Functions

func FormatID 

func FormatID(s string) string

FormatID will take a string s and format it as snake_case. The new string is then an appropriate format to be used as a unique ID in Home Assistant.

func FormatName 

func FormatName(s string) string

FormatName will take a string s and format it with appropriate spacing between words and capitalised the first letter of each word. For example someString becomes Some String. The new string is then an appropriate format to be used as a name in Home Assistant.

func MarshalConfig 

func MarshalConfig(e *EntityConfig) (*mqtt.Msg, error)

MarshalConfig will marshal a config message and payload from the given EntityConfig.

func MarshalState 

func MarshalState(e *EntityConfig) (*mqtt.Msg, error)

MarshalState will marshal a state message and payload from the given EntityConfig and state value. Where an entity state is combined with other entities, it might be better to manually create a state message.

func MarshalSubscription 

func MarshalSubscription(e *EntityConfig) (*mqtt.Subscription, error)

MarshalState will marshal a subscription from the given EntityConfig.

func PublishConfigs 

func PublishConfigs(device MQTTDevice, client MQTTClient) error

func PublishState 

func PublishState(device MQTTDevice, client MQTTClient) error

func Register 

func Register(device MQTTDevice, client MQTTClient) error

Register will check if the app has been registered and if not, publish the app configs to MQTT, which will in turn register the app with Home Assistant. If successfully registered, it will also record this status in the app configuration. If any of these actions are unsuccessful, it will return an error with more details. Otherwise it returns nil.

func Subscribe 

func Subscribe(device MQTTDevice, client MQTTClient) error

func UnRegister 

func UnRegister(device MQTTDevice, client MQTTClient) error

UnRegister performs two actions. First, it removes the app config topics from MQTT, effectively removing the app from Home Assistant. Second, it updates the app config to indicate it is unregistered. It will return an error if either action fails, otherwise it will return nil.

func Unpublish 

func Unpublish(device MQTTDevice, client MQTTClient) error

}

type EntityConfig 

type EntityConfig struct {
	Entity             *Entity
	App                string
	CommandCallback    func(MQTT.Client, MQTT.Message)
	StateCallback      func() (json.RawMessage, error)
	AttributesCallback func() (json.RawMessage, error)
	ConfigTopic        string
	// contains filtered or unexported fields
}

func NewEntityByID 

func NewEntityByID(id, app string) *EntityConfig

NewEntityByID will create a new entity and config based off the given id and app. Use this when you want to ensure the exact format of the id for the underlying sensor in Home Assistant. The name will be derived from the id.

func NewEntityByName 

func NewEntityByName(name, app string) *EntityConfig

NewEntityByName will create a new entity and config based off the given name and app. Use this function where you don't care about the id of the underlying sensor in Home Assistant. The id will be derived from the name by converting it to snake_case.

func (*EntityConfig) AsBinarySensor 

func (e *EntityConfig) AsBinarySensor() *EntityConfig

AsBinarySensor will configure appropriate MQTT topics to represent a Home Assistant binary_sensor.

func (*EntityConfig) AsButton 

func (e *EntityConfig) AsButton() *EntityConfig

AsButton will configure appropriate MQTT topics to represent a Home Assistant button.

func (*EntityConfig) AsSensor 

func (e *EntityConfig) AsSensor() *EntityConfig

AsSensor will configure appropriate MQTT topics to represent a Home Assistant sensor.

func (*EntityConfig) WithAttributesCallback 

func (e *EntityConfig) WithAttributesCallback(c func() (json.RawMessage, error)) *EntityConfig

WithAttributesCallback will add the passed in function as the callback action to be run whenever the attributes of the entity are needed. If this callback is to be used, then the WithAttributesTopic() builder function should also be called to set-up the attributes topic.

func (*EntityConfig) WithAttributesTemplate 

func (e *EntityConfig) WithAttributesTemplate(t string) *EntityConfig

WithAttributesTemplate configures the passed in template to be used to extract the value of the attributes in Home Assistant.

func (*EntityConfig) WithAttributesTopic 

func (e *EntityConfig) WithAttributesTopic() *EntityConfig

WithAttributes ensures that the entity has a topic that can be used to publish its attributes.

func (*EntityConfig) WithCommandCallback 

func (e *EntityConfig) WithCommandCallback(c func(MQTT.Client, MQTT.Message)) *EntityConfig

WithCommandCallback will add the passed in function as the callback action to be run when a message is received on the command topic of the entity. It doesn't make sense to add this for entities that don't have a command topic, like regular sensors.

func (*EntityConfig) WithDefaultOriginInfo 

func (e *EntityConfig) WithDefaultOriginInfo() *EntityConfig

WithOriginInfo adds a pre-filled origin that references go-hass-agent to the entity config.

func (*EntityConfig) WithDeviceClass 

func (e *EntityConfig) WithDeviceClass(d string) *EntityConfig

WithDeviceClass configures the Device Class for the entity.

func (*EntityConfig) WithDeviceInfo 

func (e *EntityConfig) WithDeviceInfo(d *Device) *EntityConfig

WithDeviceInfo adds the passed in device info to the entity config.

func (*EntityConfig) WithIcon 

func (e *EntityConfig) WithIcon(i string) *EntityConfig

WithIcon adds an icon to the entity

func (*EntityConfig) WithOriginInfo 

func (e *EntityConfig) WithOriginInfo(o *Origin) *EntityConfig

WithOriginInfo adds the passed in origin info to the entity config.

func (*EntityConfig) WithStateCallback 

func (e *EntityConfig) WithStateCallback(c func() (json.RawMessage, error)) *EntityConfig

WithStateCallback will add the passed in function as the callback action to be run whenever the state of the entity is needed. It doesn't make sense to add this for entities that don't report a state, like buttons. It might not be useful to use this where you have a single state that represents many entities. In such cases, it would be better to manually send the state in your own code.

func (*EntityConfig) WithStateClassMeasurement 

func (e *EntityConfig) WithStateClassMeasurement() *EntityConfig

WithStateClassMeasurement configures the State Class for the entity to be "measurement".

func (*EntityConfig) WithStateClassTotal 

func (e *EntityConfig) WithStateClassTotal() *EntityConfig

WithStateClassMeasurement configures the State Class for the entity to be "total".

func (*EntityConfig) WithStateClassTotalIncreasing 

func (e *EntityConfig) WithStateClassTotalIncreasing() *EntityConfig

WithStateClassMeasurement configures the State Class for the entity to be "total_increasing".

func (*EntityConfig) WithUnits 

func (e *EntityConfig) WithUnits(u string) *EntityConfig

WithUnits adds a unit of measurement to the entity.

func (*EntityConfig) WithValueTemplate 

func (e *EntityConfig) WithValueTemplate(t string) *EntityConfig

WithValueTemplate configures the passed in template to be used to extract the value of the entity in Home Assistant.
