WattWise: CLI Power Monitoring and Management for High-Performance Workstations

Facing high electricity bills from a power-hungry workstation built for LLM workloads, the author developed WattWise, a lightweight CLI tool for real-time power monitoring and management. WattWise displays real-time power draw, historical charts, and dynamically adjusts CPU/GPU frequencies during peak electricity pricing periods. It integrates with TP-Link Kasa smart plugs (directly or via Home Assistant), offering flexibility and practicality. While currently limited to single plug support and Kasa compatibility, its modular design allows for future expansion.
