Could use a bid help to get started

[Rene046]

Hi there,

Today i started with MySensor,
I installed Domoticz on an arduino.
I made MySensor gateway that runs on Domoticz Gateway Version: 2.1.0
then i took a nano and installed a DHT11 took a sample code and i can read in serial monitor the temperature.
I i am trying by using many sample codes for sending the dht11 data to domoticz
but almost with all sample codes i get messages
about :

exit status 1
no matching function for call to 'DHT::DHT()'

or that the code is not for the nano.

Is there one simple working sample so i can test if i can sent a bid of data into domoticz.

im getting crazy because simple code can be written into my nano but stuff related to my sensor ... i get all kinds of problems..

Sorry for my bad english im a Dutch guy.

Kind Regards Rene.

p.s. i hope once to get a weather station running with more sensors, but would be glad to get 1 thing working

@Rene046 - Hi and welcome!
no matching function for call to 'DHT::DHT()' means you are missing the DHT library. You need to install it from here: https://github.com/mysensors/MySensorsArduinoExamples

Thx for you fast answer,

i installed you links library, seems i had to overwrite because i already had those,during compiling i get....

Hi,

What i see also often is that Mysensor.h is used in a lot of sketches
and cant be found by Arduino's ide.

WARNING: Spurious .mystools folder in 'MySensors' library
H:\WINDOWS GEBRUIKERS\MIJN_DOCUMENTEN\Arduino\DHT22-1\DHT22-1.ino:2:22: fatal error: MySensor.h: No such file or directory

i am afraid i have done something verry wrong that nothing seems to be working here.

Installed arduino ide many times removed library's many time's but still no sketch with Mysensor works here.

Please please help

[mfalkvidd]

@Rene046 how did you install the MySensors library? Did you use the instructions at https://www.mysensors.org/about/arduino#installing-the-sensor-libraries ?

Where did you find the dht11 sketch? MySensor.h (without s before the dot) is from MySensors 1.x so it seems there is a mixup between different versions.

[Rene046]

jes i installed it like in your link.

Seems my sketch is then from an older version. because it uses Mysensor.h
I also tried changing it to mysensors.h but then allot of things go wrong while compiling

Maybe you could point me to a DHT sketch thats up-to-date ? for mysensor version 2.1.1
i installed.

Im totally new with mysensor, and now you told me i understand that lots of sketches on internet are old and dont work anymore.
Where can i find info about changes ?

i now am trying the sketch of this person
https://forum.mysensors.org/topic/3774/multiple-dht22-in-one-sensor-for-greenhouse-newbee-question/5

but he also seems to use old version, i see again mysensor.h instead of mysensors.h

hope for an answer....

[mfalkvidd]

@Rene046 many MySensors sketches are included with the MySensors library. You can find them in File->Examples-MySensors in the Arduino IDE

However, sketches that require external libraries (such as the temperature example which requires a MySensors fork of the DHT library) can not be included within the library. Therefore, they are available at https://github.com/mysensors/MySensorsArduinoExamples/archive/master.zip

[Rene046]

All those samples seems to work and compile perfect,

But there is no sample with an DHT sensor temp. and hum included. or do i overlook ?

[mfalkvidd]

@Rene046 in the MySensorsArduinoExamples zip file is examples/DhtTemperatureAndHumiditySensor and libraries/DHT

You'll need both those folders.

[Rene046]

should i unzip those inside the mysensor map or arduino ?

[mfalkvidd]

@Rene046 I am not sure, but try putting DhtTemperatureAndHumiditySensor in the Arduino sketch folder (My Documents\Arduino on my computer) and DHT in the libraries folder (My Documents\Arduino\libraries on my computer)

[Rene046]

ok done that, opened the sketch sample for dht.
compile and i get :

@Rene046 There are two DHT folders. Delete the DHT folder that didn't come from the MySensorsArduinoExamples zip file.

[Rene046]

ok now im left with this

[mfalkvidd]

@Rene046 see https://forum.mysensors.org/topic/5841/getconfig-was-not-declared-in-this-scope-v2-1-1-fixed/2
(change getConfig to getControllerConfig)

[Rene046]

thanks it works... i love you ..lol

why do they change basic commands.... this make it hard to use.......

Like this command and why make from mysensor.h mysensors.h.

i also looked inside domoticz and i got data

thank you very very much

[mfalkvidd]

@Rene046 the change from MySensor to MySensors is because the Arduino IDE requires the .h file to have exactly the same name as the library. That was not the case when MySensors was created, but happened some time in 2015 I think. So to comply with Arduino IDE rules, it had to be changed.

The reason for changing getConfig is logged at https://github.com/mysensors/MySensors/issues/736 but I am not sure why and the fix (https://github.com/mysensors/MySensors/pull/737 ) does not explain why either, but seems to be due to a mistake in https://github.com/mysensors/MySensors/commit/92cbd2ac8f49fe2f8cb25726e08aac9ecd597b84

[Rene046]

ok,

At least i can now experiment with other sensors for my weather station project.
i now all electronics are working, i saved this sketch and commented those changes.
Again thank you for getting me started.

[mfalkvidd]

@Rene046 you're welcome. Great that you got it working.

[Rene046]

can i ask another question....

Im trying to add a battery sense pin to the sketch. they use gw. commands, are those also changed in the new version ?they are not recognized....

They serail monitor shows me the voltage but how do i send it as and child to domoticz.

[mfalkvidd]

@Rene046 most commands were simplified in MySensors 2.0. If the example you found uses gw.send(), remove gw. and just use send().

[Rene046]

Thanks Mikael,

could i find those new commands somewhere

[mfalkvidd]

@Rene046 yes they are all documented in the api. https://www.mysensors.org/download/sensor_api_20
