I would like to do some light switching on sunset. However i would like to change the minutes before sunset to a variable.

I guess i have to do something with function(domoticz) but i'm not sure how i combine that with the 'xx before sunset'

Could somebody point me in the right direction? I saw something like this:

active = function(domoticz) -- This function will be evaluated every minute by the dzVents system
myLight = domoticz.devices(myLightIDX)
return myLight.state == "On"
end,

but this is for active. But how do i check the xx before sunset?

Kan i do something like:

on = function (domoticz)
check variable
but how do i check the sunset time?

You could you use 2 scripts, connected by a persistent variable that holds the 'random number of minutes'
The first would run at 3:00 and generate a random number and store this in the persistent data
(i have not seen a random function in Dzvents) so maybe use a asynchronous http call. See dzvents documentation.
you could use this call:
https://www.random.org/integers/?num=1& ... in&rnd=new

Then when the random number is stored during the night the 2nd script would use the persistent global variable "RandomMinutes" in its timer section

return {
on = {
timer = { Random .. " minutes before sunset'' },

hope this helps or inspires a different solution...

Hello,

This works for me:

Code: Select all

return {
    active = true, 
on = {
        ['timer'] = {
            'every minute'
        },
    },
    execute = function(domoticz, dummy)
        
	-- get current time
	timenow = os.date("*t")
	minutesnow = timenow.min + timenow.hour * 60

    if (minutesnow >= timeofday['SunsetInMinutes'] + 30) then --(Make 30 a variable)
        light.switchOn()
    end
end
}

The first code below does what you describe. But do you want it ?
The active = section will be called on every device update and every minute. I've put a print in so you can see how often that is on your system.
On my system it is called 4 times /second on average

Code: Select all

local minutesBeforeSunset = 20  -- or any other number

return {
     active = function(domoticz)
              -- Just to give you an idea how many times this function is called
              print("in active = section with value " .. minutesBeforeSunset) 
              
              -- using dzVents variable
              return domoticz.time.matchesRule(minutesBeforeSunset .. " minutes before sunset" ) 
            -- or using a domoticz variable
            -- return domoticz.time.matchesRule(domoticz.variables("fancy domoticz variable name").value ..  " minutes before sunset")  
             end,
    
    on         = {      timer         = { 'every minute'  } },
           
    execute = function(dz)
        dz.log("I remember i should do something... ")
    end
}

My personal opinion is that the script below is better suited for your requirement.

Code: Select all

return {
    on         = {      timer         = { "every minute"  } },
     
    logging    =   {   level   = domoticz.LOG_ERROR, 
                       marker  = "beforeSunset"},    
                       
    execute = function(dz)
        local minutesBeforeSunset = 20  -- or any other number
        if dz.time.matchesRule(minutesBeforeSunset .. " minutes before sunset" ) then
            dz.log("I remember I should do something... ",dz.LOG_FORCE)
        else
             dz.log("nothing to be done now   ",dz.LOG_FORCE)    
        end 
    end
}

Kind of an old topic, but maybe useful for someone using DzVents 2.4 or newer:
What also might be a possible solution is to run a script let say 30 minutes for example that turns on the switch with a random interval of 15 minutes

So you get something like:

Code: Select all

return 
{
    active = true,

    on = 
    {
        timer = 
        {
            '30 minutes before sunset',
        },
    },

    execute = function(dz)    
        dz.devices('switch1').switchOn().withinMin(15)
    end
}

This will cause the script to run 30 minutes before sunset and will switch on the switch random within 15 minutes, so effectively between 30 and 15 minutes before sunset.

Maybe you want a lot of control, but isn't the randomness checkbox intended for this?
