Read full description

This version of the APP lets you control the brightness for suspensions "String Lights" designed by Michael Anastassiades, only for items purchased from January 1, 2018. All items purchased before this date can be controlled separately from the previous version. In addition to the light intensity control we have added two new features: Scenes: allows to create lighting scenarios at your own pace for both individual devices or groups of devices with different light intensity within the same environment. Mesh: is a kind of "booster" Bluetooth signal that makes it possible to control all functions of the App, from the unit closest to the control device, until those further away, in cases of multiple installations in very large environments.
