July 2025 Update

Data quality when replacing devices

To further improve evaluation and visualisation, implausible performance values are now automatically filtered during readout. This affects the following devices:

• SOLARWATT Inverter vision three and one
• Sunspec-compatible inverters (e.g. Kostal, Kaco, Fronius)
• SOLARWATT Meter vision (CHINT) energy meters

Changes & new functionality

EM.setup: Location as a separate step

The entry of the system location has been removed from the PV plants step and moved to the beginning of the setup process. If a location already exists, the step is automatically skipped. The location now appears as a separate module in the summary.

EM.setup: Adapted setup process for consumption-only installation

If only consumers are installed, the setup process skips the PV plants and home consumption steps. These steps are marked as incomplete, but not as incorrect.

EM.setup: Summary for consumption-only installations

For installations without PV plants, the Energy overview, PV plants and Test curtailment modules are hidden in the summary to ensure a clear display.

New compatibilities

SOLARWATT Charger max

Support for the SOLARWATT Charger max has been added (without phase switching - support for this will be added in a future release)

Bug fixes & stability

Optimisation time window

An error in the optimisation stack has been corrected where end timestamps at midnight were not correctly detected on the gateway. This was an important prerequisite for eliminating user-relevant errors in daily operations.

SOLARWATT Inverter vision one

The display of the charge level (State of Charge) was incorrect. This error has been corrected so that the current status is now displayed correctly.

Stiebel Eltron ISG

After a firmware update, some heat pumps no longer read performance values correctly. The new bugfix recognises and supports both the old and the new register layout. This also fixes the incorrect display with several devices.
