Intelligent garden irrigation for your plants & beds
Two weeks of vacation and nobody to water? Or forgotten yet again whether the bed already got its water?
Tending a garden by gut feeling costs time, water and sometimes the plant. GardenTwin brings zones, irrigation and care tasks together at a glance — controlled automatically, but always overridable by you.
In development, not available yet
GardenTwin waters based on soil moisture and the weather forecast and pauses when it rains — so only what the plants really need is watered. If you connect a rain barrel or cistern, rainwater is used first; fresh water only steps in when the supply is empty. And a plant that gets enough water at the right time has to be replaced less often.
GardenTwin
GardenTwin is a complete system: our own, self-developed hardware in the garden plus an app and the GardenTwin Hub that control everything. It is not an app you attach to an existing irrigation setup — the technology in the garden is part of GardenTwin. Three parts work together: the app, the valve boxes in the garden and the GardenTwin Hub.
On your phone you see which plant needs water when, and you can water manually at any time. It can be installed on your phone like a regular app.
Our valve boxes do not just contain the valves themselves, they also measure soil moisture right at the plant. They connect via Wi-Fi.
The Hub is a small computer that is connected to your home Wi-Fi/LAN. It collects the measurements, takes the weather forecast into account and plans the irrigation. It runs at your place, and the control does not need a third-party cloud. Only for weather data and plant recognition are external services queried. A subscription is not planned for it.
GardenTwin worksStep 1 of 4: Measure
The valve box measures soil moisture right at the plant.
Irrigation and plant care are usually kept apart: one app controls the watering, another handles care schedules and plant knowledge. GardenTwin brings both together in one system. And it is meant to belong to you: buy it once, no subscription, no ads. Because it runs at your home, the control stays in your hands.
There is an integration for Home Assistant that lets you connect GardenTwin to an existing smart home. The integration is built; the real-world test in an actual garden is still pending.
GardenTwin is still in development and not available yet. The app, the Hub and the software of the valve boxes are being built right now. What will be available later, when and on what terms has not been decided yet.
GardenTwin can doThe key features at a glance.
Your plants are watered when they need it — and not when it rains.
Zones in the garden are watered automatically based on soil moisture, plant needs and the weather forecast. Rain is detected, and planned irrigation is then paused or reduced automatically. You decide freely what a zone is — from a single bed to the whole lawn.
