2 dallas temp + 4 relays

[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.

@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.

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...

@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!
