augustpy

Because the August Connect is far too expensive. Heavily inspired by the abandoned augustctl project and its many forks.

Setup

These instructions are currently for Linux only. The Raspberry Pi 3 and newer are supported, as well as the Zero W.

Automated setup

Simply run setup.sh to install requirements and configure permissions. Root access is required.

Manual setup

Setup basic packages:

  $ sudo apt-get install python3 python3-pip libglib2.0-dev

Clone repo to desired location and enter the folder.
Install Python requirements:

  $ pip3 install -r requirements.txt

[Recommended] To use Bluetooth LE scanning functionality as non-root, give direct permissions to bluepy-helper:

  $ sudo setcap 'cap_net_raw,cap_net_admin+eip' $(echo "$(pip3 show bluepy | grep Location: | cut -c 11-)/bluepy/bluepy-helper")

Configuration

Communication with the lock is encrypted using a hidden key stored within the August app. In order to control and monitor your August lock with this program, you must first find this key.

Android Phone

Root is required to access the data. If your phone is not rooted, you may be able to setup a rooted Android virtual machine, install the August app on it and extract the necessary data from there.

If the phone is rooted, you can copy the settings file /data/data/com.august.luna/shared_prefs/PeripheralInfoCache.xml from your phone to your computer. Apps such as Solid Explorer can do this, or you may use adb shell.

Open PeripheralInfoCache.xml and find the bluetoothAddress, handshakeKey and handshakeKeyIndex strings. You should find something like this:

&quot;bluetoothAddress&quot;:&quot;0A:1B:2C:3D:4E:5F&quot;,&quot;handshakeKey&quot;:&quot;ABCDEF0123456789ABCDEF0123456789&quot;,&quot;handshakeKeyIndex&quot;:1

Copy the values found between the " delimiters (here, 0A:1B:2C:3D:4E:5F, ABCDEF0123456789ABCDEF0123456789 and 1, respectively).

iPhone

The key and offset can be found in plist located at:

User Applications/August/Library/Preferences/com.august.iossapp.plist

This can be retrieved by using a file explorer like http://www.i-funbox.com/ifunboxmac/, and opening the plist in Xcode.

Putting it all together

Paste the values you've found in a file named config.json in the folder you wish to execute augustpy from, like so:

{"bluetoothAddress": "0A:1B:2C:3D:4E:5F", "handshakeKey": "ABCDEF0123456789ABCDEF0123456789", "handshakeKeyIndex": 1}

If you have more than one lock, you may instead define an array of locks, like so:

[
  {"name": "front", "bluetoothAddress": "0A:1B:2C:3D:4E:5F", "handshakeKey": "ABCDEF0123456789ABCDEF0123456789", "handshakeKeyIndex": 1},
  {"name": "back", "bluetoothAddress": "6A:7B:8C:9D:0E:1F", "handshakeKey": "ABCDEF0123456789ABCDEF0123456789", "handshakeKeyIndex": 1}
]
