10. Wireless mesh network
All modules communicate with each
other in the Plugwise network.
Additionally, each module functions
as a router.
A switching command to a certain
plug is automatically transmitted
via the most efficient route
(circumventing obstructions).
If for any reason the route is blocked…
…the system will automatically
choose the second most efficient
route.
Be wise, plug in.

11. The wireless mesh network
Plugwise networks can
easily be extended with
other modules.
Be wise, plug in.

12. ZigBee technology
ZigBee is a reliable, robust, self healing RF-
technology for monitoring and control :
• Open international standard (adopted by many utilities)
• Full dynamic ‘MESH’ network support
• Plugwise’s profile has highly secure authentication via 128-bit AES
encryption
• Based on Zigbee Pro with a manufacturing specific profile but
accessible (with key) to other non Plugwise-systems
• Highly resistant to interference from other wireless systems
• Upgradable over-the-air (OTA)
• Easily extended with additional plugs or multiple networks
• Plugwise’s system is uniquely developed to support very large
professional networks (1000’s)
• Every device has its own unique MAC-address (and each device
can be individually and uniquely identified with its location)
Be wise, plug in.

13. Certifications
• Compliance with European R&TTE directive confirmed by TüV
Rheinland
• Safety and electro-magnetic compatibility (EMC) guaranteed
with KEMA-keur and GS (Geprüfte Sicherheit), approved by
CEBEC

• No room in a building, whether home or office, is in use all the time
• In this case only 38% percent of the year sees activitiy and during the
rest of the time many devices like lights, PCs, printers, coffee machines
are left operational - wasting energy

30. Phases of a customer Implementation
•First Meetings
Pre Installation •Costing Established
Phase
•Day 1 - Day 14
•Understand the Energy Used
Phase 1
•Day 15 - 30
•Measurement and Control – set up the Plugwise system
Phase 2 •Go - No Go
Customer agrees to an Installation
• Money back guarantees
Customer Enjoys up to 40% savings in Energy Use
• ROI in 1 to 3 years
Be wise, plug in.

31. Pre Installation
• Focuses on creating a clear picture of the costs, where and what type of
device can to be used to save power.
• A "standard" pre-installation process will begin with a meeting to present
Plugwise & allow us to fully assess the scale of the project and give a good
estimate to produce a tender with costing and ROI times.
• Once the tender is approved we discuss how Plugwise can implement a
solution
• A second appointment will be also organized with Facility Management to
do an inventory check of the devices mostly likely to be wasting energy.
• We will fully evaluate the customer’s site and will indicate the types of
device to be used and where they can be located to give 95% coverage of
the location.
• The final step is to ensure the customer fully understands the Plugwise
proposal in order to sign an agreement for its implementation.
Be wise, plug in.

32. Phase 1
• Understanding the energy used by the customer.
• Measurement of energy only to get a good understanding of how to
optimise the programming of the system
– The plugs are not programmed in this phase and just act as autonomous energy
measurement devices to record all energy measurement in their Flash memory.
• After 2 weeks of pure measurement, a review date will be scheduled. The
largest energy consuming devices will be identified, energy consumption
will be measured against known averages and potential savings will be
shown and explained.
• Immediately after this first review the switching schemes are
implemented on all the plugged devices and names and grouping
established.
Be wise, plug in.

33. Phase 2
• Minimise energy consumption by programming the monitoring and
control functions of a number of key plugged devices identified from
Phase 1
• This is made possible by programming the on / off times of the Plugwise
system via the source software and activating standby killers in the device.
• Additionally it’s possible to get feedback from Phase 1 on the most
efficient use of energy to users & initiate behavioural change within the
company.
• After the Phase 2 review a clear picture of the energy consumption of the
devices outside office hours will be given and lists made of the top 20
largest energy wasters.
Be wise, plug in.

34. Final Phase
• At this stage customers decide whether the Pilot of the
Plugwise system has been convincing enough to be
implemented in either in full or part.
• After a 'GO' separate arrangements will be made for the
expansion and or optimization of the system.
– This will normally be within 2 weeks of final sign off.
