4 Welcome
Congratulations on your purchase of the
Powersoft DEVA.
DEVA is a lightweight and compact multifunctional
device that implements bi-directional wireless
communication, audio messaging and video
capturing.
Once congured, DEVA is a self-sufcient device
equipped with sensors – microphone, presence
detector, temperature and pressure probes – and
accessories (e.g. LED light, camera, etc.) that make
it capable to interact with the environment through
the built in loudspeaker and audio/video capturing
feature.
DEVA has been designed to be independent from
any existing infrastructure, without the need for
wiring and with virtually zero installation costs. DEVA
uses green technologies: its highly efcient design
limits power consumption allowing uninterrupted
use powered by the internal rechargeable battery;
a latest generation solar panel can quickly recharge
the battery even in low light conditions.
DEVA's enclosure is weather-resistant IP65,
an ideal solution for outdoor applications from
background music to paging, in combination with
video and/or audio surveillance.
DEVA provides bi-directional messaging and
ambient control; DEVA allows conguration and
monitoring via WiFi as well as wired Ethernet
connections to tablets, pc and mobile phones.
Remote control is available via GSM/GPRS/UMTS.
DEVA is a self-sufcient fully congurable
networking unit that can be installed anywhere!
5 DEVA in a glance
DEVA is capable to perform tasks and react
to certain events on the basis of a scheduled
program and an event list. The interaction with the
environment triggers a set of actions spanning from
sound playback to taking pictures. In systems with
more than one DEVA, scheduled actions – such as
playing audio les – are synchronized by means of
the DEVA System Manager, the control pannel that
provides full management of DEVA, installed into
the Powersoft DEVA Director – PDD.
The DEVA System Manager allows you to stream
live announcements and audio les to all selected
DEVA as well as set:
ftime schedule for actions:
fLight – switch the light on or off.
fPlay message – play a le in the default
audio les list.
fPlay from Audio library – play a le from
the audio library.
fPlay playlist – execute a playlist of audio
les.
fTake Photo – shoot a single ambient photo
or choose to shoot a number of pictures
delayed by the selected time.

7 Actions and Players
7.1 Actions
Depending on the version, DEVA performs a set
of dened actions:
fPlay audio
fSwitch the light
fTake photo
fRecord audio
fNotify with a message (sms/email)
7.2 Players
DEVA provides four audio players that manage
respectively:
1. live stream of audio
2. playback of single audio le
3. playback FM radio
4. playlist of audio les
The four players can be active at the same time,
but only two of them will play simultaneously,
according to their priority:
live stream > single le > FM radio > playlist
hiGh priorit y > low priority
The four audio players are layered on the basis of
the playback priority:
fthe playback of a live streaming (either an audio
le or from the microphone) has the priority on
the playback of an audio le from the library;
fthe playback of a single audio le has the priority
on the playback of the FM radio;
fthe playback of an FM radio has the priority on
the playback of a playlist.
The player with the lower priority plays in
background (i.e. lower in volume) when a high
priority player starts playing.
NOTE: The default behaviour can be overridden
by changing the volume level during the playback.
Each player provides independent volume control.
The playback volume of each player is a fracion
(expressed in percentage) of the master volume.

Getting Started |13
Getting Started
Before proceeding to the placement of the
DEVA on site (ref. Chapter “32 Mounting kits”),
we recommend to setup the device by following
the assembling and initialization procedure “on the
desk”.
The initialization phase can involve the manual
setup of the device; once properly initialized and
congured, DEVA has been designed to be self-
operating and remotely managed.
The initialization workow includes:
1. battery assembly on the DEVA;
2. SIM assembly;
3. DEVA start-up;
4. initialization of the connections (networking);
We suggest to follows the instruction on this
manual in order to properly setup the DEVA.
12 Battery assembly
DEVA comes with a battery pack already located
into its battery compartment (ref. FIGURE 6). The
battery pack shall be properly connected before
operating.
1. Open the battery compartment.
2. Verify that the battery presents no failures.
3. Plug the battery:
fconnect the red + (positive) faston to the
battery’s positive plug (beware the 4 A fuse);
fconnect the black – (negative) faston to the
battery’s negative plug.
4. Place the battery temperature probe wherever
into the battery compartment, far from the
electric plugs.
5. Reposition the compartment cover and tightly
screw the six hex screws.
In order to ensure full operability,
Powersoft recommends to fully charge the battery
before starting the initialization procedure.
The battery charge can be achieved by means of
either:
fan external power supply capable to deliver 20
VDC and up to 3 Amax (e.g. solar panel, DC power
supply unit, etc.) connected to the Phoenix MC
1,5/ 2-ST-3,81 (ref. FIGURE 1 #15);
fa 16 VDC, 1 Amax power supply plugged to the
5.5 mm coaxial plug (ref. FIGURE 1 #8);
fa 48 VDC PoE via the Ethernet connection (ref.
FIGURE 1 #11).

14 |DEVA |User Guide
14 Start-up
Once the battery has been properly assembled
(ref. Chapter “12 Battery assembly”), the DEVA can
be switched on. By default, DEVA starts-up when
any external power supply (i.e. solar panel, DC
power supply unit, PoE) is plugged in.
When the DEVA is connected to an external
power supply, the system starts charging the internal
battery: when the power supply delivers more than
12 VDC the DEVA starts-up automatically.
In approximatively 90 seconds the operating
system completes the bootstrap procedure and
makes the device ready to work. During the
bootstrap you can hear a long beep coming from
the DEVA: the presence of this signal means that the
system is booting.
14.1 DEVA start-up without external power supply
In case no power supply is available and DEVA
is off, you can switch on the DEVA by means of the
ON/OFF button (ref. FIGURE 9).
1. Push on the ON/OFF button and keep it
pressed:
2. the green LED switch solid on;
3. still keep the ON/OFF button pressed until the
green LED start blinking (5 s approximatively);
4. release the ON/OFF push button: the
bootstrap procedure takes place and a long
beep is emitted.
Be aware that the start-up procedure without
power supply will not take place if the battery
charge is below 12 VDC.
13 SIM card assembly
DEVA supports GSM and GPRS communication
protocols via a standard SIM – Subscriber Identity
Module – card*. Follows these instructions in order
to install the SIM card.
1. Unlock the SIM by disabling the PIN request
at the switch on: this can be mabe easily by
inserting the SIM into a mobile phone and
disabling the PIN request.
2. Access the dashboard compartment and gently
slide and tilt the SIM card tray (ref. FIGURE 7).
3. Insert the SIM card into the slot a reposition
the tray.
* Not included in the package. Ask to your local IT providers.
The GPRS communication features shall be
activated and managed through the DEVA System
Manager (ref. Chapter “27.2 Setting DEVA network
parameters”)

16 USB MP3 playback
The playback from the USB override any audio
playing on the DEVA: in order to start the playback
of the les from a USB device you have to press
simultaneously the SEEK+ and SEEK– push button
on the DEVA dashboard.
The actual scheduled action does not stop: while
the USB audio content is playing, any scheduled
playlist runs to the 30% of its preset volume.
In order to allow DEVA to reproduce the MP3
les from the USB, the audio les shall be stored
in the AudioFiles folder in the root of the USB
storage device.
DEVA can play only MP3 les, no other le
formats are allowed. Playback of the audio les is
looped in alphabetical order. The commands to
manage the playback from USB are located on the
DEVA dashboard (ref. FIGURE 10):

17 Networking
DEVA can be set as a stand alone device or
integrated into any existing wired, wireless or mixed
network. A proper network setup includes:
fPowersoft DEVA Director – PDD. The PDD
is a personal computer implementing a custom
GNU/Linux based operating system: the PDD
provides a client-server environment that
allows the user to easily manage the network
of DEVA.
Both the DEVA and the PDD must be
connected to the same network; this means
that all devices have to be either hosted by the
same Wi-Fi access point or wired to the same
thernet switch and sharing the same subnet and
IP range.
fDHCP server (often already implemented into
routers and acces point). Both the DEVA and
the PDD are set to dynamic IP addressing.
fEthernet switching (often already implemented
into routers and acces point) with a proper
number of ports for wired connectivity;
fWi-Fi access point for wireless connectivity;
fOne or more DEVA.
In the following pictures we suggest some network
topologies oriented to a domestic environment,
where the router/AP implements both the DHCP
server and the Ethernet switch.
17.1 DEVA in a wireless LAN
DEVA and the PDD are connected wireless to
the access point. Any further client on the wireless
network can manage the network of DEVA: in order
for the client to manage a DEVA it must to connect
to the PDD.
17.1.1 Mesh network
DEVA can connect to a mesh network, so that to
cooperate in the distribution of data in the network.
In a mesh network topology, each DEVA is a node
that relays data on the network, providing multiple
connections to other DEVA in the mesh.

Getting Started |17
18 Initialization
The initialization is performed by means of the
PDD – Powersoft DEVA Director –, by connecting
the DEVA to the local network through a wired or
wireless connection.
You may need the following equipment:
fPowersoft DEVA Director – PDD;
fDHCP ser ver or a router with DHCP capability;
fswitch with a proper number of ports for wired
connections;
faccess point – AP – for wireless operating.
18.1 Initialization in a wireless LAN
By default DEVA tries to connect to a Wi-Fi
network whose SSID is set to POWERSOFT.
In order to perform the initialization procedure
we recommend to set your AP as follow.
1. Connect the PDD and the AP to the same
LAN (wired or wireless): ensure that they
share the same IP range.
2. Log-in the PDD and launch the browser.
3. Point your browser to the IP address of the
access point and enter its control panel.
4. Modify the SSID of the access point to
“POWERSOFT” and password “powersoft”.
Save and reboot the access point. While
rebooting you will loose the connection: after
some second, refresh the page on the browser
and reconnect to the AP.
5. By default DEVA looks for the POWERSOFT
Wi-Fi network. Through the AP control panel
you should monitor all connected devices.
17.2 DEVA in a wired LAN
Both the DEVA and the PDD must be connected
to the switch. The DHCP on board of the router
assign a unique IP address to each DEVA and PDD in
order for them to belong to the same subnet.
Through the PDD it is possible to manage the
network of DEVA, set schedules and events, monitor
the performance and launch an announcement on
specied DEVA.
Refer to Chapter “27 Advanced network
settings” for more information on how to congure
the DEVA network parameters and the PDD in
order to match your network environment.

DHCP + switch
PDD

18 |DEVA |User Guide
18.2 Initialization in a wired LAN
In order to perform the initialization procedure
in a wired network environment, all devices have to
be connected to a DHCP server (possibly through
an Ethernet switch) in order to receive unique IP
addresses within the same subnet.
1. Connect the PDD and the DHCP server to
the same network: ensure that they share
the same IP range, i.e. the PDD receives its IP
address from the local DHCP server.
2. Connect each DEVA to the same network of
your PDD and switch them on (ref. Chapter
“14 Start-up”).
3. Now follow the same procedure described in
Chapter “18.1 Initialization in a wireless LAN”
starting from point 6.
6. Open the DEVA System Manager:
on the browser address-bar write
http://localhost:8080
7. Log in the DEVA System Manager: the
administrator account has the following default
credentials:
username: admin
password: admin
Once logged in, the DEVA System Manager
shows the latest saved network conguration:
since you are going to initialize your network, no
one DEVA is listed.
8. Click the button Discovery on the Toolbar: the
DEVA System Manager will start seeking and
connecting new devices on the network.
Now you can start setting DEVA.

Almost any settings on DEVA are performed by
means of the DEVA system Manager – DSM. The
audio playback from a USB key and the hard-reset
of the system are available just through the DEVA
dashboard.
The DSM offers a user friendly interface for
setting time schedules for actions, event triggers and
full access to DEVA features (ref. Chapter “5 DEVA
in a glance”).
19 Setting users permissions
By assign roles to registered users, it is possible
to control what users can do through the DEVA
System Manager.
Each registered user belongs to just one role.
