Overengineer your garage door with your Raspberry Pi!
Use a Raspberry Pi to open or close your garage door and to sense whether it's currently open. You can do this from the comfort of your couch or anywhere in the world (with an appropriate VPN connection). Your spouse may think you're crazy, but it's so cool!
I started with this guide by Chris Driscoll at Driscosity. Chris has an awesome guide with step-by-step instructions, pictures, and even a video of the system in operation. I use this same hardware setup for GaragePi.
So I wrote a Flask app (Python) with some JSON/jQuery for keeping the status updated. I also used Bootstrap for the front end. All these are new to me so forgive / correct any noob mistakes.
Dec 2020 Update - Added Telegram Notifications
GaragePi now supports Telegram notifications. Get your Bot key and chat ID and place it in the app.cfg file to enable telegram notifications. You can read more about getting this information from the apprise wiki https://github.com/caronc/apprise/wiki/Notify_telegram
Oct 2020 Update - Added Crack Open Garage Feature
GaragePi under this fork now has an option to crack open the garage. The fuction is a simple time-delay that triggers the relay twice. The button to crack the garage does not have a modal confirmation, so to make the UI more consistent I removed the modal confirmation from the original open button.
Modifiy the time delay in the app.cfg file to make it work for your garage.
Feb 2016 Update - IFTTT Maker Support!
See below for alert details and how to set them up.
I also pulled the app into two parts, one for the webserver and one that's always running and talking to the RPi. This makes it so the webserver doesn't have to run with root privileges. More importantly, this also enables a whole lot of other features that require running all the time instead of just within a web request.
- Open / close the garage door with the press of a button.
- See if garage door is currently open.
- See history of when the door was opened or closed even when it wasn't opened/closed using the app.
- Download entire history to CSV file
- Garage door activity generates IFTTT events.
- Responsive UI for both desktop and mobile use.
- Show the RPI's internal temps because, well, I can.
I'm definitely planning on getting these done.
- Make the password configurable. You can change it yourself, but you have to edit a config file.
Send an alert if the door is open past a certain time. (I'm always leaving the door open all night.)Done!
Okay, I might never implement these, but here are some ideas for what would make it even better (read more overengineered).
Add a function to open the door just partway for ventilation.
- Close the door automatically at a certain time or after a certain amount of time.
- Show stats of how much time the door is open, what hours it's most open, or other interesting trends.
Follow all the instructions at Driscosity up until the point where he has you installing WebIOPi. Basically, just do the hardware bit and the RPi environment setup.
Run the fully automated installer by running this command logged into your Raspberry Pi.
curl -s "https://raw.githubusercontent.com/nathanpjones/GaragePi/master/setup/online_install.sh" | bash
It will take a while for the setup scripts to run, but at the end you should be able to access your site at your Raspberry Pi's IP address.
The online install will put everything in
~/garage_pi. Look to the
instance subfolder for the app logs and the
If you want to pull down the repo manually (recommended if you want to choose where to install), all you have to do is navigate to the project root folder and run the following command.
The app configuration file is found in
- Navigate to the project root. If you used the online installer, run
nano instance/app.cfgto open the config file.
- Locate the
PASSWORDfield and change it from the default to something unique for you. You may also change the login
USERNAMEif you like.
- Set the
REED_PINif your hardware configuration differs from the Driscosity setup.
- Have a look through the other settings such as the IFTTT settings to see if any other changes are appropriate.
- Press CTRL+X. Answer Y when prompted to save and then press Enter to overwrite the existing file.
I've included an uninstall script. You can run it with the following command.
This isn't a complete uninstall because I don't keep track of everything you had installed when you started. It does remove the GaragePi related services and lets you know what else you might want to remove.
Once you've run the uninstall script, it's safe to simply delete the project root folder.
rm -rf ~/garage_pi

To enable IFTTT events, you must first obtain your maker key. You should see listed on the front page of the Maker Channel.
- Open up
- Locate the line that starts with
IFTTT_MAKER_KEYand input your maker key between the single quotes. It should look something like,
IFTTT_MAKER_KEY = 'c-jfLKBJEfijas3r28VBL'
- If you want to use the door warning, change
DOOR_OPEN_WARNING_TIMEto the desired time. Make sure to use 24-hour format with just hours and seconds, for example,
DOOR_OPEN_WARNING_TIME = "18:30"
