| Unit ID of MODBUS response is ignored? |

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.

I need to make a mini terminal for the last 6-8 strings (FIFO) i tried to do it on multilines value display but i can't send correct strings with \n
Code: String L1 = "1 line";
String L2 = "2 line";
String str = String(L1 + '\n' + L2);
sendValue(pin3, str);
Serial.print(str);
Serial.print shows strings in two lines but multiline display shows nothing

probably I didn't read it - it is possible to add to the custom image, image as animated gif . Works and looks great !
Idea: maybe you could create a library of images for widgets available to all VIRTUINO users for saving and downloading?

| Modbus TCP/IP stops working after receiving an exception response |
|

When working with a Modbus TCP/IP connection, once an exception response is received from the Modbus server, the Virtuino IoT client will stop working and not send any more requests!
For example, after I enter a value and send a Write Single Register (function code 0x06) request to the Modbus server, if the server returns any exception response (function code 0x86), then the Virtuino IoT client will stop working and will not send any more requests.
Virtuino 6 will work fine in this case. Is it possible to have Virtuino IoT continue to send requests normally after receiving an exception response?

Hi! If I buy the Pro version, is it for one device only? i need to pay for every device?

| Slow app since 0.1.0 |

My app is very slow since ver 0.1.0
I had no troubles at all with previous versions (0.0.19 and below). I updated regularly my versions since 0.0.12
But now, when I change screens (linked with a button), the app wait few seconds before displaying the new screen. And I work with the very same W10 computer since (i5/12gb ram). Even when I click the 3 menu buttons, the delay can be as high as 10 seconds, just to display the main menu.
When I create a new project (with one screen, one button), the speed is ok.
Any clue ?
I can send you my present project through email if you want to look at it.
