  • Installation


The control unit C4 can be connected to other ZigBee components from our Smart Home product line to control lamps, shutters or other electrical consumers. So, you can integrate more push-buttons, switches, motion sensors or twilight switches in your system.

The control unit C4 is to be considered as an additional option, which provides additional inputs. The components D1, S1, S2, J1 and their rail-mounted versions usually already have two inputs.

This component has 4 connectors for controls (inputs for switches or push-buttons). The connected push-buttons can be set up so that you can dim lights, turn on/off electrical consumers, control shutters or call up scenes, for example.

The control unit C4 fits into sufficiently deep DIN 49073 tins and can be placed flush-mount behind any socket, behind any light switch or into a wall or ceiling outlet — You will not have to replace any existing switches or sockets. Even if you only want to replace the old switches for aesthetic reasons our solution will keep you flexible in your choices. Simply select any range of switches and any manufacturer that you prefer and combine them to your liking. Only unconventional switches, e.g. those installed in bus-systems (KNX/EIB) are incompatible. Being amongst the flattest in-wall modules, if not the flattest available on the market today, installation comes very easy. The wireless components used in smart home system by ubisys are based on the international standards IEEE 802.15.4 and ZigBee. This guarantees long term availability of all components thus protecting your investment. Due to the resilient and innovative radio controlled technology there are no special skills required when installed. This solution not only makes it ideal for new buildings but also for redevelopments and renovations. Additional components can be added and perfectly integrated into your smart home by and by. This leaves the decision when and how extensively you want to expand your system entirely up to you. And with the Over-the-Air (OTA) firmware upgrade, this component — as well as all other smart home components — will always stay up to date. This makes you well prepared for the future „Smart Grid„.

Note regarding Philips hue:
Even though the Philips hue bridge/app currently supports the ZigBee 3.0 standard, not all device types are displayed in the hue app. For the time being only our ubisys D1 (-R) can be controlled with the hue app – our products S1 (-R), S2 (-R) and J1 (-R) unfortunately not. When and to what extent the hue app will support other ubisys products is beyond our knowledge.

Our ubisys Gateway G1 as well as our components C4, D1 (-R), S1 (-R) and S2 (-R) can control Philips hue illuminants, though.
