💬 Temperature Sensor

gewoonandre

Is it also possible to upload the example code to a Arduino Nano, and connect it via USB to a Windows PC with Domoticz?

Or will it only work with the radio modules (and extra gateway?)

gohan

I think you can use the serial gateway sketch and the sensor code in setup and loop

CurtisMack

Thank you for posting this project!

Could like to suggest a small change to the sketch. There are several posts out there about this not running with the latest DallasTemperature library. The call to sensors.millisToWaitForConversion won't compile because the method is not public. From another post I learned that this method is very simple and could be included in the sketch. I would suggest changing the line

int16_t conversionTime = sensors.millisToWaitForConversion(sensors.getResolution());

to read

int16_t conversionTime = millisToWaitForConversion(sensors.getResolution());

and add this function to the sketch:

int16_t millisToWaitForConversion(uint8_t bitResolution)
{
switch (bitResolution)
{
case 9:
return 94;
case 10:
return 188;
case 11:
return 375;
default:
return 750;
}
}

In any case, this might help the next person using this project.

I had some problems with Domoticz triggering an event based on a certain temperature. When using multiple DS18B20 it is a good idea to use the ID of the sensors to always get the same order of sensors. If one is not read, for example B of A, B, C then C becomes B. See: https://forum.mysensors.org/topic/4143/about-ds18b20-onewire for more info. You maybe need to adjust the sketch a bit for your number of sensors.

@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....

@Rene046 The solution is here:https://forum.mysensors.org/topic/4828/temperature-sensor/46

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).

Rene046

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));```

Rene046

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?

have you checked https://www.mysensors.org/build/debug ?

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!

gohan

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

I just tried this today but get an error. Here's the output.....

Arduino: 1.8.3 (Windows 10), Board: "Arduino Pro or Pro Mini, ATmega328 (3.3V, 8 MHz)"

In file included from C:\Users\captain\Documents\Arduino\MYS-HW-CH\MYS-HW-CH.ino:37:0:

This report would have more information with
"Show verbose output during compilation"
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.

skywatch

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!
