Robonuts Smart Irrigation Controller

What is Robonuts Smart Irrigation Controller?

I built this before a 1-week vacation because my biggest worry was watering my backyard plants in summer. It uses ESP32, MQTT, backend, and an Android app to turn watering on/off, see live status, and manage schedules. I shared it on Reddit and it got a good number of upvotes, so I’m launching it here to get feedback and see if others find it useful too or what they think of this as a product.
