The continuous evolvement of the smart grid might startle the consumer with different choices for Home Energy Management Systems (HEMSs). The assessment analyses of different HEMSs don't provide a solution or an incentive for further research, because the unified quality evaluation system does not exist. In this paper we propose a reference model design for an user-centric Quality Control System (QCS) for smart HEMS. The system quality attribute is appraised by the Quality of Service (QoS) and Quality of Experience (QoE). The proposed QCS is evaluated on a real-time test bed of a set of different types of power appliances. The results showed the improvements of 10% of energy savings, 18% reduction in the electricity bill, while the consumer quality of life was not affected. The stability of our QCS, the balance between the QoS and QoE, provides a user engaged model for a sustainable quality control for responsible, environmental and cost-efficient HEMS.
