Shelly 1PM Mini Gen3 web interface guide
Overview
Shelly devices provide a local web interface to control and configure 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, set schedules and configure actions to be executed when certain conditions are met, configure the device and much more.
Note that you do not need internet connection or Shelly Cloud to use the local web interface - the only requirement is that your browser must be in the same WiFi network as your Shelly device.
Accessing the web interface
For devices with an access point:
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.
For Wi-Fi devices without an access point:
Connect the device to your Wi-Fi network.
While you’re connected to that network, go to the IP address shown on your device.
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 preferred 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 recommended 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.
Header
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, as well as an icon that shows if there are any new firmware updates for your device. 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.
Footer
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.
Main menu
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.
Main content
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.
Main Menu
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.
Home page
In the web interface, you will see six icons in the header, including one for AP, Wi-Fi, Bluetooth, Cloud, and MQTT connection. Here is what the different status colors mean:

The output and input are displayed in the Home page, and clicking on them will reveal a set of specific settings, explained below.
Output Settings
Name
Name/rename the output.
Input/output settings
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 (not present as an option in all devices)- using the Analog input, the device determines its 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.
One button dimming control (only for devices that support dimming) - Using just one button, your device can both turn ON/OFF and also be dimmed up/down. Every push of the button toggles the output state. Holding down will dim the light, every hold changes the direction of dimming (up or down).
Dual button dim mode (only for devices that support dimming and can have 2 inputs)- 2 separate inputs that control the different directions of dimming (up and down).
Action on power on:
This setting is usually used 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, the device will turn on and the same applies when the switch is flipped to OFF.
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.
Protections:Overpower in watts - Configure the Shelly switch relay to turn off when power consumption reaches a certain value. The maximum allowed power value is equal to the maximum current times the maximum voltage.
Overcurrent in amperes - If the supply current becomes above a certain value, the channel will be switched off.
Overvoltage in volts - If the supply voltage becomes above a certain value, the channel will be switched off.
Reset counters
Sets all input readings to 0.
Actions
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.
Schedules
This function requires a working connection to the Internet, so the device can synchronize the time. It allows you to create, view, edit, and delete schedules.
There are two types of schedules: Basic and Advanced.
To create a basic schedule:
Select the day(s) of the week.
Choose a time interval: time, sunrise, or sunset.
Set the time for the specified day(s):
Time: Click the 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 (or do specified action) automatically at sunrise/sunset, or at a specified time before or after sunrise/sunset. Click the up/down button, or type in a number, to set a time in hours and minutes.
To create an advanced schedule:
The advanced schedule function uses cron to execute jobs with a single schedule, instead of using a few basic schedules.
Creating an advanced schedule differs from creating a basic schedule, because of the When to execute menu.
It prompts you to select one or multiple values, a range of values, or a step between values (Choose one of the three by clicking on the Select, Range, or Step button for each value) for:
Seconds (0-59)
Minutes (0-59)
Hours (0-23)
Days (1-31)
Months (JAN-DEC)
Weekdays (SUN-SAT)
To create a schedule that happens every second/minute/hour/day/month/weekday, simply tick the box below the values in the desired section (seconds, minutes, hours, days, months, or weekdays). Additionally, you can use the sunrise/sunset offset by ticking the box next to this option. Doing so will bring up a new menu with hours and minutes. Leaving the hours and minutes and selecting either sunrise or sunset will make the schedule occur exactly at sunrise or sunset. Changing the hours and minutes values will create an offset, so entering negative values will make the schedule occur exactly [set hours and/or minutes] before sunrise/sunset while entering positive values will make the schedule occur [set hours and/or minutes] after sunrise/sunset. You cannot enter a positive value for one (hours/minutes) and a negative value for the other.
After that, simply specify the action you want your device to perform in the Do what section. Click Save once you’re done to save the new schedule.
Timers
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).
Input settings

This setting is usually used 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, the device will turn on and the same applies when the switch is flipped to OFF.
Invert
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
Enabling this setting will allow you to factory reset the device from its input and not only through the app or web interface.
Settings
Network settings
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.
Wi-Fi - 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.
Connectivity
Cloud -Connecting your Shelly to its cloud allows you to control it remotely, and 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.
RPC over UDP - Communicate with your device and send requests through a Remote Procedure Call (RPC) over a User Datagram Protocol (UDP) server. This can be useful in controlling and monitoring your device remotely, without the need for a dedicated server or connection.
To use this setting, you'll need to enter the listen port and destination address for the UDP server. The listen port is the port number that the device will listen on for incoming requests, while the destination address is the IP address of the server to which the requests will be sent.
Once you've entered the required information, you can use the RPC over UDP protocol to send requests to your device and receive responses.
Device settings
Device name (info) - See your device’s ID, the Wi-Fi it’s connected to, and the Wi-Fi RSSI.
Reboot - 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 - 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 (TLS Configuration) - Upload custom certificate authority, client certificate, and client key by dragging and dropping the file(s), or by browsing your files, which you can do by clicking the designated button. Click Upload to upload the files, and Clear to remove files you don’t want to upload.
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.
Scripts
This device features scripting capabilities. You can use them to customize and enhance device functionality based on a user’s 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.
Components
Creating a component
The Components setting allows the user to create Dynamic Components, which don’t initially exist in the device. Virtual components, a type of dynamic component, are used to store or transfer data between scripts or runs and display the script’s functionality on the home page. Components can be grouped together; only the groups and the components inside of them will be displayed on the home page. Components that don’t belong to a group will not be visualized there. The number of components and groups of components per device is limited.
To create a component:
Click the Create new button next to User-defined components.
Select the type of component you’d like to create - Boolean, Number, Text, Enum, or Button. When created, each component type has Name, View, and Custom Icon URL fields, which you have to fill in. The Custom Icon URL field isn’t required, but it can be used to customise how your components look in the home page. You can rename or delete a component, as well as create actions for it, using the buttons located next to each component.
The different component types may have additional fields, specific to that type. They are explained below
The Boolean component type stores a true/false value and has two different titles that the user can enter depending on if its value is true or false, as well as two separate icons. The drop-down menu for the default value will include the different states of your device. The view options are Hidden, Toggle, and Label. The Toggle view displays a toggle button, so the component’s value changes on each hit. The Label view shows the title for the component’s value.
The Number component type stores values between -999999999999999 and 999999999999999. The default value should be a number in this range. You can also change the unit and step. The view options are Hidden, Field, Slider, Progress bar, and Label. The Field view shows an input field, the Label view displays the value, the Progress bar view visually represents progress, and the Slider view displays a slider interface for interaction.
The Text component type stores a string with up to 255 characters. The view options are Hidden, Field, Label, and Image. The Field view shows an input field, the Label view displays the title, and the Image view requires a URL value, which it uses to display an image.
The Enum component type stores a group of named constants. The view options are Hidden, Dropdown, and Label. If you select Label view, the component will display the title by default, but if an image is specified, it will take precedence and be shown instead.
The Button component type provides a simulated virtual input that allows users to interact with the user interface by registering and reporting clicks. It then sends notifications through connected channels and can be used to trigger automations, and activate webhooks. It features two view options - Button, which displays the button component in your home page, and Hidden.
If a component is set to Hidden, it won’t be displayed in the home page. Otherwise, your component groups will appear below your device’s input(s) and/or output(s) and will display the components, which are part of those groups.
Creating a group of components
To create a group:
Click on the + next to User-defined groups, and you’ll be taken to the group creation menu.
Enter the name of the group.
Select the desired components that you’d like to have in that group.
Editing your groups menu is done through the pencil icon next to the + and it allows you to change the order of your groups by clicking on the up and down arrows to move a group up or down.
Component actions
The Actions menu is now structured based on component type. So, you can create actions for your components and they’ll be separated into the aforementioned five categories.
Scripting
Components can be included in scripts and programmed to change values depending on a condition. To specify a component in a script, you’ll need to use its ID. Component IDs start from 200 and are limited to 299. You’ll be able to see your component’s ID in the Components menu.
BTHome components
BTHome components allow you to create virtual/dynamic components paired to real devices emitting BTHome packets, such as the Shelly BLU devices. To use BTHome components, a successful Bluetooth connection must be established first. A message will appear informing you if the Bluetooth observer is disabled, as well as a button to enable it and reboot your device.
Once a connection has been made, to add a BTHome (Bluetooth) device, click on the + sign next to BTHome components. The device will scan for available Bluetooth devices, but you can click on the Scan button to scan again. Any found devices will appear below that button. In order for a device to be found during the scan, that device needs to be in pairing mode, which is done by holding down the device button. Another option for adding a device is using a MAC address. To do that, click on Add device by MAC address and enter the MAC address of the device you wish to add.
To add sensors, click Configure next to the Bluetooth device of your choice. On this screen, you can name your BTHome (Bluetooth) device, add an encryption key, as well as enter a Custom Icon URL to customise the look of the BTHome component in the home page. The encryption key is used for packet decryption and can be retrieved using the Shelly BLU Debug application.
Below the encryption key field are the supported sensors, which you can add by clicking on the + sign next to the ones you wish to add. Once added, a pencil icon appears next to the sensor and by clicking it you can edit its name, add a Custom Icon URL, or use the trash can icon to delete the sensor entirely.
To save your BTHome component, click on Save settings. To delete a component, click on the trash can icon above the text fields.
To edit a BTHome component, click on the gear wheel icon. You’ll be taken to its settings, which is the same screen as the one you see when you’re adding the component.
KNX
KNX is a standardized communication protocol for building automation. It's used for controlling and managing various aspects of a building's systems, including lighting, heating, ventilation, security, energy management, and more. KNX allows different devices and systems from different manufacturers to communicate with each other over a common network.
General
To use KNX, click on the tick next to Enable. Next, enter a unique individual address for your device in the KNX network.
In the Multicast settings, enter the IP address (referred to as Address) for the multicast group you want your device to communicate in. The addresses range from 224.0.0.0 to 239.255.255.255. The Port setting designates the port number within that multicast group where communication occurs. Together, they define the destination for multicast messages within a network.
Inputs
Depending on the device, you will have a different number of inputs in this menu. For each input, select an Input state, which can be Switch, or Button, or specifically for devices with dimming - Single-button dimming, or Dual-button dimming.
Underneath, depending on the previously selected input state, you’ll notice one or more objects, as well as text on the right of the object, identifying its size and data type. For the different input modes, they’re:
Switch - Has one object, called Switch object, with a size of 1-bit, and DPT (Data Point Type) 1.001, which stands for a switch type with two states - on/off (1/0). You can add up to three Switch objects, using the Add button.
Button - First, select a function for the button - ON, OFF, or Toggle. The button input state has two objects - a Single-push object, and a Feedback object. You can add up to three Single-push objects, using the Add button, and one Feedback object. Both are of type Switch, with a size of 1-bit, and DPT (Data Point Type) 1.001, which stands for a switch type with two states - on/off (1/0). The Feedback object can be the same as the Single-push object, or another address can be entered for it, which is done by unticking the Same as Single-push object setting and entering a new address.
Single-button dimming - First, select a dimming step, ranging from full dimming to 1/64 dimming. This changes the dimming speed. Full dimming will be the fastest because it will dim from 0 to 100% at the set speed, whereas 1/64 dimming will dim 1/64 of the full dimming for the same amount of time. This input state has three objects - a Single-push, Long-push, and Feedback object. You can add up to three Single-push and Long-push objects, using the Add button, and one Feedback object, which can be the same as the Single-push object, or another address can be entered for it, which is done by unticking the Same as Single-push object setting and entering a new address. The Single-push and Feedback objects are of type Switch, with a size of 1-bit, and DPT (Data Point Type) 1.001, which stands for a switch type with two states - on/off (1/0). The Long-push object is for dimming control, which has a size of 4-bit and a DPT (Data Point Type) of 3.007. The Control Dimming object consists of two values - one to indicate an increase (1) or decrease (0), and one corresponding to the step.
Dual-button dimming - First, select a dimming step, ranging from full dimming to 1/64 dimming. This changes the dimming speed. Full dimming will be the fastest because it will dim from 0 to 100% at the set speed, whereas 1/64 dimming will dim 1/64 of the full dimming for the same amount of time. Next, select the direction of dimming - up/ switch on, or down/ switch off. This input state has two objects - a Single-push and a Long-push object. You can add up to three Single-push and Long-push objects, using the Add button. The Single-push object is of type Switch, with a size of 1-bit, and DPT (Data Point Type) 1.001, which stands for a switch type with two states - on/off (1/0). The Long-push object is for dimming control, which has a size of 4-bit and a DPT (Data Point Type) of 3.007. The Control Dimming object consists of two values - one to indicate an increase (1) or decrease (0), and one corresponding to the step.
Outputs
The outputs menu is separated into three sections - Commands, Feedbacks, and Measurements. For each type of object in Commands, you can have up to five objects. These are the types of objects each section has:
Commands:
Switch object - Has a size of 1-bit, and DPT of 1.001, which stands for a switch type with two states - on/off (1/0).
Feedbacks:
Feedback object - Has a size of 1-bit, and DPT of 1.001, which stands for a switch type with two states - on/off (1/0). The Feedback object is used to report the device state.
Measurements (These object types are of size 4-byte.):
Voltage object - Has a DPT of 14.027, which stands for an Electric potential object of type Double with three values.
Current object - Has a DPT of 14.019, which stands for an Electric current object of type Double with three values.
Active power object - Has a DPT of 14.056, which stands for a Power object of type Double with three values.
Active energy object - Has a DPT of 13.010, which stands for an Active energy object of type long, measured in watt-hours.
Depending on the device, you might have additional types of objects in the sections, such as:
Commands:
Relative dimming object - Has a size of 4-bit and a DPT of 3.007, which stands for a Control Dimming object consisting of two values - one to indicate an increase (1) or decrease (0), and one corresponding to the step.
Absolute dimming object - Has a size of 1 byte, and a DPT of 5.001, which stands for a Scaling object consisting of a value from 1 to 100 to represent percentage.
Measurements (These object types are of size 4-byte.):
Generated energy object - Has a DPT of 13.010, which stands for an Active energy object of type long, measured in watt-hours.
Advanced Settings
Upon clicking on the arrow next to this setting, you will reveal the advanced settings. They are explained below.
KVS
KVS stands for Key-Value Storage and is a type of non-relational database, which works by using a simple key-value method to store data. In one device, you can store up to 50 key-value pairs. Upon clicking on the Add value button, you will be taken to the value creation screen, which prompts you to enter a key (up to 42 characters), and value (up to 253 characters). You’ll notice under the text box for the value is the current value type. By default, the value type is Number, but by entering text, the type will change to String. To save the key, simply click the Save button. To edit an existing value, simply click on it. To delete a key-value pair, click the Delete button that appears below it when you go to edit the key. Clicking on the question mark next to the setting name will take you to the API documentation, which will provide you with further information on how the KVS works for Shelly devices.
Diagnostics
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 log data.
