pykevoplus3
This is a Python3 fork of the original module for controlling Kwikset Kevo locks written by CSeelye.
Per Cseelye:
Kwikset does not provide an official API for their Kevo locks; I reverse
engineered this module from the mykevo.com web app.
To use this module you will need to have a Kevo Plus installed and a
registered account on mykevo.com. You will need your mykevo.com
credentials to use this module.
This module is published to pypi so you can install it simply via pip install pykevocontrol
Usage

The Kevo.GetLocks() function will attempt to scrape the mykevo.com web site to find your locks; as of this writing it can find all of your locks, but scraping the HTML might break at any time if Kwikset changes the website. This is broken as of 9 Sep 2019 due to recent CAPTCHA changes on the Kevo web site, however the KevoLock.FromLockID() method still works.

from pykevoplus import Kevo
locks = Kevo.GetLocks("username@email.com", "password123")
for lock in locks:
    print(repr(lock))

Output:

KevoLock(name=Front Door, id=cca7cd1d-c1d5-43ce-a087-c73b974b3529, state=Locked)
KevoLock(name=Back Door, id=c60130cd-8139-4688-8ba3-199276a65ad6, state=Locked)

A better way is to explicitly instantiate a KevoLock object using the UUID of the lock. You can get the lock IDs manually by logging into mykevo.com, click Details for the lock, click Settings, the lock ID is on the right.

from pykevoplus import KevoLock
lock = KevoLock.FromLockID("cca7cd1d-c1d5-43ce-a087-c73b974b3529", "username@email.com", "password123")

Locking and Unlocking

from pykevoplus import KevoLock
lock = KevoLock.FromLockID(lock_id, username, password)
lock.Unlock()
print(lock.GetBoltState())
lock.Lock()
print(lock.GetBoltState())

Output:

Unlocked
Locked

Multiple operations in the same session

The KevoLockSession context manager allows you to perform multiple operations on a lock with a single auth session

from pykevoplus import KevoLock, KevoLockSession
lock = KevoLock.FromLockID(lock_id, username, password)
with KevoLockSession(lock):
    lock.Unlock()
    lock.Lock()

Known Issues

• Error handling is extremely basic and needs much more work. Communication errors as well as lock bolt errors need to be addressed
• Alpha support for Python3
