Wireless control that simply works

A core part of the AlertMe system is its use of ZigBee technology in the home. ZigBee is a wireless system that allows devices to communicate over short distances. It is straightforward enough to work on small, simple devices such as light switches, but can carry enough data to monitor and control a security system, to track energy usage around the home, and much more.

It uses a similar radio frequency to both Bluetooth and WiFi (2.4GHz), but is rather less well known! Unlike Bluetooth, ZigBee can communicate between many devices at once, and over greater distances (a single ZigBee network will connect together all parts of an average UK home). ZigBee doesn't need as much power, or computer processing ability, as a WiFi network.

AlertMe is a Participant member of the ZigBee Alliance, which is a global ecosystem of companies creating wireless solutions for use in residential, commercial and industrial applications. The ZigBee Alliance companies work together to enable reliable, cost-effective, low-power, wirelessly networked products based on an open global standard.

AlertMe will be increasingly visible at ZigBee Alliance events (and in conference calls) over the next few months as Amyas and I start to participate in the development of the standard. If you are one of the many people involved in the ZigBee world, do say hello to us!
