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.

	CommandTopic String `json:"command_topic,omitempty"`

When a JSON payload is detected, the state value of the JSON payload should supply the installed_version and can optional supply: latest_version, title, release_summary, release_url or an entity_picture URL.

	// Title of the software, or firmware update. This helps to differentiate between the device or entity name versus the title of the software installed.
	Title String `json:"title,omitempty"`
