## Description

Intelligent soil sensor connects to smart app, precisely measuring moisture, light, and temperature for fully automated garden watering without a smart gateway.

Review: Good, but let down by software - Sensor seems to accurately detect soil moisture level, but i had hoped the Gardena app could "average" values from multiple sensors in different parts of the garden (some with more light etc than others) The current version of the Gardena watering smart app only permits a single sensor per watering zone
Review: Saves water and has long battery life - Stops unnecessary watering when used with the Gardena Smart watering system. Batteries last nearly a year and the integration with the app is very good. As expected, a great product from Gardena.

*by B***K on 5 October 2025*

Sensor does exactly what it needs to do but it is very expensive. Tied into the Gardena system so no other option unless I go down the more complex home hub automations.
