Door/Window Sensor - Fibaro Door/Window Sensor 2

Door/Window Sensor 2 - A brand new Door/Window sensor from Fibaro. Door/Window Sensor 2 has a built-in temperature sensor, but no longer allows for the connection of an external temperature sensor or external closed contact. Fibaro's door/window sensor is a battery-powered Z-Wave sensor that can be used to detect if a door or window is open/closed. The product consists of two parts. One part is mounted on the movable part of the window or door. The other part is placed on the frame. Replacement battery ER14250 can be purchased here.
