Highlights

Adaptive peak shaving

The platform now supports Adaptive Peak Shaving for Lewiz devices. Previously, users could only set a fixed maximum grid offtake target for peak-shaving applications. If household demand exceeded this target, the peak for the month remained unchanged. With Adaptive Peak Shaving, the system can now automatically adjust the target peak dynamically when high household demand occurs, ensuring more effective peak-shaving throughout the month.

To activate this feature, search for an installation and use the button Other Actions -> Enable adaptive peak shaving. This feature will also come to our dashboard so the end-users can choose to activate or deactivate this feature themselves.

Virtual meters

After months of experimentation, Virtual Meters are now ready for broader deployment. These meters calculate values derived from measured data, such as combining grid consumption, battery offtake, and PV production to determine total household consumption.

What’s New?

• Single Virtual Meter per Installation: Each installation now supports only one Virtual Meter. This change centralizes all calculated measurements, enabling dependencies between calculations to be resolved simultaneously and more efficiently.
• Dedicated Calculations Engine: A new, modular calculations engine has been introduced, allowing us to seamlessly add and manage additional calculated values as the system evolves.

What's next?

• Dashboard Improvements: The dashboard currently shows savings based on Virtual Meters, while self-consumption and total consumption are calculated on the fly, leading to occasional inconsistencies. To improve reliability and performance, the dashboard will transition to using the new calculations engine for all metrics, including self-consumption and total consumption.
• Extended EMS Savings calculations: EMS savings will be enhanced to account for actions taken by the Cloud EMS. This will provide a more comprehensive and accurate view of the savings achieved through automated energy management.

Other improvements

• Day-ahead prices (Belpex, APX) are now collected with an additional validation step to ensure all prices for the upcoming day are available. This enhancement guarantees the reliability of our Cloud EMS, even when price data is incomplete or delayed.
• The Cloud EMS now fully accommodates Daylight Savings Time changes. On DST transition days, the system adjusts to plan for the appropriate number of hours instead of assuming a fixed 24-hour schedule.
• A broad range of edge cases related to Smart EV Charging are now automatically tested and validated, ensuring improved reliability and robustness.
• Alarms will now be triggered for API Gateways (Fluvius and SolarEdge) in case of authorization errors. These alarms provide clear insights into issues with external API providers, facilitating faster troubleshooting.
• Addressed an issue where signal strength was missing during initial faulty SIM connections in Lewiz, causing unexplained connection test failures. The system now explicitly identifies and reports the underlying cause, improving diagnostics.
