User experience to enable long-term operation for HEMS

In recent years, there are many studies on Home Energy Management System, HEMS for short. HEMS reduces electric power consumption by a visualization function and a remote control function. However, an action for a trouble of apparatuses and a setting of a system are complicated in using HEMS. If a user has no clue for solving, it is necessary to ask the maker or seller. Thus we focus on the trouble shoot problems for HEMS apparatuses. This study develops user experience to support long-term operation for HEMS.
