Å Energi is committed to a future based on renewable energies.
Enabling service providers to increase the effect and value of their services through detailed energy data is the primary goal of SmartEO, a solution developed by Å Energi. However, accessing reliable energy data from buildings at an affordable price is often challenging. This is where the Wattsense solution comes in.
SmartEO is hardware agnostic, and Wattsense is one of their preferred solutions as it provides access to energy data from existing infrastructures giving control to the SmartEO users.
Wattsense is a connectivity solution that enables the use of smart integrations, like SmartEO, to improve energy efficiency and building management.
SmartEO uses the Wattsense Bridge to connect ModBus, BacNet, and M-bus equipment in buildings with existing networks. Electricians install and configure the Bridge, which takes less than one day. The Bridge allows SmartEO to access energy data and use it as part of their solution.
The Wattsense Bridge is a multi-protocol product more powerful than a traditional gateway and created for on-premises building connectivity. Currently, 13 Bridges collect data for SmartEO.
“At SmartEO, we take responsibility for everything, including installation and maintenance, and make the experience smooth and hassle-free -contrary to the experience most clients in the property sector have today. ”Anders Diep-Lynne, Chief Commercial Officer at SmartEO by Å Energi.
SmartEO can be used by anyone that needs information about their energy consumption, most commonly to manage or monitor different aspects of buildings and for reporting. Users can measure and document their consumption with more details and more accurate precision. This enables them to make data-driven decisions and improvements with higher impact, detect errors and malfunction, and perfect the control of specific building functions.
Wattsense helps SmartEO by providing the data and insight needed to deliver its services. SmartEO uses available parameters from different types of meters and sensors, like power, flow, time, and temperatures, for quality assurance and data reconstruction capabilities and all energy sources, including electrical, thermal, gas, and water consumption. Figure 1 shows an example of electrical meters.

“With Wattsense, we gain valuable insight and control capabilities from a single Bridge. We don't need to install a lot of hardware to access the data required to make informed decisions about energy consumption. ”Anders Diep-Lynne, Chief Commercial Officer at SmartEO, by Å Energi.
For instance, using Wattsense, SmartEO extracted data from an energy meter and detected that it had been flatlined at ~500,000 kWh for more than 200 days (blue line, figure 2). Based on the measured power from the same meter (blue line, figure 3), SmartEO calculated and reconstructed actual energy consumption (orange line, figure 2) for the locked time period.

Using Wattsense, SmartEO can calculate consumption with high accuracy, correct data where there are errors, and even reconstruct data where it is missing. This example shows one of many principles used in SmartEO for data reconstruction and quality assurance.
