Garage Door voice activated with Google Assistan on car stereo!

Projects Programming
1

Hi Everyone, im working on a project to open the garage door of my building, but i cant touch the system on the door, so im trying to clone my remote with arduino but the problem is that the remote has an HT12e chip with a dipswitch, so, i cant read it with the RC-Switch library.

Does someone know how to connect an HT12D to decode and then how to conect HT12E?
Does anyone have an sketch?

For the voice activated part i use IFTTT, Adafruit MQTT and Google assistant on my car stereo

thank to everyone that can help me.

Most modern garage remote use coded communication with anti-replay (they don't present the same code each time you press on the button)- not sure you can hack this so easily

otherwise it would be super easy for burglars; just stand next to the door when someone presses the button and record the IR pulse and then you could get in easily...

Hi thanks for the replay! No, I think they would need DIP SWITCH combination to do that.

Hi,
The encoding system is call "Rolling Code", the keyword changes with each Tx.

Tom... :slight_smile:

Most probably the DIP switch combination is used to have multiple remote controls work with the system. You would still have a rolling code

Thank all!! Ok sooo, I can never get the code! I'll have to do it in old school style, with a relay simulating pressing the button or is there some way to simulate two ports like relay? the final idea is to use a nodemcu or wemos d1 to do something small that does not bother the car

Thanks again

the hacking would really take getting a remote control, tear it appart and indeed simulating pressing the buttons... (and I'm not sure your neighbors might see that as very secure :slight_smile: )

Jejeje no, I mean pressing a buttto on my remote control not directly on garage door system!

yes got that - but still hacking a remote does create a risk...
