The Belimo Cloud Extension for SkySpark is a connector for the Belimo Cloud API.

The Belimo Cloud is a great place to store and monitor all your Belimo Energy Value data. The Belimo Cloud extension shows how easy it is to connect to the Belmio Cloud API to retrieve and and analyse your device data.

Like all good SkySpark connectors, the Belimo Cloud extension provides:

  • Learn functionality - browse and bind Belimo devices and datapoints from within the SkySpark Connector and Builder applications
  • Current values - poll the Belimo Cloud API for datapoint current values
  • Point write - write new datapoint values to the Belimo Cloud
  • History sync - download datapoint history data in bulk

This connector has been developed for SkySpark v3.1 (or later), the Belimo Cloud Client-API v3, and makes use of the SkySpark v3 connector framework. For compatibility with SkySpark v3.0, download Belimo Cloud Extension v1.0.2.

Quick Start

  1. Install afBelimoCloudExt (use SkySpark's Install Manager)
  2. Create an instance of the "afBelimoCloud" connector
  3. Set your Belimo Cloud username and password
  4. Set your Belimo Cloud Client (ID and Secret) Credentials with the Axon function:
    • afBelimoCloudSetClientCredentials(connectorId, "<clientId>", "<clientSecret>")
  5. Bind your Belimo data points

Belimo Cloud API Credentials

The Belimo Cloud Extension has been developed according to the Belimo Cloud Developer Space directions. To use the Belimo Cloud extension, you must acquire TWO sets of credentials:

  1. A Client ID and a Client Secret.

    This defines the realm of Belimo devices accessible to you. Facilities managers will receive their own unique credentials.

    Developer Client Secrets rotate on 60 day basis. Belimo provides also a static set of credentials on request.

  2. A Username and Password.

    This identifies you as an individual.

Both sets of credentials are required by the Belimo Cloud extension, you can obtain them following the instructions at

Note, if you change any credentials - all affected Belimo Connectors need to be disabled and then re-enabled for the changes to take effect.

Your First Belimo Cloud Connector

Belimo Cloud connectors are created in the usual way with the SkySpark connector application. On creating a new Belimo Cloud connector you will be prompted to enter your username and password.

To complete your connector setup, and before it can be enabled, you must first set your client credentials on the connector. Do this by running the following (Admin) Axon command:

read(afBelimoCloudConn).afBelimoCloudSetClientCredentials("<clientId>", "<clientSecret>")

You should then be able to enable your connector and successfully ping the Belimo Cloud API.
