Ecowitt WH51 Soil Moisture Sensor
View all Ecowitt productsCategory: Soil SensorPrice: $17.99
The cheapest honest way to know what your soil is doing: a $17.99 waterproof wireless probe that reports moisture to a $31.99 Wi-Fi gateway (a $48.99 starter kit bundles both), with a free app and free cloud history — no subscription at any layer. One gateway handles up to 16 sensors, so instrumenting every bed and pot stays affordable. No voice-assistant integration; this is a data tool, and a very good one.
