Hi Patrick, got it finally work, thanks! Now very curious if it will work tomorrow with negative values, because, If I am right that did not work in blockly. Logfile latest minutes:

Code: Select all

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

        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 > 500 then
        Dummy2.switchOn().checkFirst()
        dz.log('Dummy 2 On > 500W', dz.LOG_FORCE)
        end
    if Stroom < 250 then
        Dummy1.switchOff().checkFirst()
        dz.log('Dummy 1 Off < 250W', dz.LOG_FORCE)
        end
    if Stroom < 500 then
        Dummy2.switchOff().checkFirst()
        dz.log('Dummy 2 Off < 500W', dz.LOG_FORCE)
        end
    end

Hi all,

Now I see why it does not work, I read once from someone that negative values are not recognized, I see that now also in the log. Although current Wh is negative by production of solar panels (> 1000W) value stays '0'.

So DzVents neither Blockly will not be able to control a 2-stage boiler or loading an electric car, i.e. only power on my boiler if current power use is negative 1000W or have a 2nd step switching on something when current power is negative 2000W or more...

If someone nows a solution? Thanks for helping Patrick,

you can try a work around by making the negative into a positive value

Code: Select all

    local Stroom = dz.devices(97).WhActual * -1

Thanks Patrick, I added the '*-1' and will test this weekend (if we see the sun althoug

). Now in the log negative values are returned so that is ok. If solar power and negative use we should see positive numbers then.
