Find closest entity: closest
The closest template function finds the 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] that is geographically closest to a given location. By default, it compares against your home location, but you can also specify coordinates or another entity as the reference point.
This is useful for location-based automationsAutomations in Home Assistant allow you to automatically respond to things that happen in and around your home. [Learn more]. For example, you could find out which family member is closest to home, which store is nearest to your current position, or which of your device trackers is closest to a specific zoneZones allow you to specify certain regions on a map. They enable zone presence-detection and can be used in automations. For example, to start the vacuum after you left home or start the heating at home when you leave the office. [Learn more]. The function returns a full state object, so you can access the entity’s name, state, attributes, and ID.
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 default are required.

Good to know
- Returns
Nonewhen no entity has usable GPS coordinates, so check before accessing.nameor other attributes. - Only entities with latitude and longitude attributes are considered. Entities without coordinates are silently skipped.
- Returns a full state object, not just an entity ID or name.

Show who is closest to home and their distance
Combine closest with distance to show both who is nearest and how far away they are.
{% set nearest = closest(states.person) %}
{{ nearest.name }} is closest at
{{ distance(nearest) | round(1) }} km away
Paulus is closest at 2.3 km away
