dimming a group [Solved]

[snellejellep]

Hi all,
i tried making a script which allows a dimmer switch control and dim a group.
simple on/off worked but i tried reading this script and use some things to let the group dim: https://www.domoticz.com/forum/viewtopi ... 28&t=23568
but unfortunately i get this error and i have no clue:

Code: Select all

2019-11-27 16:51:02.266 Error: dzVents: Error: (2.5.0) An error occurred when calling event handler knop group tk
2019-11-27 16:51:02.266 Error: dzVents: Error: (2.5.0) ...ticz/scripts/dzVents/generated_scripts/knop group tk.lua:14: attempt to index a nil value (field 'data')

this is the script:

Code: Select all

return {
	on = {
		devices = {
			'Tuinkamer licht'
		}
	},
	execute = function(dz, device)
		dz.log('Device ' .. device.name .. ' was changed', dz.LOG_INFO)
		
		local switch        = dz.devices("Tuinkamer licht")
		local group         = dz.groups("Tuinkamer licht")
		
		if switch.state == "On" and switch.level > 0 then
		    dz.data.dimLevel =  switch.level
		    group.switchOn()
		    group.dimTo(tonumber(dz.data.dimLevel))
		elseif switch.state == "Off" then
		    group.switchOff()
		end
		
	end
}

i hope someone can help me

As far as i know a group cannot be dimmed, lamps can be dimmed.
What you can do is read one switch (define that as somekind of a group master in your thoughts)

Then with a script like above change the dimming value based on that master switch value for every individual lamp
Maybe that way it will work.
Not sure how it works in dzevents

in lua it would be something like
a=otherdevices["lamp1"]
commandArray["lamp2"]=a
commandArray["lamp3"]=a
commandArray["lamp4"]=a

this way the value of lamp1 will be copied to the others

you can with a script, i tried before and it seems to work.
unfortunately i do not know lua, all my scripts are in dzvents

"you can with a script, i tried before and it seems to work."

Maybe you can use same approach in DZ ? dimm all lamps upon value change ?

yes but i need to extract the current value of the switch and use that value to dim the group to that value
the only thing is i do not know how to do that... setting a static dimmed value i do know but this i don't ant that is exactly my question, how do i do that in dzvents

    },
    
    execute = function(dz, item)
        _G.logMarker =  _G.moduleLabel
    
        local myGroup = dz.groups('Tuinkamer licht') -- Confusing ! Can you rename device or group ?
        
        if item.state ~= 'Off' and item.level > 0 then
            myGroup.devices().forEach(function(dv)
                dz.log(dv.name ..' ==>> device-level: ' .. dv.level,dz.LOG_FORCE)
                dv.dimTo(item.level)
           end)
        elseif item.state == 'Off' then
            dz.log(item.name ..'; state: ' .. item.state,dz.LOG_FORCE)
            myGroup.switchOff()
        end
    end
}

great! that is exactly what i was looking for!

[dheuts]

Thanks a lot for this script, great.
I'm looking for some script like this, to control the color temperature (Kelvin) of a group (RGBWW).
Can someone please help me with this? I think we have to do something in the script with:
getColor
SetKelvin

But I'm not sure how to get this running. Is it possible with the same device as the brightness slider? Or do we need another one?

UPDATE: Got it running with this script:
