This Compact Sensor Brings Real Intelligence to Plant Care

Smart homes have mastered lighting, heating and security, yet plant care has long relied on guesswork. Plant With Willow looks to change that with a compact, intelligent sensor that translates real time soil and environmental data into clear guidance for healthier houseplants.

Designed for modern living spaces, Willow blends discreet hardware with a companion app, removing the uncertainty from watering schedules and light placement. Instead of relying on routines, users receive alerts based on what their plants actually need.

How it works

A slim sensor sits quietly in the soil, monitoring the conditions that matter most to plant health. This includes moisture levels, light intensity, temperature, humidity and nutrients.

Data is collected every few minutes and analysed in the Willow app, which then notifies users when to water, move or feed their plants. The system responds to real conditions rather than generic reminders, helping prevent both overwatering and neglect.

Built for smarter care

After watering, the app confirms whether moisture levels are where they should be, offering reassurance or guidance if adjustments are needed. Over time, Willow analyses soil trends to spot nutrient issues or absorption problems before visible damage appears.

Light is measured every minute, making it easier to position plants correctly, while temperature and humidity tracking ensures sudden environmental changes are not missed. Each plant is also given a simple happiness score, offering an at a glance snapshot of overall health that works just as well for beginners as it does for experienced plant owners.

Designed to scale

The Willow Starter Pack includes one Sensor and one Hub. The Hub connects everything to the app and supports up to 40 Sensors, making the system suitable for anything from a single houseplant to a full indoor collection.

The Plant With Willow Starter Pack is priced at £34.99 and is available now from plantwithwillow.co.uk.
