A1

and/

or

control

circuit

304

causes

wireless

transceiver

306

to

transmit

an

indication

that

motion

was

detected

by

the

sensor.

Accordingly,

control

circuits

of

the

controllers

receiving

the

indication

can

decide

whether

or

not

to

act

upon

the

indication

of

motion.

The

RF

signals

including

an

indication

of

motion

may

also

include

a

zone

identi?er

that

receiving

controllers

can

use

to

determine

if

the

signal

originated

from

their

zone

or

another

zone.

In

other

exemplary

embodiments,

controller

204

may

address

messages

to

particular

controllers

(e.g.,

the

addresses

of

neighbors

or

the

addresses

of

other

controllers

in

the zone).

Logic

module

314

may

further

be

con?gured

to

cause

the radio

frequency

transceiver

to

transmit

commands

to

other

radio

frequency

transceivers

coupled

to

other

?uo

rescent

lighting

?xtures.

For

example,

logic

module

314

and/

or

control

circuit

304

may

be

con?gured

to

interpret

a

signal

received

at

the radio

frequency

transceiver

as

indicating

that

motion

was

detected

by

another

device

in

the

zone.

In

an

exemplary

embodiment

of

the

lighting

?xture

controller,

some

will

be

con?gurable

as

relay

devices

and

when

so

con

?gured,

will

relay

any

commands

or

information

the

control

ler

receives

from

other

zone

controllers.

Controller

504

is

illustrated

to

be

con?gured

as

such

a

relay

device.

When

controller

504

receives

broadcast

500

indicating

motion

from

controller

261,

controller

504

relays

broadcast

500

via

trans

mission

502

to

other

zone

devices

(e.g.,

controller

506).

This

way,

an

event

such

as

motion

can be

propagated

to

each

of

the

lighting

?xtures

in

a

zone

without

network

traf?c

to

controller

261

and/or

without

necessitating

direct

control

of

the

lighting

?xtures

by

controller

261.

This

activity

may

be

con?gurable

(e.g.,

via a

GUI

provided

by

control

computer

252)

so

that

only

some

controllers

are

relays,

all

controllers

are

relays,

or

so

that

no

controllers

are

relays

and

only

devices

within

range

of

the

detecting

controller

act

on

its

broadcasts.

Further,

the

relay

or

rebroadcast

can be

address-based

or

more

similar

to

a

true

broadcast.

For

example,

in

an

address-based

relay,

the

controller

serving

as

a

relay

may

know

the

addresses

of

cer

tain

network

controllers

to

which

to

transmit

the

relayed

information.

In

another

example,

the

broadcast

may

be

gen

eral

and

not

addressed

to

any

particular

controller,

control

lers,

or

zone.

[0054]

To

implement

zone

control

activities,

each

control

ler

may

be

con?gured

to

store

a

lighting

zone

value

in

memory

(e.g.,

memory

316).

This value

may

be

used,

for

example,

to

determine

whether

another

device

sending

a

command

is

associated

with

the

lighting

zone

value

stored

in

memory.

For

example,

controller

271

may

include

a

lighting

zone

value

of

“II”

in

memory

and

controller

261

may

include

data

representative

of

controller

261’s

lighting

zone

value

(e.g.,

“I”)

with

its

transmission

indicating

that

motion

was

detected.

When

controller

271

receives

the

lighting

zone

value, controller

271

(e.g.,

a

control

circuit

or

logic

circuit

thereof)

may

compare

“I”

and

“II”

and

make

a

determination

that

controller

271

will

not

act

on

the

received

indication

of

motion

(i.e.,

controller

271

leaves

its

relays

off

while

all

of

the

controllers

in

zone

I

switch

their

relays

on).

[0055]

Referring

now

to

FIG.

6,

a

?ow

chart

ofa

process

600

for

controlling

multiple

lighting

?xtures

in

a

zone

based

on

sensor

input

is

shown,

according

to

an

exemplary

embodi

ment.

Process

600

is

shown

to

include

receiving

signals

from

a

sensor

(e.g.,

sensor

210)

coupled

to

a

?rst

controller

for

a

?rst

zone

(step

602).

Once

received,

circuitry

of

the

?rst

controller

can

determine

whether

the

received

signals

repre

sent

an

event

that

should

be

acted

upon

(e.g.,

by

changing

lighting

states,

etc.)

in

the

?rst

zone

(step

604).

Process

600

is

Apr.

10,

2014

further

shown

to

include

using

circuitry

of

the

?rst

controller

to

transmit

a

command

and/

or

an

indication

of

the

event

with

a

?rst

zone

identi?er

(step

606).

The

transmission

is

received

by

a

controller

in

a

second

zone.

Circuitry

of

the

controller

in

the

second

zone

determines

that

the

transmission

is

for

another

zone

and

does

not

act

on

the

received transmission

(step

608).

The

transmission

may

also

be

received

by

a

second

controller

for

the

?rst

zone

(step

610).

Circuitry

of

the

second

controller

for

the

?rst

zone

inspects

the

received transmission

and

acts

on

the

information

of

the

transmission

when

the

controller

discovers

that

its

stored

zone

identi?er

matches

the

received

zone

identi?er

(step

612).

The

second

controller

for

the

?rst

zone

may

also

be

con?gured

as

a

relay

node

and

to

retransmit

the

received

command

or

indication

to

other

?rst

zone

controllers

(e.g.,

controller

506).

[0056]

FIG.
