  • If using a webhook, an app server up and publicly accepting lifecycle events (needs url) from SmartThings via HTTPS.
  • Verify your domain ownership
  • If using Lambda, permission to execute your Lambda (url) function must be granted to SmartThings.

Types of SmartApps​

There are typically three types of SmartApps you can create. Which one you choose will depend entirely on your specific application. Choosing to start with a Simple SmartApp will not preclude you from enabling more advanced features later.

Simple SmartApp​

If you need to create something more complex than a rule, but do not need to hold outside authentication information or other data, you will use a simple SmartApp. We have created an example tutorial on building a simple SmartApp that sets the color of a light based on the weather in a given zip code.

Services with a Complex SmartApp​

If your SmartApp needs to allow external communication or authentication with a third party, you will need a context store. We have created a tutorial on building a SmartApp with Context Store here:

Cloud Connected Devices with SmartApp Connectors​

It is possible to create and control cloud connected devices with a SmartApp. For more complete instructions on how to work with cloud connected devices please visit the Devices documentation section.

Create Your SmartApp With the SmartApp SDK​

There are two SDKs available to help create your SmartApp.

The SDKs are a set of libraries and wrappers around the SmartThings API designed specifically for SmartApp creation.
