How to Make a Garage Door Opener with a Belkin WeMo Maker Part 1

How to Make a Garage Door Opener with a Belkin WeMo Maker Part 1 Using a WeMo Maker to build your own smart garage door is fairly easy. In this blog post I’ll explain how to set it all up.

There are three things you will need to put this together:

The Magnetic Sensor and Speaker Wire are optional. If you want to know when the garage door is open or closed, then you will need them. If you just want to be able to open or close your garage door, then the WeMo Maker will suffice. I recommend putting in the sensor, though, because you can do some pretty neat stuff if you have it.

As a side note, if you have multiple garage doors, you will need a WeMo Maker for each door that you want to control unless you are handy at building electrical circuits. I’m not going to get into that at all, though.

Setting Things Up

You’ll want to start by getting the WeMo Maker set up by following the instructions that come with the device so that you can control it. After you have the device set up so you can manage it within your WeMo App you can start connecting it to your garage door.

WeMo Maker

First, we’ll look at the Relay connections. The Relay connection has a place for two wires. These two wires will need to connect to your garage door opener to the same location that your garage door button is connected to. The garage door button has two wires as well. We are turning the WeMo Maker into a second “garage door button.” Each garage door is a little different; you will just have to climb up and take a look at your opener to see where the wires will need to go.

In the pictures, you can see how I connected everything. You’ll notice that I connected the sensor wires to the S and Minus connections, which will be important when setting up the magnetic sensor in the next section.

Magnetic Sensor

If you want to be able to tell if your garage door is opened or closed, we’ll need to look at the Sensor connections. The Sensor connection has places for three wires. These wires will connect to the Magnetic Sensor.

As you can see, I only used two wires. One wire goes to the COM connection, and the other goes to the NC connection (Normally Closed). The sensors pieces need to be relatively close together to activate. The sensor comes with adhesive pads, so it is easy to stick it anywhere you need to. I have one part of the sensor on the door, and the other part on the guide rail. You will notice a tiny arrow on the part of the sensor that does not have the screw connections, that arrow needs to be pointing towards the screw connection sensor for it to work properly. That is why you can see that mine looks like it is mounted sideways. This sensor was made to be screwed into something, like the top edge of a door for example.

WeMo App

Now that everything is set up we should be able to see the Maker in the WeMo app and also see the sensor status of the Maker. The sensor status will say either Sensor triggered or Sensor not triggered.

You should be able to open and close your garage door at this point. If you set it up just like I did then when it says Sensor triggered, that means the garage door is open. When it says Sensor not triggered, that means the garage door is closed.


I think this is an easy way to give your home a smart garage door. WeMo already integrates with a lot of services like IFTTT, Stringify, and Workflow, which can be used to do some cool stuff. In my next blog post, I will walk you through setting up some notifications and rules for truly making the garage door smart. Stay tuned for Part 2.
