Convert to LUA, LUA Beginner

[straatm]

All,

I tried already a various number of options, surfed the forum but I always end up with not finding the correct information.
I try to learn LUA scripting so first of all I search for a beginners explanation of LUA scripting I am familiar with programming. But not with all the parameters and function calls in LUA.
If someone has a good startingpoint that would help me a lot.

And maybe someone is willing to convert the Blocky I present below to a LUA script for my reference. Maybe I can go from there to learn the LUA scripting.

Thanks for your help!
BR,
Marc

If you are only going to use LUA in the domoticz environment, you should investigate if dzVents is suited for you. The wiki is an excellent starting point for that.

https://www.domoticz.com/wiki/DzVents:_ ... _scripting

My experience is that it will make LUA coding much easier to do, -understand and maintain by hiding all the complicated structures under the hood. In the end it is pure LUA but an enormous amount of work is already done for you.

First steps in programming in general? What Waaren is saying is true. dzVents will be a lot more friendly then LUA. I got most of my scripts ported over to dzVents now.

That however does not answer your request. I can't give any guaranties that the Lua code below will work. I just wrote it reading your blocky info. DId not test it, don't have your setup. Tried to keep it as close to your orginal for learning purpose. Hope it helps.

Code: Select all

commandArray = {}

local timenow = os.date("*t")
local minutesnow = timenow.min + timenow.hour * 60
local dm0700 = 7 * 60
local dm2200 = 22 * 60

if (minutesnow > dm0700 and minutesnow < timeofday['SunriseInMinutes']) or
   (minutesnow > timeofday['SunsetInMinutes'] and minutesnow < dm2200) or 
   otherdevices['UitNax'] == 'On' then

   commandArray['Group:Buiten-Lampen'] = 'On'

elseif otherdevices['Laat-Thuis'] == 'On' and otherdevices['UitNax'] == 'Off' then

   commandArray['Laat-Thuis'] = 'Off AFTER 30'
   commandArray['UitNax'] = 'On FOR 60'
   commandArray['Group:Buiten-Lampen'] = 'On'

elseif otherdevices['Laat-Thuis'] == 'Off' and otherdevices['UitNax'] == 'Off' then

   commandArray['Group:Buiten-Lampen'] = 'Off'

elseif minutesnow < dm0700 or minutesnow > dm2200 and otherdevices['UitNax'] == 'Off' then

  commandArray['Group:Buiten-Lampen'] = 'Off'

end     

return commandArray

dzVenst is very simple. Look also on new module for compact and simple syntax

In this sytext script is very short. You can download and read about it here viewtopic.php?f=59&t=21914
