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.

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. There is also an option to upload your own firmware, however flashing devices with custom firmware irreversibly voids the device warranty.


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.


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.


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.


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.

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.

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.
