Hey guys,
since a couple of hours,my Virtuino pro running on my S10 Samsung phone fails to connect to whatever MQTT broker I try to use, regardless which projects I run.

All the projects connect to the MQTT brokers when opened by Virtuino viewer running on the same phone. The same projects can also be opened without any issue by Virtuino pro on a Windows PC.

The server icon on the top left side of the screen is yellow and if I tap on it I get the message: Server Type Unknown server

is somebody having the same issue? Any suggestion?

Thank you

I love the app! 

I am using an android tablet as an always on display.  I am using an MQTT Broker on my local network to publish data about my house, power and solar setup.  It works great for a couple of hours and then the data stops updating.  It says that it is still connected (green cloud icon) but none of the data is updating.  I disconnect and then reconnect and all is fine.

Is this a bug or could I setup a background task to automatically disconnect and reconnect every hour or so so ensure that screen displays the correct info?

Thanks again.

Hey Guys, 

I know there has already been an answer to this issue but still it doesnt work for me.
When doing it exactly as in the example: 

https://virtuino.com/forum/showthread.ph...text+value

It just doesnt display a text. Dumbers work fine but String doesnt work at all...



String text1="Hello";  //Declare some variable for the text.  On Virtuino use the pin V32
String text2="";  // V33
String text3="";  // V34

//============================================================== onCommandReceived
//==============================================================
/* This function is called every time Virtuino app sends a request to server to change a Pin value
* The 'variableType' can be a character like V, T, O  V=Virtual pin  T=Text Pin    O=PWM Pin
* The 'variableIndex' is the pin number index of Virtuino app
* The 'valueAsText' is the value that has sent from the app  */
void onReceived(char variableType, uint8_t variableIndex, String valueAsText){   
    if (variableType=='V'){
        float value = valueAsText.toFloat();        // convert the value to float. The valueAsText have to be numerical
        if (variableIndex<V_memory_count) V[variableIndex]=value;              // copy the received value to arduino V memory array
        else if (variableIndex==32) text1=valueAsText;  // V32 -> Text
        else if (variableIndex==33) text2=valueAsText;  // V33 -> Text
        // else if (variableIndex==34) text3=valueAsText; // V34 ->Text
    }
   
    }
}

//==============================================================
/* This function is called every time Virtuino app requests to read a pin value*/
String onRequested(char variableType, uint8_t variableIndex){   
    if (variableType=='V') {
    if (variableIndex<V_memory_count) return  String(V[variableIndex]);  // return the value of the arduino V memory array
    else if (variableIndex==32) return text1;  // V32 -> Text
        else if (variableIndex==33) return text2;  // V33 -> Text
        // else if (variableIndex==34) return text3; // V34 ->Text
  }
 
  return "";
}

Should the text value display now display "Hello" if i declare it to be V[32]?
Or do I need to call it somehow to declare that V[32] should display the string text1 in the text value display any other way than virtuinoRun(); ?




Thanks for the Help!

I like to have my own sound for an alarm.
In the "Alarm Settings" I choose "Sound effect" and click the folder icon in the upper right corner.
There I see "/storage/emulated/0/virtuino/sounds/" and a file list header, but no files.
I definitely stored a mp3 there, can see it with file browsers.
So, what should I do?

OS is Android 11

Is there a widget that can be used to take 2 values from thingspeak and multiply them and show the result?

Hi
I have the pro virtuino version and I'm trying to connect virtuino to thingspeak.
At this time I have connected and ESP32 which send data (6 fields) to my thingspeak channel and everything is working ok.
How can I setup virtuino to read the data from my thingspeak channel and show it ?

I tried following some videos on you tube but they seem outdated in regards to the virtuino version that I have.

Hi,
Is there a way to remember the chart data period.
For example you want to view it always in the last 1 day .  Other settings like : Display all points I like also to have as a default view.
Now  I need to set this again and again to these settings.
Br,
Edwin

Hello
Nothing happen when I click on Thingspeak chart / Value list / Export or Share .csv
on my Pc or phone 
I want Chat Gpt to analyse my value lol ! so no rush 


The "auto scale" for the chart is great but when I got some wrong value from my sensor it is "unzooming"
and it is less precise 
maybe we can have the choice between "auto scale" or scale between 2 value manually ?
   

the menu is going back when the last choice arrive with  chart data period/ Last 12 hours or else 
 Maybe it should disappear when you have valitaded your choice ?
thanks

What is the purpose of the multiplier in the Modbus variable settings?

For example, if there is a float variable with a value of 1.0, and its multipliler is set to 0.001, then:

1. the associated value display widget (with "value conversion" unchecked) will show 1.0;
   
2. open the associated value editor popup (with "value conversion" unchecked), it will also show 1.0;
   
3. change the value to 2.0 and save, the float value will be updated to 2000.0;
   
4. now both the value display and the value editor will show 2000.0, which is very confusing: the value entered when saving (2.0) does not match the value displayed (2000.0) after saving.
   

It seems that Virtuino is ignoring the Unit ID in the MBAP header of a MODBUS response?

I have 2 units in a MODBUS connection that share some of the same value addresses. However, when Virtuino is unable to read these values from one of the units (e.g. due to some network or hardware failure), it has some probability to read them from a response returned by the other unit containing the same address (but maybe even with a different function code).

If I disable or remove the faulty unit from the MODBUS connection, keeping the other one reading data properly, and then modify the server-side code to hard-code the Unit ID in the response to a different value, but Virtuino could still read the data!

This makes a MODBUS connection with multiple units very unstable. Hope this problem can be solved, thanks.
