Hi all,

C# developer here and kind of new to the whole scripting thing in Domoticz.
First I tried Blockly, which is nice, but I like more control.
So then I found Lua and tried some little things, which works ok.
Then I found dzVents, which I like more than Lua, so sticking with that for now.

Now I'm running into the following;
I'd like to change a dimmer level when watching a movie or watching TV, both are Logitech Harmony activities (Harmony Elite/Hub).
So I set up 4 events; both a On and Off event for both activities. The On event looks like this:

Code: Select all

return {
	active = true,
	on = {
		devices = {
			'TV kijken',
		}
	},
	execute = function(domoticz, device)
		local light = domoticz.devices('LED spots')
		if (device.state == 'On') then
		    domoticz.globalData.LEDSpotsLevel = light.level
			light.dimTo(40)
		end
	end
}

The Off event looks like this:

Code: Select all

return {
	active = true,
	on = {
		devices = {
			'TV kijken',
		}
	},
	execute = function(domoticz, device)
		local light = domoticz.devices('LED spots')
		if (device.state == 'Off') then
			light.dimTo(domoticz.globalData.LEDSpotsLevel)
		end
	end
}

The only issue with this; when I switch from "TV kijken" to "Film kijken", first the dimmer is set to the LEDSpotsLevel followed by the activity level. But these are following up eachother so fast, the 2nd instruction is ignored.

Question: How can I prevent the 2nd instruction from being ignored, or how can I prevent the 'restore' instruction from being sent at all when there's a follow-up event?

I didn't expect this would be so hard or not done before, right? Nobody knows?

The scripts you posted above do not match with your log output so It's quite hard to figure out what is happening. Also, you can easily create just one script with different on-triggers and check for them in your execute function. That keeps everything together and perhaps you can use a local spot-level instead of a global one.

The FIlm kijken events look the same:

On:

Code: Select all

return {
	active = true,
	on = {
		devices = {
			'Film kijken',
		}
	},
	execute = function(domoticz, device)
		local light = domoticz.devices('LED spots')
		if (device.state == 'On') then
		    domoticz.globalData.LEDSpotsLevel = light.level
			light.dimTo(20)
		end
	end
}

Off:

Code: Select all

return {
	active = true,
	on = {
		devices = {
			'Film kijken',
		}
	},
	execute = function(domoticz, device)
		local light = domoticz.devices('LED spots')
		if (device.state == 'Off') then
			light.dimTo(domoticz.globalData.LEDSpotsLevel)
		end
	end
}

Combining into one script might help, but I'm afraid it will be called twice; once for turning activity A off and once for turning activity B on, which gives the same problem as I'm currently experiencing.

The triggers are the same but the log shows different devices. You have two equal device triggers (Film kijken) but the log says Film kijken (Harmony) and TV kijken (Harmony). So, what are the actual scripts?

No I have 4 triggers for 2 activities; On/off for TV kijken and on/off for Film kijken.
Those 4 scripts are shown above.

What you can do is forget the off part for TV kijken and Film Kijken. Just create a new script for Power Off (a harmony state which is active when all activities are off).

So when you execute TV kijken dim level is set to 40, when you change to Film kijken it changes to dim level 20. Without first going to the original dimlevel. When you then press the off button the dim level is set back to LedSpotsLevel.

Now you need something to check if the Ledspotlevel needs to be stored since the level must only be stored when a TV kijken or Film Kijken is started.. Create a global variable named Harmony which is set to On then a activity is started and Off when all activity are stopped.

Example for Film Kijken, Added extra check if LED Spots are on. (No need to dim lights when they are off )

Code: Select all

return {
	active = true,
	on = {
		devices = {
			'Film kijken',
		}
	},
	execute = function(domoticz, device)
		local light = domoticz.devices('LED spots')
		if (device.state == 'On'   and light.state == 'On' ) then
			if (domoticz.globalData.Harmony == 'Off') then
			  domoticz.globalData.LEDSpotsLevel = light.level
			  domoticz.globalData.Harmony = 'On'
			end
			light.dimTo(20)
	
			
		end
	end
}

And for the power.

Code: Select all

return {
	active = true,
	on = {
		devices = {
			'Power Off',
		}
	},
	execute = function(domoticz, device)
		local light = domoticz.devices('LED spots')
		if (device.state == 'Off') then
			
			  domoticz.globalData.Harmony = 'Off'
		
			light.dimTo(domoticz.globalData.LEDSpotsLevel)
	
			
		end
	end
}

I can't check for Power Off only, because there are more activities, like Listen music. Switching to such an activity should also trigger the restore of the dimmer level.

This seems to work quite well:

Code: Select all

return {
    active = true,
    on = {
        devices = {
            'Film kijken',
            'TV kijken'
        }
    },
    data = {
        previousLevel = { initial = 60 }
    },
    logging = {
        level = domoticz.LOG_DEBUG,
        marker = "LED dimmer"
    },
    execute = function(domoticz, device)
        domoticz.log('Enter event for ' .. device.name .. ' | State ' .. device.state)
        local light = domoticz.devices('LED spots')
        domoticz.log('Previous level on start ' .. domoticz.data.previousLevel .. ' | Light level is ' .. light.level)
        if (light.state == 'On') then
            domoticz.log('LED on')
            if (device.state == 'On') then
                domoticz.log('Device on')
                domoticz.log('Previous level currently ' .. domoticz.data.previousLevel)
                if (light.level ~= 20) then
                    domoticz.data.previousLevel = light.level
                    domoticz.log('Previous level set to ' .. domoticz.data.previousLevel)
                end
                light.dimTo(20).afterSec(1)
                domoticz.log('Dimming to 20')
            elseif (device.state == 'Off') then
                domoticz.log('Device off')
                light.dimTo(domoticz.data.previousLevel)
                domoticz.log('Dimming to ' .. domoticz.data.previousLevel)
            end
        else
            domoticz.log('LED off, bye bye')
        end
    end
}

Especially the part light.dimTo(20).afterSec(1) fixes my issues.

Going to use some parts of your script.
