1. About Lighting Automation
This section gives you a brief introduction to the Lighting Automation
segment. Light Automation means to monitor, control and automate all the
appliances which are operated using the traditional switch. Using Smart Node
Lighting Automation modules, one can have access to all the lights, fans, device
connected through the plug (AC, TV, phone charger and many more) from its
Smart Node mobile application as well as supported third-party integrations like
Alexa, Google Home and many more.
With Smart Node Lighting Automation installed, you can enjoy a multitude
of features such as controlling appliances through mobile application, voice
(such as Alexa, Google Home), mood-based scene settings, appliance
scheduling and Geo-location based control. Smart Node has 6 different
modules in Lighting segment: 8.1, 8.0, 4.1, 4.0, 2NL and 2HL.

2. Smart Node Lighting Module 2NL
Smart Node Lighting module 2NL can automate two different types of load.
Using LA-2NL, you can turn on/off, schedule and lock the appliances connected
to it. This module has a support of two regular loads. The load combination in a
single module is a major uniqueness of Smart Node. The combination of the
load possible with 2NL is described in the further sections.
Here, in 2NL model:
2 indicates a total of 2 load support
NL indicates both load are normal load
Note: Fan/dimmable light can be connected to 2NL but it cannot be regulated
(speed/light intensity)using Smart Node application
2.1 Mode of operations
The loads connected to LA-2NL module can be operated by four different means
at a time.
1) Traditional Switch/Smart Node Touch Interface
When traditional switches are connected with LA-2NL, then the loads
connected with it can be operated with the manual switches as well as fan
regulator.
When Smart Node Touch Interface is connected with LA-2NL, then the
loads can be turned on/off using the Touch Interface. The main advantage of
installing Touch Interface is that even if loads are operated using the application
then live reflection indicates on the touch interface. The Smart Node Touch
Interface also adds elegant beauty to the interior of any house.

2) Smart Node application
All the loads connected to LA-2NL can be operated using Smart Node
application in Android as well as iOS phones. The application is available free
of cost in the App Store as well as the Play Store. The loads can be operated
from anywhere in the world provided internet is available on both sides. If the
device and the phone are connected to the same Wi-Fi, then loads can be
operated even without internet. Some of the features present in the Smart Node
application are explained in short below:
•Scene
Scenes for the lighting module can be created in Smart Node
application. On a single click, multiple operations can be performed.
•Schedule
We can individually set schedule to each load to turn on/off at any
particular time at any particular days. We can also set the schedule in
repeat mode or once mode. We can even dim the load using the
schedule. A total of simultaneous 25 schedules can be set a time in one
Lighting device. All schedules are executed independently of the
internet.
•Child Lock
We can lock the physical access of the switch in on/off mode using
Smart Node application. By locking the switch, the load will not be
operable by the connected mechanical switch or Smart Node Touch
Switch.
•Power State
We have a feature names Power state. When the feature is turned on,
the state of the loads, as well as dimming, are saved on power-cut. The
loads that were already on, will start as on and vice-versa.
When the feature is turned off, the state of the loads, as well as
dimming, are saved on power-cut and all the loads will start in off
state.

•Geo-Fencing
Using Geo-Fencing feature, automatic scenes can be executed as per
our entering or exiting a specific location.
•Live Notification
A user gets instantly notified if there is any change in the appliance's state
or when a schedule gets executed.
3) Voice control device
All the loads connected to LA-2NL can be voice-controlled using voice
enabling device like Amazon Alexa and Google Home. The loads can be turned
on/off using our voice.
In Android phone, if the email id used in the Play store is same as in
Google Home, then one can control the load directly through Google Assistant.
No need to have a Google speaker for that.
4) Third-Party Applications
Smart Node products are compatible with third-party applications like
Smart Things.

3. Basic Hardware explanation
This section covers explanation about different types of load in 2NL. The
front view of 2NL is shown below:
Here Ph indicates Phase (Live wire) input, N indicates Neutral input and HP
indicates Heavy Phase input. The loads connected to the different output
terminal are described in detail below:
➢. L- Regular load
Here, the possible connections of loads are light, fan, 6A plug and
many others.
•If a 6A plug is connected to this terminal then the examples of
appliances that can be connected via plug are TV, phone-charger,
light lamp and many more. We can only turn on/off the load
connected to this terminal. A single load with a maximum load
capacity of 1500 watt can be connected here.

Page 8of 19
•If a light with dimmable or non-dimmable driver is connected to this
terminal, we can only turn on/off that light. We cannot dim the
intensity of the light through the Smart Node. If a physical dimmer is
connected in series between L and the light load wire, then using
the physical regular dimming is possible. A single light should not
exceed 750 watts. We do not recommend to group more than 5 LED
lights with this load.
•If a fan is connected to this terminal, we can only turn on/off the fan.
We cannot change the fan speed through the Smart Node. If
physical fan regulator is connected in series between L and the fan
load wire, then changing the fan speed using that physical regular
is possible. Multiple fans with a maximum rating of 1000 watts can
be connected here.

4. Installation Guide
Smart Node Lighting Automation module 2NL installation can be divided
into two parts: first is the hardware connection with the actual loads and second
is the configuration of the device with the Wi-Fi. We will go into deep into each
section below
4.1 Hardware Installation
The LA- 2NL box contains:
1. One 2NL Device
2. One Switch Connector
3. A User Manual
Before going through the steps of installing the hardware, let us first have
a look at the normal wiring behind a switch-board where switches are connected
to the respective load to turn on or off that particular appliance.

Page 11 of 19
The next wiring diagram gives a basic explanation when a 2NL device is
connected behind a switchboard with 2 switches.
Installation Steps
1. Please turn off the power by switching off the MCB for safety purpose.
Then remove the front panel of the respective switchboard and open the
screws of the switch-plate

Page 12 of 19
2. Identify the loads you wish to automate. Disconnect the load wires from
the traditional switches and also, remove the phase (Live) wire from the
switches. Now, label the load wires as per the load connected for further
easy identification. The switchboard should be completely isolated from
the main phase wire, neutral wire and load wires.
3. We need to connect the wire of each load (which were removed from the
switches) to each node of the Smart Node module as per the load type.
The detailed information about the load is explained above.
4. Insert the Heavy Phase to HP terminal, if any heavy load is connected to
HL terminal or else insert regular phase wire to HP. Also, insert phase wire
to two Ph terminals.
5. Insert the Neutral wire to N terminal.
6. Insert the switch connector in the male connector block on the left side of
the green terminals with the small arrow indicated on the switch connector
facing in the front.
7. Connect the black colour from the connector bunch to the common of the
switches (where phase wire was connected previously) in the
switchboard. Now, cross-check whether the phase wire is perfectly
removed from the switchboard.
8. The colour code of the wires which needs to be connected to the other
point of the switches which corresponds to the load as follows:
Smart Node Colour Wires to Switch Connection

9. Now, insert the Switch Board back to its position and then, insert back all
the screws and the outer plate.
10.Turn on the power by switching on the MCB.
11.Now, all the loads would be operable using physical switches. To operate
the loads using
4.2 Wi-Fi Configuration
After successful wiring of the loads with the device, we now need to connect
this hardware with the nearby Wi-Fi.
1. Press the Switch-1 On and Off at a rapid speed, you will hear 3 beeps
from the device. It means the device is in Configure Mode.
2. Now, on your mobile please go to Available Wi-Fi section. You will notice
a new Wi-Fi name on the list with a name similar to “SN-
XXXXXXXXXXXXX”.
3. Connect to this Wi-Fi and wait for some time a webpage will open.

Page 14 of 19
4. If the web page does not appear, then open any webpage and enter
192.168.4.1
5. If you click on the “Reset” button, then the device will be back in the
‘factory default’ mode and the pin of the device will set to default. All
previously added device to any mobile will not work.
6. If you click on “Configure Wi-Fi” button, then you will be redirected to a
page where a list of available Wi-Fi to the device will appear. For your
reference, image is shown below.
7. Select the preferable Wi-Fi of your network and then enter the password
and press ‘Save’ button. We recommend that minimum Wi-Fi strength
should be 50% for perfect operation.

Page 15 of 19
8. If the password is correct, then the device will get connected to your Wi-
Fi network and the Wi-Fi created by the name of “SN-XXXXXXXXXXXXX”
will disappear. If the password inserted is incorrect then the Wi-Fi “SN-
XXXXXXXXXXXXX” will not get disappear and repeat the same process.
9. Install and open Smart Node application, go to ‘Settings’ -> ‘Add New
Device’. Click on ‘Add Device’ button. After 2 seconds, a list of devices in
local will appear and the newly configured device would be there in the list
with the name of its serial number.
10.Now click on this device from the list. You will be asked to enter the
password of the device. Please type default password ‘1234’ and press
‘Login’ button. If the password is entered correctly, then this new device
will appear in the Lighting Automation section.

5. Installation – Special Cases
There are some special cases where the connection becomes a little bit
complex. Some examples are:
5.1 Invertor Connection
If you wish to connect the loads connected with 2NL to work with invertor,
then it is mandatory to insert the Invertor phase wire to Ph terminal (P1). By
default, the load connected to L2 will be connected with the Invertor.

5.2 Two- Way Connection
Two-way connection when using 2NL depends whether we have
connected traditional switches or Smart Node Touch Interface with the 2NL. If
traditional switches are connected with 2NL, then two-way connection is
possible provided an extra wire is present between the two switchboards. If
Smart Node Touch Interface is connected with 2NL, then two-way connection is
not possible.
When 2NL is connected to Traditional switches, then it is possible to make
a two-way connection of switches for loads connected on L2 terminal. It not
possible to make a two-way connection for the load connected with L1.
The following wiring diagram shows a basic two-way connection.

Page 17 of 19
Now, if we install 2NL with traditional switches and wish to make a two-
way connection, then we need to insert an extra wire between the two
switchboards. The common black wire from the connector provided should be
connected as shown below. If no extra wire exists between the two switch
boards, then it is not possible to make a two-way connection.
