Geo Location aware entities are typically related to events in the real world in the vicinity of Home Assistant's location, like for example weather events, bush fires or earthquakes.
|
|
|
|
Entities can have associated geo location coordinates (latitude and longitude) so that they are displayed on the map. The distance from the entity's coordinates to Home Assistant's location can be used for filtering.

## {% linkable_title Geo Location trigger %}
|
|
|
|
The [Geo Location trigger](/docs/automation/trigger/#geo-location-trigger) can be used in automations triggered by Geo Location entities appearing in or disappearing from zones. The following value must be used as `source` of the trigger depending on which platform is managing the entities:
|
|
|
|
| Platform | Source |
|
|
|----------------------------------|-------------------------------|
|
|
| GeoJSON Events | `geo_json_events` |
|
|
| NSW Rural Fire Service Incidents | `nsw_rural_fire_service_feed` |
|
|
|
|
Conditions can be used to further filter entities, for example by inspecting their state attributes.
|
|
|
|
## {% linkable_title Geo Location notification example %}
|
|
|
|
The following example automation creates a notification on the screen when a fire classified as 'Bush Fire' is reported within a predefined bush fire alert zone:
|
|
|
|
{% raw %}
|
|
```yaml
|
|
geo_location:
|
|
- platform: nsw_rural_fire_service_feed
|
|
categories:
|
|
- 'Emergency Warning'
|
|
- 'Watch and Act'
|
|
- 'Advice'
|
|
|
|
zone:
|
|
- name: Bush Fire Alert Zone
|
|
latitude: -36.666667
|
|
longitude: 149.833333
|
|
radius: 15000
|
|
passive: true
|
|
|
|
automation:
|
|
- alias: 'Bush Fire Alert'
|
|
trigger:
|
|
platform: geo_location
|
|
source: nsw_rural_fire_service_feed
|
|
zone: zone.bush_fire_alert_zone
|
|
event: enter
|
|
condition:
|
|
condition: template
|
|
value_template: "{{ trigger.to_state.attributes.type == 'Bush Fire' }}"
|
|
action:
|
|
- service: persistent_notification.create
|
|
data_template:
|
|
message: "{{ trigger.to_state.name }} - {{ trigger.to_state.attributes.status }}"
|
|
title: "Bush Fire Alert"
|
|
```
|
|
{% endraw %}
