Bluetooth garage door opener

Today I made a Bluetooth garage door opener. Now I can open my garage from my Android phone. There’s a short how-to YouTube video from Lou Prado. Lou also made a website btmate.com that has more information, and you can watch an earlier howto video as well.

The project itself was pretty simple:
- Acquire a Samsung HM1100 bluetooth headset (the Samsung HM1800 also works). You can buy these cheap from Fry’s or eBay. I got mine on eBay for $10-$15.
- Crack open the earpiece on the Bluetooth headset and solder one of the earpiece wires to the base pin of a transistor. Solder red and black wires to the other pins of the transistor.
- Connect the red and black wires to the garage door opener. It turns out that most garage door openers are built to allow easy insertion of wires, which is nice.

That’s more or less it. My soldering was ugly as sin–too ugly for me to even post a picture. And rather than leave the house for some heat shrink tubing, I just left bare wires on the transistor, but everything works fine.

Lou wrote a nice Android app that’s free to install and then pay-what-you-want for a license. Then it’s just a single button to open or close the garage door. In theory, I could use Tasker to open the garage door automatically when I get home.

It’s not quite as sexy as Brad Fitzpatrick’s Android garage door opener, but it was a fun little project for a day.

  1. Good one Matt, over here in Oz if you’re caught with your phone in your hand while driving it’s a $450 fine and 4 demerit points so people are a bit cautious.

    Cheers,

    • Ouch! For me, it’s more about being able to open my garage door after biking home without needing to stuff an extra garage door opener in my backpack. And it makes it less likely to be locked out by accident. :)

  2. Ahhh ok that’s a great idea.

    Sometimes while out the front of the house say mowing or something like that it would be handy to be able to open the garage without running inside to get the remote.

    You may want to access the garage for any number of reasons, so it’s a great idea and makes a lot of sense.

    But I use Apple so don’t know about that…..my 2 year contract is up in a couple of weeks, time for a change ?

    Just out of curiosity,… How easy is it for someone else to open your garage door?

    I assume that the app is secure enough, but how secure is the receiver earpiece?

  4. Please Kindly Excuse me for posting regarding search

    But There is something serious kind of spam going on.

    Thankyou

  5. 2014 challenge for Matt Cutts: Learn how to solder like a pro! ;)

  6. Same here in Scotland if you even touch your phone whilst driving, it’s a £100 fine and a 3 points points on your license.

    Happy New Year.

  7. Want to get your solder on come to DefCon :) You can solder all weekend. *wink

  8. This is a great idea! Not only is it good after a bike ride but when I’m mowing the yard or working on the lawn and I need a tool out of the garage, this would be a convenient way to open the door. (Plus its just damn cool!)
