Smart metering is a key feature of a smart city and is developing fast globally. On the other hand, there is no common communication standard, and systems from different manufacturers are incompatible in Hong Kong. This project aims to develop a smart water meter communication standard and its reference design for the demanding environment of Hong Kong's water supplies system. An open Hong Kong Smart Water Meter Communication Standard will be drafted, such that equipment and software from different smart water meter manufacturers can work seamlessly and be integrated into WSD (Water Supplied Department)’s system. A reference design will be built to provide a low-energy smart water meter platform to new and existing buildings. This project focuses on the development of a smart water meter communication standard (technical, communication, security, inspection and data storage standards) and its reference platform (meter interface unit, data concentration unit, LoRa low-power star network and cloud platform). This project enables commercial manufacturers to build, develop, and deploy an automatic water meter reading system to Hong Kong’s water supplies system.
