LUA - few questions of new user

[Didytz 0]

Hi,

I am still trying to learn LUA. I tried to follow few examples from internet but I still don't understand few things, so would appreciate if someone could clarify me following:

 

1) Can I write and paste somewhere in my hub code like this:

Please login or register to see this code.

 

or I must follow   DECLARATIONS (Conditions/Triggers)    - >  ACTIONS

 

 

2) If I must use DECLARATIONS  /  ACTIONS is it allowed to put condition in action part.  If it is allowed what is format?

I try to control heating by opening/closing windows and want to turn on heating only if it was ON before windows were open and to keep it OFF if it was OFF before windows opening.

  Is this valid "ACTIONS" code:

Please login or register to see this code.

As I am not able to set variable like this. I try to get Walli output state into variable at the moment of the windows opening. If this is possible then I would not need condition in ACTIONS.

 

 

3) When I translate block scene to LUA, why I see "hub.*" instead of "fibar.*" as it is in every example.

 

 

Sorry for mix of all kind questions but I just can't progress in learning without clearing this.

no, don't use these HC2/HCL examples, i mean the trigger section. You have HC3L, so you must use the declarations->actions way. Of course on the action side, you might still check "who" run the scene, by checking the sourceTrigger, but that's different story (use search to find examples here in forum)

the getValue will return boolean value, the setGlobalVariable need string, you can see it:

type is string

type is boolean

thsi returns an error:

 

[26.09.2022] [18:37:23] [ERROR] [SCENE78]: (load):8: Assertion failed: Expected string

 

so the proper way is to convert the boolean to string

FIBARO is part of Nice S.p.A., there are other gateways using same firmware engine, like Yubii Home sold by

or

Therefore, to unifi the code, the fibaro.* has been changed to hub.*

 

Examples has been not yet updated, is actually not necessary to care, as the fibaro.* will be still executed (as backward compatibility)

Use the blocks to create rules, it’s much more easier than lua. ?
