grew tired of watering plants manually. built a thing. what it does: reads moisture sensors, decides when to water, logs everything real-time dashboard — per-zone humidity, pump control, tank alerts nightly backup, excel export, full history all on-premise. nothing leaves your server. ever.

ESP32 firmware is fully open source (MIT) — read it, fork it, break it, improve it. free forever for 1 cell. pro (5 cells) free during beta. no credit card. 👉 docker: github.com/jaffa2970/nestgrow-backend/releases/latest
