This paper develops a web service for interconnect testing on HEMS devices. In order to improve ecology and usefulness of consumer devices, the development acceleration of the HEMS devices is important. However, an implementation of communications protocol is large cost of development. Especially, interconnect testing effects them. We thus develop an emulator provided by web service for the testing. By using set of scenarios which provide behaviors of ECHONET Lite node for tests, the system has a capability to correspond to the specification change.
