To operate: App for color / menu choice downloadable, but not really useful and also very unreliable.
Some of the lamps are not found in Wi-Fi, some of them do not respond to commands.
Mir is also not clear why the manufacturer IWY Light can not develop a product belonging to app available, but one to be content with a less than good working standard Light App must take.
This has led me to return the lamps and an attempt to start with the more expensive Philips Hue.
