I have 2 stripsc1 5 m 1 2.5 meter . The lights all work wled is great. My question is i sometimes want the 2 strips to work as one and other times i would like them to be different. Is segments the best way?
Yes, in general you will use segments to define the portions of the whole setup you wish to address.
You can apply effects, grouping and interleaving as you need to either. Once you have the “look” you want, save it as a preset. You can then change things completely and/or create one segment with the whole strip included and again save the settings in a different preset.
That should give you full control over how you manage your LEDs.
Ty for your time.
