PIXIE Contact Sensor Transceiver is a smart device that monitors open & closed status of gates/doors/windows, via a set of contact sensors (sold separately).
Push Notifications to users are delivered (PIXIE PLUS App only) when status change occurs.
Any status change can be used as a trigger for logic control within the system to deliver more advanced home automation functions.
e.g. if the door is open, then turn on a PIXIE smart switch (PIXIE PLUS App only).
