Show HN: Terminal dashboard that throttles my PC during peak electricity rates
A terminal-based power monitoring dashboard and power optimization controller that helps optimize energy costs by automatically throttling CPU/GPU resources during peak electricity pricing periods.
However, checking power statistics using the kasa phone app or Home Assistant dashboard proved cumbersome, especially when I already maintain a terminal window with monitoring tools like htop, nvtop, and nload in a 2×2 grid on my secondary display. The result: WattWise, a lightweight CLI tool that pulls power usage data from smart plugs (either directly or through Home Assistant) and presents it in a clean, information-dense dashboard right in the terminal. A large, easy-to-read current wattage display Color-coded elements based on consumption thresholds Real-time updates with configurable refresh intervals Historical graph using Unicode block characters for compatibility across terminals
