The ready-to-go kit contains two power plugs with a beautiful round shape. The Crownstones can be plugged into European power outlets for 240V (in particular, type C, E, and F for Europe, Russia, and South-America). The Crownstones are plug and play and can be used directly from your iOS, Android phone or tablet.
Crownstone pursues a methodology in which we build functionality over the course of time! First we introduce new functionality under beta conditions and afterwards we roll it out to everybody. See our roadmap for what to expect when. You can find a wealth of information about this product online: detailed specifications and also code repositories. The current plug is specified for lights that use more than 5W.
