custom_event — Home Assistant service to fire events

This component creates custom_event.fire service in Home Assistant which can be used to fire any event. This service may be used when it's not possible to fire event using other built-in ways. Several examples:

• fire event when button in Lovelace was pressed
• fire event when action happened with template entity (template switch, template cover, universal media player, etc.)

Installation

1. Add https://github.com/andreypolyak/hass_custom_event as custom repository in HACS
2. Install custom_event custom component in HACS
3. Add custom_event: to configuration.yaml file in Home Assistant

Usage

custom_event.fire service has two data attributes:

Attribute name	Optional	Description
event_type	No	Event type
event_data	Yes	Dictionary which will be passed as data to event
