Why does this dzVents script not work [Solved]

[RvdM]

Hi all,

After migrating to the newest version of Domoticz my climatControl scripts (written in dzVents) stopped working.
Based on the temperature and humidity in our home certain user variables are regularly set.
Based on several time scripts the mechanical fan should switch to a lower or higher RPM (DIMMER 0-10V Z-WAVE)

Tried to get this working again but somehow I can't. Even the log line doesn't work.

Code: Select all

return {
        active = true,
        on = {
                ['timer'] = {'at 19:28'}
        },
    
    	logging = {
            level = domoticz.LOG_DEBUG,
        },

        execute = function(dz)
            
            fan = dz.devices('Mechanische Ventilatie')
            target = domoticz.variables('climatControlBaselinePostCooking').value
            
            domoticz.log('Mechanische ventilatie snelheid wordt aangepast (Post-Cooking) - Level: ' .. target )
            fan.switchSelector(target)

        end
}

I don't know dzVents, but it can help

Code: Select all

return {
        active = true,
        on = {
                ['timer'] = {'at 19:28'}
        },
    
    	logging = {
            level = domoticz.LOG_DEBUG,
        },

        execute = function(dz)
            
            fan = dz.devices('Mechanische Ventilatie')
            target = dz.variables('climatControlBaselinePostCooking').value
            
            dz.log('Mechanische ventilatie snelheid wordt aangepast (Post-Cooking) - Level: ' .. target )
            fan.switchSelector(target)

        end

You cannot mix dz (first parm of the execute function) and domoticz in the body of the script. Either they are both dz or both domoticz.

What are the possible values of the variable climatControlBaselinePostCooking ?

Ah yes. With that the printing works. However still not the adjustment of the fan.
User variable is a integer.

Code: Select all

return {
        active = true,
        on = {
                ['timer'] = {'at 21:14'}
        },
    
    	logging = {
            level = domoticz.LOG_DEBUG,
        },

        execute = function(dz)
            
            fan = dz.devices('Mechanische Ventilatie')
            target = dz.variables('climatControlBaselinePostCooking').value
            
            dz.log('Mechanische ventilatie snelheid wordt aangepast (Post-Cooking) - Level: ' .. target )
            fan.switchSelector(target)

        end
}

User variable is a integer.
But for the selector
must be 0ff, 10, 20 ..... 60

[RvdM]

Shouldnt that be fine with an integer?

[besix]

Code example for selector

Code: Select all

if (dz.devices('Kominek').state == 'On' and dz.variables('kominek').value == 0) then
		    dz.devices('Kominek Wentylator').switchOn()
			dz.devices('Kominek przepustnica').switchSelector(60)
			dz.log('Rozpalanie')

The position of the selector 60 is the name of the level.
Level 1 is Off, 2 is 10, 3 is 20 etc.

Yes, it should. Can you show whats in the log ?

The position of the selector 60 is the name of the level.

Sorry but no.

60 is the level in this example. The name can be any string.

I assume based on this that the device is not set at level 50 ?

Can you show a printscreen of the levels of the device?
What is the type / subtype (as seen on the device tab?

[RvdM]

See attached, and no its not set to 50

selector please no dimmer
or

Code: Select all

return {
        active = true,
        on = {
                ['timer'] = {'at 19:28'}
        },
    
    	logging = {
            level = domoticz.LOG_DEBUG,
        },

        execute = function(dz)
            
            fan = dz.devices('Mechanische Ventilatie')
            target = dz.variables('climatControlBaselinePostCooking').value
            
            dz.log('Mechanische ventilatie snelheid wordt aangepast (Post-Cooking) - Level: ' .. target )
            fan.dimTo(target)

        end

switchSelector is to be used for selector type devices. For dimmers you should use the dimTo() method

[RvdM]

That indeed was the probleem. No sure why it worked in older versions of Domoticz because this script was from a post 2020 release

[RvdM]

Just started up the old machine and the code looks like this

Code: Select all

return {
        active = true,
        on = {
                ['timer'] = {'at 18:30'}
        },
        execute = function(domoticz)
                domoticz.log('Ventilatie op post-kookstand')
                domoticz.devices('Mechanische Ventilatie').switchSelector(domoticz.variables('climatControlBaselinePostCooking').value)
        end
}

Could well be that this switchSelector() method worked in your old version. It was never intended to work on a dimmer device and since the change in the switchSelector code in dzVents 2.4.22 it no longer work for dimmers.
