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.

Energeno introduces Opti-Range of products

Source: Solar Power Portal

Energeno, a developer and supplier of energy monitoring systems including the Wattson Solar Plus energy monitor, has launched its new Opti-Range of products at Solar Power UK 2012 which is being held this week in Birmingham at the NEC.

Designed for solar PV households, the new range comprises the Optimmersion and the Optiplug. Optimmersion is an intelligent controller which, when added to a solar power installation, automatically diverts free electricity to the immersion heater when the solar PV has produced surplus power. Installed between the immersion tank and the consumer unit, it supplies variable power for hot water depending upon the excess energy being generated. Typical savings are around £55 per year for a gas boiler and £80 for electrically-heated water.

Energeno has introduced its Optimmersion and Optiplug products at Solar Power UK 2012.

Optiplug is a smart socket which collates data on how much energy appliances around the home are using and switches power to them only when enough surplus energy is available to run them.

Both technologies ensure that householders have greater control over their energy use when they are not at home and ensure they are not paying for expensive electricity bought in on the day from their energy provider. This also means that in the majority of cases they are not affecting the revenue they generate from the Feed-in-Tariff.

The two devices, which work through intelligent RF sensors and are linked to clever switches that calculate the excess electricity being generated, are part of a larger suite of home automation products being developed by Energeno to access free energy produced by solar PV panels. Other products in the range will be launched later in the year and during 2013.

“Thousands of people who have had solar PV fitted have become armchair experts on when to use the free electricity they are generating.” said Mark Elliott, Director at Energeno.

“However, people also have jobs to go to and cannot always be at home to make the calculations to access the free electricity. This is where smart technology comes to the fore because the devices make the calculations for you whether you are home or away,” he added.

Thank you for visiting us at Solar Power UK

It was great to see everyone at the show and to introduce our new range of products.

Here are a few snaps taken at the show of the Energeno team in action.

When Wattson glows green - shown here by Richard W - it diverts all the spare electricity to the immersion heater, thanks to the clever proportional controller- held up by Richard S.

Energeno now offering PV Sales Kit

Energeno have recognised the real need for installers to educate homeowners on the concept of PV and how they can benefit from it, allowing them to sell more PV kits in this very difficult market.

A live sales demonstration with the right tools helps potential customers mentally picture what having Solar PV in their own home would be like, helping them make the decision to buy it.

We have therefore created the Wattson PV Sales Kit, a compact and standalone sales tool that installers can take to the homes of potential customers to increase their chances of making a sale.

The Wattson PV Sales Kit contains everything needed to give a demo anywhere, anytime and installers can very easily help their potential customers see how using energy generated through Solar PV will:

  • Generate them money through the Feed-in-Tariff.
  • Allow them to make additional savings
  • Reduce their payback time

Ana small

The Wattson PV Sales Kit includes a simple box with buttons controlling virtual appliances and a virtual Solar PV array connected to a Wattson Solar Plus display. Switching appliances or the array on or off causes the Wattson display to react in exactly the same way as it does when connected to a real home. When the Wattson glows green it shows them how much spare electricity they could be using but are currently losing to the grid. The kit also includes PV Sales tips to get the message across effectively and material to leave at the customers about Wattson Solar Plus.

If you are interested in ordering the Wattson PV Sales Kit for your installers, please contact your usual point of sale, or sales@energeno.com.
