README
README.mdGarage ESPHome Controller
Overview
This project provides a comprehensive solution for automating and monitoring a garage door using the ESP32-C3 Super Mini microcontroller. The controller integrates seamlessly with Home Assistant via ESPHome, enabling smart home automation and remote control.
Key Features
- ESPHome integration for easy Home Assistant setup and monitoring
- Current sensor for accurate detection of fully open/closed garage door states by monitoring motor current
- External push button support for manual operation
- 12V remote receiver compatibility (e.g., INEL ORS-X1T) for remote control
- Compact hardware design fits standard enclosure with receiver
- Complete KiCAD hardware design files and ready-to-use ESPHome YAML configuration

Electric circuit diagram
Assembly & Integration
- Use the provided KiCAD or Gerber files to manufacture the PCB. I recommend using JLCPCB service, which offers high quality PCB boards for only $2.
- Assemble the PCB using the schematic above.
- Install all components in the enclosure, connect 230V power and your garage doors to the terminals. Optionally, you may connect external button or radio remote receiver.
- Adjust the RV potentiometer such that there is 0V on R7.
- Flash the ESP32-C3 Super Mini with the included ESPHome configuration.
- Add the device to Home Assistant via ESPHome for full smart home integration.
Additional Recommendations
- Use the ESP32-C3 Super Mini version with an external antenna socket and connect a suitable WiFi antenna.
- Ensure all wiring and installation comply with local electrical safety standards.

Questions
How big is the Garage PCB?
It measures 90 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Garage use?
32 parts, built around the HLK-30M12C, LM358 and LM2940T-5.0/NOPB. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Garage KiCad files?
From the macdems/Garage repository on GitHub, at the commit this page was made from: the board is garage.kicad_pcb and its schematic acs712-sim.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Garage design in my own project?
Its repository states no licence, so its author keeps all rights: ask macdems before reusing the design.
