Get entities with a label: label_entities
The label_entities template function returns a list of entityAn 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] IDs that have a specific labelLabels in Home Assistant allow grouping elements irrespective of their physical location or type. Labels can be assigned to areas, devices, entities, automations, scenes, scripts, and helpers. Labels can be used in automations and scripts as a target for actions. Labels can also be used to filter data. [Learn more] assigned. You can specify the label by its name or by its internal ID. This gives you all entities tagged with that label.
This is useful when you want to act on a group of entities that share a common label, regardless of which areaAn area in Home Assistant is a logical grouping of devices and entities that represents a room or space in your home, such as the living room, kitchen, or garage. [Learn more] or deviceA device is a model representing a physical or logical unit that contains entities. they belong to. For example, if you label certain sensors as “Critical”, you could use label_entities to monitor all of them at once, or if you label energy-related entities as “Energy Monitoring”, you could build a dashboard that automatically includes every labeled entity. As you add or remove labels from entities, the list automatically updates, so your automationsAutomations in Home Assistant allow you to automatically respond to things that happen in and around your home. [Learn more] and templatesA template is an automation definition that can include variables for the action or data from the trigger values. This allows automations to generate dynamic actions.

Automation actions can target entities by label through the visual editor, no template needed. Reach for label_entities() when you need to loop over or filter the entities inside a template expression.
Usage

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.
label_entities(
label_id_or_name: str,
) -> list[str]
Function parameters
The following parameters can be provided to this function.
The label name or ID to look up. Returns the entity IDs that have this label assigned. You can find labels in Settings > Areas, labels & zones.
Good to know
- Only returns entities with the label assigned directly. Labels applied to devices or areas do not roll up to their entities.
- Returns an empty list when the label does not match any entities.
- Uppercase and lowercase letters and spaces in a label name don’t matter. A label ID must match exactly.
