The web interface serves as an agile web server, providing you with a seamless gateway to access and oversee your devices through a standard web browser on either your computer or mobile device. Its functionality encompasses an array of adjustment and control features, including the ability to power your device on or off, track energy consumption, set schedules, and execute scripts as needed.
Accessing the web interface
Connect your device to a Wi-Fi network with a name (SSID) that follows this format: "DeviceName-XXXXXXXXXX", where ‘DeviceName’ is the name of the device you’d like to connect to, while 'XXXXXXXXXX' represents a unique combination of letters and numbers, constituting the device ID. For instance, the SSID might appear as "ShellyPlus1PM - 84CCA87D7CDC”.
After establishing a connection to the device’s Access Point / AP (the Wi-Fi network mentioned in step 1), accessing the web interface is done by entering the universal IP address for all Shelly devices 192.168.33.1 in your browser.
You are now in the web interface of your device.
Connecting your device to a Wi-Fi network
Some of the settings you’ll see in the web interface are only available if the device is connected to the internet. To do that, follow these steps:
From the Web interface, navigate to Settings>Wi-Fi.
Either input or select your preffered Wi-Fi network and then enter its password. Alternatively, connecting to an open network is also an option, facilitated by selecting the checkbox for connecting to open Wi-Fi networks. Additionally, it is recommended to set a static IP address.
Allow your device a few seconds, so it can try to connect to the Wi-Fi network you provided. If the password you typed in is incorrect, or the Wi-Fi network lacks sufficient strength or stability, a message will be displayed in the web interface, notifying you that a connection couldn’t be established. Upon successful connection to the Wi-Fi, a link, containing the new IP address will appear as text above the Wi-Fi settings. Simply copy and paste this link into your browser.
You are now in the web interface of your internet-connected device. The next time you need to access the web UI, simply connect to the same Wi-Fi network as your device and type in the new IP address, obtained in step 3. Setting a static IP address is reccomended, because it guarantees consistent accessibility at that specific address.
Understanding the layout
The web interface can be divided into four main sections - the header, footer, main menu and main content.
The header consists of two components - the name of your device on the left and a few icons, which display your device’s main network and connectivity features on the right. These icons can encompass functionalities such as Wi-Fi, Bluetooth, MQTT, and more. Hovering with your mouse on an icon will provide you with further information. You’ll find a legend with the meaning of each icon in the web interface guide of each device. Please note that the individual guides explain only the connectivity features available for that specific device.
At the bottom of the screen from left to right in order are the device model name, its ID, the version of the web interface, the firmware version of the device and finally, the current time. Some previous versions of the web interface do not include all of these components.
The main menu in the desktop version of the web interface is on the left, whereas on mobile, it looks like a hamburger menu with an icon of three horizontal lines, stacked on top of each other. The menu contains different things, depending on the device, but clicking an item from it takes you to a different page. You can also use it to get back to the Home page by clicking Home.
By clicking on an item from the main menu, you’ll be able to navigate through the web interface. Everything that you see on the screen, excluding the header, footer and main menu is considered main content.
*Please note that not all of the web interface screenshots displayed at the top of each web interface guide page (where there is a screenshot present) are of the latest version. Therefore, they may look a bit different than the latest version and may not represent the look of every device's web interface.
Below are explanations of each setting in the main menu, including what is visualised as main content upon clicking on the different settings. A brief introduction of the icons in the header, specific to this device, is also present in the Home page explanation. Note that the header is present in all of the screens, not just the Home page.
In the web interface, you will see five icons in the header, including one for AP, Wi-Fi, Bluetooth, Cloud and MQTT connection. Here is what the different status colors mean:
You will see the two outputs and inputs, which are connected to them, in the home page. Next to the outputs(labelled as output, but the name can be changed in the settings) are power buttons, which control them, and under each of the outputs are the voltage readings. If you have any add-on peripherals, they will also be displayed in this page.
Change the displayed output name in the home page through this setting.
Select input mode:
Button - every button press toggles the state of the device output.
Switch - the position of the switch corresponds to the state of the device output.
Analog - using the Analog input, the device determines it’s brightness percentage based on the percentage of the input.
Set output type:
Toggle Switch (Switch only) - The device will act as a flip switch with one state for ON and one for OFF. If the Input is in Analog mode, the device will follow the analog input’s state.
Momentary Switch (Button only) - Every push of the button toggles the state of the device output. If your switch is ON, it will turn OFF and vice versa.
Edge Switch (Switch only) - Each change of the switch’s position toggles the state of the device output.
Detached Switch - The input becomes detached (separated) from the output and doesn’t have an effect on it. Essentially, you won’t be able to control your light through the input.
Action on power on:
This setting is usually used for when a power outage occurs and “power on” refers to when the electricity is restored and the device is powered again.
Turn ON - When powered, the device will turn on.
Turn OFF - When powered, the device will be off.
Restore last known state of output/relay - When powered, the output’s state will be as it was the last time the device was ON (before the power loss).
Current state of the switch (Toggle Switch only) - follows the state of the switch, so if it’s flipped to ON, it the device will turn on and the same applies to when the switch is flipped to OFF.
Action on power on
Set an action for your device to complete on power on. You can turn off this setting or choose Restore last to restore the last action your device completed. Additionally, you can choose Match Input, which operates your device, according to the state of the switch or button, connected to it.
Choose the type of appliance your device is connected to from the list, which includes General, Relay, Lights, Socket, Heating, and Entertainment.
Max voltage protection
If the supply voltage becomes above a certain value, the channel will be switched off.
Max current protection
If the supply current becomes above a certain value, the channel will be switched off.
Max power protection
Configure the Shelly switch relay to turn off when power consumption reaches a certain value. Maximum allowed power value is equal to maximum current times maximum voltage.
External application/consumption type
This setting is relevant when integrating the device with third-party home automation systems. The purpose is to specify the necessary information or configuration required by the external system to interact with the device.
When you are using third-party home automation systems to control your device, it is recommended to refer to their documentation or user guide to determine what needs to be entered in this field. The documentation of the third-party system will typically outline the required parameters, credentials, or any other details that should be provided to establish communication between itself and the Shelly device.
However, if you are using the device exclusively with the Shelly app, you can disregard the External consumption type field. The app does not require any additional configuration in this regard, as it has its own built-in mechanisms for communicating with and controlling the device.
If, for any reason, you wish to remove or delete the external consumption type from the device's settings, you can do so by simply leaving the External consumption type field empty and clicking the Save settings button. By doing this, you effectively disable the external consumption type and revert to the device's default behavior or rely solely on the Shelly app for control and automation.
Configure the actions for your device - create new actions, edit existing actions or delete actions. When creating actions for your device you will need to specify the condition on which the action occurs. You can also set a duration for your actions, as well as a URL to be hit when the condition for the action is met.
Create a weekly schedule for the day(s) and time(s) you want the corresponding device to turn On/Off automatically. You may add up to 20 weekly schedules with 5 URLs each. To add a new schedule, first enable weekly schedules by ticking the box next to Enable schedule timer. After that, click Add and then:
Select the day(s) of the week.
Choose time interval: time, sunrise, or sunset.
Set the time for the specified day(s):
Time: Click up/down button, or type in a number, to set a time in hours and minutes.
Sunset/Sunrise: The Shelly device may turn on/off automatically at sunrise/sunset, or at a specified time before or after sunrise/sunset. Click up/down button, or type in a number, to set a time in hours and minutes.
This function requires a working connection to the Internet, so the device can synchronize the time. In this setting you can also view, delete and edit your existing schedules.
Allows you to manage the power supply automatically. You may use:
Auto on: After turning off, the relay output will be automatically turned on after a predefined period of time (in seconds).
Auto off: After turning on, the relay output will be automatically turned off after a predefined period of time (in seconds).
Change the displayed input name in the home page through its settings.
Choose one of the following:
Button - every button press toggles the state of the device output.
Switch - the position of the switch corresponds to the state of the device output.
This setting can also be titled “Switch mode” for some devices.
Attached to output
Configure whether the input is attached or detached from the output of the device. When the input is attached, it is connected to the relay(s) and can control them directly using the switch(es) on the device.
On the other hand, when the input is detached, it is separated from the relay(s) and cannot control them using the switch(es) on the device. In this case, the relay(s) can still be controlled remotely, such as through the web interface or the Shelly app. However, you can still create actions for the input, which will be triggered when the input signal is detected.
This setting allows you to invert the logic of the input signal, effectively reversing the behavior of the device. By default, when the input signal is ON, the device responds by turning ON. When the input signal is OFF, the device turns OFF.
However, if you enable the "Invert Input" setting, the opposite will occur. When the input signal is ON, the device will turn OFF, and when the input signal is OFF, the device will turn ON. This setting can be useful in situations where the device's behavior needs to be reversed.
Factory reset from input
Enable the device to be factory reset through the input.
Once you enable and add the Add-on and its sensors you can see all of the information in this setting. To see exactly how to set it up through the web interface and learn how to navigate its settings, read the Shelly Plus Add-on web interface guide.
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.
WiFi - Register the Shelly device to connect to up to 2 different Wi-Fi networks.
Either input or select the Wi-Fi network. Can select an open network, and also set a static IP address.
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.
Bluetooth - Disable/enable Bluetooth by toggling the switch. The device's default Bluetooth setting is enabled.
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!
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.
Outbound Websocket - Specifies whether the HTTP channel creates an I/O exception when an inbound connection is closed while still in use by the servlet. By default, this setting is disabled. To enable it, click the toggle switch next to Enable. Enter your service address in the text box and from the drop-down menu under SSL Connectivity choose *, ca.pem or user_ca.pem.
Range extender - Turning on the Range extender feature creates a hotspot that you can connect Wi-Fi devices to. If a Shelly device with the range extender enabled is connected to a Wi-Fi router and the Internet, all devices connected to it are also connected to the router and the Internet.
Even if the Shelly device is not connected to a Wi-Fi router, all devices connected to it can still communicate with it and with each other.
Device info - See your device’s ID, the Wi-Fi it’s connected to and the Wi-Fi RSSI.
Reboot device - After clicking on the Reboot button, you will be asked if you’re sure you want to reboot your device. Click OK for device reboot and Cancel if you don’t want the device to reboot.
Factory reset device - By clicking on the Reset button, your device’s settings will all be reset to the default. Any changes you’ve made will be reverted. You can confirm that you want the device to factory reset by clicking OK on the pop-up, or Cancel to cancel the factory reset.
Location and timezone - 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.
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.
Firmware - 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.
User certificate - Upload custom SSL certificate by dragging and dropping the file or by browsing your files, which you can do by clicking the designated button.
Eco mode - Reduce energy consumption on the device by lowering CPU frequency and modem activity while in Eco Mode. To enable this setting click the toggle switch next to Enable eco mode and then click the Apply button to save the changes.
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.
Units - Choose the units the measured data will be displayed in.
From this setting you can download the debug logs. Enabling the debug log without a reason isn’t recommended, since your device will be slowed down and this setting will cause aging of the flash memory. If you do decide to enable it, you can also download the previous and current logs. Be aware that leaving this page will reset the logger and logged data.
