Get started with SmartThings Hubs + Smart Locks

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 SmartThings Hub and smart lock using the Seam API. SmartThings Hub is connected to your local network using either Wi-Fi or Ethernet. The smart lock is paired to SmartThings via Zigbee or Z-Wave. These locks can then be remotely locked, unlocked, and have access codes programmed to allow keyless entry.

To learn more about other smart lock brands supported by Seam such as August, Yale, 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.

JavaScript / TypeScript (npm, GitHub)
Python (pip, GitHub)
Ruby Gem (rubygem, GitHub)
PHP (packagist, GitHub)
Java (GitHub)
C# (nuget, GitHub)
Go (GitHub)

npm i seam

Gradle:

// build.gradle
dependencies {
    implementation 'io.github.seamapi:java:0.x.x'
}

Maven:

<!-- pom.xml -->
<dependency>
    <groupId>io.github.seamapi</groupId>
    <artifactId>java</artifactId>
    <version>0.x.x</version>
</dependency>

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. You can only connect virtual devices in a sandbox workspace. If you need to connect a real device, use a non-sandbox workspace and API key.

2 — Link Your SmartThings Account with Seam

To pair a SmartThings Hub and smart lock with our API, you must sign in to a SmartThings account. To do so, create a Seam Connect Webview.

from seam import Seam

seam = Seam()

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

assert webview.login_successful is False

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

import { Seam } from "seam"

const seam = Seam()

const webview = await seam.connect_webviews.create({
  accepted_providers: ["smartthings"]
})

console.log(webview)
/*
{
  "connect_webview_id": "811b80e7-7c87-4ce1-a938-2f6936851aa9",
  "url": "https://connect.getseam.com/v1/connect_webviews/view?connect_webview_id=811b80e7-7c87-4ce1-a938-2f6936851aa9&auth_token=GXtMoAaperbuNhSCByyQMroT9HMRquXK6",
  "device_selection_mode": "none",
  "accepted_providers": [
      "smartthings"
  ],
  "created_at": "2022-01-03T21:11:27.002Z",
  "login_successful": false,
  "status": "pending"
}
*/

require "seam"

seam = Seam.new(api_key: "MY_API_KEY")

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

puts webview
# <Seam::ConnectWebview:0x006a950
#   url="https://connect.getseam.com/connect_webviews/view?connect_webview_id=123e4567-e89b-12d3-a456-426614174000&auth_token=q123DASDASKd23DADdad29"
#   status="pending"         
#   created_at="2022-07-06T23:20:09.785729+00:00"
#   workspace_id="123e4567-e89b-12d3-a456-426614174000"
#   accepted_devices=[]
#   login_successful=false
#   accepted_providers=["smartthings"]
#   any_device_allowed=nil
#   connect_webview_id="123e4567-e89b-12d3-a456-426614174000"
#   custom_redirect_url=nil
#   any_provider_allowed=false
#   device_selection_mode="none">

Now, send the Connect Webview URL to the user. When the user signs in, you see a "completed" status on the Connect Webview or login_successful set to true.

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

assert updated_webview.login_successful

You can now find all the devices that are associated with the connected account. From the returned payload, see whether the door lock is locked or unlocked.

from pprint import pprint

all_devices = seam.devices.list()

some_device = all_devices[0]

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