WattWise: Command-Line Power Monitoring and Optimization

A robotics and machine learning engineer has created WattWise, a command-line tool that monitors power usage from a smart plug and adjusts system performance based on electricity pricing. Initially built to manage the power consumption of a high-power EPYC workstation, the monitoring component is now open-source. WattWise uses Home Assistant to display real-time power usage, historical charts, and automatically throttles CPU and GPU performance to reduce costs during peak pricing periods. The power optimization features will be released later.
