Measurements and history
Follow changes in substrate moisture, light and temperature, depending on the sensors available.
Track your plants locally
Understand your plants.
Day by day.
Gruterra is a local application for tracking plants, sensors, watering and observations. Measurements and history help you understand how your plants change over time.

Gruterra runs primarily on your computer. Your personal data, private settings and secrets stay there. This website introduces the project; it does not receive your local database.
Watering and observations
Keep a record of watering and changes you observe, and compare them with your plant measurements.
Simple analysis
Explore history and charts to better understand growing conditions and responses after watering.
Discover Gruterra without sensors
Demo mode lets you explore the application on your computer with fictional plants, measurements and watering events. No sensor, Raspberry Pi or Netatmo account is needed.
Download the archive, extract it into a folder, then follow the guide to install Gruterra and start the demo.
Demo guideInstallation guideAvailable version: 0.1.8-dev, released on 8 November 2026. Gruterra is under active development and installation is still being improved. The demo runs in the application on your computer.
Release notes and downloadsWhat you can explore in the development preview
Navigate between plants, manage a sensor inventory, follow watering sessions and observations, and explore light and measurement history. When configured, Netatmo environmental data can provide additional context; availability depends on your equipment and connection.
Photos and local diagnostic exports help document observations and troubleshoot issues. Gruterra provides descriptive information, not an automatic watering decision.
Windows features have been tested locally, but the new installer has not yet been tested on a clean virtual machine. Raspberry Pi installation and full restoration are being validated; Zigbee needs further testing and ESP32 remains experimental. The 0.1.8-dev preview is not offered through automatic updates.
A future shared database, your choice
A future contribution feature could help improve Gruterra analysis using selected plant measurements and growing events.
Sharing will be voluntary. You will be able to review the proposed data and remove information before sending it. Contributions will exclude secrets, private settings, full backups and precise addresses. Privacy rules are still being defined before public sharing can open.
This feature is in preparation. No contribution form or data submission is enabled on this page.
