Hi there all,

I am making a LUA-script to switch groups.
Now a group cAn have 3 states, on/off/mixed
how can I determine what stae the group is in in LUA?
I tried otherdevices_svalues but this gives an error, this is a table variable
Any help?
Thnx in advance

Jan

From the Event Wiki page: https://www.domoticz.com/wiki/Events
To switch a scene or group, put prefix 'Scene:' or 'Group:' in front of the scene name. Note that it is not possible to check the state of a scene or group, since that is not its intended use. Check a (significant) single device from the scene/group table before switching scenes.

Is there any plan to develop the ability to know the state of a group?

Try this and let me know how it works

Code: Select all

function libs.GroupState(sArray)
        -- v1.0. 2016-01-18
        -- Checks the state of a group of swithces.
        -- USAGE   : GroupState({'Switch1','Switch2','Switch3','Switch4','Switch5',more switches})
        -- RETURNS : 'On'       if all switches are on.
        --         : 'Off'      if all switches are off.
        --         : 'Mixed"    if one or more, but not all switches are on.
        --
        local iState = 0
        local iCount = 0
        local sState = ''
        for i,light in pairs(sArray) do
                if (otherdevices[light] == 'On') then
                        iState = iState + 1
                end
        iCount = iCount + 1
        end
        if(iState == 0) then sState = "Off" end
        if(iState > 0) then sState = 'Mixed' end
        if(iState == iCount) then sState = 'On' end
--      print("iCount   : " .. iCount)
--      print("iState   : " .. iState)
--      print("sState   : " .. sState)
        return sState
end

It changes state only when I open the floorplan. Is there a way to changes every x seconds?

I don't get you?
It just checks the state of a group of devices.

I use it as below:

Code: Select all

if (devicechanged['Rörelse'] == 'On' and libs.GroupState(aLivingroom) == 'Off') then
If the "Group" of switches is "Off" (all switches is of) the do something.
If the return value is "On" or "Mixed" nothing will happen.

In the log I've got this error every minute:

Code: Select all

Error: EventSystem: in Update groups state: [string "function libs.GroupState(sArray)..."]:1: attempt to index global 'libs' (a nil value)

Hmm. Remove the libs.

Make it look like this :
function GroupState(sArray)

I have my functions scripts in a singel libs file.

Now I get
Error: EventSystem: Lua script Update groups did not return a commandArray
But when does it run? Who tells it when to run?

What I was saying previously is that in the floorplan the state of the group is updated only when i refresh the page (the single switches updates instantly).

what type of script is it?
lua with crontab?
lua with time?
Or ??

It is not a script its a function:

Below is a part of my script script_device_motion.lua

The function checks if a group if switches is on, off or mixed.

Code: Select all

GroupState(sArray)
        -- v1.0. 2016-01-18
        -- Checks the state of a group of swithces.
        -- USAGE   : GroupState({'Switch1','Switch2','Switch3','Switch4','Switch5',more switches})
        -- RETURNS : 'On'       if all switches are on.
        --         : 'Off'      if all switches are off.
        --         : 'Mixed"    if one or more, but not all switches are on.
        --
        local iState = 0
        local iCount = 0
        local sState = ''
        for i,light in pairs(sArray) do
                if (otherdevices[light] == 'On') then
                        iState = iState + 1
                end
        iCount = iCount + 1
        end
        if(iState == 0) then sState = "Off" end
        if(iState > 0) then sState = 'Mixed' end
        if(iState == iCount) then sState = 'On' end

--      print("iState   : " .. iState)
--      print("sState   : " .. sState)
        return sState
end



aLivingroom = {'Hörnbord','Soffbord','Blomma','Fönster','Bokhylla'}

if (devicechanged['Rörelse'] == 'On') then
        time = os.date("*t")
        if (GroupState(aLivingroom) == 'Off') then
                if (libs.SunSet() < 30 and time.hour <= 22) then
                        commandArray['Group:Alla Vardagsrum']='On'
                end
        end
    difference = libs.TimeDifference('Rörelse')
    myTime = libs.SecondsToClock(tostring(difference))
    tSunset = libs.SecondsToClock(tostring(libs.SunSet()))

    commandArray[3] = {['UpdateDevice'] = '43' .. '|0|' .. tostring(libs.UpdateCounter('Movement Vardagsrum1'))}
end

Hi Gert,

Thanks for the script function. Unfortunately I get some errors using it.
The log error is:

Please see the complete script below:

I did something similar in dzVents. Hope this will help. Please note that checkFirst() is available in dzVents 2.3.0 onwards which is part of domoticz Beta

Code: Select all

-- CheckFirst() available in dzVents 2.3.0

return { 
--		active = false,
    
on = { devices = { "WoonkamerPIR"  } },
        		
execute = function( domoticz,motionDetector )
	local timeSwitchState = domoticz.devices("schema2").state
	local myGroup = domoticz.groups("Woonkamer")

	if motionDetector.state == "On" and timeSwitchState == "On" then 
		myGroup.switchOn().checkFirst()
	end
end
}

Thanks a lot for taking the time to help me! I need to update to beta but I can't do this (running Pi2b) because get errors when I want to update.
I am going to fix the update first, then try the script and let you know! :)

So it took me some time to fix the upgrade. Now i am running dzvents 2.4.1 (this should support checkfirst).
The script is not working, I see no errors in the log but nothings happens when the motionsensor is activated (and the scheme is on)?

Should I choose a dzvents device script as type? Because i tried with dzvents device and dzvents group?

Jesse

<Edit> I don't use the internal script editor so I did not understood your question after first reading.
Script is a Device type and make sure you set the event to active before saving.
<end Edit>

I tested the script (with different names for sensor and group ) in 2.4.0 and it did what I expected.
If you have the Log Level for dzVents (setup, settings, other) set to "Errors + minimal execution level" you should see if the script is executed when the sensor is activated.
To see how the script run you could add some print commands and check the log when you activate the sensor. Like below

Code: Select all

return { 
    
on = { devices = { "WoonkamerPIR"  } },   -- case sensitive must be the exact name of you sensor
        		
execute = function( domoticz,motionDetector )
	
	print ("function started")
	local timeSwitchState = domoticz.devices("schema2").state
	local myGroup = domoticz.groups("Woonkamer")

	if motionDetector.state == "On" and timeSwitchState == "On" then 
		print ("schema2 and WoonkamerPIR both On"
		myGroup.switchOn().checkFirst()
	else
		print ("schema2 and / or WoonkamerPIR Off"
	end
end
}

I tried it for a few days.
When the sensor detects motion, i see the following in the log:
2018-02-04 20:37:00.799 EventSystem: Script event triggered: slaapkamerjm_uit
2018-02-04 20:37:00.802 EventSystem: Script event triggered: woonkamer_uit
2018-02-04 20:37:39.593 dzVents: Info: ------ Start internal script: slaapkamerjm_aan: Device: "PIRslaapkamerJM (zwave_aeon)", Index: 68
2018-02-04 20:37:39.598 dzVents: Info: ------ Finished slaapkamerjm_aan

But the light does not switch on.
Can it be that the script I use to turn the lights off causes an error or something?

Code: Select all

-- script_time_nomotion.lua

local motion_switch = 'PIRslaapkamerJM'
local nomotion_uservar = 'slaapkamerjm'
local status_switch = 'Slaapkamer JM lamp'

commandArray = {}

no_motion_minutes = tonumber(uservariables[nomotion_uservar])

if (otherdevices[motion_switch] == 'Off') then
	no_motion_minutes = no_motion_minutes + 1
	--print('<font color="red">No motion has been detected for: ' ..no_motion_minutes.. ' minutes</font>')
else 
	no_motion_minutes = 0	
end 

commandArray['Variable:' .. nomotion_uservar] = tostring(no_motion_minutes)

if no_motion_minutes > 15 then --change the 30 to the amount of minutes you prefer
 	commandArray[status_switch]='Off'
end

return commandArray
