Shelly Uni: Installation and Configuration Guide

Initial Inclusion and Wiring

Before installing or mounting the device, ensure the power grid is turned off (breakers down).

Sensor Connections

• DS18B20 Sensor: Connect as shown in Figure 1.
• DHT22 Sensor: Connect using the scheme in Figure 2.

Switch and Sensor Connections

• Binary Sensor (Reed Ampule): Connect using the scheme in Figure 3A for DC power supply or Figure 3B for AC power supply.
• Button or Switch: Connect using the scheme in Figure 4A for DC power supply or Figure 4B for AC power supply.
• ADC Wiring: Use the scheme shown in Figure 6.

Control of Inputs

The device reads standard logical levels, independent of applied voltage (potential free). It cannot work with programmed limits of the levels as they are not ADC attached.

• AC Input (12V up to 24V): Measured as logical "1" (HIGH) if voltage is above 12V, and logical "0" (LOW) if below 12V.
• DC Input (2.2V up to 36V): Measured as logical "1" (HIGH) if voltage is above 2.2V, and logical "0" (LOW) if below 2.2V.
• Maximum allowed voltage is 36V DC / 24V AC.

Shelly Cloud Mobile Application

Shelly Cloud gives you the opportunity to control and adjust all Shelly® devices from anywhere in the world. All you need is an Internet connection and our mobile application, installed on your smartphone or tablet.

Registration

The first time you load the Shelly Cloud mobile app, you have to create an account which can manage all your Shelly® devices. WARNING! Be careful when you type your e-mail address during the registration, as it will be used in case you forget your password.

Forgotten Password

In case you forget or lose your password, just enter the e-mail address you have used in your registration. You will receive instructions to change your password.

First Steps in the App

After registering, create your first room (or rooms), where you are going to add and use your Shelly devices.

Scenes

Shelly Cloud gives you the opportunity to create scenes for automatic turning on or off of the Devices at predefined hours or based on other parameters like temperature, humidity, light etc. (with available sensor in Shelly Cloud). Shelly Cloud allows easy control and monitoring using a mobile phone, tablet or PC.

Device Inclusion (App)

1. Install Device: Install the Shelly device to the power grid following the Installation Instructions included with the Device. After turning the power on, Shelly will create its own WiFi Access Point (AP) with an SSID like "shellyuni-XXXXXX". WARNING! If the Device has not created its own AP WiFi network, reset the Device. If the Device has been powered on, restart it by powering it off and on again. Power on Shelly Uni and press the reset switch button until the LED on the board goes ON. If not, repeat or contact customer support at support@shelly.cloud.
2. Connect to Shelly AP: If using iOS, go to Settings > WiFi and connect to the network created by Shelly (e.g., shellyuni-35FA58). If using Android, your phone will automatically scan and include new Shelly Devices in the WiFi network you are connected to.
3. Add Device in App: Open the Shelly app, select "Add Device" from the menu. Type the name (SSID) and password for the WiFi network to which you want to add the Device.
4. Discovery: Approximately 30 seconds after discovery of any new Devices on the local WiFi network, a list will be displayed by default in the "Discovered Devices" room.
5. Select Device: Enter "Discovered Devices" and choose the Device you want to include in your account.
6. Name and Room: Enter a name for the Device (in the Device Name field). Choose a Room, in which the Device has to be positioned. You can choose an icon or add a picture to make it easier to recognize. Press "Save Device".
7. Connect to Cloud: To enable connection to the Shelly Cloud service for remote control and monitoring, press "YES" on the following pop-up.

Shelly Device Settings (App)

After 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.

• Edit Device: Allows you to change the Device's name, room, and picture.
• Device Settings: Allows you to change settings. For example, with "Restrict login", you may enter a username and password to restrict access to the embedded web interface. You may also automate Device operations from this menu.
• Timer: Manage the power supply automatically.
  • Auto OFF: After turning on, the power supply will automatically shut down after a predefined time (in seconds). A value of 0 cancels the automatic shutdown.
  • Auto ON: After turning off, the power supply will be automatically turned on after a predefined time (in seconds). A value of 0 cancels the automatic power-on.
• Weekly Schedule: Shelly may turn on/off automatically at a predefined time and day throughout the week. This function requires an Internet connection.
• Sunrise/Sunset: Shelly receives actual information through the Internet about the time of sunrise and sunset in your area. Shelly may turn on or off automatically at sunrise/sunset, or at a specified time before or after sunrise/sunset. This function requires an Internet connection.

The Embedded Web Interface

Even without the mobile app, Shelly can be set and controlled through a browser and WiFi connection of a mobile phone, tablet, or PC.

Abbreviations Used

• Shelly-ID: The unique name of the Device, consisting of 6 or more characters (e.g., 35FA58).
• SSID: The name of the WiFi network created by the Device (e.g., shellyuni-35FA58).
• Access Point (AP): The mode in which the Device creates its own WiFi connection point with the respective name (SSID).
• Client Mode (CM): The mode in which the Device is connected to another WiFi network.

Initial Inclusion (Web Interface)

1. Install and Power On: Install Shelly to the power grid following the schemes described above and place it into the console. After turning the power on, Shelly will create its own WiFi network (AP). WARNING! If you do not see an active WiFi network with SSID like shellyuni-35FA58, reset the Device. Restart by powering it off and on again. Power on Shelly Uni and press the reset switch button until the LED on the board goes ON. If not, repeat or contact customer support at support@shelly.cloud.
2. Connect to AP: Connect your phone, tablet, or PC to the Shelly AP (e.g., "shellyuni-35FA58").
