How small would you like it? 4 installation options

The maximum required clearance is only 32mm. There are 4 different ways to install occy® occupancy sensors. All necessary accessories are supplied. occy® uses digital PIR technology. This enables high sensitivity in a small design.

Occupancy sensors are no longer just installed on the ceiling. More and more clever smart home planners are using sensors also, e.g. to illuminate stairs, for night lighting at the bedside and many other ideas. Therefore occy® offers you 4 different installation options. Thanks to its small size and elegant design, there are various new and innovative installation options for your projects in addition to conventional ceiling installation. All necessary accessories are included:

  • Fix the wing nut with 2 adhesive pads
  • For wall thicknesses up to 1.8 mm

Installation variants for occy® (e.g.: sockets from KAISER)

White or black? Your choice. 

No two projects are identical. Sometimes white sensors are your best choice, especially if you want them to blend in perfectly and be almost invisible. In other projects, you might want to set visual accents and highlights. Also, if you project features grey or black ceilings, the occy® black edition might suit your requirements. You decide!

Customer Reviews

"Hello EPV, I would like to give my feedback regarding the new Occy Smarthome. I've had 2 occys now for over 3 weeks in use and am super satisfied. The installation was really a breeze. I use CAT7 cables which I connected to the powerpacks. This worked fine with the AWG23 cross section and the screw terminals on the powerpacks. All in all, the presence detector works flawlessly so far, looks great and the installation and commissioning were really easy. I also find the price-performance ratio quite reasonable compared to other sensors. Thank you for the new Occy - an enrichment for our SmartHome."  J.K. from W.


"The installation is very easy. 25mm drill bit, put on the appropriate cover and connect the cable, according to the very good instructions, with the PowerPack, plug the jack plug together. The detector makes a solid impression despite the small construction. Even the filigree springs hold the detector firmly to the ceiling. Thanks to the compact design, the simple commissioning and the functions offered, the detector is reasonably priced." S.B. from G.


"Hello, I would like to share the first experiences with the new occy motion detectors, also in comparison with the "older" variant, which are installed in the basement. Connecting the Cat cable to the Powerpack is much easier now, without additional resistors and clunky adapters with plastic sheathing. 

For one thing, the new sensor is installed in a hollow box with a blind lid at floor level. Placing the power pack in a hollow can is also straightforward, so the entire installation is done in less than 5 minutes. The range in the open living-dining area is even at 8m. Ceiling installation is also very simple. Powerpack connect, pushed into the dry ceiling and occy sensor with mini-aperture clipped in, ready!

In the Loxone Config there is nothing more to consider, no more input-side negating necessary. The inputs can thus be connected directly to the devices. Super is also during commissioning the green ring that lights up when moving, so you can see directly whether the BWM was connected correctly. Since the installation there are no problems, due to the small size they are not noticeable in everyday life, which is a problem with many other occupancy sensors in my eyes. If they are available to order again, we will reorder some more and equip the whole house with it." A.B. from H.
