These are very cool lights! but we weren’t able to find any way to use them without allowing them access to our wifi, which we were trying to avoid, there are too many internet-of-things things on our internet at this point. We got some others which have their own private wifi, and another that is controlled via a remote. Also got those from meh!
@lizzius Probably, but once the string gets too long, you’ll start to drop power, which would be easy enough to handle by injecting power at the far end of the string. But, since the controller is built-in to the power connector, I’m unsure how the lights would respond to commands while essentially getting instructions from both ends.
