Introduction to Shelly®
Shelly® is a line of innovative microprocessor-managed devices, which allow remote control of electric circuits through a mobile phone, tablet, PC, or home automation system. Shelly® devices can work standalone in a local Wi-Fi network, or they can be operated through cloud home automation services. Shelly Cloud is a service that can be accessed using either the Android or iOS mobile application, or with any internet browser at https://home.shelly.cloud/.
Shelly® devices can be accessed, controlled and monitored remotely from any place where the User has internet connectivity, as long as the devices are connected to a Wi-Fi router and the Internet.
When connected directly to the device's access point, or at the device's IP address on the local Wi-Fi network, the User can access the Shelly® device's embedded Web Interface at http://192.168.33.1. The embedded Web Interface can be used to monitor and control the device, as well as adjust its settings.
Shelly® devices can communicate directly with other Wi-Fi devices through HTTP protocol. An API is provided by Allterco Robotics EOOD. For more information, please visit: https://shelly-api-docs.shelly.cloud/#shelly-family-overview.
Shelly® devices are delivered with factory-installed firmware. If firmware updates are necessary to keep the devices in conformity, including security updates, Allterco Robotics EOOD will provide the updates free of charge through the device embedded Web Interface or Shelly Mobile Application, where the information about the current firmware version is available. The choice to install or not the Device firmware updates is the User’s sole responsibility. Allterco Robotics EOOD shall not be liable for any lack of conformity of the Device caused by failure of the User to install the provided updates in a timely manner.
Shelly® Pro devices are DIN mountable inside the breaker box, and highly suitable for new building construction. All Shelly® Pro devices can be controlled and monitored through Wi-Fi and LAN connections. Bluetooth connection can be used for the inclusion process.
Control your home with your voice
Shelly® devices are compatible with Amazon Alexa and Google Home supported functionalities. Please see our step-by-step guide on: https://shelly.cloud/support/compatibility/.
This use case explains how using Shelly Pro 2/2PM (the Device) you can turn on/off dual lights in a room, hall or corridor from a mobile device and/or multiple physical switches in key locations.

⚠WARNING! Danger of electrocution. Mounting/installation of the Device to the power grid has to be performed with caution, by a qualified electrician!
⚠WARNING! Danger of electrocution. Every change in the connections has to be done after ensuring there is no voltage present at the Device terminals!
⚠CAUTION! Use the Device only with a power grid and appliances which comply with all applicable regulations. A short circuit in the power grid or any appliance connected to the Device may damage the Device!
⚠CAUTION! Тhe Device may be connected to and may control electric circuits and appliances only if they comply with the respective standards and safety norms!
⚠CAUTION! Do not connect the Device to appliances exceeding the given max load!
⚠CAUTION! Connect the Device only in the way shown in these instructions. Any other method could cause damage and/or injury!
⚠CAUTION! Do not use the Device if it has been damaged!
⚠CAUTION! Do not attempt to service or repair the Device yourself!
⚠CAUTION! Before mounting the Device, turn the circuit breakers off, and check that there is no voltage on their terminals. This can be done with a phase tester or multimeter. When you are sure that there is no voltage, you can proceed to mounting and wiring the Device.
Open the mounting bracket by either pressing it from the inside (A) or pulling it out using a screw driver (B), as shown on the image above.
Place Shelly Pro 1/1PM on the DIN rail (1) and push the mounting bracket back to fix Shelly Pro 1/1PM to the DIN rail (2).
Load circuit input terminals
Live (110-240 V) line
Load circuit output terminals
Live (110-240 V) terminal
Local Area Network RJ 45 connector
Create each of the dual lights circuits by connecting all the lights in parallel as shown on the wiring diagram above.
Connect the Neutral lights circuit cable to the Neutral line.
Connect the first lights circuit Live cable to the Device O1 terminal and the second lights circuit Live cable to the Device O2 terminal.
Connect the Device N terminal to the Neutral line.
Mount a circuit breaker for the first lights circuit. Choose the circuit breaker with a current rating corresponding to the connected lights power.
Connect the circuit breaker input terminal to the Live line and the Device I1 terminal to the circuit breaker output terminal.
Mount another circuit breaker for the second lights circuit. Choose the circuit breaker with a current rating corresponding to the connected lights power.
Connect the second circuit breaker input terminal to the Live line and the Device I2 terminal to the second circuit breaker output terminal.
Mount a circuit breaker for the Device power supply and the controlling circuit, and connect its input terminal to the Live line.
Connect the Device L terminal to the output terminal of the circuit breaker for the Device power supply.
Create each controlling circuit by connecting all the switches you want to use to turn on and off the lights of the corresponding light circuit as shown on the wiring diagram above.
Connect one of the first controlling circuit cables to the output terminal of the circuit breaker for the Device power supply, and the other to the Device SW1 terminal.
Connect one of the second controlling circuit cables to the output terminal of the circuit breaker for the Device power supply, and the other to the Device SW2 terminal.
Plug a LAN cable to the Device RJ 45 connector, if you want to control the Device over an Ethernet network.
⚠CAUTION! Plug in or unplug the LAN cable only when the Device is powered off! The LAN cable connector must not be metallic in the parts touched by the user to plug in or unplug the cable.
Make sure you have connected the devices properly and then turn on the circuit breakers.
The red Power LED will be on if the Device is powered, and the Wi-Fi multicolor LED will be on with blue light indicating the Device access point (AP) is activated.
The green LAN LED will be on if the device is connected to an Ethernet network.
Controlling the Device using its embedded Web Interface
Connect to the Device AP (ShellyPro2-XXXXXXXXXXXX/ShellyPro2PM-XXXXXXXXXXXX). Type http://192.168.33.1 in your browser to access the embedded Web Interface.
Click on the Input (0) bar under Switches and attached inputs in the Home screen. Click on the Settings tab. Click on Input mode. Select Switch and click on the Save settings button.
Click on the displayed output (labelled as Output(0)) in the Home page under Switches and attached inputs to access the output settings. Next, in Action on power on select Match input.
Additionally, in the output settings you want to make sure that Switch mode is set to Follow.
Make sure to set these settings for both channels.
Now you can continue with setting up the Device. Check Shelly Pro2 or Shelly Pro 2PM Web Interface Manuals.
Controlling the Device using applications or cloud services
If you choose to use the Device with the Shelly Cloud mobile application and Shelly Cloud service, instructions on how to connect the Device to the Cloud and control it through the Shelly App can be found in the Shelly Application Guide.
The Shelly Mobile Application and Shelly Cloud service are not conditions for the Device to function properly. This Device can be used stand-alone or with various other home automation platforms and protocols.
If you use Shelly Pro 2PM you will be able to measure the momentary voltage and power levels.
Shelly Cloud service allows you to also store statistical data of the energy consumption of your lights within a year.
