Get started with Yale Locks

Learn how to connect and control your Yale lock with the Seam API.

Overview

Seam provides a universal API to connect and control many brands of smart locks. This guide provides a rapid introduction to connecting and controlling your Yale lock using the Seam API. Note that this guide is intended for Yale locks connected via the Yale wifi bridge and Yale access app. For Z-Wave Yale devices, head over to our guide for SmartThings.

To learn more about other smart lock brands supported by Seam such as August, Schlage, and Salto, head over to our integration page.

1 — Install Seam SDK

Seam provides client libraries for many languages, such as JavaScript, Python, Ruby, PHP, and others, as well as a Postman collection and OpenAPI spec.

npm i seam

Once installed, sign-up for Seam to get your API key, and export it as an environment variable:

$ export SEAM_API_KEY=seam_test2ZTo_0mEYQW2TvNDCxG5Atpj85Ffw

This guide uses a Sandbox Workspace. Only virtual devices can be connected. If you need to connect a real Yale Lock, use a non-sandbox workspace and API key.

To control your Yale lock via the Seam API, you must first authorize your Seam workspace against your Yale account. To do so, Seam provides Connect Webviews: pre-built UX flows that walk you through authorizing your application to control your Yale lock.

Note that yale_access or yale_home are now deprecated in favor of justyale which will work with whichever version of the Yale backend.

Request a Connect Webview

from seamapi import Seam

seam = Seam()

webview = seam.connect_webviews.create(accepted_providers=["yale"])

assert webview.login_successful is False

# Send the webview URL to your user
print(webview.url)

Authorize Your Workspace

Navigate to the URL returned by the Webview object. Since you are using a sandbox workspace, complete the login flow by entering the Yale sandbox test accounts credentials below:

  • email: jane@example.com

  • password: 1234

  • 2-factor-auth: 123456

Confirm the Connect Webview was successful by querying its status:

updated_webview = seam.connect_webviews.get(webview.connect_webview_id)

assert updated_webview.login_successful # true

3 — Retrieve Yale Lock Devices

After a Yale account is linked with Seam, you can retrieve devices for this Yale account. The Seam API exposes most of the device's properties such as battery level or door lock status.

all_locks = seam.locks.list()

some_lock = all_locks[0]

assert some_lock.properties["online"] is True
assert some_lock.properties["locked"] is True

print(some_lock)
# Device(
#   device_id='b013d947-cef1-4dfe-8aa2-1e452eca5262',
#   device_type='yale_lock',
#   location=None,
#   properties={
#     'locked': True,
#     'online': True,
#     'door_open': False,
#     'manufacturer': 'august',
#     'battery_level': 0.9999532347993827,
#     'august_metadata': {...},
#     'name': 'BACK DOOR'},
#     capabilities_supported=['access_code', 'lock']
#     )

4 — Locking & Unlocking a Door

Next, you can perform the basic action of locking and unlocking the door.

Unlock a door

POST https://connect.getseam.com/locks/unlock_door

Request Body

NameTypeDescription

device_id

String

# lock the door
seam.locks.lock_door(some_lock)
updated_lock = seam.locks.get(some_lock.device_id)
assert updated_lock.properties["locked"] is True

# Now unlock the door
seam.locks.unlock_door(some_lock)
updated_lock = seam.locks.get(some_lock.device_id)
assert updated_lock.properties["locked"] is False

5 — Setting Access Code on Yale Lock

Most Yale locks come with a keypad built-in to program access codes. These codes can then be entered to unlock a Yale lock.

The Seam API makes it easy to program both ongoing codes and timebound codes on a Yale lock. You can find out more about Yale lock access code in our core concept section on access codes.

# create an ongoing code
seam.access_codes.create(
    device=some_lock, code="123456", name="Personal Access Code"
)

# create a timebound code
seam.access_codes.create(
    device=some_lock,
    code="888888",
    name="My Temp Access Code",
    starts_at="2028-08-12T19:23:42+0000",
    ends_at="2028-08-13T19:23:42+0000"
)

# you can use a device or a device_id as the "device" parameter
seam.access_codes.list(device=some_lock)
# [
#   AccessCode(
#     access_code_id='af5272b1-2a49-4eb5-9388-2447fc7b5bd1',
#     type='ongoing',
#     code='123459'
#   ),
#   AccessCode(
#     access_code_id='8c2db4da-b137-4c08-a2c3-d611e6ff91b3',
#     type='timebound',
#     code='888888',
#     starts_at='2028-08-12T19:24:00.000Z',
#     ends_at='2028-08-13T19:24:00.000Z',
#   )
# ]

Next Steps

Now that you've completed this guide, you can try to connect a real Yale device. To do so, make sure to switch to a non-sandbox workspace and API key as real devices cannot be connected to sandbox workspaces.
