The elumia app is a wi-fi remote that lets you monitor energy consumption and set grow-lamp temperature, light cycle, etc. It has a "library" of exhisting presets (plants) with detailed information on how to grow/water/fertilize... them, but also enables you to set your own.
All important information is directly visible on your home screen - set elements from here - select desired setting - circle swipe to desider value.
Swipe down features a timeline indicating the light cycle of a specific plant. Swipe left/right enables you to operate more than one grow light.
