• SW2 - Switch input 2 for on/off/dimming
• O - Output
• L - Line input (110-240V)
• N - Neutral input (Zero)
⚠CAUTION! When using the device without neutral, Shelly Dimmer
2 requires at least 10W of power consumption, in order to operate.
If the connected light has a smaller power consumption, then Shelly
Bypass is required for the operation of the Device.
The Shelly smart WiFi dimmer by Allterco Robotics is intended to
be installed directly to your lights in order to control and dim the
light. It is intended to be mounted into a standard in-wall console,
behind the light switches or other places with limited space. Shelly
may work as a standalone device or as an accessory to a home
automation controller.
⚠CAUTION! Shelly dimmer cannot be connected and operate a fan.
Doing so may cause damage to the unit or fan, including causing
a re!
⚠CAUTION! For multiple bulbs connected to one Dimmer 2, all
bulbs need to be equal in power load and technology!

Introduction to Shelly
Shelly® is a family of innovative Devices, which allow remote
control of electric appli-ances through mobile phone, PC or home
automation system. Shelly® uses WiFi to connect to the devices
controlling it. They can be in the same WiFi network or they can
use remote access (through the Internet). Shelly® may work stand-
alone, without being managed by a home automation controller,
in the local WiFi network, as well as through a cloud service, from
everywhere the User has Internet access.
Shelly® has an integrated web server, through which the User
may adjust, control and monitor the Device. Shelly® has two WiFi
modes - access Point (AP) and Client mode (CM). To operate in
Client Mode, a WiFi router must be located within the range of the
Device. Shelly® devices can communicate directly with other WiFi
devices through HTTP protocol.
An API can be provided by the Manufacturer. Shelly® devices may
be available for monitor and control even if the User is outside the
range of the local WiFi network, as long as the WiFi router is con-
nected to the Internet. The cloud function could be used, which is
activated through the web server of the Device or through the set-
tings in the Shelly Cloud mobile application.
The User can register and access Shelly Cloud, using either Android
or iOS mobile applications, or any internet browser and the web
site: https://my.Shelly.cloud/.

Device Inclusion
To add a new Shelly device, install it to the power grid fol-
lowing the Installation Instructions included with the Device.
Step 1
After the installation of Shelly following the Instalation In-
structions and the power is turned on, Shelly will create its
own WiFi Access Point (AP).
⚠WARNING! In case the Device has not created its own WiFi
network with SSID like shellydimmer2-35FA58 check if you
have connected Shelly correctly by the wiring schemes. If you
do not see an active WiFi network with SSID like shellydim-
mer2-35FA58, reset the Device. If the Device has been pow-
ered on, you have to power it off and on again. After turning the
power on, you have 60 seconds to press 5 consecutive times
either switch connected I1/I2. Or if you have physical access
to the Device, press and hold the reset button for 10 seconds.
Shelly should return to AP Mode. If not, please repeat or con-
tact our customer support at [email protected]
Step 2
Choose “Add Device”. In order to add more Devices later, use
the app menu at the top right corner of the main screen and
click “Add Device”. Type the name (SSID) and password for
the WiFi network, to which you want to add the Device.
Step 3
If using iOS: you will see the following screen:
Press the home button of your iPhone/iPad/iPod. Open
Settings > WiFi and connect to the WiFi network created by
Shelly, e.g. shellyswitch25-35FA58. If using Android your
phone/tablet will automatically scan and include all new
Shelly Devices in the WiFi network that you are connected to.
Upon successful Device Inclusion to the WiFi network you will
see the following pop-up:
Step 4
Approximately 30 seconds after discovery of any new Devic-
es оn the local WiFi network, а list will be displayed by default
in the “Discovered Devices” room.
Step 5
Enter Discovered Devices and choose the Device you want to
include in your account.
