@atzohy welcome to the MySensors forum.
You are correct, except that you need 2x 47uF capacitors (one for eachnrf24l01+) and a 4.7kohm resistor (for the dallas temperature sensor). You'll need some wires as well.
There is no need to modify the temperature sketch.
Thank you very much for clearing up my questions! I will start to order the parts now and I hope I will be successful.

@atzohy great!
If you haven't already, you can also look at the generic buying guide https://www.mysensors.org/store/buying_guide
Yes, I used that one. It was very helpful. Now I'm waiting for the parts to arrive. Thank you again!
It's really amazing how cheap the sensors can be, if you build them by yourself.

Cannot automatic discover thing node
I'm not using the mysensors binding in openhab, i followed this https://www.smarthomeblog.net/diy-home-automation-sensors/ excellent tutorial and everything is working.
I didnt realise, that the warning was in the openhab log. Have you tried to define the node id in the sketch and add the sensor manually in openhab via a .thing and .item file like here described?

Hi, thanks for your reply. I've redone all the wiring and now everything works for me, even automatic discovery. I had edited my previous post, maybe you haven't seen it. But I still appreciate your help!
