The Küng HMI consists of a touch display that relies on a Linux operating system and uses an integrated progressive web app (PWA), which is built with the same languages as a website: HTML and CSS. PWAs function on the web rather than residing on a hardware device like a smartphone or computer, so they don’t take up storage space and they’re quick and easy to update.
The initial problem Küng had was in providing clients with remote access to the Küng smart control system from any device, passing right through any firewalls. In short, the company needed a fast, efficient, and secure connection method. Küng was able to achieve that by using Nabto’s P2P application-level tunnel solution.
The Nabto platform provides a TCP (Transmission Control Protocol) tunnel that reduces latency in machine-to-machine communication. The TCP tunnel bypasses firewalls and allows real-time communication across different network protocols and devices.
