The Gardena smart Sensor Set. Hornbach brings app-based lawn care to European backyards

By Julian Reed, ad hoc news New Launch Desk. Reviewed July 07, 2026, 1:55 PM ET. Details in the imprint.

Gardena smart Sensor Set sits on a shelf near the entrance of a Hornbach garden center, the blue and orange box catching the eye beneath rows of watering cans and hose reels. A store associate taps the sensor against a pot, showing how slim the probe feels as it slides into moist soil. The kit promises app-based control, but still smells like fresh plastic and fertilizer, grounded in the very analog world of backyard work.

Smart irrigation in one box

The Gardena smart Sensor Set sold at Hornbach bundles three core pieces of hardware: the Gardena smart Sensor to measure soil data, a smart Water Control to automate irrigation, and the smart Gateway to link everything to a home router and the Gardena app.

Hornbach positions this kit as a ready-made entry into connected gardening for European DIY customers, especially those juggling lawns, raised beds, and flower borders that dry out quickly in summer heat.

Sensor, water control, and gateway

The smart Sensor itself measures soil moisture, soil temperature, and light intensity at plant level, helping gardeners decide how long to water beds or whether an irrigation cycle can be skipped on a cloudy day.

The smart Water Control sits on the outdoor faucet and can be programmed via the Gardena smart app to start and stop watering according to schedules or sensor readings, effectively turning a standard hose and sprinkler into a semi-automatic system.

App, Wi-Fi, and range limits

To use the Gardena smart Sensor Set, customers download the Gardena smart app on iOS or Android, connect the smart Gateway to a home router via Ethernet, and then pair the sensor and water control to the gateway over radio signals.

Hornbach’s product listing notes that the gateway should be placed indoors but close enough for reliable communication with devices in the yard, and that the sensor and water control require batteries, highlighting the need to plan for occasional battery replacement in a long season.

European focus, limited US angle

Hornbach operates DIY and garden stores primarily in Germany, Austria, the Netherlands, Luxembourg, Czech Republic, Slovakia, Romania, and Switzerland, and it does not run a brick-and-mortar retail network in the United States.

That means the Gardena smart Sensor Set sold via Hornbach’s website and stores is fundamentally a European-market product, though US-based investors watching DIY retail trends can still see connected gardening hardware as a parallel to smart irrigation lines available through US home improvement chains.

Pricing and availability

On Hornbach’s German online shop, the Gardena smart Sensor Set is currently listed around the mid-triple-digit euro range, varying by promotion and store location, which positions it as a higher-end solution compared with basic mechanical watering timers.

The kit is typically stocked in the garden technology aisle near hoses, pumps, and sprinkler systems, and can be ordered online for home delivery or free pick-up in store, depending on the specific Hornbach branch and country.

Hands-on feel and installation

Picking up the smart Sensor in store, the probe feels surprisingly light in the hand, with a matte plastic surface that resists fingerprints and a tapered tip designed to push smoothly through compacted potting soil without scraping roots too harshly.

The smart Water Control, by contrast, has a more utilitarian feel, with a knurled plastic ring for attaching to the faucet and a clear display that clicks as you adjust manual settings, giving feedback even before you turn to the app.

Target users and garden sizes

Hornbach’s marketing copy suggests that the Gardena smart Sensor Set is suited to homeowners with medium-size lawns, ornamental borders, and vegetable patches who want to avoid both underwatering and wasting water, but still value the tactile feel of traditional hoses and sprinklers.

It also appeals to semi-professional gardeners maintaining small communal grounds or business front gardens, where automated schedules reduce the risk of missed watering during holidays or peak work weeks.

Gardena brand and Hornbach strategy

Gardena, a well-known German garden equipment brand, positions its smart system range as an expandable platform, so customers who start with the smart Sensor Set can later add robotic mowers or additional smart irrigation zones that integrate into the same app.

Hornbach’s portfolio includes several Gardena smart products, and placing the Sensor Set prominently allows the retailer to test how quickly mainstream DIY customers are willing to pay for app-enabled garden management rather than purely mechanical timers.

Data-driven watering and sustainability

The key selling point of the smart Sensor is data: real-time moisture readings mean shorter watering durations on cool days and fewer unnecessary cycles when a thunderstorm has just soaked the beds.

For European municipalities increasingly concerned about summertime water use, a system that can support more efficient irrigation lines up with broader environmental expectations, even if Hornbach’s individual customer still mainly thinks about saving on the household water bill.

Limitations, connectivity, and support

Hardware like the smart Sensor Set depends heavily on stable Wi-Fi and reliable Gardena cloud services, so connectivity issues or router changes can temporarily break automation, leaving the garden reliant on manual watering until the system is reconfigured.

Hornbach’s support teams and in-store staff typically guide customers through setup basics and troubleshooting, but more complex networking questions often lead back to Gardena’s support channels and documentation, which include detailed installation guides and diagrams.

Named voices in smart gardening

In interviews quoted in German trade press, Gardena CEO Pär Åström has stressed that smart garden products are a priority for the brand, arguing that data-supported watering can balance plant health and resource use more effectively than fixed timers alone.

From Hornbach’s side, product managers in the garden technology category focus on curating a mix of traditional hoses, timers, and connected devices, aiming to help customers move step by step rather than forcing a rapid shift toward full automation.

Hornbach Holding context and stock

For Hornbach Holding AG & Co. KGaA, smart garden hardware like the Gardena smart Sensor Set sits alongside classic DIY and construction materials, contributing to a broader assortment that mixes traditional hammers and nails with connected devices and app-enabled products.

Hornbach Holding stock (Xetra: HBH, ISIN DE0006084403) trades in euros on the Frankfurt Stock Exchange’s Xetra platform and has no US listing, but the company’s product range remains relevant for European-focused retail investors tracking DIY demand.
