Garage Server

A server for Raspberry Pi to open a garage door. Used by garage-ios.

Hardware I used for project:

1. Magnetic Reed Switch (Optional. Used for door status)
2. Relay Shield Module

I really like the above relay because when the power is disconnected and restored (i.e. power goes out in the middle of the night) the relay will remain off. That way a power outage won't open your garage door.

Options

  -cert string
    	TLS certificate path (e.g. /certs/example.com.cert)
  -http string
    	HTTP listen address (e.g. 127.0.0.1:8225)
  -key string
    	TLS key path (e.g. /certs/example.com.key)
  -log string
      Path to read logs from
  -pin int
    	GPIO pin of relay (default 25)
  -sleep int
      Time in milliseconds to keep switch closed (default 100)
  -status-pin int
    	GPIO pin of reed switch (default 10)
  -version
    	print version and exit

NOTE: Providing a cert and key will infer the use of TLS

Installation Instructions

Installation Steps Overview:

1. Download garage-server
2. Create init.d script
3. Configure init.d script

Download garage-server

Install from source

Make sure go is installed on your Raspberry Pi and then you can use go get for installation:

go get github.com/dillonhafer/garage-server

Install from binary

If you don't have/want to setup go on your Raspberry Pi you can download a pre-built binary. Remember to download the init.d script 😉

Latest binaries available at https://github.com/dillonhafer/garage-server/releases/latest

Create init.d script

Simply copy the init.d script from the src directory.

cp $GOPATH/src/github.com/dillonhafer/garage-server/garage-server.init /etc/init.d/garage-server

Configure init.d script

The last thing to do is to configure your init.d script to reflect your Raspberry Pi's configuration.

First set the GARAGE_SECRET environment variable. This will ensure JSON requests to the server are authenticated. Be sure to use a very random and lengthy secret.

Just un-comment the following line and add your secret in the init.d script:

# /etc/init.d/garage-server...

# Remember to set a very strong secret token (e.g. ad23384951c79a42b898e273580564d90e4eee22ad2474cf67475f323817a9ed7640a)
# DO NOT USE the above secret. It's an example only.
GARAGE_SECRET=ad23384951c79a42b898e273580564d90e4eee22ad2474cf67475f323817a9ed7640a

Other configuration variables to consider are the HTTP_ADDR and PIN. Use these to set what address the web server should listen on and what GPIO pin your Raspberry Pi is configured to use.

# /etc/init.d/garage-server...

HTTP_ADDR="0.0.0.0:8225"
PIN=25
STATUS_PIN=10

Now just install and start the service:

sudo chmod +x /etc/init.d/garage-server
sudo update-rc.d garage-server defaults
sudo service garage-server start

And then verify that it's running:

sudo lsof -i :8225

should return something like:

COMMAND    PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
garage-se 3401 root    3u  IPv4   9111      0t0  TCP *:8225 (LISTEN)

That's it! The server is now setup!

Updates

You can update your server with the latest binary with the update command in the init.d script.

You can keep your server automatically up-to-date with cron:

@daily /usr/sbin/service garage-server update && /usr/sbin/service garage-server restart
