But....
It is not getting an update when you change a song.

It is possible to check the info every 10~20 sec when the script is activated to check for an update ?

Hello
I'm trying to achieve exactly the same thing : display only the Now Playing title in my Dashticz Dashboard.
I tried to follow your steps but I always get errors in domoticz logs.
Can you clarify what kind of script I mut use in domoticz ? Lua, DZVent, which type ?
And if you could eventually give me a quick step by step how to, that would be very much apreciated.
Thank you very much

Please share the errors you see in the log.
The script-type is dzVents (as per the subforum where it is posted)

__________________________________________________________________________________________________________________________
When not yet familiar with dzVents please start with reading Get started Before implementing (~ 5 minutes). Special attention please for "In Domoticz go to Setup > Settings > Other and in the section EventSystem make sure the checkbox 'dzVents enabled' is checked. Also make sure that in the Security section in the settings you allow 127.0.0.1 to not need a password. dzVents uses that port to send certain commands to Domoticz. Finally make sure you have set your current location in Setup > Settings > System > Location, otherwise there is no way to determine nighttime/daytime state."

Hello and thank you for your help

Can you add below lines directly after the line "if item.isHTTPResponse and item.isJSON then"

Code: Select all

			dz.utils.dumpTable(item.json)
			dz.log(songDisplay.text,dz.LOG_DEBUG)

For your info I finally got these errors in domoticz logs

Code: Select all

2021-04-15 14:22:52.508 Error: Error opening url: http://127.0.0.1:8080/json.htm?type=devices&rid=131
2021-04-15 14:22:52.567 Error: dzVents: Error: (3.0.2) songDisplay: HTTP/1.1 response: 401 ==>> Unauthorized
2021-04-15 14:22:52.578 Error: dzVents: Error: (3.0.2) songDisplay: Problem with HTTPResponse..
So I changed

Code: Select all

url = dz.settings['Domoticz url'] .. '/json.htm?type=devices&rid=131',
like this

Code: Select all

url = dz.settings'http://192.168.0.161:8080/json.htm?type=devices&rid=131',
Got no error anymore but nothing happens anyway

Now I modified the code like you suggested so it looks like this

Code: Select all

local scriptVar = 'songDisplay'

return
{
    on =
    {
        devices =
        {
            131, -- ID of your LMS device
        },

        httpResponses =
        {
            scriptVar,
        }
    },

    logging =
    {
        level = domoticz.LOG_DEBUG, -- set to domoticz.LOG_ERROR when all OK
        marker = scriptVar,
    },

    execute = function(dz, item)
        songDisplay = dz.devices('SONG') -- change to name of your virtual text sensor

        local function getSong(delay)
            dz.openURL(
            {
                url = dz.settings'http://192.168.0.161:8080/json.htm?type=devices&rid=131',
                callback = scriptVar,
            }).afterSec(delay)
        end   
        
        if item.isHTTPResponse and item.isJSON then 
            dz.utils.dumpTable(item.json)
			dz.log(songDisplay.text,dz.LOG_DEBUG)
            newText = 'Now playing: ' .. item.json.result[1].Data
            if songDisplay.text ~=  newText then
                songDisplay.updateText(newText)
                dz.log(newText, dz.LOG_DEBUG)
            elseif songDisplay.lastUpdate.secondsAgo > 600 then   
                 dz.log('No new song in the last 10 minutes. Stopping now', dz.LOG_DEBUG)
                return
            end    
            getSong(15) -- Check again after 15 seconds
        elseif item.isDevice or item.isTimer then
            getSong(0)
        else
            dz.log('Problem with HTTPResponse..', dz.LOG_ERROR)
            dz.log(item.data, dz.LOG_DEBUG)
        end
    end
}
And now I have these errors in the logs when I launch the script

Code: Select all

2021-04-15 15:17:12.365 Error: dzVents: Error: (3.0.2) songDisplay: An error occurred when calling event handler Script #2

nothing else after that even when switching to a new song

Hello
Sorry about my mistake. I did read the get started manual and allowed the 127.0.0.* but I made a mistake and used a "," instead of a ";" to separate IPs in that setup section. Sorry again.

Your code is still giving an error because of a "then" missing after

Code: Select all

        elseif item.isDevice or item.isTimer
I corrected it and it's now working perfectly.
Here is the final code

Code: Select all

local scriptVar = 'songDisplay'

return
{
    on =
    {
        devices =
        {
            131, -- ID of your LMS device
        },

        httpResponses =
        {
            scriptVar,
        }
    },

    logging =
    {
        level = domoticz.LOG_DEBUG, -- set to domoticz.LOG_ERROR when all OK
        marker = scriptVar,
    },

    execute = function(dz, item)
        songDisplay = dz.devices('SONG') -- change to name of your virtual text sensor

        local function getSong(delay)
            dz.openURL(
            {
                url = dz.settings['Domoticz url'] .. '/json.htm?type=devices&rid=131',
                callback = scriptVar,
            }).afterSec(delay)
