About the Project

OpenShrooly is an experimental open-source replacement firmware for the Shrooly mushroom growing device, originally funded through Kickstarter.

It appears (as of September 2025) that the Shrooly company has gone out of business and many user have reported that their apps no longer work.

This firmware transforms your Shrooly into a Wi-Fi-only device that can be controlled via a local web interface or integrated with Home Assistant.

• Open Source - Full transparency and community-driven development
• Home Assistant Integration - Seamless smart home ecosystem integration with temperature control
• Intuitive Touch Controls - Drag-and-drop sliders for humidity, temperature, and lighting schedules
• Customizable Settings - Fine-tune cultivation parameters for different mushroom varieties

Important Warning

⚠️ This is an experimental project - many users have installed it successfully, but use at your own risk!
