I'm so happy !!!!
That's working very fine. I made it create a temperature sensor over analog measurement !
Now time to go further ! I think ethernet shield I've just ordered will wait in the cupboard.

Thank you so much for your damned effective help

Hello and thank so much for all that.
That's (a little bit) clearer...

However, I can see in this sketch some radio definitions. Should I remove them as far as I am not using radio.

Could you tell me where to find sensor setup / presentation / loop for simple things (measuring voltage on analog x / commanding a relay on digital y ??

That's so nice helping me...

I am really about to give up. I checked other solution than mysensors (JSON over serialIP, I2C, MQTT....) but I am SOOOO bad in all that. When I read forums, I fell like I was trying to run before knowing to walk lol

Thanks for your answer.

How should i use that ? should I install git on my raspian ?? I'm so lost !
The exemple you point is so complicated...

Hello everybody,

I feel a little bit dumb asking that but I'm a real newbie in arduino, sketches libraries ans everything and I don't manage to do the simple thing I want to : using my aduino connected to rpi over serial usb with domoticz.

I don't need radio, my arduino is next to my rpi and i'd like to measure voltage from one analog pin and use it as a sensor in domoticz.

I read a lot about mysensors, gateway, nodes but I can't figure out how to manage my simple project.

Can only one arduino can be used ? (as a gateway without NRF)
Can I read analog and digital inputs ? command digital outputs ?
Is mysensors that I need or something else ???

I would be very glad to have a little help because I am about to let it go !!

Thank you so much (sorry for bad english)
