I kept it in the box without using it after purchase. A 4-light ceiling light that can be operated with the smartphone app TOLIGO, with an ON/OFF timer function. Interior lighting goes IoT! This ceiling spotlight is a popular light in our store, with a cumulative sales of 54,000 units since its release. This time, by connecting the main unit itself to the app as "TOLIGO", operation in a Wi-Fi environment has become possible. With the app, you can turn it ON/OFF with your smartphone from anywhere, anytime, so you can turn it on when you return home in the evening. You can freely turn it ON/OFF and control the lights from the dedicated app, not only at home but also while you are out or at work. - Operation: Operable with a smartphone - Design: White x Light Natural - App Name: TOLIGO - Function: ON/OFF timer function Thank you for viewing.
