For Designers seeking to produce a Smart Energy compliant In Home Display Telegesis can significantly simplify this process with our new ETRX2USB-IHD.
Telegesis is now shipping our successful ETRX2USB ZigBee USB stick pre loaded with ZigBee Smart Energy In Home Display (IHD) firmware. In addition we can also supply our USB stick loaded with Certicom test certificates for demonstration purposes or with full Certicom certificates for use in production applications.
We have also added an AT command layer on top of the ZSE IHD firmware so that your host application can easily control the ETRX2USB-IHD.
Telegesis has received full certification from the ZigBee Alliance on the ETRX2USB-IHD as an approved ZigBee Smart energy In-home display. Part of the ZigBee Smart Energy (ZSE) profile requirement is the inclusion of Certicom certificates for extra security. These can only be supplied after a product has passed certification
IHD Demo Kit.
Telegesis has released a Demo kit with all the component parts needed to evaluate this system.
The kit comprises:
•ETRX2USB stick preloaded with the ZSE IHD firmware and Certicom test certificate.
•USB stick with a basic "mock meter" firmware
•A demo application to run on a PC and it's source code
The second USB stick in the kit acting as a "mock meter" has basic but functional firmware to aid the design process. Embers application builder was used to generate firmware to act as a basic ZigBee Smart Energy meter sending random readings every few seconds.
A simple Demo application is also included in the kit as is the source code.
The IHD demo kit is available now. Please contact us for pricing and technical information
Embedding IHD firmware in other products.
Our ZigBee Smart Energy firmware can also be supplied embedded in our standard ETRX modules or even in our ZigBee CF card for use in a PDA.
However, please note that the same firmware in a module would not be classed as an end product because it will be integrated into, for example a physical display which then becomes an end product. A resulting new design would need to be re-tested and certified. However, this process is greatly simplified as the design would be use a pre-approved Telegesis ZigBee module.
Telegesis IHD AT Command Set overview
The SE IHD AT Command Set has been developed by Telegesis to provide a simple AT-style command interface to implement the In Premise Display compliant with the Zigbee Smart Energy Application Profile.
The AT-Command interface enables quick development of an In Premise Display and can shorten the time to market significantly. Developers can design and build ZigBee Smart Energy compliant products without the need for embedded firmware.
The SE IHD R1xx AT-Command line Interpreter is based on the Zigbee Smart Energy R15 specification using the ZigBee PRO feature set. Interoperability with other devices that implement the Smart Energy Application Profile and use the ZigBee PRO feature set is guaranteed.
However SE IHD R1xx is not compatible with devices that do not implement the Smart Energy Profile. Also it is not compatible with earlier versions of ZigBee.
To simplify the communication with the Telegesis modules, an AT-style command set, similar to the industry standard Hayes modem control language, is used. Each command must be preceded by the "AT" or "at" prefix.
The following table gives a quick reference of all commands available.
