5. Compatibility Check
Before installation, it is crucial to verify that your existing garage door opener is compatible with the LoraTap Smart Garage Door Opener. This device works by simulating a button press on your existing wall button terminals.
- Locate the wall button terminals on your garage door opener. These are typically labeled and connect to the physical wall-mounted button.
- Using a pair of pliers or a short piece of wire, momentarily short-circuit these two terminals.
- If your garage door opens or closes when the terminals are short-circuited, then your opener is compatible with the LoraTap Smart Garage Door Opener.

6. Setup & Installation
The Smart Garage Door Opener is a companion device to your existing wired garage door opener. Its main working principle is to connect in parallel with your existing wall push button and monitor the door status with a wired sensor.
6.1. Wiring the Controller
- Disconnect Power: Ensure the power to your garage door opener is completely disconnected before proceeding.
- Connect AC Power: Connect the Live (L) and Neutral (N) terminals on the LoraTap controller to your AC power supply (100-250VAC).
- Connect Signal Cable: Connect the Signal Cable to terminals S1 and S2 on the LoraTap controller. Then, connect the other end of the Signal Cable to the wall button terminals on your garage door opener. This connection is in parallel with your existing wall button.
- Connect Sensor Cable: Connect the Sensor Cable to terminals S3 and S4 on the LoraTap controller.

6.2. Installing the Wired Sensor
The wired sensor consists of two parts: a sensor unit and a magnet. These need to be installed on your garage door and wall/frame to detect the door's open/closed status.
- Close Garage Door: Ensure your garage door is fully closed before installing the sensor.
- Mount Sensor and Magnet: Mount one part of the sensor (the main unit) on the wall or garage door frame, and the other part (the magnet) on the garage door itself.
- Ensure Proximity: When the garage door is closed, the sensor unit and the magnet must be less than 10mm apart for proper detection.
- Secure Installation: Use the provided double-sided adhesive tapes or screws/brackets for secure fixation of the sensor.

9. Troubleshooting & FAQ
- Q: Is the brand of my garage door opener important?
A: No, the brand of the engine is not important. This smart device connects in parallel with the existing wall push button, making it compatible with most wired garage door openers. - Q: How does the device control the garage door?
A: The device's output is an impulse dry contact signal. The relay is isolated from the internal circuit of the module. It provides a short pulse (not a constant pulse) to simulate pressing the wall button. - Q: Can it work for a sliding gate?
A: Yes, it can work for opening a sliding gate if you have a one-gang wall push button for the gate. This smart device connects in parallel with the wall push button. - Q: Do I need a separate hub?
A: No, you do not need to buy a separate hub. This device connects directly to your home's 2.4GHz Wi-Fi network. - Q: What if my Wi-Fi signal is weak in the garage?
A: A strong Wi-Fi signal is essential for this device. Try connecting your phone to Wi-Fi next to the garage door opener. If your phone works, the device should too. If not, consider using a Wi-Fi signal repeater to extend coverage. - Q: Is it compatible with RF remotes (433Mhz or 868Mhz)?
A: No, this is a Wi-Fi-only device and does not work with any RF 433Mhz or RF 868Mhz remotes. - Q: Is it compatible with Apple HomeKit?
A: This device is not directly compatible with HomeKit. However, you can often add 'Tap-to-Run' scenes from the Smart Life app to Siri Shortcuts for some integration.
10. User Tips
- Wi-Fi Signal Strength: Before final installation, ensure your garage has a strong 2.4GHz Wi-Fi signal. A weak signal can lead to unreliable operation.
- Sensor Placement: Experiment with sensor placement to find the most secure and reliable position that maintains the less than 10mm gap when the door is closed.
- Voice Command Customization: Customize the names of your garage door in the Alexa or Google Home app to make voice commands more natural and easier to remember.
