After the renovation
A long-term investment. An open choice of platform.
For Tartu mnt 52 apartment association in Iisaku, Alutaguse municipality, completing a full renovation raised the next question: how should the building’s water and energy data be managed?
The association wanted to see consumption hour by hour and use equipment from different manufacturers. It also wanted to avoid a ten-year service commitment. The platform had to fit the building’s needs today and leave room for new sensors, meters and solutions later.
The installation
Different devices. One view of consumption.
Lobaro wM-Bus gateways receive readings from the Apator water meters and Siemens heat cost allocators. Divako brings these devices into one platform, giving the association an hourly consumption overview and access through the Divako mobile app.
- Apator water meters with NAXOM OP-04-1a radio modules
- Siemens WHE542-0001S heat cost allocators
- Two-sensor configuration · wM-Bus S1 mode
- Allocator annual reference date: 31 December

In the customer’s words
“Divako lets us see all the information about the building’s water and energy consumption exactly as we want. Technical support is always available and helps with any question related to accessing the data.”
Why Divako
The freedom to keep choosing.
Vendor independence was central to the decision. Apator meters, Siemens allocators and Lobaro gateways already work together in this installation. The association can choose equipment from different manufacturers and extend its setup as its needs change.
The commercial model mattered too. Divako’s pay-as-you-go approach lets the association use the service while it pays for it, without a long-term contract. Combined with accessible data and technical support, that made Divako a fit for life after the renovation.
