Echelon Power Line Based "e -GA®" Home Network System from KyungDong Network

Brings Home Automation to the Korean Mass Market

(SAN JOSE, CA - June 30, 2005) - Echelon Corporation (NASDAQ: ELON), a pioneer in control networking and the world's leading supplier of technology for the LonWorks® control networking platform, and KyungDong Network, a Korean home automation company, today announced the availability of the e -GA home networking solution. Consisting of boiler, lighting, security, access, and gas valve control, each product will contain a Power Line Smart Transceiver from Echelon that enables the use of existing electrical lines in a home to transfer data. The e -GA solution meets the core needs for the home automation market in Korea, estimated by KyungDong at over $139,000,000 USD per year. KyungDong introduced the product line at the 2005 Smart Home and Home Network Show in Seoul earlier this month.

"KyungDong has an extensive history of successful power line based control networking in our commercial building business using Echelon's technology," said Mr. Tae Sik Min, KyungDong Network's CEO and president. "When we began evaluating the home automation market our primary concerns were reliability, performance and ease of installation. After completing a market survey, we determined that Echelon's power line technology satisfies all of the requirements for this very strategic market."

The e -GA home networking solution is ideal for both new and retrofit homes and is aimed at the mass market - for the first time putting advanced home automation within reach of the average consumer in Korea. Until now, the Korean home automation market had been limited to only premium housing. KyungDong Network has broken through the price barrier with an affordable system that will be sold by a 300+ member nationwide sales channel, thereby establishing itself as the Korean market leader for home automation.

Echelon's Power Line Smart Transceivers offer a robust, proven means of transferring data over existing power lines in the home. This low -cost and reliable technology is designed to drastically reduce installation time and cost, making it ideal for mass market home automation solutions.

"We are very pleased to see the home automation market take such a great step forward in Korea with the introduction of the e -GA system," said Bea Yormark, Echelon's COO and president. "KyungDong is a very progressive company that is seizing a huge market opportunity. We believe that Korea offers a glimpse of the future of the home automation market, which is not surprising since Korea is one of the most "wired" countries in the world, with almost 70% of the population using the Internet. KyungDong is the latest example of how great companies, seeking to establish a significant market position, are adopting our power line technology as a viable 'no new wires' home automation solution available today."

About the e -GA Home Automation System
The new system focuses on two key market needs in Korea - convenience and safety. Home owners can activate and deactivate security systems and control digital door locks from their living room. Additionally, each member of a family can set his or her own room profile, providing a "one touch" scenario for various "mode" controls in the main room (typical of Korean apartments). Lighting switches in the e -GA system can control a maximum of four lights, and the system includes auxiliary room controllers that can control up to two light switches per individual room.

Gas valve control is a critical safety feature of the e -GA system. Nearly every apartment in Korea has a gas supply line that has traditionally been a source of concern for home owners. The e -GA system includes remote control of the gas valve, and gas leak detection with alert functionality via phone or SMS (Short Message Service).

Home owners access the system via a remote control unit and a television. The system also provides remote notification for emergencies to alert home owners in cases of emergencies or failures. Any failure of devices will be automatically reported to KyungDong's service center, resulting in a service call being initiated before the consumer even realizes that there is a problem.
