Open Your Garage With Your Phone

Visit www.BTmate.com for more info. Thieves won't be able to access your garage since you have to first click the the "pair" button of the Bluetooth receiver (Samsung HM1100) in order to pair the receiver to your phone. The receiver is attached to your overhead garage door opener and not accessible to anyone outside your garage.

Let us build the low-cost Bluetooth receiver for you (www.BTMate.com/orders). If you buy the receiver from us it includes the GD Mate App for Android. Or DIY using parts from Radio Shack. Reliable, secure and heavily tested. Will not interfere with existing garage door remotes. Works with any Bluetooth enabled smartphone, Blackberry, iPhone, Palm, Android, etc.

Note I did this project in response to a question on Y-Combinator's application.

I am hoping Y-Combinator funds one of my companies next spring.

Thanks for your interest and for all the views.

Lou, Why do the wires have polarity if they are just acting as a switch? I noticed if I accidentally reverse them the door opens without a signal.

Would it be possible to use a small relay off this circuit to create output wires that act as a true simple switched signal?

I noticed if I turn the switch on the bluetooth receiver off then on the garage door opens without the bluetooth trigger, would this happen after a power loss?

Thanks for all your effort on this!

@Nfapps Power loss (or low batt) will NOT cause the garage to open, even when power is restored.

Every switch, switches current. And current is only possible if a voltage is present. The voltage is presented by your garage door opener and for this application it needs to be DC voltage. AC voltage also has a polarity BTW, but the polarity changes every second at twice the HZ rate.

If AC voltage is present, then you need to use a relay(btmate.com, click the Relay Mate link).

Will you be making an iphone app for this

[louprado]

@highplainsdrifter64 Sadly Apple rejected my App. Apple doesn't like hacks. I will apply for their Made for iOS program and try again.

just did this mod, piece of cake... installed axis cam, just to double check that door is shut, great stuff!!! thank you (bought your app as well)

[jaageetube]

Super! Works great! Thank you so much for this. Saved me from having to buy a new garage door opener! BTW...Radio shack doesn't sell 24 guage wire...at least my local doesn't so i used 22 guage solid wire and it works great as well. 30' each of red, black and green was only $5.99 too! Thanks again!

[everittep]

Hey, Is there any specific red/black wires I should pick up in order to do this project?

[MysticMythical]

Very good app and presentation. Can I use another model of Bluetooth besides the Samsung HM1100? I have a LG HBM-230 that I'm not using, will this one work? Also, is it able to control the light from the garage opener app? Thank you.

[Dev850]

Sorry to break the news to you guys but, Liftmaster's (chamberlain) new line of openers no longer uses an analog signal to trigger opening/closing of the door. This will work on any old models out there but by summer 2012, all openers this would work on will no longer be manufactured. And furthermore, the new line of Liftmaster openers are internet capable, which means you can download an app on your phone or website and have full control of your opener and accessories from anywhere in the world

Hey man... Is been several weeks, I use it and test it for my iPhone and it works like a Champ... Awesome. 5 stars.

@kriskjb This is a question for a nutritionist because factories/farms (same thing these days) add iron to rice during the fortification process. Rice on its own is mostly cellulose and will not attenuate the signal .. but the iron might. I say this all jokingly and your idea will likely work just fine.

FYI, I tested high humidity situations and the HM1100 has to be dripping with water before humidity is an issue.

@yuvershan No, there is nothing that can be damaged by this. If you make a mistake, it simply won't work.
