Automated reading

Submetering is the process of collecting consumption and condition data from individual user units in multi-tenant properties and using this data for billing purposes. While this market has been dominated by large metering service providers in the past, new regulation and technologies offer opportunities for emerging market players. We can help you tap into this lucrative market.

Developing new business areas

Individual consumption billing is now mandatory for landlords. For this purpose, the individual consumption of each rental unit is determined via heat cost allocators and hot water meters, so-called submeters. According to §5 HeizkostenV, these submeters must be remotely readable for new installations and replacements from December 2021. Manufacturer-independent radio solutions are prescribed for this purpose. This means that LoRaWAN®-capable submeters can also be used. With the help of their own LoRaWAN® network, municipal utilities can expand their service portfolio, which can then be used not only for remote reading of the house connection, but also for submetering within the flats.

HKVO-compliant remote reading with SK-Soft

Through PHYSEC's IoT service platform IoTree®, consumption data can be fed into a billing software and transmitted to the homeowner. This can ideally be implemented with PROHKA from SK-Soft, where the values are now checked and evaluated, and made available to the municipal utility or end user for review. The remote reading of the submeter readings is fully automatic, so that no additional personnel is required and no errors can occur during the reading. Readings are taken automatically at regular intervals and are accurate to the reporting date.
