# Voldeno

> Voldeno is a wired, local-first building automation system. Modules mount on DIN rail and talk over the Voldeno Bus (CAN-FD). Automation logic runs as Logic Blocks distributed across the modules themselves, or is written in Volang and executed by the VolangVM embedded in every module. Installers configure systems in Voldeno Studio; users control them from Voldeno Mobile. No cloud dependency and no subscriptions.
