Get config entry attribute: config_entry_attr
The config_entry_attr template function returns a specific attribute from a config entry, identified by its config entry ID. You can retrieve attributes like domain, title, state, source, disabled_by, and pref_disable_polling. It returns None if the config entry does not exist.
This is useful for inspecting the configuration behind your entitiesAn entity represents a sensor, actor, or function in Home Assistant. Entities are used to monitor physical properties or to control other entities. An entity is usually part of a device or a service. [Learn more]. For example, you might want to check if a config entry is still loaded and working, find out which integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] domain it belongs to, or display the title of the config entry in a notificationYou can use notifications to send messages, pictures, and more, to devices. [Learn more]. Combined with config_entry_id, you can trace any entity back to its config entry and read details about it.

Function signature
The signature is a technical summary of this template function. It shows the name of the function, the values (called parameters) it accepts, and what type of data each parameter expects (for example, a piece of text or a number).
Function parameters that have a = with a value after them are optional. If you leave them out, the default value shown is used automatically.
Function parameters without a = are usually required. A few optional parameters have no default value, so the signature shows them without a = as well. To check whether a parameter is required, look at the parameter list below the signature. Each parameter is marked as Required or Optional.
The most common optional parameter without a default value is default. The default parameter sets the value a function returns when the function can’t produce a result, for example, when float gets text that isn’t a number. If you leave out default, there is no fallback value, so most functions raise an error and the template fails. The parameter list of each function says what happens. If you set default, the function returns your value instead.
How to read a signature
Here is the signature of the round filter as an example:
round(
value: Any,
precision: int = 0,
method: str = "common",
default: Any,
) -> float | int | Any
-
roundis the name of the function. - Between the parentheses are the parameters. Each parameter has a name, followed by a colon and the type of value the parameter expects. The type only tells you what kind of value to pass. For
default: Any, you pass a value of any type, such as0or"unknown", not the wordAny. -
= 0and= "common"are default values. You can leave outprecisionandmethod, androunduses these default values. -
defaulthas no=, but the parameter list marksdefaultas optional. If you leave outdefaultandroundgets a value that isn’t a number,roundraises an error. -
->shows the type of value the function returns. - Inside a signature,
|means “or”. This function returns a decimal number, a whole number, or the value you passed asdefault.
round is a filter, so the first parameter, value, is the value before the |. For example, {{ 3.14159 | round(2) }} returns 3.14.
The types you’ll see most often:
-
str: text, such as"hello" -
int: a whole number, such as5 -
float: a decimal number, such as3.14 -
bool:trueorfalse -
list: a list of values, such as[1, 2, 3].list[str]is a list of texts. -
dict: a set of keys and values, such as{"name": "Kitchen"} -
datetimeandtimedelta: a date and time, and a duration. For details, refer to Dates and times. -
None: no value -
Any: any type of value
Some signatures use special forms:
-
*argsmeans you can pass any number of values, separated by commas. For example,average(1, 2, 3). -
value | name(...)means the function is a filter. The value before the|is passed to the filter as its first parameter. Some filter signatures, like theroundexample, show this value as the first parameter between the parentheses instead.

Function parameters
The following parameters can be provided to this function.
The config entry ID to look up. You can get this from config_entry_id.
Available attributes
The following attributes can be retrieved from a config entry:
-
domain: The integration domain (for example,hue,zwave_js). -
title: The user-defined title of the config entry. -
state: The current state of the config entry (for example,loaded,setup_error,not_loaded). -
source: How the config entry was created (for example,user,discovery). -
disabled_by: Why the config entry is disabled, orNoneif it is not disabled. -
pref_disable_polling: Whether polling has been disabled for this config entry.
Good to know
- Returns
Nonewhen the config entry does not exist. - Only the fixed attribute names listed above are allowed. Any other attribute name causes the error Invalid config entry attribute, even if the config entry doesn’t exist.
- The config entry ID must be text. If it’s
None, the template fails with the error Must provide a config entry ID. This happens, for example, when you pass the result ofconfig_entry_idfor an entity that you set up in YAML, because that entity has no config entry. - The input is the config entry ID, not an entity ID. Resolve from an entity with
config_entry_idfirst.
