Haozee HZ-SL04 Smart Soil Moisture Sensor: Real-time soil moisture and temperature detection
Forget the guesswork of watering your indoor plants or garden. This Haozee Smart Zigbee Soil Moisture Sensor is designed for plant lovers who want to move beyond finger-testing to precise, data-driven care. It connects to your smart home system via a Zigbee hub, like Tuya or Zigbee2mqtt with Home Assistant, to monitor soil moisture and temperature in real time.
You get alerts when your plants need water, not just surface-level checks. The sensor reads deep into the soil, so you know exactly when to water—no more overwatering or underwatering. Pair it with a smart watering timer for automated care, and watch your plants thrive with less effort.
