💬 Temperature Sensor

Woeka

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.

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.

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?

gohan

It creates the sensors that you present during the presentation.

markjgabb

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?
