This document provides a summary of a talk on smart homes at scale given in three parts: 1. A smart energy report discussing a data analytics engine that provides insights into household energy usage patterns using various models informed by inputs like temperature, location, and appliance usage. 2. Standards and openness, emphasizing the need for open standards as markets mature to allow customer choice and ecosystem partnerships through projects like HyperCat, which makes services machine-browsable. 3. A home energy update noting that households now own far more electronic devices and appliances than in the past, and that smart meters are being rolled out widely in the next two years.

– Built
upon
several

• Models
informed
by

– Temperature,

Type
of
appliances
and
usage
– and
others
…
• Models
include:
– Space
HeaCng,
Hot
water,
Cooking,
LighCng,
Appliances,
Occupancy
– and
others
…

9. Standards
and
Openness
• As
a
market
matures,
there
is
a
sudden
“flip”
– From
“no-­‐one
to
be
open
to”
– To
“openness
is
essenCal”
• Can’t
do
it
all,
need
ecosystem
partners
• Customers
want
to
have
choices

11. Everyone’s
system
architecture

13. You
need
data
from
several
services

14. All
services
use
open
standards
https:

15. But
each
is
organised
differently
/customers/building/room/temperature
/users/hubs/devices/
/localauthority/street/post

16. So
for
each
service
you
have
to…
• Read
the
documentaCon
• Write
code
specific
to
that
service

17. Everyone
wants
an
ecosystem
If
each
applicaCon
is
specific
to
each
service
we
call
it
“verCcal-­‐integraCon”.
To
grow,
we
need
to
go
“horizontal”
and
build
an
ecosystem
where
all
applicaCons
work
with
all
services

18. …but
Humans
Don’t
Scale
But
adapCng
10
ApplicaCons
x
10
services
=
100
pieces
of
code
to
write
(and
imagine
1,000,000
ApplicaCons…)

19. Problem:
Services
not
machine-­‐browsable
An
applicaCon
cannot
automaCcally
discover
a
new
service’s
resources
…
so
a
human
has
to
write
code
every
Cme
to
enable
it
to
do
that.
I
don’t
know
where
to
start

services

What

21. HyperCat:
Easier
life
for
everyone
• Developers
– More
data,
quicker
• Service
and
Data
providers
– More
customers
• End-­‐customers
– More
choice
• Ecosystems
and
markets
– Removes
barriers

22. HyperCat
is
not
a
panacea
• ApplicaCons
and
Services
sCll
have
to
agree
on
high
level
semanCcs
– i.e.
if
a
service
provides
temperatures
in
°C
then
the
applicaCon
needs
to
understand
°C
• What
HyperCat
does
is
enable
an
applicaCon
to
find
those
things
that
it
does
understand,
in
any
service
– e.g.
“show
me
all
the
resources
which
are
in
°C”

23. Work
in
progress…
All
the
things
we
kicked
out
of
scope!
• Data

(SenML)
• Ontologies
(general,
and

more

• RegistraCon
• Standard

• Key

• MoneCsaCon
models

24. From

same
thing.

25. “Open”
Not
(necessarily):
• Free
• Public
Means:
• My
service
works
with
your
service
• We
can
swap
providers
without
a
lot
of
effort
• Requires
less
trust

26. We
may
think
we’re
“the”
service

27. But
we’re
just
another
node
in
the
graph

• Household

• Because

• SCll
