• A subscription request for one or more Items. In this case, it is sent as an asyncronous notification to the involved listeners.
• The Updates flow for a single Item or all Items. In this case, it is sent as an asyncronous notification to the involved listeners.
• The connection status. In this case, it is sent as an asyncronous notification to the connection state listener.
