Switch on for 1 minute and off for 10 minutes

[daPeda]

Hello everyone,

how can I realise it in dzvents that a switch, which when a temperature of a sensor has < 20 degrees, is switched on via dzvents for one minute, then is switched off but only checks again in 10 minutes what the temperature is and then switches the switch on again for one minute and then again from the beginning?

All my attempts showed that either the switch was permanently switched on, or it was switched on and then switched off again after 2 seconds.

I would be pleased if someone could give me a tip.

Thank you very much!

Peter

Run the dZvents script every 10 minutes (using timer) and use switchOn().forMin(1) to switch on for 1 minute

Thanks a lot!
I thougt, that 'every ten Minutes' set in quotes was a synonyme for an function, i have to write by myself...

Code: Select all

timer = 
        {
            'every 10 minutes',
        },

got it work now..

Thanks!

Why use a dzVents script for that? You can set this behaviour (on/off after X seconds) on the switch property page.

You would have to change that to 'every 11 minutes' to make it go On for 1 and Off for 10 minutes!

You can not set timer for 11 minutes

[Kedi]

Yes, you can.
In dzVents set the timer to every minute and do calculation of the number of minutes from midnight, and then do a mod 11 on that number.

That is not "every 11 minutes".
I'm calling your method "dancing with a tambourine"/

Sorry for offtop.

You can maybe use the "retrigger" function in dzventz
this is an part of a script i use and you can customize

Code: Select all

local scriptVar             = '-=# PIR Woonkamer #=-'
local light                 = 'Woonkamer'                       -- change to name of your light/group
local Screens               = 'Screens'
local retrigger             = 'Retrigger using customEvent'
local minutesBeforeSunset   = 120                               -- xxx min before sunset

return
{
    on =
    {
        timer =
            {
            function(domoticz)
                return
                    domoticz.time.matchesRule('at ' .. domoticz.variables('UV_Sleep').value) or
                    domoticz.time.matchesRule('at '  .. minutesBeforeSunset .. ' minutes before sunset')
                end,
            },

          --devices = { Test, },
          
        customEvents =
            {
            retrigger,
            }
    },

    logging = { level = domoticz.LOG_ERROR, -- change to domoticz.LOG_ERROR when all OK
                marker      = scriptVar 
                },

    execute = function(dz)

        local Sleep         = dz.variables('UV_Sleep').value
        local light         = dz.groups(light)                      -- groups instead of device
        local Screens_WNK   = dz.devices(492)
        local Screens_BLOK1 = dz.devices(493)
        local Erker_gr      = dz.devices(603)  
	local Erker_kl      = dz.devices(612)
	local Screens_Deur  = dz.devices(605)
	    
        local PIR           = dz.devices(451)
        local lux           = dz.devices(454).lux
        
        dz.log('LUX = ' .. lux .. ' en verlichting ' .. light.name .. ' is ' .. light.state,dz.LOG_FORCE)

        if dz.time.matchesRule('between ' .. minutesBeforeSunset .. ' minutes before sunset and ' .. Sleep) and not(dz.time.matchesRule('at ' .. Sleep)) then 

                if lux <= 10 and (Erker_gr.level < 50 or Erker_kl.level < 50 ) and Screens_BLOK1.state ~= "Open" and Screens_BLOK2.state ~= "Open" then 
                    Screens_BLOK1.switchSelector('Open')
                    dz.log('Screens Blok 1 OPEN voor lichtsensor Lux <10',dz.LOG_FORCE)
                    dz.log('Script wordt opnieuw gestart in 5 minuten (regel 60)',dz.LOG_FORCE)
                    dz.emitEvent(retrigger).afterSec(300) -- try again 

                elseif light.state ~= 'On' then
                    dz.log('Script wordt opnieuw gestart in 3 minuten (regel 90)',dz.LOG_FORCE)
                    dz.emitEvent(retrigger).afterSec(180) -- try again
            end
   end
}

did u solve your problem? if u use a 10 min trigger u will miss every 1 min that the switch is on, like previously said, so the time between On cycles will only be 9 min. if u necessarily need a 10 min cycle, here's the simplest idea i can came up with:

Code: Select all

return {
	on = {
		timer = { 'every 1 minutes' },
	   },
	execute = function(dz, devices)
            
        	local mySwitch = dz.devices('yourSwitch')           -- replace yourSwitch with the name of your switch
        	local temp = dz.devices('tempSensor').temperature   -- replace tempSensor with your temperature sensore.
        	local time = os.time()						-- the time when the script is triggered
        
        	local switchOffTime = 600 					-- the time that switch need to be off in seconds  (600 seconds = 10 min)
        	local desiredTemp = 20 						-- the desired temperature
        
        	local lastSeen = mySwitch.lastUpdate.secondsAgo	--time the switch was operated last time
        	local checkTime = time - (time - lastSeen)			-- calculate when the switch was last operated 

        	if (temp < desiredTemp and checkTime >= switchOffTime ) then	--check if the temperature is under 20 and if 10 min have passed since the switch is last operated
            	mySwitch.switchOn().forSec(60).checkFirst()			-- switch is On for 60 seconds
        	end
	end
}

this script trigger every 1 minute and check the temperature and if 10 min have passed since the switch was last time actioned. if the temperature is strictly under 20 degrees and the time last update is 10 minutes then the switch is turned on for 1 minute.
u can also use as the trigger for the script the temperature sensor not the time trigger. but if u need the exact time between on state and the pause then u will need to think about how often the sensore is read and how is this affecting the time u check for the switch being off.

u should probably be a little more specific and clear with what u wanna accomplish. from how u formulated the problem in the first post, i kinda doubt that this is really what u want.

keep in mind that i'm just a beginner in this just like u so maybe a second opinion on this is a good idea
