only one arduino to domoticz without radio
-
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)

Hi!
You can use the dev branch of mysensors at github. See this post:
http://forum.mysensors.org/topic/1978/power-usage-sensor-multi-channel-local-display/27

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...

I would suggest using git, but you could download a snapshot of the dev branch as a zip file from github if you want. But git gives you an easy way of keeping your local files up to date, which might be important, since the dev branch is not a stable release.
When you have the library downloaded somehow, have a look here, in this file:
It's the example for the serial gateway, which you want to use. Setup, add and use the sensors, where it says so. Check the other examples of sensors in the library, for how to do that. Note that this is not done exactly like in version 1.5.
In the roadmap for version 1.6 there's instructions on how to convert version 1.5 sketches to 1.6 (dev), if you already have sketches that you want to reuse:

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

I haven't tested it myself, but I think you can remove/comment all the defines for functionality you are not using, radio for example.
Look in the examples directory in the dev branch at github for examples on how to program your sensors/actuators.
For example, see this relay example:
https://github.com/mysensors/Arduino/blob/development/libraries/MySensors/examples/RelayActuator/RelayActuator.inoGo to the official arduino reference page, for reading about analog pin reads, and more:
https://www.arduino.cc/en/Reference/AnalogRead

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

Hi Nico
I am looking for such a sketch but did not manage to get it up and running.
Can you send me the one you created?
I hope to modify it to my needs.
Thanks!

Below the script I used.
I am trying to get the EnergyMeterPulsSensor working without RF GW but directly connected via USB./**
- The MySensors Arduino library handles the wireless radio link and protocol
- between your home built sensors/actuators and HA controller of choice.
- The sensors forms a self healing radio network with optional repeaters. Each
- repeater and gateway builds a routing tables in EEPROM which keeps track of the
- network topology allowing messages to be routed to nodes.

- DESCRIPTION
- The ArduinoGateway prints data received from sensors on the serial link.
- The gateway accepts input on seral which will be sent out on radio network.
- The GW code is designed for Arduino Nano 328p / 16MHz
- Wire connections (OPTIONAL):
-
- Inclusion button should be connected between digital pin 3 and GND
-
- RX/TX/ERR leds need to be connected between +5V (anode) and digital pin 6/5/4 with resistor 270-330R in a series
- LEDs (OPTIONAL):
-
- To use the feature, uncomment MY_LEDS_BLINKING_FEATURE in MyConfig.h
-
- RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
-
- TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
-
- ERR (red) - fast blink on error during transmission error or recieve crc error

And does it work?
