Wattson used in Healthy Living flats - Hong Kong

Wattson Classic, Silver Lining, featured in Wall Street Journal Asia, Life & Style, Homes.


Wattson Classic in HK

Developer and co-owner Henning Voss is re-envisioning this 880-square-foot home in Hong Kong's Sheung Wan district by addressing health and environmental concerns.

Many features are neatly hidden in the construction of the space, including an advanced air purifier, which filters out volatile organic compounds, or VOCs, and formaldehyde. Also, a number of living air filters in the form of plants are scattered throughout the apartment. They provide both an organic aesthetic and an efficient filter for hazardous airborne particles.

This Wattson Classic energy monitor glows red when usage is high, and it will send energy consumption data wirelessly to a mobile device.

Look out for the next development in MAR 2014 - Creating Health at Home.

Behavioral insights for sustainable behavior

Source:, published on 19th August 2013 by Amira Choueiki (Deloitte)

We all know ‘being green' can be a challenge. Whether it's remembering to take your reusable grocery bags to the store, waiting to pass by a recycle bin to toss your soda can, or riding the metro instead of hailing that cab, environmental friendliness often requires extra effort. However, we also know that collectively, these small choices can have a huge impact. Finding ways to encourage green behavior often demonstrates one of the areas that can be most difficult as it requires citizens to go against several of the ‘defaults' of human behavior - but effective tools exist. Here are a few examples.

Prime waste management with visual cues. In results published by the Danish Nudge Network (DNN) in March 2013, a reduction in food waste was directly related to plate size provided to conference attendees. At the Danish Executive Summit, two buffet lines offered two separate plate sizes - in the control group, the normal 27 cm diameter plate was offered, while in the treatment buffet line, a 24 cm diameter plate was set. All remaining food waste was collected following the luncheon and weighed, with outstanding results. The group using the smaller, 24 cm plate produced 26% less food waste than the group with the larger 27 cm plate - confirming the hypothesis that a subtle change in environment - in this case, a plate size - could influence sustainable food portioning.

Prior to this experiment, in 2011 DNN used visual cues to prime people's tendency to dispose of their garbage responsibly. In round one, researchers passed out caramel candies to passing pedestrians. Soon after, they carefully counted wrappers found in trash cans, ashtrays, bike baskets, and surrounding streets. In round two, they handed out the same candies but placed green footprints on the ground leading to nearby trash cans. Astonishingly, this resulted in 46% fewer wrappers found in inappropriate places. This concept is being applied in all sorts of ways - Wattson (which shows your household energy use and associated cost at a given time) and eFergy Showertime (which shows your length of shower and amount of water used in comparison to a set target) serve as reminders of energy and water use - visually priming in a simple, straightforward way. As the design of new smart meters and grids are developed, there is potential to consider these visual cue aspects to encourage responsible household resource use.

Make it a game. Organizations like Recyclebank have taken a carrot rather than stick approach to behavior change. They partner with companies to creatively incentivize recycling programs. Participants can ‘cash in' recycled goods for points, earning them discounts and credit at popular stores such as Target and Barnes and Noble Booksellers. Recyclebank proved that it is possible to increase participants' active involvement in environmentally friendly activities that ranged from switching to energy-saving light bulbs to buying more local produce. The Fun Theory incentivizes the development of games to encourage better behavior with a competition. Several of these efforts have focused on re-designing recycling receptacles as various arcade games, significantly increasing their use.

German Distributor featured in PV Mag online

Our German distributor Symström now has a web-shop and is selling Wattson Solar Plus as part of their product offering. 

Symström: Display leuchtet grün bei Überschuss

Source: PV Magazine DE, 20th August 2013

Das Leipziger Start-up Symström bietet in seinem Onlineshop ein neues Design-Display, das Wattson Solar Plus an. Es visualisiert sowohl die Stromerzeugung als auch den Verbrauch des Haushalts. Es leuchtet grün, wenn die Erzeugung den Verbrauch übersteigt und noch weitere Verbraucher zugeschaltet werden können. Im entgegengesetzten Fall schimmert es rot. Das Gerät arbeitet unabhängig von Wechselrichter und Stromzählern. Es werden stattdessen Stromzangen um die Stromphasen geklemmt, die die Energie messen. Ein Sender funkt die Daten dann an das Display. Auch die Leistung von Blockheizkraftwerk oder Windanlage könne damit erfasst werden, so Symström. Per USB-Kabel lassen sich die gesammelten Daten auch auf einen Computer überspielen.

News about Holmes & Wattson

Newsletter sent out on 9/08/2013 to all Holmes users.

Please click here to read the latest Holmes and Wattson news.


Wattson News
Dear Wattson and Holmes users,

We are proud to announce that our Holmes software has been redeveloped and is once again available for Mac OSX as well as Windows based computers. It is now easier to see how much you’re spending on electricity, when you use it most, and how to reduce what you use when you don’t need it.

As of September 2011, Wattson products are manufactured and distributed by Energeno Ltd, who purchased Wattson from DIY Kyoto. The new generation of products include Wattson Solar Plus, Wattson Classic and WattsonXL. The good news is that Wattsons purchased before September 2011 (Wattson01, Wattson Limited Edition, Wattson Solar) can also benefit from the increased capability of the display firmware and transmitter, see below. 

So download our news Holmes 2.0 software and take a look at our other new products and special offers while it’s installing.

Kind Regards,

The Energeno team.
