Issue with persistent data

Posted: Tuesday 09 January 2018 1:59

Hi,

I have been struggling to get persistent data to work without success.

I am running RPI3, Raspian Stretch Lite 2017-11-29 updated and upgraded recently with domoticz V3.8799

What I am trying to accomplish is to increase a lamp to 100% if there is a motion detected and once the motion is off again, revert to the level the lamp had before, in this case 33%

The script is really simple, but I get 'nil' when I am trying to run it.
Any ideas?

Code: Select all

return {
	active = true,
	on = {
		devices = { 'Trapphus Innerdörr' },
		timer = {},
		variables = {}
	},
	data = { OldLevel = {initial=0} },
	logger = {},
	
	execute = function(domoticz, device, info)
		-- code
	    if (device.state == 'Open') then
	        OldLevel = domoticz.devices('Kök Fönsterlampa').level
	        domoticz.log('Level at ON = ' .. tostring(OldLevel), domoticz.LOG_INFO)
	        domoticz.devices('Kök Fönsterlampa').dimTo(100)
        else
	        domoticz.devices('Kök Fönsterlampa').dimTo(OldLevel)
	        domoticz.log('Level at OFF = ' .. tostring(OldLevel), domoticz.LOG_INFO)
        end
		
	end
}

Code: Select all

Not sure if this is the best solution but you can try changing "OldLevel" to "domoticz.data.OldLevel" within the if/else construct

Thank you!

I obviously had missed that detail.

But I still do not get it to work. The persistent data is still nil when I enter the else case.

Code: Select all

return {
	active = true,
	on = {
		devices = { 'Trapphus Innerdörr' },
		timer = {},
		variables = { OldLevel = {initial=0} }
	},
	data = {},
	logger = {},
	
	execute = function(domoticz, device, info)
		-- code
	    if (device.state == 'Open') then
            local Level = domoticz.devices('Kök Fönsterlampa').level
	        domoticz.data.OldLevel = Level
	        domoticz.devices('Kök Fönsterlampa').dimTo(100)
	        domoticz.log('Level at ON = ' .. tostring(Level), domoticz.LOG_INFO)
	        domoticz.log('OldLevel persistent at ON = ' .. tostring(domoticz.data.OldLevel), domoticz.LOG_INFO)
        else
            local Level = domoticz.data.OldLevel
	        domoticz.devices('Kök Fönsterlampa').dimTo(Level)
	        domoticz.log('Level at OFF = ' .. tostring(Level), domoticz.LOG_INFO)
	        domoticz.log('OldLevel persistent at OFF = ' .. tostring(domoticz.data.OldLevel), domoticz.LOG_INFO)
        end
	end
}
The respons is

But now you have emptied the data section in your code.

Try this one...

Code: Select all


return {
	active = true,
	on = {
		devices = { 'Trapphus Innerdörr' },
	     },

	data = { OldLevel = {initial=0} },

	 
	execute = function(domoticz, TriggerDevice, info)
		
	
		DimmableDevice = domoticz.devices('Kök Fönsterlampa')
		
	  if (TriggerDevice.state == 'Open') then
	        domoticz.data.OldLevel = DimmableDevice.level
	        domoticz.log('Level at ON = ' .. tostring(domoticz.data.OldLevel), domoticz.LOG_INFO)
	        DimmableDevice.dimTo(100)
        else
	        DimmableDevice.dimTo(domoticz.data.OldLevel)
	        domoticz.log('Level at OFF = ' .. tostring(domoticz.data.OldLevel), domoticz.LOG_INFO)
        end
		
		
	end
}

Thank you again, sorry for the confusion with the missing data-segment, but I tried basically everything without getting it to work, so ignore the last post.

So now it work, but I found another problem. Don't know if it is due to Domoticz or dzVents, but there seems to be some kind of rounding somewhere as the level decreases by 6-7 % until it gets fixed at an even decade.
The lamp is a IKEA Trådfri E27 WS opal 980lm with SW 1.2.217 running via Philips Hue Bridge

This is ok if I am at 86% and land at 80%, but I had a case where I started at 13% and the next step was then 0%.

Starting at 86%

Starting at 13%. The first time I close the door, the lamp is still lit, but the second time it is dark and in domoticz I can see that it is not active, i.e. not 6%

Probably not the optimal solution but sets the dim values back to multiples of 20 (20,40,60,80 or 100)

Code: Select all

return {
	active = true,
	on = {
		devices = { 'Trapphus Innerdörr' },
	     },

	data = { OldLevel = {initial=0} },

	 
	execute = function(domoticz, TriggerDevice, info)
		function SpecialRound(n)
            		return  math.min(math.max((20 * math.floor(n/20 + 0.5)),20),100) 
        	end
		
	
		DimmableDevice = domoticz.devices('Kök Fönsterlampa')
		
	  if (TriggerDevice.state == 'Open') then
	        domoticz.data.OldLevel = DimmableDevice.level
	        domoticz.log('Level at ON = ' .. tostring(domoticz.data.OldLevel), domoticz.LOG_INFO)
	        DimmableDevice.dimTo(100)
        else
        	RoundedValue = SpecialRound(domoticz.data.OldLevel)
	        DimmableDevice.dimTo(RoundedValue)
	        domoticz.log('Level at OFF = ' .. tostring(RoundedValue), domoticz.LOG_INFO)
        end
		
		
	end
