3D impulse
for new switch ideas
With the combination of the ECO 200 kinetic energy generator
and the PTM 330 wireless module, EnOcean offers its OEM
customers an entire system for batteryless switch solutions. In
addition, developers can now request comprehensive 3D data
including all details of this self-powered pairing – and thus can
print prototypes of new switch designs very easily and fast.

Wireless control brightens the

Lighting technology has seen a huge innovation with the emer-
gence of LEDs and OLEDs. New, sophisticated control solutions
can further increase the convenience and energy savings realized
with these solutions. Energy harvesting wireless solutions uniquely
combine these benefits with easy installation while eliminating
maintenance effort. EnOcean LED lighting solutions therefore
unlock the full potential of this growth market.

Lighting control is becoming a focus for
building designers and owners as it is an
integrated part of legal regulations. With
Title 24, California set new standards for
building directives. It requires, for example,
that lights in unoccupied classrooms, hotels
and meeting rooms automatically switch off.
Such systems are required to save at least
15% of energy by adjusting the light level
dynamically to the amount of available day-
light or room occupancy.

In Germany, the Energy Saving Regulation
2014 (EnEV 2014) makes the automation
of building services mandatory for a build-
ing’s energy performance evaluation. The
same applies to recognized green building
certificates, such as LEED or BREEAM,
where intelligent control contributes to valu-
able rating points.

Wireless flexibility
In addressing these new regulations at a fast
return on investment (ROI), building design-
ers need to consider which networking tech-

Early this year, the EnOcean Alliance became a member of the
AllSeen Alliance to join forces for an Internet of Everything
(IoE). This connects the established EnOcean ecosystem to the
open source AllSeen Alliance community. We spoke with Philip

of collaboration.

Is it the fun factor what customers are looking for in a smart home? That’s all in the past. Smart
home systems have long since had to offer functions that do a lot more than just entertain.
Security and heath are high on the list of customer benefits. The solutions have to be reliable,
easy to use and competitively priced. Secure data transmission is also a matter of course. BSC

ments for a smart home solution:

Easy startup
All components communicate by radio and
are trained in the application using a QR
code and the smart phone app.

Reliability
The self-powered EnOcean switches and
sensors can be placed anywhere in the
house. Once installed, they require no main-
tenance.

User-friendliness
Users can run all functions from the individ-
ual components or a smart phone. Instead of
installing a gateway, they only have to con-
nect the camera and the existing Internet.
