YES! - and it’s easy.
All DIY devices, and also lots of OEM devices that do not have SimHub device profiles are added via the Arduino RGB tab in SimHub. Here you can add an unlimited number of devices, however you must take care to ensure you order them correctly to ensure they display as intended.
Following the instructions below will allow you to upload multiple profiles at once.
Step 1
Ensure you have all the profiles loaded within your SimHub LED Profile Manager list.
Step 2
In the My Hardware tab of Arduino, ensure the order of your devices matches the order of the LED profiles you wish to use (typically always ensure your DDU/Wheel is the top device).
Take note of the RGB LEDs to and from. In the example shown here 1 to 20, this means the devices below it would start at 21 onwards etc.
Step 3
Navigate back to the RGB LEDs tab.
Step 4
Press Add Effect and scroll down the list until you find ''Include Profile'' - then press add.
Step 5
In the 'Include Profile' effect, select your desired profile for your additional devide in the dropdown list.
Step 6
Ensure the start position for this 'Include Profile' effect is the same number as the first number of the start point as shown in your my Hardware page.
The example shown would ensure my DDU profile starts at position 1, and as it is a 5-10-5 profile (20 LEDs total), my 'Include Profile' effect below it for brows would now start at position 21.
Step 7
REPEAT this tutorial for every additional device you wish to add. You can add an unlimited amount of devices to your RGB LEDs using this method.
