2 dallas temp + 4 relays

[TheoL]

@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)

@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.

[TheoL]

@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!

[TheoL]

@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).

[dzjr]

@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.

[dzjr]

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)

float temperature = static_cast<float>(static_cast<int>((getControllerConfig().isMetric?sensors.getTempCByIndex(i):sensors.getTempFByIndex(i)) * 10.)) / 10.;

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.

[dzjr]

@rejoe2

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.

[rejoe2]

@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.

[kimot]

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.

[rejoe2]

@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 :grin: . 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 :smirk: .
Or add OTA features to your nodes...

[dzjr]

@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.

[dzjr]

@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.

[MGHaff]

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!
