ rejoe2 i removed the " wait transport" ,
    I tried your Dallas_Addresses_Array_Solution sketch, I think that maybe there are some library adjustments given, because it did not work directly (I got 00000000 as message).
    By the way, if I disconnect one sensor, another sensor is set it place at the controller, if it is connected again then it is back to the original ID.

    I have changed this line (line 114)

    float temperature = static_cast<float>(static_cast<int>((metric ? sensors.getTempC(dallasAddresses[i]) : sensors.getTempF(dallasAddresses[i])) * 10.)) / 10.;
    

    into this: (from the example sketch at the build section)

    By the way, if I disconnect one sensor, another sensor is set it place at the controller, if it is connected again then it is back to the original ID.

    This is where the array method is advantageous, the child-IDs of the chip addresses are fixed consecutively in the array, remove the chip from the line and it's place remains vacant until replaced.

    MY_TRANSPORT_WAIT_READY_MS

    This flag is - amongst a lot of other stuff - explained here: https://www.mysensors.org/download/sensor_api_20.
    So putting it to (default) "0" will keep the node looking for an uplink to the GW until that one is really available. As I don't want that (my nodes have some logic of their own, I want to work independently), I added that. But in case, it's just sensors and so on, I'd recommend to stick with the defaults.

    Wrt. to the "metric"-topic: Please do always have a look at the entire sketch. In my sketches, typically the metric variable is just initialized once in setup(). Eg. in the array-sketch you'll find that in line 97.
    If you are looking for a "easy" way to replace single sensors and keeping the original order of the others, have a look at this one.

    thank you, now I understand how it works, had it tried without a wait and then the transport did not start well, not all nodes were visible in the MySController, with "wait" in the setup all node's are visible in the controller at a complete restart (in case of power failure)

    The current method with dallas sensors also works well for me, not me to change the sensors, but to always give the sensors a fixed child id in Domoticz.



  • @dzjr Did you also try with the default value ("0") instead of 3000?
    I'm not familiar wir domoticz, but the need for another wait looks like a strange behaviour to me.



  • For low number of DS18B20 and if you have got enough free pins,
    I suggest use separate Arduino pin for each DS18B20.
    Then your code is absolute universal and you always know, which pin what measure.
    Do not matter, which DS18B20 you use.
    With your method, you must read each DS18B20 signature - hardcoded it, compile and flash.
    When sensor needs replacement due to malfunction - whole process again.



  • @kimot This consumes a lot of PINs, so it's a question what kind of trade-off you are looking for.
    As the 1Wire sensors have the option to address them correctly, I really like the advantage of reducing bus numbers. Just to remark: I also have at least one node running with 3 1Wire PINs - but each with a different timing 😁 . But if you are just worrying about replacement of single sensors, use something like that: https://github.com/rejoe2/MySensors-Dallas-Address-ChildID-Consistency. That only needs a restart between eacht replacement 😏 .
    Or add OTA features to your nodes...



  • @rejoe2

    Yes i tried is, i disable'd it in the sketch, but than the node's are nog presenting good to MYSController, only the update's are coming true but without the name's, only the first node give his client names.
    So ik just use wait in void setup.

  • @kimot
    In this node i can do that, i had copied it from another sketch i used 8 dallas sensors and i just copied that to this sketch.

    Perhaps i wil adjust the sketch and hardware.



  • First of all. thank you guys for all the help! here is what i found out. When testing my hardware i found that alone with the MySensors Dallas sensors sketch i would get readings from my Dallas sensors in serial and at controller. With relay sketch alone i would get All 4 relays working in controller and in serial. But combined no Dallas temp in serial or controller. I rewired with new sensors, Arduino nano, radio! Finally digging through my stuff i found a new board from a batch ordered 2 years ago, wired it up on bread board and wallah! Apparently the last batch or boards i ordered must have not passed quality or damaged in shipping!! Thanks again for the support!! On a way brighter note I have address's assigned to my temp sensors now on all my nodes and have learned so much more about the MySensors network!
