Smart home from scratch - a little C#, a little C++ and cheap Chinese electronics

on YouTube ↗51m

" summary

Builds a local smart-home network with cheap AliExpress parts using ESP8266/ESP32 microcontrollers, a Raspberry Pi Zero touch controller, mains relays and 3D‑printed faceplates. Uses a peer-to-peer UDP bus so lights and switches keep working when the cloud or Wi‑Fi fail, implements over-the-air updates plus a USB debug fallback, and avoids batteries by using safe mains power supplies. Multiple hardware iterations and some failed screens occur but the installed system runs locally and is repairable.
