Wireless temperature transmission from multiple sources to one controller

Hello everyone,

Here is the last sketch I've made and the respective code for both the emitter (MAX6675 & nRF24L01) and the receiver (MAX6675 & nRF24L01 & Relay).

I've been reading the book "Practical Electronics for Inventors" (Paul Scherz) to get myself familiarized with the concepts involved in this project, along with several articles and posts found online. In spite of this, I'm hitting a wall with the complexity involved. I wold really appreciate if you could please check my sketch and codes and let me know if I'm on the right path. Also, I'm open for any recommended source to study.

Thanks,
Tomas
