To connect to your Shelly Pro 2, connect your device to the Wi-Fi network with a name(SSID) like ShellyPro2 - 84CCA87D1A78.

Once done, through the app on your mobile device or through home.shelly.cloud, you can go into the Settings and search for Device information. There you will find the Device IP and be taken to the Web Interface of Shelly Pro 2.

Device

The settings below concern the entire device.

Sntp server

SNTP synchronizes your device's system time with a server that has already been synchronized by another source. There is already a set server, which is the default one - http://time.google.com, however if there are any problems, you can easily change it and enter a new one in the text box. Changing this setting will reboot the device.

Device name

To change the name of your device, simply type in your desired name into the text box.

Firmware version

In this setting, you can see your device's ID, Firmware version and build ID, as well as the Web build ID. You can also see the available new versions, check for updates and easily update your device.

Location

Your timezone and location will be autodetected, but you can manually change them from this setting by choosing a timezone from the drop-down menu and typing in your latitude and longitude. There is also a button Auto detect location, which will make the device automatically detect the location once again if it failed the previous time.

Reboot

By clicking the button Reboot under this setting, you can reboot your Shelly device directly from the Web Interface.

Factory reset

If you want to bring your device's settings back to how they were originally, you can click the button Reset Device to reset the device to its factory settings.

Authentication

If you enable authentication, you will be asked to type in a password, which you will then use to access the Web UI of the device. Once enabled, to disable it, click the toggle and enter your authentication pass once prompted.

Debug

This setting includes Mqtt, Websocket and Udp debug. To enable any of these, click the toggle switch next to the specific setting. For Udp debug you will also be asked to type in a udp address.

Networks

Wifi

In this setting, you can connect your Shelly Pro 2 to your home network by selecting a Wi-Fi network and typing in its password. Enable Wi-Fi 1, or Wi-Fi 2, or both at the same time. If both Wi-Fi 1 and Wi-Fi 2 are enabled, and the Shelly device disconnects from one of the networks, it will connect to the other. When connecting your device to your home network, you can also set a static IP address for your device to acccess it at.

Access point

Configure the device's AP, including switching it on or off, and setting a password. The access point of the device is an open network by default. The SSID is unique and cannot be changed.

Ethernet

When enabled, you will be able to to connect the device to an ethernet cable network. You can also toggle the setting Set Static IP address and type your desired IP address in the text box. To save the changes you made, click Apply. Changing these settings requires a device reboot.

Cloud

Connecting your Shelly to its cloud allows you to control it remotely, receive notifications and updates about your devices. The default for this setting is for the cloud to be enabled. If you disable the device cloud support, you will lose connection to your device from outside its local network!

Bluetooth

Disable/enable Bluetooth by toggling the switch. The device's default Bluetooth setting is enabled.

Mqtt

Configure the Shelly device to execute actions via MQTT. By default, MQTT is disabled, but you can enable it by toggling the switch. Changing these settings will cause the device to reboot. There are some other settings, such as RPC status notifications over MQTT (which enables you to communicate with your device through RPC notifications) and Generic status update over MQTT (to get an overall status update), which you can enable/disable by toggling the switches on their right. You can also enable SSL and type in your server, username and password, but be aware that enabling SSL will hurt the battery life and most likely shorten it by half.

Scripts

Shelly Pro 2 features scripting capabilities. You can use them to customize and enhance device functionality based on a users’ specific needs. These scripts can take into consideration device state, communicate with other devices, or pull data from external services like weather forecasts. A script is a program, written in a subset of JavaScript. You can find more at https://shelly-api-docs.shelly.cloud/gen2/Scripts/ShellyScriptLanguageFeatures/
