Introduction to Shelly

Shelly is a family of innovative devices that allow remote control of electrical appliances via mobile phone, PC, or home automation system. Shelly devices use WiFi to connect to controlling devices. They can be on the same WiFi network or use remote access (via the Internet). Shelly devices can operate autonomously, without a home automation controller, on the local WiFi network, or via a cloud service from anywhere with Internet access. Shelly devices have an integrated web server through which the user can adjust, control, and monitor the device. Shelly devices have two WiFi modes: Access Point (AP) and Client Mode (CM).

Shelly devices can communicate directly with other WiFi devices via HTTP protocol. An API may be provided by the manufacturer. Shelly devices can be available for monitoring and control even when the user is outside the local WiFi network range, as long as the WiFi router is connected to the Internet. The cloud function can be used, which is activated via the device's web server or via the Shelly Cloud mobile application settings. Users can register and access Shelly Cloud using the Android or iOS mobile applications, or any internet browser and the website: https://my.shelly.cloud/.

Controlling Your Home with Your Voice

All Shelly devices are compatible with Amazon Echo and Google Home. Please consult our step-by-step guide at: https://shelly.cloud/compatibility/Alexa and https://shelly.cloud/compatibility/Assistant.

Installation Instructions

WARNING! Risk of electric shock. Installation must be performed by a qualified person.

WARNING! Risk of electric shock. Even when the device is off, voltage may be present on its terminals. Ensure all local power is disconnected before making any connection changes.

WARNING! Do not connect the device to loads exceeding the indicated maximum load.

WARNING! Connect the device only as indicated in these instructions. Any other method may cause damage and/or injury.

WARNING! Before starting installation, read the accompanying documentation carefully and completely. Failure to follow recommended procedures may lead to malfunction, danger to your life, or violation of law. Allterco Robotics is not responsible for any loss or damage in case of incorrect installation or use of this device.

WARNING! Use the device only with a power adapter that complies with all applicable regulations. A defective power adapter connected to the device may damage it.

RECOMMENDATION! The device can only be connected and control electrical circuits and appliances if they comply with the respective safety standards and norms.

Initial Inclusion

Before installing/mounting the device, ensure the power is off (circuit breakers closed).

Step 1: Install Shelly by following the wiring diagrams and place it in the console. After powering on, Shelly will create its own WiFi Access Point (AP).

ATTENTION! If the device has not created its own WiFi AP with SSID like 'shellyuni-35FA58', please check if the device is connected according to the installation instructions. If you still do not see an active WiFi network with the SSID 'shellyuni-35FA58', or you want to add the device to another WiFi network, reset the device. If the device was powered on, you need to restart it by turning it off and then on again. Power on the Shelly UNI and press the reset button until the board's indicator light turns on. Otherwise, please repeat or contact our customer service at: support@shelly.cloud.

Step 2: Choose 'Add device'. To add more devices later, use the application menu in the top right corner of the main screen and click 'Add device'. Enter the WiFi network name (SSID) and password to which you want to add the device.

Step 3:

• If using iOS (left screenshot): Press the Home button on your iPhone/iPad/iPod. Open Settings > WiFi and connect to the WiFi network created by Shelly, e.g., 'shellyuni-35FA58'.
• If using Android (right screenshot): Your phone/tablet will automatically scan and include all new Shelly devices on the WiFi network you are connected to.

Once device inclusion to the WiFi network is successful, you will see the following pop-up window.

Step 4: Approximately 30 seconds after discovering any new device on the local WiFi network, a 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.

Step 6: Enter a name for the device (in the 'Device Name' field). Choose a room where the device should be placed. You can choose an icon or add an image to make it easier to recognize. Press 'Save Device'.

Step 7: To enable connection to the Shelly Cloud service for remote control and monitoring of the device, press 'YES' in the following pop-up window.

Shelly Device Settings

Once your Shelly device is included in the application, you can control it, change its settings, and automate its operation. To enter the details menu of the respective device, simply click on its name.

In the details menu, you can control the device, as well as change its appearance and settings:

• Edit Device: Allows you to change the device name, room, and image.
• Device Settings: Allows you to change settings. For example, with 'Restrict Login', you can enter a username and password to restrict access to the integrated web interface in Shelly. You can also automate device operations from this menu.
• Timer: To automatically manage power.
  • Auto OFF: After powering on, the power will automatically turn off after a predefined time (in seconds). A value of 0 will cancel the auto-off.
  • Auto ON: After powering off, the power will automatically turn on after a predefined time (in seconds). A value of 0 will cancel the auto-on.
• Weekly Timer: Shelly can automatically turn on/off at a predefined time and day throughout the week. You can add an unlimited number of weekly schedules. This function requires an Internet connection. To use the Internet, a Shelly device must be connected to a local WiFi network with a functional Internet connection.
• Sunrise/Sunset: Shelly receives real-time information via the Internet about sunrise and sunset times in your region. Shelly can automatically turn on or off at sunrise/sunset, or at a specified time before or after sunrise/sunset. This function requires an Internet connection. To use the Internet, a Shelly device must be connected to a local WiFi network with a functional Internet connection.

Device Configuration - Channel Screen

On this screen, you can control, monitor, and change the on/off settings. You can also see the current status of the connected device on Shelly, Button Settings, Enabled, and Disabled. To control Shelly, press the Channel:

• To turn on the connected circuit, press 'Turn ON'.
• To turn off the connected circuit, press 'Turn OFF'.
• Press the icon to go to the previous menu.

Shelly Management Settings

Each Shelly can be configured individually. This allows you to customize each device in a unique way, or consistently, according to your choice.

• Default Power On State: This defines the default state of the channels when they are powered by the electrical grid.
  • ON: By default, when the device is powered on, the connected circuit/appliance will also be powered.
  • OFF: Even if the device is powered on, by default, the socket will not be powered.
• Restore Last State: By default, the device and the connected circuit/appliance will return to the last state they were in (on or off) before the last power off/shutdown.
• Manual Switch Type:
  • Momentary: When using a button.
  • Toggle Switch: When using a switch.
  • Edge Switch: Changes the status with each pulse.
• Auto ON/OFF: Automatic power on/off of the socket and connected device.
  • Auto OFF after: After powering on, the power will automatically turn off after a predefined time (in seconds). A value of 0 will cancel the auto-off.
  • Auto ON after: After powering off, the power will automatically turn on after a predefined time (in seconds). A value of 0 will cancel the auto-start.
• Sunrise/Sunset Times: This function requires an Internet connection. To use the Internet, a Shelly device must be connected to a local WiFi network with a functional Internet connection. Shelly receives real-time information via the Internet about sunrise and sunset times in your region. Shelly can automatically turn on or off at sunrise/sunset, or at a specified time before or after sunrise/sunset.
• ON/OFF Schedule: This function requires an Internet connection. To use the Internet, a Shelly device must be connected to a local WiFi network with a functional Internet connection. Shelly can automatically turn on/off at a predefined time.

Integrated Web Interface

Even without the mobile application, Shelly can be configured and controlled via a browser and a WiFi connection from a mobile phone, tablet, or PC.
