This month’s column has news of new energy-saving incentives for smart meter users, the
ORA Funky Cat BEV finally launches, some of Logitech’s mice are considered and there’s
more space program news.
A
s winter approaches, with
another potential energy
crunch looming, news
recently leaked out in Britain that
some consumers would again be
offered cash to reduce their energy
consumption during periods when the
energy supply was under pressure.
It’s now four years ago that I wrote
about the country’s faltering smartmeter programme which, on the face
of it, was being marketed as a benign
scheme to help users monitor energy
consumption and save money (Net
Work, December 2019). Back then, I
wrote that ‘ultimately, [smart meters]
will change the way we manage our
power consumption – and pay for
it – for ever.’ I think the same still
holds true today.
In Great Britain, the National Grid
ESO (Electricity System Operator) is
responsible for delivering electricity to
British homes and businesses: they own
the wires and pylons, while separate
electricity suppliers buy electricity
from the power generators and resell
it to end-users, as the National Grid
explains at: www.nationalgrideso.com
In Q1 23, the renewable sector’s share
of total generation reached 47.8%,
setting a new record. A network of
interconnectors also enables gas and
electricity to be exported or imported
between the UK and other countries,

supplies across the country. (Image: National Grid)
A recent summary on energy trends
by the UK Department for Energy Security and Net Zero showed that the
UK actually exported 41% more gas
compared with a year ago, to help prop
up mainland Europe’s energy shortfall.
Furthermore, the UK has the second
largest Liquefied Natural Gas (LNG)
regasification network in the whole
of Europe, the department says, allowing the UK to support mainland
Europe’s efforts to reduce its dependence on Russian gas.
The transmission of electricity is
managed at the National Grid ESO
Electricity National Control Centre
(ENCC). The huge problem we face is
of course the lack of spare capacity,
especially if a severe winter threatens.
The idea behind Demand-Side Response (DSR) is to iron out the peaks
and troughs by balancing the available

energy with customer demand. Smart
meters will enable demand for energy
to be ‘shaped’ and, if necessary, consumers could be encouraged to turn
down the lights at peak times by, for
example, offering them cash rebates.
Limited trials were held early this
year when the National Grid implemented its so-called Demand Flexibility
Service (DFS) for the very first time,
which gave modest rebates to some
users who reduced their demand. A
further 12 DFS tests will be held this
winter, says the National Grid, starting
in November 2023 through to March
2024. This will help to show whether the scheme is commercially viable,
noting that participants with a smart
meter need to sign up for DFS through
their own supplier. (As more evidence
of the direction of travel, there really
is such a thing as the 2023 Net Zero
‘Behaviour Change Campaign of the
Year’ and National Grid ESO’s Demand
Flexibility Service is shortlisted for an
industry award.)
In theory, smart meter customers
could also be switched to other tariffs
or pricier pre-payment packages, or ultimately be disconnected altogether, all
by remote control. Since a lot of raw
data is already out there, it’s not inconceivable that users could eventually
be charged extra for using power on
calm and cloudy winter days if wind
and solar energy were in short supply,
as another incentive to turn down the
heating. Meanwhile, my own energy
supplier, EDF, has tried contacting me
more than 100 times by phone, text and
mail to book a smart meter installation
but I’m resisting for as long as I still
have a choice.
Despite having a mixed reputation,
many users are very happy with their
smart meter and find them useful
in managing their energy accounts,
but there are numerous problems
with In-Home Displays not working
properly and the UK Citizen’s Advice
Bureau has now devoted a useful section to dealing with IHD problems,

Trading places
To a layman, there may seem to be a
lot of horse-trading going on somewhere if suppliers claim they offer
‘green energy’ or ‘100% renewable’
energy to their customers. After all,
Britain’s electricity comes from various sources (power stations, solar,
wind and so on) which all feed into
the same National Grid. As far as end
users are concerned, it’s just electricity
coming out of the wall socket, whether it’s from a nuclear power station or
a wind farm somewhere in the North
Sea. So, if it’s all the same stuff, how
can we know if our ‘green’ electricity
actually comes from renewables and
not, say, from a nuclear power station
in France instead?
Energy supplier E.ON is up front
about this, stating that its renewables
tariff is ‘Electricity backed by 100%
renewable sources, E.ON’s renewable
generation assets ... and the purchase of
renewable electricity certificates. The
electricity supplied to your home or
business comes from the National Grid.’
The subject of electricity certificates is a complex paper exercise and
it’s managed through the voluntary
adoption of what are called ‘Energy
Attribute Certificates’ (EACs). Trying
to unpick how they work makes for
some heavy reading, but essentially it
boils down to having a system of verifying and certifying the output from
energy producers in terms of where
the MWh units of energy actually
come from. In effect, this electricity
generation data is then ‘booked’ or
totalled up and it then goes into a virtual melting pot. EACs are described
as ‘tradable digital certificates’ that
contain factual details of how every

will face fierce competition from rival EV brands.

MWh of energy was generated. They
can then be ‘claimed’ or traded, regardless of where the underlying
commodity (electricity in this case)
originally came from.
Suppliers can dip into this finite pot
to buy or trade certificates, either as
one-offs or under contract. Using this
‘book and claim’ method, the industry gains a tight understanding of how
much energy is produced, and of what
type, and rigid controls help ensure
that electricity sources can’t therefore
be ‘over-sold’. The same system of certificates extends to carbon capture and
low-carbon hydrogen distribution. I
can’t say how rigorous or robust the
scheme actually is in practice, but
in-depth details of how the system
of EACs operates are provided by the
non-profit International REC Standard
body at: www.irecstandard.org
A cool and Funky Cat
Adverts have started appearing online
for the ORA Funky Cat, a cute-looking
battery electric vehicle (BEV) produced
in China by Great Wall Motor (first described in Net Work, January 2022). It’s
known locally as the Haomao (Mandarin for ‘Good Cat’). The BEV scored an
impressive 5 star rating in Euro NCAPs
safety tests and its makers hope that its
attractive retro styling and equipment
levels will win over many buyers. Prices
now start at £32,000 which, like most
BEVs, is a very tall order for many hardstretched drivers today, but finance and
PCP are also offered. You can take a
look at: https://gwmora.co.uk
Car sales are 20% up on last year,
driven mostly by fleet sales, as the
sector emerges from the pandemic and
problems with semiconductor shortages finally recede. While the sanguine
motoring press claims that BEV sales
are up by 72.3%, that’s only comparing August 2023 (17,200 units) sales
with the same time last year (10,000).
A quick glance at the latest SMMT statistics shows that, year to date, just one
in six cars (16.4%) sold were BEVs.
Petrol cars remain the biggest sellers,
with 41.6% of the market, leaving 42%
for hybrids of all types, plus diesels,
remembering that hybrid EVs still have
engines in them!
The ORA will face fierce competition
from a revitalised MG Cars with BYD
(Build Your Dreams – see Net Work,
May 2023) introducing soon its next
EV, the well-regarded BYD Seal. China’s SAIC, the owners of MG Cars, is
contemplating building its first factory
in Europe and also expects to launch

From RAGS to riches
The 20-year old Logitech MX1000 is
reckoned by the author to be one of the
best full-size cordless mice ever made. Its
microswitches, batteries and PTFE skids
are repairable.
With stock levels rising and availability improving, used car prices
have fallen in the last five consecutive
months, says Car Dealer magazine, but
traders are still being very picky about
stocking electric vehicles. Meantime,
TV screens continue to pump out adverts for space-age BEVs that it seems
five out of six car buyers can’t afford
or don’t want to purchase.
Totally IlLogitech
Last month, I mentioned how some of
Logitech’s early webcams utilised AI
image-processing software that enabled
the camera to ‘follow’ a moving subject. During the Covid lockdown, many
staff chose (or were ordered) to work
from home, which, along with semiconductor shortages, sent the price of
webcams, laptops and gaming peripherals soaring. Supplies often dried up,
and some readers might recall how I
tried sourcing a Logitech C280 webcam
for myself during the pandemic crisis.
After I finally pinned one down, my
triumph was short-lived as the highly
prized (and over-priced) peripheral disappeared mysteriously while en route
from Amazon in Italy.
Logitech clearly made the most of the
lockdown period: accounts filed in the
USA show how Logitech’s gross profits
more than doubled from $1.1bn in the
year ended 31 March 2020 to $2.3bn
in 2021, and net income before taxes
more than tripled in the same period.
Since then, sales of all product
ranges have fallen across the board,
with Logitech reporting that webcam
sales have declined by 44% and net
income has plunged by 60%. Perhaps
hard-stretched consumers are making
do with what they’ve got in, or the
latest products offer few benefits and
aren’t worth the investment in time
and money. Logitech’s Chair and CEO
Bracken Darrell, the name credited with
transforming Logitech’s fortunes in the

Many seasoned PC users will have
used Logitech keyboards and mice at
one time or other and, in my experience, one of the best computer mice
ever made was the Logitech MX1000
Laser launched about 20 years ago.
This cordless mouse had a meaty, ergonomic form factor that fitted one’s
(right) hand perfectly. Sought-after new
old stock (NOS) models can fetch £200
($250) or more on eBay today.
Instead of throwing cash at expensive replacements, I service or repair
my MX1000 every few years. The
grippy, rubberised finish eventually
wears off or goes sticky, something
easily cleaned off with isopropanol.
Eventually, switch-bounce causes
troublesome double-clicking, but the
Omron microswitches are repairable
with some careful de-soldering. Not
that I obsess about it, but the battery and stick-on PTFE feet (skates or
skids) can all be sourced from eBay or
AliExpress and I’ll sometimes buy
tidy used examples for spares.
One of Logitech’s legacies is their
annoying habit of giving items a model
number (M/N) as well as a user-friendly name, which makes searching
for FAQs, tech support or drivers
frustrating at times. My ‘MX™1000
Laser Mouse’, as they call it, is also
known as an ‘M-RAG97’ but searching
Logitech’s website for either phrase
returned no results.
Eventually, I scrolled through the
‘Support for Individuals’ section to
find the elusive mouse and – more
importantly – the legacy Setpoint
driver software that’s needed to get
the best out of it. However, I still hit
a brick wall as several web pages were
404, and no software was available
anyway – one reason why it’s a good
idea to back up old drivers or keep old
product CD ROMs. Despite all these
setbacks, my mouse is working almost
as well as the day it was bought, running perfectly on Windows 98 through
to Windows 10.
Pointing left
Not that I’m against progress: a few
months earlier, after checking out
Logitech’s latest mouse range for a
Windows PC that was going abroad,
I chose a Logitech Signature M650 L
‘full size wireless mouse’ which seemed
the best mid-priced choice for larger
(hence the ‘L’ suffix) hands. A version
designed for left-handed users is also
offered, named the ‘M650 L LEFT’.
Logitech’s Signature M650 L wireless
mouse is described as a ‘large size’
mouse for large hands. It’s also available
as a left-handed version. USB ‘Bolt’
adapter also shown; the mouse can also
use Bluetooth.
I found this latest cordless mouse was
smaller, more lightweight and a lot more
skittish than my old MX1000, but it also
demonstrated the current state of the
art in cordless mice design: instead of
using a docking station to recharge an
NiMH battery, the mouse holds a single
AA battery giving up to 20 months’
operation; I use a (non-rechargeable)
Energiser Ultimate or VARTA Ultra
Lithium AA cell, which I expect will
give several years of service.
The connectivity side is steeped in
Logitech’s trendy marketing jargon.
Being cordless, a tiny USB receiver
called the ‘Logi Bolt’ is supplied for
PC use, but the same mouse can also
use Bluetooth to connect to, say, a
laptop or tablet. In this mode, Logitech
says it’s compatible with Windows
10+, macOS 10.15+, Linux, ChromeOS, iPadOS 13.4+, Android 5.0+ and
Evo Laptops.
For PC users, their ‘Logi’ software is
installed, but instead of good old-fashioned drivers, users are offered ‘Logi
Options+’ which it describes as the
‘next gen app for your mice and keyboards’. It seemed to install without a
hitch, but I strongly dislike the sprawling software which takes up far too
much unnecessary white space on
screen and displays a bad case of designer-itis. Fortunately, you won’t need
to use it very often.
After some tweaking and localisation
ready for its new home overseas, the
PC was ready for shipping, complete
with its new mouse. A few weeks later,
I received an urgent call for help from
the PC’s new owner – the Logitech
mouse had suddenly stopped working and she urgently needed to print
off a business document. An ordinary
wired USB mouse would help at such
times, but one wasn’t available.
While searching desperately online
for a user manual and FAQs, I found

old interface, which I very much prefer. You can download

Antex Electronics, the UK-based manufacturer best known
for its soldering equipment, has launched a hot tool designed for reworking and trimming 3D-printed objects.

TeamViewer is among the best remote networking programs
and it’s free for personal use.
Logitech’s sprawling, over-designed website exasperating:
their diagram of mouse buttons and features had no key to
identify which is which, so I had to try describing to the
user over the phone which buttons to try pressing next. The
Logi software displayed a forlorn ‘Fix Device’ and a trashcan symbol, which would presumably delete the mouse
altogether. I finally gave up when Logitech’s online support
suggested the user opens and checks the Windows Device
Manager for errors: how can you, if the mouse doesn’t work?
(The answer is that you can, by typing Winkey + R to open
a Run box, type devmgmt.msc and hit Enter – not that it
would have helped anyway.)
With the clock ticking away, I had one last stab at fixing the
problem: I suggested unplugging and re-connecting the tiny
USB ‘Bolt’ receiver again, on the back of the PC. She followed
the directions and, lo and behold, the mouse immediately
sprang into life again! The documents were then printed off
just in the nick of time. I suggested she also goes and buys a
cheap spare mouse from the supermarket, just in case.
At other times, using remote access would allow me to
log in and operate the PC as though I was sat in front of it,

remotely many times this way. Generously, TeamViewer is

ISRO’s Pragyan Rover snaps the Vikram lander at the south pole of the Moon (ISRO/X)
In August, the Indian Space Research Organisation (ISRO) saw its
Chandrayaan-3 spacecraft (translated as ‘Moon Vehicle 3’) complete a
flawless historic mission. This ambitious project placed a lunar lander
at the Moon’s south pole, making
India only the fourth country to land
on the Moon and the first country ever to explore the south pole.
The moon lander, named Vikram
after Vikram Sarabhai, the ISRO’s
founder, carried the Pragyan Rover,

At the same time, Russia’s Luna-25
mission, also aiming at the south pole in
August, was unfortunately lost during its
final approach. Japan has just launched
its own moon mission, the ‘Moon Sniper’
which should land next February. They
hope to place the SLIM (Smart Lander
for Investigating Moon) vehicle within
100m of the intended target.
