Thank You for Your answers. I will try to build network. So maybe I have to send informations from node1 to controller, but also to node3 using setDestination function. For now I have to start but I'm sure that it isn't end of questions.
Thank You very much.

Hi Guys, I'm really new in MySensors topics so I decided to write new post with questions.

I want to create small network using RS485. I know that I have to prepare gateway (for me: Arduino Mega) and 3 nodes (any other Arduino). In the future I will connect gateway to the Hassio system (as the controller).

For now I want to connect nodes with gateway to exchange informations between them. It means, for example that I want to measure something on node1 and send it to the node3. And of course I want to send data to the gateway to keep it in the controller (hassio in the future).

Questions:

1. Will my network work without controller (only gateway + nodes)?
2. It is possible to send something from first node to the other one?
3. If I connect network to the controller it will be possible to set any parameters from this controller?
4. What can I do first?

Thank You in advance.
