Rules for dummies (to be exposed through OHcloud) from broadlink binding

[lipp_markus]

In general, you may want to start much simpler, for example, just pick one action and implement it.
And you may need to read this chapter a few times:

Rules

Quit a few of your current questions and inevitable future questions are handled there.

Some more details:

@lagging

I am struggling to envision whether one rule would trigger another and i’d end up in an infinite loop of light changes (ive tried to avoid it with item___postUpdate(___) but i feel very unsure about it

Here a direct link to a sub-chapter of above that explains the difference between update and Command: Rules | openHAB

@lagging

I don’t know how to have the system wait for half a second or so after the wall switch powers up the ceiling fans(they arent immediately operative when powered, and even z-wave sometimes varies in reaction speed)

That is a little more complicated, but here a good post about the options:

(OH 1.x and OH 2.x Rules DSL only] Why have my Rules stopped running? Why Thread::sleep is a bad idea

EDIT: While the general advice in this article still applies (i.e. it’s always worth while to make short running rules), the problem described in this article only applies to OH 1.x and Rules DSL in OH 2.x. In OH 3 and beyond, this is no longer a problem so if your rules stop running in any version of OH released in the last two years (as of this edit in 1/2023) this is not your problem. By way of explanation, in OH 3 each rule gets it’s own thread. It is no longer possible for a rule to starve…

@lagging

generally insecure about the syntax. does endif exist, is it used correctly,is while used correctly, do i need to transform something into vars and strings… etc … it’s the first time

Understandable, the docs are not the greatest, there is a beginner section in the docs, read this please and especially this overview: https://www.openhab.org/docs/tutorial/rules.html
This one here:

if item Luce_Dario_EXP.state !=OFF 
then 
item Luce_Dario_EXP.postUpdate(OFF) 
endif

will need to look like this:

if (Luce_Dario_EXP.state !=OFF)  {Luce_Dario_EXP.postUpdate(OFF)} 

Note: if there is only one command you want to execute you can omit the {}

Happy reading and please start slow and small. A last tip: read up on the use of logInfo this will help you understand what your rules are doing and if they are doing anything.

AND: use VS Code Editors | openHAB it will highlight all syntax issues for you.
