The Aeon Labs KeyFob is a Z-Wave Remote Control, which features all the functionality of larger Z-Wave remote controls into a smaller, more modern design. Because of its small size it can be fit on a keyring and taken anywhere with you. This Key Fob Remote Control can be set up as the primary controller of a Z-Wave network or as an additional Z-Wave controller. This is perfect for including it as a remote control in an existing Z-Wave network. This device operates in two distinct modes: setup and use. Each of the four buttons on the Key Fob can control multiple Z-Wave devices with a simple push and can control up to 8 different scenes. When included securely the device is able to accept secure commands and to send secure commands to other devices. It is powered by an internal lithium cell CR2450 3V battery.
