Terminal dashboard that throttles my PC during peak electricity rates
WattWise is a CLI tool that monitors my workstation’s power draw using a smart plug and automatically throttles the CPU & GPUs during expensive Time-of-Use electricity periods. Built with Python, uses PID controllers for smooth transitions between power states. Works with TP-Link Kasa plugs and Home Assistant.
In plain words
WattWise is a command-line tool that reduces electricity costs by automatically throttling CPU and GPU performance during peak-rate Time-of-Use periods. It monitors power consumption via smart plugs, integrating with TP-Link Kasa devices and Home Assistant, and uses PID controllers to smoothly adjust performance states. Built in Python, it targets users who want to minimize energy expenses on their workstations without manual intervention.

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
