This adapter makes it easy to access all the features of a Multiplus both statically (using VE.Configure) and dynamically (using Venus OS and Node Red). I consider it a "must" for any VE.Bus system.

Worked like a charm with MacBook

Higly recommended this purchase, especially if you don't have the Cerbo GX for updates.
