Smart home gardening devices frequently tell you that your plants need a little TLC, but they don't always deliver it; you frequently have to bring out a hose or watering can. If Edyn successfully funds its smart garden system, you may not have to trudge out to the backyard quite so often. The core is a WiFi-connected sensor that detects both the soil quality and ambient conditions, cross-checking those against your choice of greenery. If the sensor decides that your plants need some hydration, Edyn's iOS app automatically tells an optional smart valve to deliver just the right amount of water-- yes, you can be waste-free and lazy. Both the sensor and valve combine solar power with lithium-ion batteries, so you don't have to worry about watering on cloudy days.
