Availability *Availability `json:"availability,omitempty"`
// The MQTT topic subscribed to receive availability (online/offline) updates. Must not be used together with availability.
AvailabilityTopic String `json:"availability_topic,omitempty"`
// When availability is configured, this controls the conditions needed to set the entity to available. Valid entries are all, any, and latest. If set to all, payload_available must be received on all configured availability topics before the entity is marked as online. If set to any, payload_available must be received on at least one configured availability topic before the entity is marked as online. If set to latest, the last payload_available or payload_not_available received on any configured availability topic controls the availability.
AvailabilityMode String `json:"availability_mode,omitempty" default:"latest"`
// Defines a template to extract device’s availability from the availability_topic. To determine the devices’s availability result of this template will be compared to payload_available and payload_not_available.
AvailabilityTemplate Template `json:"availability_template,omitempty"`
// Defines a template to generate the payload to send to command_topic.
CommandTemplate Template `json:"command_template,omitempty"`
// The MQTT topic to publish commands to change the selected option.
CommandTopic String `json:"command_topic,omitempty" required:"true"`
// Information about the device this Select is a part of to tie it into the device registry. Only works through MQTT discovery and when unique_id is set. At least one of identifiers or connections must be present to identify the device.
Device Device `json:"device,omitempty"`
// Flag which defines if the entity should be enabled when first added.
EnabledByDefault Boolean `json:"enabled_by_default,omitempty" default:"true"`
// The encoding of the payloads received and published messages. Set to "" to disable decoding of incoming payload.
Encoding String `json:"encoding,omitempty" default:"utf"`
// The category of the entity.
EntityCategory String `json:"entity_category,omitempty" default:"None"`
// Icon for the entity.
Icon Icon `json:"icon,omitempty"`
// Defines a template to extract the JSON dictionary from messages received on the json_attributes_topic.
JsonAttributesTemplate Template `json:"json_attributes_template,omitempty"`
// The MQTT topic subscribed to receive a JSON dictionary payload and then set as entity attributes. Implies force_update of the current select state when a message is received on this topic.
JsonAttributesTopic String `json:"json_attributes_topic,omitempty"`
// The name of the Select.
Name String `json:"name,omitempty"`
// Used instead of name for automatic generation of entity_id
ObjectId String `json:"object_id,omitempty"`
// Flag that defines if the select works in optimistic mode.
Optimistic Boolean `json:"optimistic,omitempty"`
// Default: true if no state_topic defined, else false.
// List of options that can be selected. An empty list or a list with a single item is allowed.
Options List `json:"options,omitempty" required:"true"`
// The maximum QoS level of the state topic. Default is 0 and will also be used to publishing messages.
Qos Integer `json:"qos,omitempty" default:"0"`
// If the published message should have the retain flag on or not.
Retain Boolean `json:"retain,omitempty" default:"false"`
// The MQTT topic subscribed to receive update of the selected option.
StateTopic String `json:"state_topic,omitempty"`
// An ID that uniquely identifies this Select. If two Selects have the same unique ID Home Assistant will raise an exception.
UniqueId String `json:"unique_id,omitempty"`
// Defines a template to extract the value.
ValueTemplate Template `json:"value_template,omitempty"`
