The ESP32 is replacing Raspberry Pis in my home lab for simple jobs, and it costs far less to run
I'm fully aboard the SBC train, and I'm not hopping off.
The Raspberry Pi, launched by the Raspberry Pi Foundation in 2012, aimed to make computing and programming more accessible through an affordable single-board computer (SBC). Millions of Raspberry Pi computers have been sold worldwide, making it a popular choice for smart home and home lab applications. Despite its limitations compared to a desktop PC, the Raspberry Pi excels at handling low-power tasks without requiring expensive hardware or significant electricity consumption.
However, microcontrollers like the ESP32 are increasingly being used for similar tasks due to their lower cost and energy efficiency. The Raspberry Pi 5 features a quad-core ARM CPU and up to 16GB of RAM, capable of running full-size Linux distributions, and handling various lightweight services. On the other hand, the ESP32, a microcontroller, uses significantly less power and can be powered by small batteries, making it ideal for battery-powered projects.
ESP32 development boards are also considerably cheaper than Raspberry Pi boards, leaving more room in the budget for additional components like sensors and displays. ESP32 boards can be easily integrated with Home Assistant using ESPHome, a configuration tool that allows users to set up compatible microcontrollers using YAML. The ESP32's simplicity and efficiency make it an attractive choice for projects that require minimal processing power, storage, and occasional communication with Home Assistant.
However, ESP32 is not a miniature Linux computer and lacks the processing power, memory, and software environment necessary to replace a Raspberry Pi running conventional self-hosted applications. For tasks that require USB peripherals, local data processing, graphical interfaces, or the ability to run existing Linux applications, a Raspberry Pi is still preferred.
Nonetheless, the author has increasingly turned to ESP32 development boards for their home lab, leaving the heavy lifting to Home Assistant and existing infrastructure, while deploying inexpensive and efficient microcontrollers for simpler tasks.
