A strong release for e-mobility and dynamic tariffs. Three new wallboxes — Ambibox ambiCHARGE Home, Voltie AC (contributed by Voltie themselves!) and Mennekes Professional — plus a new grouped overview for charge-point clusters. Electricity spot prices can now be fetched from multiple providers, including via your own Backend. And the UI is now available in Lithuanian and Swedish, with all other translations completed.
Highlights
- Wallboxes: Ambibox ambiCHARGE Home, Voltie AC, Mennekes Professional; Alfen NG9xx with full app & UI
- Dynamic tariffs: spot prices from multiple providers, optionally via your own Backend; legacy ENTSO-E components migrated to the spot-tariff system
- New devices: Shelly Plug M Gen3, Janitza grid meter via Modbus/RTU, Jumo HydroTrans S20, Blue E Plus & Hydac cooling units, Hekatron B9-X2 fire alarm
- Notable fix: SMA Sunny Island multi-device power control (three-phase systems previously discharged 3× the requested power); -11 generation now supported
- UI: charge-point cluster overview, Energy Scheduler v2 with live notifications, grid charge/discharge permissions page
Energy Scheduler v1 has been removed — v2 is now the only version
