The ubisys Smart Home app allows you to dim lights, switch sockets on and off, control shading, set a cozy temperature, setup a security system, measure your power consumption and many other things. Your data remains completely on the ubisys Gateway G1 and is never transferred to the cloud. This guarantees your privacy. Stand-alone operation in local networks for high reliability and fast response times; an internet connection is only required for push notifications and remote access. Even while on the road, the app always connects to your gateway directly - without taking a cloud detour. The same applies to automation templates: They run autonomously on your gateway reacting quickly and reliably to sensor notifications. The components form a wireless Zigbee network and can be operated by smartphone and tablet. Of course you can still use all existing switches to turn your lights on and off. Devices can also be grouped together and incorporated into scenarios of your choosing. With the push of a button you will experience the perfect feel-good atmosphere or the ideal working environment. Using the "Leave home" scenario you can switch off all non-essential consumers. Existing switches and push buttons can be configured to switch on and off various other consumers, dimm the lights, recall scenes etc. Countless options offered by various kinds of timers facilitate automating regular tasks, e.g. open the window blinds in the mornings and close them in the evenings or run light scenes during your holidays to simulate presence. As easy as setting an alarm clock. Even the most compelling automations can be realized using JavaScript modules, which run on the gateway. With our built-in bridge your whole system is even available to Matter controllers as long as both ends support a specific device type. To be able to use the app to its full extent you will require the ubisys Gateway G1 as well as an assortment of Zigbee components. Alternatively, this app can be used in connection with a Zigbee Direct capable device like the ubisys LD6 or S1-R Series 2 - without Gateway G1. Let our portfolio of professional ubisys Zigbee units amaze you: LED Controller LD6, Universal Dimmer D1, Power Switches S1/S2, Shutter Control J1, Thermostatic Radiator Valve H1, or Underfloor Heating Control H10 all integrate into a whole-home solution. They are flush mounted behind existing light switches, sockets, shutter controls and shutter boxes, or a simple power outlet and even put in a lamp - therefore totally invisible. Further variants are available for installation in fuse cabinets. All ubisys Zigbee components are kept up to date via wireless firmware updates. We also redistribute the latest firmware for devices made by third party vendors when such updates are available. The ubisys Smart Home platform is open to compatible Zigbee products of third parties. This includes certified Zigbee 3.0 products, including energy-harvesting battery-less switches and sensors built using Zigbee Green Power. Products with poor Zigbee implementations might not work as expected. We are constantly adding new products to our offering. You'll find a selection of devices, which are guaranteed to interoperate, in our online-shop at www.smarthome-store.de.
