VerhoBot

VerhoBot - Open Source Smart Curtain Robot

VerhoBot is a compact, battery-powered smart curtain robot designed to automate existing curtain rails using affordable and widely available hardware.

Built around the ESP32-C3 and an N20 geared motor, VerhoBot is designed to be easy to build, easy to modify, and fully open source. Whether you want a simple curtain timer or a fully integrated smart-home device, VerhoBot provides a flexible platform for makers, engineers, and DIY enthusiasts.

Why VerhoBot?

Many people use blackout curtains to improve sleep quality, but waking up naturally with sunlight is often just as important. VerhoBot can automatically open or close your curtains on a schedule, through a web interface, or through future smart-home integrations.

The project was inspired by Finnish summers, where bright nights and early morning sunlight can make sleep schedules challenging.

Build It. Improve It. Share It.

VerhoBot is more than a curtain robot it is an open platform for learning embedded systems, mechanical design, battery-powered electronics, and smart-home automation.

If you build one, remix it, improve it, or adapt it for your own project, please share your version with the community.

Sleep in darkness. Wake up with sunlight.
