Multi devices eventor

I totally understand. I am by nature quite confused and will try to remedy it because you are a great help to me.

With each of your answers I learn a little more. You don’t try to teach me, you teach me.
Without you I would still be in my infancy. AND I have come a long way from then this first post Blynk-client invalid token

These projects are important to me, it’s my only activity because of my health.

I spent my day restructuring and simplifying my codes so that they were readable and easy to study.

so from this problem I just changed the pins of my relay to avoid using the one wire.
All my project is working well so far.

Now that my probes are working and that the sensors divisions (MASTER) send the values ​​to the relay devices (SLAVE) your term of hysteresis interests me. Because indeed when the temperature varies between max and max - 0.5 the order and relight, sometimes every three seconds.
It is true that for some system the number of engagement can wear out the contactors prematurely.

I did some research on the internet without really finding an answer. From what I understand the hysteresis is just a value that represents n - x. But I can’t find how to implement it in my code

and here is my new code which is cleaner and more functional (well I think, if there is something to improve don’t hesitate to tell me!)
