multiple textlines in textdevice

[Gravityz]

Hello,

i have a textdevice which i use to display the last status.

is there a way to display multiple lines so i can use it as a log.

e.g. i use this comand at the moment

domoticz.devices('Status').updateText('Woonkamer lampen ingeschakeld')
which displays Woonkamer lampen ingeschakeld

now when i issue a second command like
domoticz.devices('Status').updateText('Alarm ingeschakeld')

i want to see the most actual one on top and the other one below

Alarm ingeschakeld
Woonkamer lampen ingeschakeld


i know this can be done in lua(but i do not know how) butdoes this work in dzvents

Hi,
I'm using this:

Code: Select all

 departimestext = departimestext .. ' '..departime ..';\r\n'
 

and result for text device is next:
Status: 08:21:24
08:23:30
08:29:00

You get check in my GIT:

Thanks,
got is working(sort of)
the problem i have now i need to limit the amount of lines to max 5 i think
is there an easy way to do this


this is my code

currentstatus = domoticz.devices('Status').state ..'\r\n'
newstatus = 'Woonkamer lampen sfeervol ingeschakeld'
currentstatus = newstatus .. ';\r\n'..currentstatus ..'\r\n'
domoticz.devices('Status').updateText(currentstatus)

try this code:

Code: Select all

limit_max = 5

for m = 1, limit_max do
	currentstatus = domoticz.devices('Status').state ..'\r\n'
	newstatus = 'Woonkamer lampen sfeervol ingeschakeld'
	currentstatus = newstatus .. ';\r\n'..currentstatus ..'\r\n' 
	m = m + 1
end
domoticz.devices('Status').updateText(currentstatus)

hm. wonder if this works

this script is called everytime somebody comes/leaves or when a schedule kicks in.

m is not a global variable so i think every time the script is called m=1
in case it does remember after 5 times it will not refresh anymore

[zygios]

Try this:

Code: Select all

limit_max = 4
temp_stastus = ''
m = 1

currentstatus = domoticz.devices('Status').state

--removing 5-th status
for i in string.gmatch(currentstatus,  "[^\r\n]+") do
    print(i)
	if m <=4 then 
		temp_stastus = temp_stastus .. i.. "\r\n";
		m = m + 1
	end
end

newstatus = 'Woonkamer lampen sfeervol ingeschakeld'
currentstatus = newstatus .. ';\r\n'..temp_stastus
domoticz.devices('Status').updateText(currentstatus)

this indeed works with limiting the messages

however as far as i can see the top line is changing but the others are not.

the idea is that when things change the old messages shift down.

eg

a
b
c
d
e

new message f
f
a
b
c
d

new message h
h
f
a
b
c

i think i need to combine things from the old code and your new code but this is looking promising

If I understand your requirement correct, the function addRollingTextLine in below script should do it.

Code: Select all

return {	
			on =    {
						timer = { 'every minute' },
                      		},
        
    logging =   { level   = domoticz.LOG_DEBUG ,                  
                  marker  = "multiLine text function"},
              
    execute = function(dz, item)
		
        local function addRollingTextLine(textDevice, line, maxLines)
        
            local function stringSplit(str)
                local lines = {}
                for s in str:gmatch("[^\r\n]+") do
                    table.insert(lines, s)
                end
                return lines
            end
            
            local function checkParms()
                if not textDevice or ( type(textDevice) ~= "string" and type(textDevice) ~= "table" ) then
                    dz.log("textDevice should be of type table or string; now: " .. (tostring(textDevice) or type(textDevice)),dz.LOG_ERROR)
                    return false
                elseif type(textDevice) == "string" then 
                    textDevice = dz.devices(textDevice) 
                end    
                if not line then
                    dz.log("No text supplied",dz.LOG_ERROR)
                    return false
                end
                if not maxLines then maxLines = 5 end          -- default
                return true
            end
                
            if checkParms() then
                local lines = textDevice.text or ""
                lines = stringSplit(lines) 
                lines[0] = line
                local newText = ""
                for i = 0, ( maxLines - 1) do 
                    newText = newText ..  ( lines[i] or "" ) .. "\r\n" 
                end
                textDevice.updateText(newText)    
            else
                return false
            end
        end 
        
        -- Test call 
        addRollingTextLine("multiLine", dz.time.raw, 3)
        
    end
}

Hi waaren.

that code works very nice

Knipsel2.JPG (21.46 KiB) Viewed 1285 times

the only downfall is that i need to add it to every script that is updating the status device.

is it possible to put this into some kind of module or helper function.

eg declare it once and then call it from every script you like

Have a look here where exactly that is described in detail

[Gravityz]

Thanks waaren, you made my day.
i have read that myhelper part multiple times over and over again and could not figur out how it was working, until now.

after reading MORE CAREFULLY i noticed what i was doing wrong

working perfectly now

i now can use the Status textdevice as a logging device lights on/of alarm on/off sunscreen in/out. al the things i normally wrote to the log are now visible
