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.
