Real switch vs. dummy-switch

[OCB73]

Hi!

I have 2 nearly identical scripts, one with a window/door-sensor and the other one with a dummy-switch.
The script with the real switch is only triggered when the window is opened or closed. The script with the
dummy-switch is triggered every 5-10 minutes. Is this normal?

If yes, can i do something, that the script is only triggered when the dummy-switch is switching?

Here my scripts, hope it helps to solve my problem.

Window/Door-Sensor, named script_variable_fkt-kzeg.lua:

Code: Select all

local Thermostat = 'Thermostat Kinderzimmer EG'
local Fensterkontakt = 'Fensterkontakt Kinderzimmer EG'

commandArray = {}
        if devicechanged[Fensterkontakt]=='On' then
                commandArray['Variable:Thermostat Kinderzimmer EG'] = otherdevices_svalues[Thermostat]
                commandArray[1]={['UpdateDevice']='28|0|15.0'}
        elseif devicechanged[Fensterkontakt]=='Off' then
                commandArray['UpdateDevice']='28|0|' .. tostring(uservariables['Thermostat Kinderzimmer EG'])
        end
return commandArray

Dummy-Switch, named script_variable_ht-wz.lua

Code: Select all

local Thermostat = 'Thermostat Wohnzimmer'

commandArray = {}
        if (devicechanged['Heizungssteuerung über Außentemperatur'] == 'On') then
                commandArray['Variable:Thermostat Wohnzimmer'] = otherdevices_svalues[Thermostat]         
                commandArray[1]={['UpdateDevice']='5|0|15'}         
        elseif (devicechanged['Heizungssteuerung über Außentemperatur'] == 'Off') then
                commandArray['UpdateDevice']='5|0|' .. tostring(uservariables['Thermostat Wohnzimmer'])         
        end
return commandArray

Why are the script file names starting with "script_variable" and not "script_device"?

Hmmm...maybe i understood something wrong...
thats the reason why:

That link is confusing for me. Maybe it is easier when you explain what it is you are trying to do and what is going wrong.
The 5-10 minutes trigger you describe is something I don't understand where that could come from. Does anything show up in the domoticz.log for that?
Either way: When you want to test for device changes you need to name your scripts script_device_xxxx.lua as described in the Events Wiki page: https://www.domoticz.com/wiki/Events

Hi!

Again thx for fast reply...

I just posted the link cause you replied in that thread.

In case the thermostat only needs updating when a uservariable changes. the file should be named like script_variable_xxx.lua

Thats the reason for the name of my scripts.

My script for the real switch is working fine! The other script not, cause it´s triggered every 5-10 minutes.

Code: Select all

2016-06-10 12:46:08.954 EventSystem: Script event triggered: script_variable_ht-wz.lua
2016-06-10 13:01:36.063 EventSystem: Script event triggered: script_device_ht-wz.lua
2016-06-10 13:11:07.139 EventSystem: Script event triggered: script_device_ht-wz.lua

I have setup a dummy switch, which is going on/off depending from the outside-temp.
If outside-temp is over 20 degrees, switch is on and user-variable is updated, heating-valve is going down to 15 degrees.
If outside-temp is under 20 degrees, switch is off and heating-valve should go back to stored user-variable.

All is working, but when the script is triggered every 5-10 minutes, user-variable is set to 15 degrees.
Thats my problem.

Ok, couple of observations/questions:
1. When you have a script triggered on a uservariable, it doesn't make sense to test for a devicechange (as that will never happen!), but rather test for the uservariable changed!
2. How is the user variable updated? Is that done through the Domoticz LUA event system or external script? A Lua script won't work as that never triggers a variable script. a JSON call will trigger it.

Am i so wrong with my script??? The first one is working fine!

Let me explain:

Thermostat = heating valve
Fensterkontakt = window/door-sensor

If the window/door-sensor goes on, the script saves the actual value of my heating-valve
to my uservariable and if the window/door-sensor goes off, the heating-valve goes to the
value stored in my uservariable. Thats exactly what i want and it´s working without a problem.
The script is only triggered when the window/door-sensor is switching.

But in the second one, there is no real switch! It´s a dummy-switch and it triggered every
5-10 minutes and not when the dummy-switch is switching from on to off or vise versa.
And exactly this is causing my problem.

No worries about wrong or right here.

The thing I still don't understand how a script file called script_variable_fkt-kzeg.lua is run by the event system when switch Fensterkontakt changes. This does not make sense to me.
Suggestion for that second script: Rename it to script_device_ht-wz.lua which should then be ran whenever any device changes including the dummy switch.

Jos

You are really fast in answering!
I don´t now why it´s running but it´s running...i did all in Lua, maybe interesting.

I renamed both script around 13 o´clock, posted above, still the same.

Ah ok... you aren't using files but the internal scripts, so the name doesn't matter but rather the selection under the LUA box. So all clear now.
So that means that device 'Heizungssteuerung über Außentemperatur' is changing or else you wouldn't see these log entries.
What does the LOG show for that device?

... and so on. But why, i don´t understand that.

So something is setting this Dummy switch to Off and seems to be a process that runs every 10 minutes.
Any CRON job running that could be setting this switch or any idea what process could setting it to Off?

Good Morning!

I found my problem. It was caused by a logic problem in Blockly, which was caused by a Domoticz-Newbie.
I am the newbie and must say sorry. But maybe other newbies do the same mistake. So here is the logic
problem and what i have done:

Blockly Event in combination with Netatmo causing my problem

Unbenannt.PNG (8.17 KiB) Viewed 3298 times

New Blockly Event, hopefully without problems

Unbenannt2.PNG (12.68 KiB) Viewed 3298 times

This blockly-event is switching my dummy-switch on or off, depending on the outside-temp.
Many thanks for the help!!!

It's always simple ones you figured it out.

Always check the status of the switch you want to switch to prevent repetitive commands

[jvdz]

Since you mentioned it: I am using the below LUA function to switch devices to ensure it only performs an actual change when the device has a different status. It just takes the devicename and a standard device command like On/Off/Set Status xx and any addon.
It will always create a Log entry so you know what happens why.
Jos

Code: Select all

function SwitchWhenDiff(DeviceName, iCommand)
	-- retrieve current device status information
	local dstatus = otherdevices[DeviceName]
	local dvalue = tonumber(otherdevices_svalues[DeviceName])
	if dvalue == nil then
		dvalue = 0
	end
	if dstatus == nil then
		dstatus = "??"
	end
	--
	local Command = ""
	local Level = 0
	local Suffix = ""
	-- check for valid starting command to perform
	if string.sub(iCommand, 1, 2) == "On" then
		Command = "On"
		Level = 255
		Suffix = string.sub(iCommand, 4)
	elseif string.sub(iCommand, 1, 3) == "Off" then
		Command = "Off"
		Level = 0
		Suffix = string.sub(iCommand, 5)
	elseif string.sub(iCommand, 1, 9) == "Set Level" then
		Command = "Set Level"
		Level = tonumber(string.sub(iCommand, 11, 13))
		Suffix = string.sub(iCommand, 11)
	else
		-- unknown command exiting
		print("!###  SwitchWhenDiff Unknown command for DeviceName:" ..DeviceName .."|   iCommand:" .. iCommand .."|")
		return
	end
	-- ensure we don't have any nil values to avoid errors
	if Level == nil then
		Level = 0
	end
	if Suffix == nil then
		Suffix = ""
	end
	-- process information
	print("!###  SwitchWhenDiff DeviceName:" ..DeviceName .."|   iCommand:" .. iCommand .."|  Command:" .. Command .."|  NewLevel:" ..tostring(Level).. "|   Currentstatus:" ..dstatus .."|  value:" .. dvalue)
	if dstatus == nil then
		-- invalid switch found
		print(" ==>  Invalid switchname " .. DeviceName .. "  (" .. ScriptName .. ")")
	elseif (dstatus == Command and dstatus == "Set Level" and dvalue >= Level - 3 and dvalue <= Level + 3) then
		-- no change so don't do anything
		print(" ==>  Nothing to change for Dimmer (within margins +/-3) " .. DeviceName .. "  (" .. ScriptName .. ")")
	elseif (dstatus == Command and dstatus ~= "Set Level") then
		-- no change so don't do anything
		print(" ==>  Nothing to change for " .. DeviceName .. "  (" .. ScriptName .. ")")
	elseif (Command == "On" and dstatus == "Set Level" and dvalue >= 0) then
		-- no change so don't do anything: request an On command for Dimmer and it is already have a status of "Set Level" and percentrage GT 0
		print(" ==>  Nothing to change for dimmer " .. DeviceName .. "  (" .. ScriptName .. ")")
	else
		--
		print(" ==> Set " .. DeviceName .. " to:" .. iCommand .. "   inx=" .. #commandArray + 1 .. "  (" .. ScriptName .. ")")
		commandArray[#commandArray + 1] = {[DeviceName] = iCommand}
	end
	return
end

Thx for the script. A little bit confusing for a beginner like me
at the moment, but later useful i think.
