Global variables and constants

[camillsg]

Hi! 

I am new to Lua and Logic Machine 4 (I do not have LM5), but trying to learn. 
I have a question I hope someone can help me with. 

I want to controll heating loads in my house, by turning these on and off to reduce peak power. 
I therefore need to define constants and variables that all scripts (resident, event and in user library) can find, I belive these are called "global". 
I belive the declaration of the constants and variables can be written like this: 

------------------Constants in the system (temperatures) ---------------------

T_s={
  comfort={kitchen=22, bathroom=24, hall=20},
  save={kitchen=18, bathroom=20, hall=18} 
}

--------Declaration of the variables in the system -----------

loads={
  vb={k=5, room='bathroom', ad='2/0/5', B=0, P=3000},
  vk={k=4, room='bathroom', ad='11/0/0' ,B=1, P=60, T=T_test.bathroom},
  po={k=3, room='kitchen', ad='11/0/4', B=0, P=800, T=T_test.kitchen},
  vf_gang={k=2, room='hall', ad='2/0/6', B=0, P=860, T=T_test.hall},
  vf_kj={k=1, room='kitchen', ad='11/0/2', B=0, P=15, T=T_test.kitchen}
  }


I have read something about storage.set(), but is this the only way to do it? If so, in what script? And I am going to use these values a lot, will I always have to write  storage.get()?
Or can I make a library in User Library and just define all constants and variables like above, and then they are "global"? 

Thank you for all help!
