Essentials Wireless window contact

(This text is machine translated) The Essentials wireless window contact reliably detects open windows or doors. If monitored windows or doors are opened without permission while the residents are away, the alarm is triggered via the alarm sirens from the Essentials product portfolio. In addition, the resident receives an alarm as a push message on their smartphone. The window contact is conveniently taught to the essentials Smart Home control center within a few minutes via the free smartphone app.
