Seemed ridiculous to replace my existing garage door openers or to buy an expensive add-on just so I can have Siri open my garage door. Since I already had a Pi laying around, I figured adding a few reed switches and relays would not hurt.
- Raspberry Pi with at least 3 GPIO pins available per door you want to control
- 2 reed switches (NO)
- Some form of a relay (I use a Sain Smart relay)
This project uses dep for dependency management. You will need that installed before you can build.
$ clone this repo $ dep ensure $ VERSION=sem.version.number make
Use the wiring diagram below to assist you in wiring up the Pi to your relay and switches. If you are not using a Sain Smart relay, you will most likely not need the circuit documented below or will need a different circuit.
You will need to position the two reed switches in a way that the "bottom" is in a closed state when the door is in the closed position and the "top" switch is in a closed state when the door is in the open position.
Once everything is wired up, configure piragekit and run it. Launch Home on iOS and tap +, tap Add Accessory, tap "Don't Have a Code or Can't Scan?". You should see PirageKit show up as a square. Tap it and enter the code you configured earlier.
