JavaScript Powered Smart Home With (Almost) No Code
summary
Builds a working smart-home system using Node-RED flows wired to Espruino and Raspberry Pi devices, Johnny-Five/raspi-io libraries, Docker, IFTTT and MongoDB. Temperature and humidity sensors post HTTP updates every minute; a soil sensor sends a 0–100 value and triggers an email or tweet below 25%/10%. Sunset triggers turn exterior lights on one hour after dusk and off after four hours; a relay automates the air exchanger for 20-minute intervals and on poor air readings. All flows run and log events to the database.
