I used the code and it worked well with the remote control.-
I can switch a LED (for testing purposes attached instead of a SSR) on and off.
If I want to switch the LED with a push button I fail.

This is what I have changed:

#define RELAY_PIN 4 // Arduino Digital I/O pin number for relay
#define RELAY_PIN_2 5
#define BUTTON_PIN 3 // Arduino Digital I/O pin number for button
#define BUTTON_PIN_2 7

And this is the serial output I get, after I press the button:

This is an ack from gateway

Hi and Thank you for the Board!!!

My question is, kann I user an usual old fashioned Light switch or must I buy a push button??

@gohan THANX!!!

@gohan said in Raspberry Pi with openHAB and nRF24L01:

MY_NODE_ID

with

#define MY_NODE_ID 1

it works now!!!

Thank you so much gohan.

Which FAQ or HowTo I have missed to know this?

Hi Gohan,

Thank you for the fast reply.
I thought, I gave an ID:

#define CHILD_ID 3

BY the way, Do the Gateway also needs an ID?
And where to Define?

Hello Forum,

I am using the latest openHAB ( 2.2.0-1) and Arduino IDE 1.8.5!
I installed the openHABian on the RPi and attached the NRF24 (with this description: https://www.mysensors.org/build/raspberry). I also installed the MySensors ans described in the link.

I also installed a programm to the arduino (https://www.mysensors.org/build/binary). The Arduino has also a NRF24 attached.

I have started the serial monitor in the Arduino IDE to see, what's happening in the Arduino:

This looks for me OK, but I am not pretty sure.
Now I would like to anyhow see on the RPi, that there is a connection. But since I am total newbie, I would like to ask the forum for help.

First question:
How can I see on th RPi, that there is a connection between the Arduino node and the RPi?

Second question:
How can I bring this into openHAB?

I would love to read meaningful answers.

Thank you
