YoMoPie - A User-Oriented Energy Monitor based on the Raspberry Pi

1 minute read


Computational methods for the enhancement of energy efficiency rely on a measurement process with sufficient accuracy and number of measurements. Networked energy meters, energy monitors, serve as a vital link between the energy consumption of households and key insights that reveal strategies to achieve significant energy savings. With YoMoPie, we propose a user-oriented energy monitor for the Raspberry Pi platform that aims to enable intelligent energy services in households. YoMoPie measures active as well as apparent power, stores data locally, and integrates a user-friendly Python library. Furthermore, the presented energy monitor allows users to run self-designed services in their home to enhance energy efficiency. Potential services are (but not limited to) residential demand response, immediate user feedback, smart meter data analytics, or energy disaggregation.
