The Lufft I-BOX supports the visivility sensor VS20. Just install in the new App VS20 and start measuring.

The new App was released a long time ago for selected customers. Due to demand of customers we released the app to the App-Store. The App is available in Version 1.0.1.

The App supports UMB class 3 protocol. Since the VS20 sucessor VS20k also supports this protocol the App supports also VS20k.

The App is available for free.
