The JUNG SV-Server app gives you direct access to your JUNG Smart Visu Server – and with it, your KNX visualisation. The Smart Visu Server makes your home smart: enjoy atmosphere, comfort and security at the tap of a finger. Lighting, blinds and shutters, heating and climate, music or IP cameras – you control and configure it all from your smartphone or tablet. The user-friendly Smart Visu Home interface makes every function and action easy to operate, and adapts automatically to your screen size. Several servers, one app New: manage several SV-Servers conveniently in one app and switch between them with a single tap – whether it's your home, your holiday home or the office. Set up each server's connection exactly as you need it: locally on your network only, via secure remote access through myJUNG only, or both. If both are set up, the app recognises where you are and switches automatically between the local connection and remote access. There's nothing for you to change. Your home, your rules Scenes and actions let you decide what happens together: dim the lights, close the blinds and start your favourite playlist – all with one tap. With the astro function, lighting and shading follow sunrise and sunset automatically, and the presence simulation gives you peace of mind when you're away for longer. You can adjust everything yourself, whenever you like, without waiting for an appointment.
