openHAB

Module: OpenHAB::Core::Things::Thing

Defined in:
lib/openhab/core/things/thing.rb

Overview

A Thing is a representation of a connected part (e.g. physical device or cloud service) from the real world. It contains a list of Channels, which can be bound to Items.

Examples:

thing = things["chromecast:audiogroup:dd9f8622-eee-4eaf-b33f-cdcdcdeee001121"]
logger.info("Audiogroup Status: #{thing&.status}")
logger.info("Audiogroup Online? #{thing&.online?}")
logger.info("Channel ids: #{thing.channels.map(&:uid)}")
logger.info("Items linked to volume channel: #{thing.channels['volume']&.items&.map(&:name)&.join(', ')}")
logger.info("Item linked to volume channel: #{thing.channels['volume']&.item&.name}")

Thing actions can be called directly through a Thing object

things["mqtt:broker:mosquitto"].publish_mqtt("zigbee2mqttt/bridge/config/permit_join", "true")
things["mail:smtp:local"].send_mail("me@example.com", "Subject", "Email body")

Thing can be accessed directly through entity lookup

# replace ':' with '_' in thing uid
mqtt_broker_mosquitto.online? # is mqtt:broker:mosquitto thing online?

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *args, &block) ⇒ Object

Delegate missing methods to the thing's default actions scope.

Examples:

things['mail:smtp:local'].send_email('me@example.com', 'subject', 'message')

Instance Method Details

#actions(scope = nil) ⇒ Object?

Fetches the actions available for this thing.

Default scope actions are available directly on the thing object, via #method_missing.

Examples:

things["max:thermostat:mybridge:thermostat"].actions("max-devices").delete_from_cube
things['mail:smtp:local'].send_email('me@example.com', 'subject', 'message')

Parameters:

  • scope (String, nil) (defaults to: nil) —

    The action scope. Default's to the thing's binding.

Returns:

  • (Object, nil)

def actions(scope = nil)
  $actions.get(scope || uid.binding_id, uid.to_s)
end

#config_eql?(other) ⇒ true, false

Compares all attributes of the thing with another thing.

Parameters:

  • other (Thing) —

    The thing to compare with

Returns:

  • (true, false) —

    true if all attributes are equal, false otherwise
