RabbitMQ Group Availability

RabbitMQ Group Availability API is capable of sending updates about parking occupancy with a calculated summary. When you use this API, you are getting complete occupancy info about parking. Nwave cloud calculates the number of occupied and vacant spaces according to parking type, parking sensors health and other secondary data.
