Visual component with id (im2) already exists

Sato

Hi kl3m3n,

I have 4 small graphs on https://i.imgur.com/XXxxXX.png, that alternate depending on the signal strength in the modem. I want to update it in periods of every 60 seconds.
The problem is that after 60 seconds, the next time I load the same graphic, the error message appears in the Gui-O,
Visual component with id (im8) already exists,
because it has already been loaded once. Is there any way to solve it?

Best regards

Sato

Hi kl3m3n,

Perhaps one way to solve this would be if it were possible to assign a variable to IM UID:var

Best regards

@sato you are probably creating another |IM component with UID:im8 (which already exists). Try updating the IP parameter of im8 to change the image:

@im8 IP:"<image>"\r\n

BR,

Hi @kl3m3n

Thanks for the Tip, but it not update the graphic.
What make i wrong?

loop()

   unsigned long currentTime = millis();
  if (currentTime - previousTime >= eventInterval) {   // every 20 seconds
      previousTime = currentTime;    
      s_quality = modem.getSignalQuality();
     
     if (oneTime == 0) {   // it load the graphic

mqttClient.publish(&In[0], "|IM UID:im8 X:10 Y:45 W:12 H:12 OPA:1 SCI:0 SCM:2 VIS:1 IP:"https://i.imgur.com/GGxxxxx.png"\r\n");
oneTime = 1; // load the graphic only one time and it works
}

    if (s_quality >= 24) {
     mqttClient.publish(&In[0], "@im8 VIS:1 SCI:0 IP:\"https://i.imgur.com/8dxxxxx.png\"\r\n");  // but don't update! The graphic exists
     Serial.println("Signal Top +");                                                       
    }
    else if ((s_quality >=20) && (s_quality <= 23)) {

mqttClient.publish(&In[0], "@im8 VIS:1 SCI:0 IP:"https://i.imgur.com/2dxx3xx.png"\r\n"); // but don't update! The graphic exists
Serial.println("Signal Good");
}
else if ((s_quality >=16) && (s_quality <= 19)) {
mqttClient.publish(&In[0], "@im8 VIS:1 SCI:0 IP:"https://i.imgur.com/TJxxxxx.png"\r\n"); // but don't update! The graphic exists
Serial.println("poor signal");
}
}

Best regards

Hi Kl3m3n,

This works, only the IP without the SCI and VIS

mqttClient.publish(&In[0], "@im8 IP:"https://i.imgur.com/vFexxxx.png"\r\n");

Solved
Thanks
