The Kessil® WiFi Dongle plugs into the K-Link port of a Kessil® A360XE, A360X or A500X LED and, together with an Android / iOS Smartphone, gives the ability to effectively remotely control a wide array of features through Kessil®'s intuitive app. Same as the K-Link communication method, but wirelessly, the WiFi Dongle even networks up to 32 X lights, thereby minimizing signal interference and leading to a faster, more reliable connection. The Kessil® app provides access to advanced manual controls and program customization such as individual adjustment of individual color channels without changing the core spectrum and the ability to synchronize groups of lights. Features include full color control, customized light intensity to acclimatize new "residents", lunar cycle, weather effects and many more! A summary page on the dashboard of the app provides an overview of the status of all connected WiFi Dongles and X-lights in one glance, to group and assign them to different programs for advanced settings.
