ReHelper is an electrical appliance reporting service system that combines online live broadcasts and multi-party engineers in series. When an electrical appliance fails and needs maintenance, it provides an instant online meeting, so that relevant engineers can understand the customer's electrical needs and conditions in the online meeting. ReHelper not only effectively dispatches utilities and technicians through pre-event online meetings, but also allows customers to easily supervise maintenance personnel in different areas at a remote location through live maintenance live broadcast.
