It’s the ability of the Crownstones to know where you are if you carry a smart device with you. Crownstones use the position of this smart device through measuring Bluetooth Low Energy signals. This makes it possible for the Crownstones to react upon your presence and proximity.
Expect a Crownstone to broadcast 5-10m to contribute to the indoor positioning
Try to have most places covered by around 4 Crownstones. Most often 2 Crownstones per room gives enough info to the classifier.
The classifier is a room-based and uses fingerprints. An accuracy “in meters” does not reflect this.
More Crownstones means fewer misclassifications which means algorithms can make their decisions faster.
You sit on the couch and it is getting dark
The lights in the room where you are can be turned on automatically. Presence information is needed to avoid lights going on even if you are not there!
Go to bed without worries
Forget about manually turning off stuff before going to bed. Lights and devices can be automatically turned off when you are not present in a room and after a certain time.
Because always it's better safe than sorry
Turning off outlets when an adult is not around gives peace of mind! Specially knowing that no one can play with it in a dangerous manner.
