Automate your garage in Spain: Open the door with your mobile phone (Shelly 1 Plus, Mini, Gen3, Gen4)

---

Why automate your garage door with Shelly?

Automating your garage door isn't just about convenience, but also about safety and efficiency. Here are some key benefits:

• Total Convenience : Open and close your garage door from anywhere with your smartphone. Forget about lost remote controls or waiting in the rain on stormy days.
• Enhanced Security : Receive notifications if the door is left open. You can lock it remotely, giving you peace of mind when you're away from home or on vacation.
• Energy Saving : Avoid leaving your door open unnecessarily, which can affect your home's climate or the security of your belongings.
• Easy Integration : Shelly devices are compatible with voice assistants like Google Home and Amazon Alexa, as well as other popular home automation systems in Spain.
• Easy Installation : Designed for easy installation, even if you have no prior experience in home automation.

Choose the Ideal Shelly for Your Garage

All of the devices mentioned are excellent options and function as "dry contacts." This means they activate or deactivate a circuit without supplying power, mimicking the action of the push button on your remote control or the wall-mounted keypad on your motor.

Shelly 1 Plus and Shelly Plus 1 Mini

These are devices from the "Plus" line, which offer Wi-Fi and Bluetooth connectivity (for easy pairing).

• Power Versatility : Both allow the device to be powered with 12V DC , which is the standard voltage found on the control board of many garage doors in Spain. This greatly simplifies installation, as you don't need to run a 230V cable to the Shelly. They can also be powered with 24-48V DC or 110-240V AC.
• Compact Size : The Shelly Plus 1 Mini is incredibly small, ideal for tight spaces inside your motor control box.
• Enhanced Connectivity : Featuring a more powerful processor and improved Wi-Fi connectivity for greater reliability.
• Security : They allow the connection of door sensors to their digital inputs ( I ) to verify the status of the door (open/closed) and configure automations, such as closing the door automatically if you forget.

Shelly 1 Gen3 or Gen4

The Gen3 and Gen4 generations are the latest in the traditional "Shelly 1" line.

• Basic Functionality : They offer the same "dry contact" capability to activate your garage door.
• Versatile Power : Like the Plus models, the Shelly 1 Gen3 and Gen4 can also be powered by 12V DC , 24-48V DC, or 110-240V AC, making them suitable for most modern and older garage installations.
• Connectivity : They offer Wi-Fi connectivity. Gen4 introduces Matter and Zigbee on some models (like the Shelly 1 Mini Gen4), expanding interoperability with other home automation systems you may have in your home.

Step-by-Step Installation Guide (General)

Installation may vary slightly depending on your garage door opener model and the Shelly device you choose, but the basic principles are the same. Always disconnect power to the motor before handling any wiring to avoid hazards!

1. Identify the Control Terminals : On your garage door opener's control board, look for the terminals that connect the manual opening and closing button or the radio receiver for your remote control. These are usually marked "PUSH," "INPUT," "START," or similar. You need to identify the two terminals that, when momentarily pressed, activate the door. You can confirm this by pressing the terminals with an insulated screwdriver (with the motor de-energized, of course).

2. Connect the Shelly :

   • Shelly Power : Connect the 12V DC power supply (or the corresponding power supply for your Shelly, such as 24-48V DC or 110-240V AC) to the L and N terminals (for AC) or + and Ʇ / GND (for DC) on your Shelly device. Ideally, you should use the 12V DC power supply that garage door openers typically provide.
   • Relay Output (Dry Contact) : Connect the Shelly's I (Input) and O (Output) terminals to the control terminals you identified in step 1 on your motor board. The Shelly will act as a pushbutton, momentarily closing the circuit between I and O
   • Switch (SW) Input : If you want additional manual control via a physical switch (in addition to app control), connect a momentary push button between the Shelly's SW (Switch) terminal and your Shelly's power line (e.g. L or + ).

3. Configure Shelly in the App :

   • Download the Shelly Smart Control app from the App Store or Google Play.
   • Add your new Shelly device and connect it to your Wi-Fi network by following the steps in the app.
   • Set the Shelly to Momentary or "Button" mode in the app. This is essential so that the Shelly only sends a short pulse, mimicking the action "Momentary" your remote or button.
   • Optional: Door Sensors : If you use a magnetic door sensor (such as a dry contact sensor or a Shelly Door/Window 2), connect it to the digital input I of the Shelly 1 Plus, Plus 1 Mini, 1 Gen3 or 1 Gen4 to always know if the door is open or closed.

Tips for a Perfect Setup

• Push-Button Mode : We emphasize this point: it's crucial that you set the Shelly to "Momentary" or "Pulsador" mode in the app. A mistake here could keep the relay energized and damage the motor.
• Useful Automations : Set up scenes in the Shelly app to simplify your life:
  • A single button to "Open/Close Garage".
  • Smart Notifications : Receive alerts on your mobile if the door remains open for more than X minutes.
  • Automatic Closing : Schedule the automatic closing of the door if it detects that it has been left open after a specific time or at a certain time!
• Voice Assistant Integration : Connect your Shelly to Google Home or Amazon Alexa to control your garage door with voice commands like "Ok Google, open the garage door" or "Alexa, close the garage door."
• Additional Security : Consider installing a motion sensor or IP camera in your garage for complete monitoring of your space.
