  Hello, here are some optimization suggestions:

  Modification suggestion 1:

  Replace the delay function with the FreeRTOS time function.

  void loop() {
  lv_timer_handler(); // Handle LVGL tasks
  vTaskDelay(5 / portTICK_PERIOD_MS); // Non-blocking delay
  sendDataToAll(); // Send data to all devices
  
  // Process the slider value and update the label
  updateSliders();
  }
  

  Modification suggestion 2:

  Reduce the frequency of reading the DHT22 sensor to avoid reading it in every loop.

  unsigned long lastDHTReadTime = 0;
  const unsigned long dhtInterval = 2000; // Read every 2 seconds
  
  void loop() {
  lv_timer_handler(); // Handle LVGL tasks
  vTaskDelay(5 / portTICK_PERIOD_MS); // Non-blocking delay
  
  // Read DHT22 sensor every 2 seconds
  if (millis() - lastDHTReadTime > dhtInterval) {
  temp = dht.readTemperature();
  humid = dht.readHumidity();
  lastDHTReadTime = millis();
  }
  
  sendDataToAll();
  updateSliders();
  }
  

  Hope these can help you.
