The eWindow handle ConnectSense reliably detects break-in attempts at the window and reports them to the smart home hub. Additionally, it recognizes and reports the position of the handle (closed, tilted, open) as well as the position of the window sash (closed, open). By continuously comparing the positions of the handle and window sash, it accurately determines whether a window is actually open or if the handle is simply in the open position without the window sash being moved. The eWindow handle ConnectSense offers extensive features for monitoring window states in the building – potentially even while on the go via a smartphone notification.
