@gohan I already tried it, but it didn't work.

Anyway, now it's working. I added an Arduino which acts now like the gateway. I don't have any idea why it was not working only with the Pi.

Thanks to everyone who helped me.

Thank you for your reply.

I have added a log, when #define MY_NODE_ID 2 is set.

Is there maybe a config file which I can also add?

I want to use pimatic as controller, but I think it does not make sense, to use it without a working connection, right?

Hello,
I have a problem with my setup.
My gateway is a Raspi 3 with NRF24L01+ and Raspbian.
My node is an Arduino Uno R3, also with NRF24L01+. The NRF24 is connected with a 16v 100µF capacitor (some persons told me, that it should work for my project).
Both are working with v2.1.1 of MySensors. I have checked the wires several times.
I'm using version 1.8.1 of the Arduino IDE.
So when I try to make it work with this tutorial: https://www.mysensors.org/build/humidity it seems to not get an ID from the gateway.
Even when I add #define MY_NODE_ID 2 it doesn't change anything.

Log from Arduino:

I'm searching the Internet since days about this problem, but I still not found any solution.

I would really appreciate your help. If you need additional information regarding my problem, please let me know.
Thanks a lot!
