Many projects have emerged to develop new ways of harnessing energy sources – Solar, Wind, Fracking, tidal, wave, … the list can go on. Rayzig has been developed to help control resources we have already, as well as control of the new resources as they become available.

The Rayzig system uses low power wireless networking to manage and control the lighting and other energy consuming systems of buildings.

Wireless communication between Rayzig modules uses Atmel Atmega128RFA1 devices which contain a microprocessor and a 2.4GHz wireless transceiver. Atmel’s Lightweight Mesh software provides communication protocols based on the IEEE 802.15.4 specification for personal wide area networks. Network transmission uses AES128bit encryption.

The system is able to meet many needs, however, it has concentrated on meeting the needs of commercial and industrial installations.

Central management of disparate Rayzig networks is possible using the Raymon software. provides large companies the ability to manage and control power operation across multiple sites.

Rayzig has some outstanding features:

  • Raymon is a  PC-based management application, which connects to a Rayzig network via a LAN/internet gateway module.
    Raymon has a powerful, user-friendly configuration editor with a wide range of operational configuration options. The editor can effect real-time operation of remote network power control modules.
  • Each Rayzig module holds descriptive information which includes text fields: description, location, floor and room. This makes a large network modules much easier to manage than if the modules were just numbered.
  • The gateway module stores an up to date list of all network modules and their current configuration. Records in the list are automatically updated by configuration changes sent from Raymon.
  • Battery operated input modules control day-to-day system operation. A low power sleep mode gives long battery life. Low battery warning (local and central) removes the need for scheduled battery replacement.
  • Rayzig has the capability to replace the networking software of all modules via an Over The Air Update (OTAU) system. This process can be initiated remotely.
