Could use a bid help to get started

[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....

@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

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 :

H:\WINDOW~1\Temp\arduino_modified_sketch_660970\DhtTemperatureAndHumiditySensor.ino: In function 'void presentation()':

DhtTemperatureAndHumiditySensor:85: error: 'getConfig' was not declared in this scope

@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

H:\WINDOW~1\Temp\arduino_modified_sketch_225110\DhtTemperatureAndHumiditySensor.ino: In function 'void presentation()':

DhtTemperatureAndHumiditySensor:85: error: 'getConfig' was not declared in this scope

   metric = getConfig().isMetric;

                      ^

exit status 1
'getConfig' was not declared in this scope

@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
