The VMBHIS is the hardware platform of choice for Stijnen Solutions Home center. A ready to use package to control your Velbus installation via iPhone/iPad, smartphone or PC/laptop. The plug consumes about 5W when fully functional. A green solution indeed. Besides the contents of the box, all you need is a functioning Velbus installation with a VMB1USB or VMBRSUSB communication module. You connect the Velbus USB interface and the network (Wi-Fi router is required for iPhone/iPad), then you only need to connect the VMBHIS.
