Shelly

Integrate Shelly devices into Home Assistant.

Configuration

To add the Shelly integration to your Home Assistant instance, use this My button:

Shelly can be auto-discovered by Home Assistant. If an instance was found, it will be shown as Discovered. You can then set it up right away.

Shelly device generations

There are three generations of devices and all generations are supported by this integration. There are some differences in how devices should be configured and in the naming of entities and devices between generations.

Shelly device configuration (generation 1)

Generation 1 devices use the CoIoT protocol to communicate with the integration. CoIoT must be enabled in the device settings. Navigate to the local IP address of your Shelly device, Internet & Security > ADVANCED - DEVELOPER SETTINGS and check the box Enable CoIoT.

We recommend using unicast for communication. To enable this, enter the local IP address of the Home Assistant server and port 5683 into the CoIoT peer field and push SAVE button. This is mandatory for battery operated devices (even if USB connected). After changing the CoIoT peer, the Shelly device needs to be manually restarted.

Home Assistant will display a repair issue for the Shelly device if push updates from this device do not reach the Home Assistant server.

The list below will help you diagnose and fix the problem:

  • Check if your Shelly devices have a properly configured CoIoT peer.
  • If you can’t find the CoIoT peer settings in the device’s web panel, it’s probably using an ancient firmware version, and you should update it to the current one.
  • If Shelly devices are in a different subnet than the Home Assistant server, you should ensure communication on UDP port 5683 between these subnets.
  • If Home Assistant is running as a virtual machine or service on an operating system other than Home Assistant OS, you should open UDP port 5683 on the device’s firewall and/or ensure that communication from this port is redirected to the Home Assistant service.
  • The missing push updates may be related to the WiFi network range. If using a WiFi network with several access points, enable Internet & Security >> WiFi Client AP Roaming option. Consider moving Shelly device closer to the WiFi access point. Consider adding another WiFi access point, which will improve the connection quality with the device.
  • If you think your Shelly devices are working correctly and don’t want to change your network/configuration, you can ignore the repair issue. Still, you must know you are giving up the best experience of using first-generation Shelly devices with Home Assistant.

Shelly device configuration (generation 2 and 3)

Generation 2 and 3 devices use the RPC protocol to communicate with the integration. Battery operated devices (even if USB connected) need manual outbound WebSocket configuration, Navigate to the local IP address of your Shelly device, Settings >> Connectivity >> Outbound WebSocket and check the box Enable Outbound WebSocket, under server enter the following address:

ws:// + Home_Assistant_local_ip_address:Port + /api/shelly/ws (for example: ws://192.168.1.100:8123/api/shelly/ws), click Apply to save the settings. In case your installation is set up to use SSL encryption (HTTPS with certificate), an additional s needs to be added to the WebSocket protocol, too, so that it reads wss:// (for example: wss://192.168.1.100:8123/api/shelly/ws).

Note

Integration is communicating directly with the device; cloud connection is not needed.

Bluetooth Support

Shelly generation 2 and 3 devices not battery-powered can act as a Bluetooth proxy for advertisements. Active or passive listening can be enabled in the options flow.

Options

Options for Shelly can be set via the user interface, by taking the following steps:

  • Browse to your Home Assistant instance.
  • Go to Settings > Devices & Services.
  • If multiple instances of Shelly are configured, choose the instance you want to configure.
  • Select the integration, then select Configure.

Range Extender Support

Shelly generation 2 and 3 devices that are not battery-powered can act as a Range Extender. Devices of the same generations can be configured via those Range Extenders specifying a custom TCP port during the configuration flow. Currently, only static IP or DHCP reserved IP are supported for the main device.

Entity naming (generation 1)

The integration uses Device Name to name its entities if the device has only one relay or no relays at all.

The integration uses the following strategy to name its entities if the device has more than one relay:

  • If Device Name or Channel Name is set in the device, the integration will use them to generate the entities’ name.
  • If channel names are set, they will be used in the entity names. The device name will not be used.
  • If only the device name is set, and the device has multiple channels, the channel number will be appended to the entity name (e.g., Channel 2).
  • In case device name and channel names are not set, the entity name will be generated by the Device Type, Device ID and Channel Number.

Examples:

Device Name Channel Name Entity Name
Not set Not Set shellyswitch25-ABC123 Channel 1
Not set Kids Room Bulb Kids Room Bulb
Kitchen Not Set Kitchen Channel 1
Bedroom Round Bulb Round Bulb

Names are set from the device web page:

  • Device name can be set in Settings >> DEVICE NAME
  • Channel name for single-channel devices can be set in Settings >> CHANNEL NAME
  • Channel name for multi-channel devices can be set in Settings >> CHANNEL NAME after selecting the channel, by clicking on the channel name.

Entity naming (generation 2 and 3)

The integration uses the following strategy to name its entities:

  • If Channel Name is set in the device, the integration will use it to generate the entities’ name, e.g. Kitchen Light
  • If Channel Name is set to the default value, the integration will use the Device ID and default channel name to generate the entities’ name, e.g. ShellyPro4PM-9808D1D8B912 switch_0.

Binary input sensors

Binary input sensors (generation 1)

Depending on how a device’s button type is configured, the integration will create binary sensors corresponding to those inputs. binary sensors are not created when the button type is momentary or momentary_on_release, for these types you need to use events for your automations.

Binary input sensors (generation 2 and 3)

For generation 2 and 3 hardware it’s possible to select if a device’s input is connected to a button or a switch. Binary sensors are created only if the input mode is set to switch. When the input is of type button you need to use events for your automations.

Event entities (generation 1)

If the BUTTON TYPE of the switch connected to the device is set to momentary or detached switch, the integration creates an event entity for this switch. You can use this entity in your automations.

Event entities (generation 2 and 3)

If the Input Mode of the switch connected to the device is set to Button, the integration creates an event entity for this switch. You can use this entity in your automations.

Events

If the BUTTON TYPE of the switch connected to the device is set to momentary or detached switch, integration fires events under the type shelly.click when the switch is used. You can use these events in your automations.

Also, some devices do not add an entity for the button/switch. For example, the Shelly Button1 has only one entity for the battery level. It does not have an entity for the button itself. To trigger automations based on button presses, use the shelly.click event.

Listening for events

You can subscribe to the shelly.click event type in Developer Tools/Events in order to examine the event data JSON for the correct parameters to use in your automations. For example, shelly.click returns event data JSON similar to the following when you press the Shelly Button1.

Event 0 fired 9:53 AM:
{
    "event_type": "shelly.click",
    "data": {
        "device_id": "e09c64a22553484d804353ef97f6fcd6",
        "device": "shellybutton1-A4C12A45174",
        "channel": 1,
        "click_type": "single",
        "generation": 1
    },
    "origin": "LOCAL",
    "time_fired": "2021-04-28T08:53:12.755729+00:00",
    "context": {
        "id": "e0f379706563aaa0c2c1fda5174b5a0e",
        "parent_id": null,
        "user_id": null
    }
}

The generation value indicates the generation of the device that is the source of the event.

Automations

The simplest way to create automations is to use the Home Assistant automation editor. For example, to set an automation triggered by a double press of a particular Shelly Button1:

  1. In the Triggers section of the automation, set Trigger Type to Device.
  2. In the Device dropdown menu. find the Shelly Button1.
  3. In the Trigger dropdown menu, select Button double clicked.
  4. Set any conditions and actions to complete your automation.

You can also create automations using YAML, for example:

- alias: "Toggle living room light"
  trigger:
    platform: event
    event_type: shelly.click
    event_data:
      device: shellyswitch25-AABBCC
      channel: 1
      click_type: single
  action:
    service: light.toggle
    target:
      entity_id: light.living_room

- alias: "Toggle living room lamp"
  trigger:
    platform: event
    event_type: shelly.click
    event_data:
      device: shellyswitch25-AABBCC
      channel: 2
      click_type: long
  action:
    service: light.toggle
    target:
      entity_id: light.lamp_living_room

Possible values for click_type

Shelly input event Click Type
S single
SS double
SSS triple
L long
SL single_long
LS long_single

Generation 2 and 3 devices use the values btn_down, btn_up, single_push, double_push, triple_push and long_push as click_type.

Note

Not all devices support all input events. You can check on Shelly API Reference website what types of Shelly input events your device supports.

Appliance type (generation 1)

Shelly device relays are added to Home Assistant by default as switch entities. A relay can be added as a light entity if Settings >> APPLIANCE TYPE value is set to light.

Consumption type (generation 2 and 3)

Shelly device relays are added to Home Assistant by default as switch entities. A relay can be added as a light entity if EXTERNAL CONSUMPTION TYPE value is set to light.

Light transition

Shelly lights supporting light transition:

  • Shelly Bulb RGBW
  • Shelly DUO
  • Shelly Dimmer
  • Shelly Dimmer 2
  • Shelly RGBW2
  • Shelly Vintage

Note

The firmware limits the transition time to 5 seconds.

Device services

The integration offers device services which can be triggered by a configuration button.

OTA firmware update

Trigger device OTA firmware update.

Update entities

  • Firmware update
    • triggers the OTA firmware update process to the latest stable version
  • Beta firmware update (disabled by default)
    • triggers the OTA firmware update process to the latest beta version

Reboot

Trigger reboot of device.

Buttons

  • Reboot
    • triggers the reboot

Shelly Thermostatic Radiator Valve (TRV)

Shelly TRV generates 2 entities that can be used to control the device behavior: climate and number. The first will allow specifying a temperature, the second instead of a percentage of the valve position.

Note: that if you change the valve position then automatic temperature control will be disabled. As soon as you change the temperature, it gets enabled again.

Shelly Gas with Valve add-on

If you have the Valve add-on connected to Shelly Gas, the integration will create two entities for the valve. The valve entity allows you to control the valve, the sensor entity shows exact states of the valve.

CoAP port (generation 1)

In some cases, it may be needed to customize the CoAP UDP port (default: 5683) your Home Assistant instance is listening to.

In order to change it, add the following key to your configuration.yamlThe configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI.[Learn more]:

# Example configuration.yaml entry
shelly:
  coap_port: 12345

Additional info

Shelly devices rely on SNTP for features like power measurement. Please check from the device Web UI that the configured server is reachable.

Known issues and limitations

  • Only supports firmware 1.9 and later for generation 1 devices
  • Only supports firmware 1.0 and later for generation 2 devices
  • The following generation 1 devices only support firmware 1.11 and later (due to incompatible API):
    • Shelly DUO
    • Shelly Bulb RGBW
    • Shelly Dimmer
    • Shelly Dimmer 2
    • Shelly RGBW2
    • Shelly Vintage
  • Generation 1 “Shelly 4Pro” and “Shelly Sense” are not supported (devices based on old CoAP v1 protocol)
  • Before set up, battery-powered devices must be woken up by pressing the button on the device.
  • For battery-powered devices, the update platform entities only inform about the availability of firmware updates but are not able to trigger the update process.
  • Using the homeassistant.update_entity service for an entity belonging to a battery-powered device is not possible because most of the time these devices are sleeping (are offline).
