💬 Temperature Sensor

[toddsantoro]

@mfalkvidd OK. I have it compiling and uploaded to the nano. My config file looks like this now:

sensor 6:
  -platform: onewire
    names:
      some_id: outside
      mount_dir: "/mnt/1wire"

I get an error when I restart HASS on the Pi.

ERROR (Thread-6) [homeassistant.components.sensor.onewire] No onewire sensor found. Check if dtoverlay=w1-gpio is in your /boot/config.txt. Check the mount_dir parameter if it's defined.

I guess my question is do I need to define the mount_dir variable and if so is the one I have correct? And if it is correct do I need to create that directory on my Pi?

I also do not get any output in the Arduino Serial Monitor window. Not sure if I even should...

Thanks in advance for any help...

[mfalkvidd]

@toddsantoro I am not familiar with homeassistant so I have no clue unfortunately.

About debug output on the serial monitor: Debug needs to be enabled first. See instructions at https://forum.mysensors.org/topic/666/debug-faq-and-how-ask-for-help and https://www.mysensors.org/build/debug

Debug output is often essential when troubleshooting.

@mfalkvidd Thank you!!! I get this output in the serial monitor

Does this look OK? If so I will ask my previous question on the Home Assistant forum. You have been a great help and once I get one of these things down I will be able to help others:)

[mfalkvidd]

@toddsantoro yes that looks good.

The "st=ok:xyz" means message xyz was acknowledged by the destination node (in your case by the gateway)

[stingone]

No compile error but i cant see anything on the serial monitor. also the temp sensor burend out with a 4k7 resistor :S

[remis]

@stingone
Hi. The same issue for me . I solve it with : 38400 bauds configuration serial port ( instead of 115200 default value)
and i lowering the RF power output with low_pa enable: it confirms that I have some issues with power suppply.

good luck

It seems the DallasTempereture library is not a part of the default Library setup from Mysensors as of version 2.0? I tried to compile the above code, but I had to manually download DallasTemperature from GitHub first. Then OneWire was also missing. Adding these two libraries brought me a bit further, but I get a long list of errors connected to OneWire. What libraries should be used?

[mfalkvidd]

@bentrik the library is part of the MySensorsArduinoExamples, which can be downloaded at https://github.com/mysensors/MySensorsArduinoExamples/archive/master.zip

[Sealander]

Hi All, i'm also new here and into this. Like others i also ran into problems compiling this sketch, i tried al libraries mentioned in the posts in this thread, but no go. keep getting this error message:

In file included from C:\Users\Gebruiker\Desktop\My Sensors\MySensors-master\MySensorsArduinoExamples-master\examples\DallasTemperatureSensor\DallasTemperatureSensor.ino:37:0:

         ^

DallasTemperatureSensor:85: error: within this context

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

      exit status 1

within this context

Can someone help me with this problem? i have no clue at all and woud really like to build me a working sensor so i can hook it up to my Domoticz setup. thanks

hin this context

[stingone]

@Sealander

see solution above. Delete your dallas library and replace with the one above in the master zip file. That was the solution for me.

[bentrik]

@mfalkvidd Thanks for the feedback, It got me a bit further.
I have a fresh Windows Arduino 1.6.12 install, and I have download the MySensors Library 2.0 through the Library manager, and I've found MySensors.h and MyConfig.h under \Documents\Arduino\libraries\MySensors

I'm able to compile and upload the RelayActuator but quite a few of the library files seem to be missing in 2.0. DallasTemperature seem to be one of them.-But I struggled with DallasTemperature and some others.

I copied all the whole MySensors-1.5.4.zip library files to to C:\Program Files (x86)\Arduino\libraries, and I managed to compile, but I got an error message saying Invalid version found: 1.04
Then I tried to only copy the DallasTemperature and OneWire folder, and I had no errors.

-So I assume all library files the entire MySensors Examples catalouge are not ready in Libraries 2.0.

Anyways: The solution to get this sensor to work with Arduino 1.6.12, following the Download and API guide, adding MySensors 2.0 through the Library Manager, is to manually add:
\Arduino\libraries\DallasTemperature
\Arduino\libraries\OneWire\

-from https://github.com/mysensors/MySensorsArduinoExamples/archive/master.zip
-And not adding the whole structure.

Now I just have to find out how to make it speak to my serial gateway :satisfied:

[wendan]

I get the feeling it is possible to use more then one sensor parallel on port 3. I wonder if each sensor is being monitored? Am I right and do I need to alter or change something?

[wendan]

my feeling was right.... i just connected 5 temp censors it is working great

[Joseph Absher]

I am getting the error:

DallasTemperatureSensor.ino: In function 'void loop()':
DallasTemperatureSensor:93: error: 'getConfig' was not declared in this scope
     float temperature = static_cast<float>(static_cast<int>((getConfig().isMetric?sensors.getTempCByIndex(i):sensors.getTempFByIndex(i)) * 10.)) / 10.;

Does anyone have any suggestions?

[mfalkvidd]

@Joseph-Absher https://forum.mysensors.org/topic/5841/getconfig-was-not-declared-in-this-scope-v2-1-1-fixed

[Joseph Absher]

@mfalkvidd That worked. Thanks.

Hello,
I'm a beginner in home automation and I'm trying MySensor for the first time. My acctual configaration is a Domoticz on a Raspberry Pi 2B and a RFLink GW with a NRF24L01 module to try to measure with a MySensor probe.
I've building a temperature sensor with a DS18B20 sensor on a Official Arduino nano board and I can not run the sensor correctly.
The arduino serial monitor show these:

Someone could help me?

[gohan]

Did you set node ID?

[Vincent Lgrd]

Where should I put it? In arduino sensor code?

[gohan]

Yes, it's like #define MY_NODE_ID 2 and put it at beginning of the code
