Getting Started

Welcome to the SeltronHome Cloud API

Before you start integrating with the SeltronHome Cloud API, please ensure the following prerequisites are met.

Prerequisites

1. SeltronHome (Clausius) Mobile App and Account

To use the SeltronHome Cloud API, you must have an existing SeltronHome (Clausius) account.
This account is created through the Clausius mobile application, available for both Android and iOS:

Within the Clausius App, you can register and configure your Seltron devices and ensure they are connected to the SeltronHome Cloud.
Only devices that are visible and online in the mobile app can be accessed via the Cloud API.

2. Developer Portal Account (Linked via SSO)

Access to the SeltronHome Developer Portal requires sign-in using the same credentials as your Clausius App account.
The Developer Portal provides Single Sign-On (SSO) between the Clausius App and the Developer Portal.

This means that your Clausius account is automatically linked to your Developer Portal profile — no additional registration is required.

When signing in for the first time, you’ll be redirected to the SeltronHome identity page, where you can:

  1. Enter your email address associated with your Clausius App account.

  2. Verify your email address by entering a verification code sent to your inbox.

  3. Confirm your profile details (name, display name).

  4. Complete the process — your Developer Portal account is automatically linked to your SeltronHome identity.

How to Start Using the API

Once your account and devices are ready, follow these steps to begin using the API:

  1. Sign in to the SeltronHome Developer Portal.

  2. Explore available APIs using the integrated API documentation — including OpenAPI specification and “Try It” functionality.

  3. Subscribe to one of the available products (Basic or Premium) to obtain your subscription key.

  4. Call the API by including your subscription key in the request header: X-Api-Key: {your-api-key}
