    @CurtisMack

    could you explain how to solve this ?
    I'm no pro, and wanted to use 1 single DS1820 in a sketch and also got same message about :
    int16_t conversionTime = sensors.millisToWaitForConversion(sensors.getResolution());

    Mysensors is hard hard nut to learn, specially because of a lot of changes in the newer version 2.1.0 ...(and im still learning to work with arduino software , i keep running often against old sketches i like to try as sample to use them in other sketches , (my way of learning) but than they dont work with latest version. because something changed.
    but i love the mysensors functions.

    p.s sorry for my bad english....

      I sofar got the sketch running and giving good data on serial and into domoticz

      i only could use some help with how to sent my Temperature in Celsius to domoticz to
      i tried to use:
      send(msgTemp.set(insideThermometer ,2));
      and
      send(msgTemp.set(tempC,2));

      both without luck, the first did transmit some data but wrong numbers
      second did nothing think because with this i done i does not know what address the DS1820 is on.

      Im learning every day something new....

      Maybe someone could help,

          @Rene046 Your sketch doesn't show either of the send commands you say you are attempting. This makes it difficult to determine why it wouldn't be working. I am relative new to all of this as well, and use Vera not a Domoticz. On the first version that is sending a message, what data is getting through? I would try putting the "send" command someplace in the code where msgTemp has already been set. Then just call send(msgTemp).

            hi

            Then i would have placed this in the loop>
            The error i get then is :'TempC' was not declared in this scope

            #ifdef MY_DEBUG
            Serial.print("DS1820 Temperature: ");
              Serial.print(tempC);
              Serial.println(" C");
            send(msgTemp.set(tempC ,2));
              
              Serial.print("Battery Voltage: ");
              Serial.print(batteryV);
              Serial.println(" V");
            send(msgbatt.set(batteryV ,2));```

              so far my result.

              had to use float TempC = 50.5 at the start
              but in my serial i get the right temperature,
              but using it in the loop gives me still wrong number 50.5 so gets not updated.

                    Hi,

                    Can someone push me into the right direction.
                    I followed the "tutorial" and setup a Serial Gateway. This seems to be running just fine.

                    Now i want to add a node with a temperature sensor.

                    Both are using the NRF24L radio.

                    On my node i get an errors in the serial monitor.
                    What did i do wrong?

                        Hi Gohan,

                        I did not know that page. Thanks for the push :+1:

                        I think i have crappy radio tho, because i switched it with anotherone i have and it started working....
                        Thanks!

                          don't tell me about crappy nrf24... I got a bunch of really bad ones that work but only for 5 meters max.

                            THis is MYS 2.1.1 installed so a bit baffled as to what is causing the problem, it should just work, right?

                            Anyone with any insight please let me know! :)

                              option enabled in File -> Preferences.

                              THis is MYS 2.1.1 installed so a bit baffled as to what is causing the problem, it should just work, right?

                              Anyone with any insight please let me know! :)

                              @skywatch just follow the instructions on the build page:

                              This example uses a modified version of the external DTH library, which is included in the MySensors external examples. Please install it and restart the Arduino IDE before trying to compile.

                                Thank you - that did it.

                                But it would be good to have that info in the file header too, just to call attention to it. Either that or a structured step-by-step tutorial so that things like this don't get left out.

                                At least it works now though, kul!

                                  really silly question.....so does create multiple sensors? so i would have temp1 temp2 or does it combine the value of both for an averaged temprature?
                                  the way i read it it would present mutiple sensors i think?

                                    It creates the sensors that you present during the presentation.

                                      appologies for the badly worded questions...the code in its example format....
                                      am i reading it correctly that it presents sensors based on the variable for number of temp sensors?

                                        It will present different sensros according to the #define MAX_ATTACHED_DS18B20 16

                                          Hi,
                                          I have only one sensor on the mini pro and I have this in the logs:
                                          2017-07-30 14:41:28.492 (Mysensor) Temp (Congélateur)
                                          2017-07-30 14:41:28.497 (Mysensor) Temp (Congélateur)
                                          2017-07-30 14:41:28.501 (Mysensor) Temp (Congélateur)
                                          2017-07-30 14:41:28.506 (Mysensor) Temp (Congélateur)
                                          2017-07-30 14:41:28.510 (Mysensor) Temp (Congélateur)
                                          2017-07-30 14:41:28.515 (Mysensor) Temp (Congélateur)
                                          2017-07-30 14:41:28.521 (Mysensor) Temp (Congélateur)
                                          2017-07-30 14:41:28.526 (Mysensor) Temp (Congélateur)

                                          Sleep time is set to 60000ms, why the time between 2 messages is around 5ms???
