For the indoor gardener who wants to stop overwatering, the RAINPOINT Smart Soil Moisture Meter gives you real-time soil insights without guesswork. Press the button for a quick manual read, or let it auto-check every 3 minutes. With the RAINPOINT Home app, you can view moisture levels from anywhere, so you'll know exactly when your fern needs a drink.
Pair with the optional Wi-Fi hub (HWG023/HWG040) to build an automatic watering system. Connect a compatible timer, and your plants get watered only when the soil is dry. No more soggy roots or wilted leaves. The advanced sensor reads moisture with ±5% accuracy, picking up what your eyes can't see below the surface. It's IP54 rated for outdoor use, so you can monitor your garden through rain and shine. If the moisture dips below your set threshold, the app sends an alert. You'll know your tomatoes are thirsty before they start drooping.
