Plugfest Overview

Plugfest is a place for interoperability tests with products brought by the member companies aiming the improvement of interoperability of products implementing ECHONET Lite.


The ECHONET Lite Specification has been recommended as a known standard media protocol for HEMS in Japan, and is showing signs of spreading. As the HEMS environment is shared by different manufacturers’ controllers and devices, it is important to have multi-vendor interoperability and compatibility. However, problems such as differences in interpretation of the Specification or errors in implementation are difficult to discover without connecting other companies’ devices.


By planning “Plugfest” events, ECHONET CONSORTIUM supports member companies in developing products with confidence. The Plugfest provides a low-pressure opportunity for member companies to connect their respective devices, confirm interoperability, and share information on implementation.

Comments from the Previous Participants

*“We were able to confirm interoperability with various ECHONET Lite devices, as well as noticing some problems we had overlooked during in-house tests.” *“We are satisfied, as we had a chance to carry out ample connection tests with actual devices.” *“Points where we had not properly understood the ECHONET Lite Specification were clarified, and we were able to discover defects.” *“We were glad of the chance to discuss ECHONET Lite with other participants.” *“By competing against other devices, we enhanced our knowledge and awareness on both the ECHONET Lite Specification and on our own products.”
