DzVents script turning on dummy switches when power use is negative

[Wilpshaar]

Hi all,

Who could help me out with a DZVents script for turning on dummy switches when power is negative? Seems blockly what I use can't work with negative numbers, don't get it work. Can someone create 2 Dummy switches called 'Dummy1' and 'Dummy2'. Then, if power is negative -750W switch on Dummy 1 and if power is negative -1500W switch on Dummy2. Of course is power becomes lower then -1500W Dummy2 should turn off and if lower then -750W Dummy1 should turn off. Who could help me out! Of course this is used for swithing on a 2-stage boiler. I power it on now telling power is <1 Watt and if solaredge is >1500W. But I want to be able to h[/img][/img]ave a simple script which can turn of 2 switches when power is -750 and -1500W (as example).

Blockly else-if is not really an else-if like you might be used to from other programming languages. Those else-if statements will all just be executed sequentially and tested. When true, the set statement will be executed.

So in the example:
Suppose power is -1000, then
First dummy1 will Not be switched on.
Second dummy2 will be switched on.
Third dummy one will be switched off.
Fourth dummy2 will Not be switched off.
So in the end dummy2 is on.
Is that what you want?

Suppose power is -500, then both dummy1 and dummy2 will be switched on (because > -750 and > -1500)

But if power is +500, then also they will both be switched on.

etc etc

So you need to add a few extra tests with and/or logic.

I've setup quickly a simple script for you.
Not sure it will work, but give it a try.
Change the device number to your devices and try it.

Code: Select all

local scriptVar     = '-=# Switch Hal #=-'

return
{
    on =
    {
        devices =
        {
            123,      -- Change the name to your device
        },
    },

    logging = { level = domoticz.LOG_INFO, -- change to domoticz.LOG_ERROR when all OK
                marker      = scriptVar 
                },
       		 	    
    execute = function(dz, device)
        local Stroom   = dz.devices(123) -- Change the name to your device
        local Dummy1   = dz.devices(234) -- Change the name to your device
        local Dummy2   = dz.devices(345) -- Change the name to your device
    
       if Stroom > -750 then
            Dummy1.switchOn().checkFirst()
            dz.log('Dummy 1 On', dz.LOG_FORCE)
        elseif Stroom > -1500 then
            Dummy1.switchOn().checkFirst()
            dz.log('Dummy 2 On', dz.LOG_FORCE)
        elseif Stroom < -750 then
            Dummy1.switchOff().checkFirst()
            dz.log('Dummy 1 Off', dz.LOG_FORCE)
        elseif Stroom < -750 then
            Dummy1.switchOff().checkFirst()
            dz.log('Dummy 2 Off', dz.LOG_FORCE)   
        else
            dz.log('Geen actie nodig ', dz.LOG_FORCE)
        end
    end
}

Thanks PAtrick, I just ready your reply now, I have the following now and see how it goes, will let you know,

Meaning should be;
If power use -250W turn on Dummy 1 (if more then -250 then switch off)
If power use -500W turn on Dummy 2 (if more then -500 then switch off)

This is for turning on or off 2 heating elements in a boiler, just how much power is consumed,


local scriptVar = '-=# Switch Hal #=-'

return
{
on =
{
devices =
{
Stroom, -- Change the name to your device
},
},

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

execute = function(dz, device)
local Stroom = dz.devices(Stroom) -- Change the name to your device
local Dummy1 = dz.devices(Dummy1) -- Change the name to your device
local Dummy2 = dz.devices(Dummy2) -- Change the name to your device

if Stroom > -250 then
Dummy1.switchOn().checkFirst()
dz.log('Dummy 1 On', dz.LOG_FORCE)
elseif Stroom > -500 then
Dummy2.switchOn().checkFirst()
dz.log('Dummy 2 On', dz.LOG_FORCE)
elseif Stroom < -250 then
Dummy1.switchOff().checkFirst()
dz.log('Dummy 1 Off', dz.LOG_FORCE)
elseif Stroom < -250 then
Dummy1.switchOff().checkFirst()
dz.log('Dummy 2 Off', dz.LOG_FORCE)
else
dz.log('Geen actie nodig ', dz.LOG_FORCE)
end
end
}

HI PAtrick,

I am afraid nothing is happening? See nothing in the log, see no dummy switches changing, I could test when I remove the '-' (minus)

Thanks in advance, thanks for helping,

HI PAtrick,

Thanks in advance, thanks for helping,

Is the script being triggered by the device
Chamge otherwise the devicename for the IDX number

Please use CODE instead of image for script

HI Patrick, for testing I use in the evening now of course positive power consumption but we could check working of script. Bit more happening now, have error in log "<name > expected near '97'. Any idea? Thanks!

local scriptVar = '-=# Switch Hal #=-'

return
{
on =
{
devices =
{
97, -- Change the name to your device
},
},

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

execute = function(dz, device)
local 97 = dz.devices(97) -- Change the name to your device
local 944 = dz.devices(944) -- Change the name to your device
local 945 = dz.devices(945) -- Change the name to your device

if 97 > 250 then
944.switchOn().checkFirst()
dz.log('Dummy 1 On', dz.LOG_FORCE)
elseif 97 >500 then
945.switchOn().checkFirst()
dz.log('Dummy 2 On', dz.LOG_FORCE)
elseif 97 < 500 then
945.switchOff().checkFirst()
dz.log('Dummy 2 Off', dz.LOG_FORCE)
elseif 97 < 250 then
944.switchOff().checkFirst()
dz.log('Dummy 2 Off', dz.LOG_FORCE)
else
dz.log('Geen actie nodig ', dz.LOG_FORCE)
end
end
}

Just a quick try

Code: Select all

local scriptVar = '-=# TEST SCRIPT #=-'

return {

                    },
        
        logging = { level  = domoticz.LOG_ERROR,
       		        marker = scriptVar 
       		        },
       		
       		

execute = function(dz, device)
    local Stroom = dz.devices(94).WhActual  -- Change the name to your device
    local Dummy1 = dz.devices(944) -- Change the name to your device
    local Dummy2 = dz.devices(945) -- Change the name to your device
    
        dz.log('Stroom          :  ' .. Stroom ,dz.LOG_FORCE)
        dz.log('Dummy 1         :  ' .. Dummy1.state,dz.LOG_FORCE)
        dz.log('Dummy 2         :  ' .. Dummy2.state,dz.LOG_FORCE)


    if Stroom > -250 then
        Dummy1.switchOn().checkFirst()
        dz.log('Dummy 1 On', dz.LOG_FORCE)
    elseif Stroom > -500 then
        Dummy2.switchOn().checkFirst()
        dz.log('Dummy 2 On', dz.LOG_FORCE)
    elseif Stroom < -250 then
        Dummy1.switchOff().checkFirst()
        dz.log('Dummy 1 Off', dz.LOG_FORCE)
    elseif Stroom < -250 then
        Dummy1.switchOff().checkFirst()
        dz.log('Dummy 2 Off', dz.LOG_FORCE)
    else
        dz.log('Geen actie nodig ', dz.LOG_FORCE)
    end
end
}

PLEASE use CODE for the script.
Otherwise it makes the thread unreadable

I changed the log text a bit to understand and see what happens

[Wilpshaar]

I don't see the dummy2 switching on when power exceeds 1000W

That is of the "elseif" function

Change it to "if"

Code: Select all

local scriptVar = '-=# TEST SCRIPT #=-'

return {
        on      = { timer = {'every minute'},
                    },
        
        logging = { level  = domoticz.LOG_ERROR,
       		        marker = scriptVar 
       		        },
       		
       		

execute = function(dz, device)
    local Stroom = dz.devices(97).WhActual  -- Change the name to your device
    local Dummy1 = dz.devices(944) -- Change the name to your device
    local Dummy2 = dz.devices(945) -- Change the name to your device
    
        dz.log('Stroom          :  ' .. Stroom ,dz.LOG_FORCE)
        dz.log('Dummy 1         :  ' .. Dummy1.state,dz.LOG_FORCE)
        dz.log('Dummy 2         :  ' .. Dummy2.state,dz.LOG_FORCE)


    if Stroom > 250 then
        Dummy1.switchOn().checkFirst()
        dz.log('Dummy 1 On > 250W', dz.LOG_FORCE)
        end
    if Stroom > 1000 then
        Dummy2.switchOn().checkFirst()
        dz.log('Dummy 2 On > 1000W', dz.LOG_FORCE)
    end
    if Stroom < 250 then
        Dummy1.switchOff().checkFirst()
        dz.log('Dummy 1 Off < 250W', dz.LOG_FORCE)
    end
    if Stroom < 1000 then
        Dummy2.switchOff().checkFirst()
        dz.log('Dummy 2 Off < 1000W', dz.LOG_FORCE)
    end
end
}

Try to play with the script.
It is pretty easy and there are enough example or see : https://www.domoticz.com/wiki/DzVents:_ ... _scripting

HI Patrick, I think I am doing something wrong again, currently power is over minus 1200W
