Lumo at a glance

On-Hertz Lumo is a complete mobile radio studio in a simple and intuitive software. It is more than a radio automation system or transmission software. Lumo is intended to facilitate outside broadcasting and bring extreme mobility to radio makers.

"Lumo empowers you to make radio differently."

June 2026 - Lumo software deprecation effective immediately

With the addition of the Playlist and Launchpad nodes, along with the Panels interface designer in Artisto, Lumo's purpose has significantly diminished.

Users can now recreate the same workflow in Artisto and utilize its additional benefits.

By discontinuing Lumo, our R&D Team will be able to focus on other products, enhancing our overall development speed and helping us bring our exciting roadmap to life even faster.
