Smart M-Bus can incorporate M-Bus disconnect module which, can isolate the heat interface unit (HIU) to eliminate debt risk. When combined with the Boble app, this is transformed into a pay-as-you-go system that allows users to view their current supply status and available credit. Users can also make payments through the app. Network performance monitoring can be easily performed by using Kamstrup consumer and system energy meters. In addition to standard metering data, the meters can also measure volume weighted average flow temperatures (VWAFT) and volume weighted average return temperatures (VWART), as well as Coefficient of Performance (COP). Maximum power and flow readings are also recorded to help monitor peak loads.
