title: Changes in setup entity platforms with group integration
---
## Changes in setup entity platforms with group integration
By default, the `group` integration allows entities to be grouped. If the default `ON`/`OFF` states for an entity default to `on` and `off`, then `grouping` is supported by default. The setup changes, though, for Entity platforms that can be grouped but have alternative states, e.g., `cover` (`open`/`closed`) or `person` (`home`/`not_home`), or platforms that are meant to be excluded, such as `sensor`. These entity platforms must implement `async_describe_on_off_states` in the `group.py` module.
In `async_describe_on_off_states`, the `domain` needs to be the first argument passed to the `registry` methods `on_off_states` and `exclude_domain`. When registering alternative `ON`/`OFF` states with `registry.on_off_state`, in addition to the `ON` states, the default `ON` state needs to be passed.
### Example registering alternative states
New signature for `registry.on_off_states`:
```python
@callback
def on_off_states(
self, domain: str, on_states: set[str], default_on_state:str, off_state: str
) -> None:
"""Register on and off states for the current domain."""
...
```
Example `group.py` for the `vacuum` entity platform registering alternative `ON`/`OFF` states. Note the the first `ON` state now is considered to be the default `ON` state.
```python
"""Describe group states."""
from typing import TYPE_CHECKING
from homeassistant.const import STATE_OFF, STATE_ON
from homeassistant.core import HomeAssistant, callback
if TYPE_CHECKING:
from homeassistant.components.group import GroupIntegrationRegistry
from .const import DOMAIN, STATE_CLEANING, STATE_ERROR, STATE_RETURNING
@callback
def async_describe_on_off_states(
hass: HomeAssistant, registry: "GroupIntegrationRegistry"
) -> None:
"""Describe group on off states."""
registry.on_off_states(
DOMAIN, # domain
# set with all group ON states
{
STATE_ON,
STATE_CLEANING,
STATE_RETURNING,
STATE_ERROR,
},
STATE_ON, # Default group ON state
STATE_OFF, # Group OFF state
)
```
### Example excluding an entity platform from group entities
New signature for `registry.exclude_domain`:
```python
@callback
def exclude_domain(self, domain: str) -> None:
"""Exclude the current domain."""
...
```
Example `group.py` for the `sensor` entity platform to exclude sensor entities from `group` entities.
```python
"""Describe group states."""
from typing import TYPE_CHECKING
from homeassistant.core import HomeAssistant, callback
if TYPE_CHECKING:
from homeassistant.components.group import GroupIntegrationRegistry
from .const import DOMAIN
@callback
def async_describe_on_off_states(
hass: HomeAssistant, registry: "GroupIntegrationRegistry"
) -> None:
"""Describe group on off states."""
registry.exclude_domain(DOMAIN)
```
