3. Compatibility
The Refoss Smart Wi-Fi Garage Door Opener is designed for wide compatibility with most garage door openers. It supports over 200 brands and 1600 models.
3.1 Compatibility Check
Before installation, it is crucial to verify your garage door opener's compatibility. Refer to the "Product guides and documents - Compatibility guide (PDF)" available on the product page. You can also perform a simple test:
- Locate the wall button terminals on your garage door opener.
- Use pliers or a short wire to momentarily short the wall button terminals.
- If your garage door opens or closes, it is compatible. If not, please contact Refoss support for assistance.
Some garage door openers, particularly those with a yellow learn button or certain purple learn buttons (e.g., some Craftsman, LiftMaster, Chamberlain models), may require an additional accessory for compatibility. If your opener falls into this category, Refoss can ship the proper accessory to you free of charge. Provide your garage opener's brand, model, learn button color, and shipping address to support.

4. Setup and Installation
Installation of the Refoss Smart Wi-Fi Garage Door Opener involves three main steps: providing power, connecting signal wires, and setting up the door sensor.
4.1 Components Overview
- 1 x Smart Garage Door Opener (main unit)
- 1 x Signal Control Cable (connects to garage door motor)
- 1 x Door Sensor with Cable (monitors door status)
- 1 x USB Adapter (for power)
- 4 x Screws, 1 x Double-sided Adhesive Tapes (for mounting)
- 1 x Test Wire (for compatibility check)
4.2 Installation Steps
- Mount the Main Unit: Secure the Smart Garage Door Opener unit near your existing garage door opener motor using the provided screws or double-sided adhesive tapes. Ensure it's within reach of a power outlet and the motor's terminals.
- Connect Power: Plug the USB adapter into a power outlet and connect the main unit to the USB adapter using the provided USB cable.
- Connect Signal Wires: Connect the Signal Control Cable from the main unit to the wall button terminals on your garage door opener motor. These are typically the same terminals where your existing wall button is connected.
- Install Door Sensor: Mount the two parts of the door sensor on the garage door and its frame. One part (with the cable) should be fixed to the door frame, and the other (magnetic part) to the garage door itself. Ensure they are aligned and within 1 inch of each other when the door is closed. This allows the system to accurately detect if the door is open or closed.
- Cable Management: Route all cables neatly and securely using zip ties or cable clips to prevent interference with the garage door's movement.

7. Troubleshooting
If you encounter issues with your Refoss Smart Wi-Fi Garage Door Opener, try the following solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not connecting to Wi-Fi. | Incorrect Wi-Fi password, 5GHz network, weak signal. | Ensure you are connecting to a 2.4GHz Wi-Fi network. Verify password. Move the unit closer to the router or consider a Wi-Fi extender. |
| Garage door not responding to commands. | Incorrect wiring, power issue, compatibility problem. | Check all wire connections, especially the signal control cable to the motor. Ensure the unit has power. Re-verify compatibility (Section 3). |
| App shows "Obstruction" or incorrect door status. | Door sensor misalignment, incorrect opening/closing time setting. | Ensure the two sensor parts are aligned and within 1 inch when the door is closed. In the app's advanced settings, adjust the "Opening time" to match your garage door's actual closing duration (e.g., from 15s to 20s or 25s). |
| Voice commands not working. | Incorrect voice assistant setup, PIN code enabled. | Verify Refoss account is linked correctly in the Alexa/Google Home app. If a PIN code is enabled, ensure you are providing it correctly. |
