How I've been using JavaScript to automate my house
summary
Projects reuse JavaScript on microcontrollers to control lights, doors and toys using Espruino, ESP32 and ESP8266 boards, Raspberry Pi and Node-RED flows. Working builds: a beer-can voice/face notifier (camera recognition sends welcome messages), a PS3-joystick remote car prototype, web-triggered door relay and room sensors feeding Node-RED dashboards. Surprises: face detection runs near real time on tiny boards but memory caps (4 MB flash, ~80 KB RAM) force tradeoffs; radar sensors false-trigger lights; Espruino has limited async/library support and remote SSH flashing eases OTA.
