As of right now I don't believe you can change the order by device, only the fans on that specific channel. Ie. 6 fans on Commander channel 1, you can change the order for that channel. Don't think you can change the order by device, make one device light before the other manually, it is done automatically by how it is detected when iCUE initiates the devices for the first time. Ie. If you want Commander Core detected first before Lighting Node Core, it has to be plugged in and detected by iCUE first before Lighting Node Core. This is something that came up with elaborate systems like 1000
