API – cloud integration for selected partners

LK offers a cloud-based API for selected partners who want to integrate LK Arc and LK Cubic products into their own services. Access requires approval, and devices must be connected to LK’s cloud platform. Partners can retrieve status and measurement data, receive alarms, and in some cases control devices — securely via LK’s cloud with requirements for authentication and data protection.

The API solution is designed for professional integrations such as service platforms, property management systems, and other partner-specific solutions. For more information, please contact your LK sales representative.
