Review on Transform Your Outdoor Space With KNONEW'S 1000 LED 403Ft Multicolor String Lights For Christmas, Weddings, And Parties! by Brandon Daughenbaugh

It has a memory of the last function setting as long as it has power to the function selector and you use the remote to turn it OFF. The default power on state is light ON with COMBINATION mode selected. So putting these on a wall switch or wifi switch results in the most annoying flashing lights result when you turn on the power. You must use the remote or the function selector to get to 8 = STEADY ON, which should have been the default, and is the default mode for some string lights from other sellers. Otherwise, it a lot of little lights for my large attic storage space. Leaving it on a powered outlet is fine if you keep the remote handy, but if the power is interrupted, you will have a flashing light show when power is restored. The neighbors will be entertained by your flashy home.
