Residential building in Prague monitors energy consumption via M-Bus with Perseus Energy 285 and SensDesk Technology, CS07

A residential building in one of Prague's districts, managed by a condominium association, was looking for a solution to remotely monitor energy consumption in all 20 apartments and common areas.

The individual energy consumption data, as well as the energy consumption in the common areas of the residential building, together with the total consumption of the building, had to be individually accessible to the respective apartment owners or tenants in order to protect their privacy.

To solve such a problem intelligently, our distributor for the Czech Republic and Slovakia - HW server - came up with a solution based on a single Perseus Energy 285. A combined connectivity (LTE & LAN) monitoring device is installed in an electrical switchboard and connected to 23 M-Bus electricity meters - 20 for the apartments and an additional three for common areas.

The data collected by Perseus Energy 285 is then sent as variables to a single account at HWportal.cz - a portal based on SensDesk Technology. The Perseus operator can choose which variables to send to the portal - either all at once or individually.

One HWportal account can have one or more teams with different permission settings. In this particular scenario, an individual user account has been created for each apartment owner/tenant, which is part of the team, but with different permissions.

This makes it possible to manage the visibility of electricity meters for individual users, without each user being able to see their neighbour's data. The team administrator - a person who manages the community of owners - can see all the data at once.

In addition, a monthly electricity consumption report is automatically sent from the HW portal to the responsible person, in this case - the team administrator. The beauty of the monthly reports is that they clearly show the monthly changes - extracting the previous consumption from the current reading at the end of the month, showing only the difference in consumption that has occurred.

In this way, a single Perseus Energy 285 combined with the SensDesk Technology-based portal provides complete metering, monitoring and reporting of electricity consumption for the entire apartment building in Prague.
