Raspberry Pi Price Hikes Forced a Protocol Upgrade. The Smart Home Runs Better.
When a general-purpose computer becomes a single point of failure in a distributed system, the rational response is to decompose the architecture. That is exactly what happened when Raspberry Pi raised prices three times since December 2025, pushing some models 83% above launch. The 16GB Pi 5, originally $120, now costs $205. The cited cause: a global DRAM shortage. For one user, the cost spike triggered a migration from a monolithic Raspberry Pi hub to a mesh of ESP32 microcontrollers. The unexpected result: a more resilient, faster, and quieter smart home.
