After some hours of sleep and refactoring everything, now I think I've managed to get everything working.
I have some problem wrapping my head around "forceTransmit" command and how it works.
Also, millis() is also something I have to learn :)
Here is the code if anyone finds it interesting.
What it does is measure soil moisture every hour and sends info (normal forkthingie).
Also reading every 30 seconds for temperature and humidity (si7021)
If humidity changes by 1 or temperature by 0.2 it will send info.
If no info has been sent it will force send info every 20 minutes.
3 Relays are there to power water pumps and a LED strip.
i have now semi-learned the use of functions, which is fun :)
cheers!
