Shelly


Integrate Shelly devices into Home Assistant.

Shelly device configuration

Shelly devices use the CoIoT protocol to communicate with integration. For Shelly firmware 1.10.0 or newer, 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 Shelly Motion with firmware 1.1.0 or newer. After changing the CoIoT peer, the Shelly device needs to be manually restarted.

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

Configuration

Adding Shelly to your Home Assistant instance can be done via the user interface, by using this My button:

Shelly can be auto-discovered by Home Assistant. If an instance was found, it will be shown as “Discovered”, which you can select to set it up right away.

Manual configuration steps

Entity naming

The integration uses the following strategy to name its entities:

  • 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.

Appliance type

Shelly device relays are added to the Home Assistant by default as switch entities. A relay can be added as a light entity if the device uses firmware version 1.9.0 or newer and the Settings >> APPLIANCE TYPE value is set to light.

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"
    },
    "origin": "LOCAL",
    "time_fired": "2021-04-28T08:53:12.755729+00:00",
    "context": {
        "id": "e0f379706563aaa0c2c1fda5174b5a0e",
        "parent_id": null,
        "user_id": null
    }
}

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

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

CoAP port

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

In order to change it, add the following key to your configuration.yaml:

# Example configuration.yaml entry
shelly:
  coap_port: 12345

Known issues and limitations

  • Only supports firmware 1.8 and later
  • 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.
