New updates and improvements
Release Notes - February
EV Charger Support
New EV Charger module: full support for EV chargers in the platform.
EV dashboard: new overview page with charging stations and connectors, real-time power, donut chart, and SoC column.
Charging priority: priority can be set per connector; changes are processed in a queue.
Integration: EV chargers included in the EMS dashboard (block) and in consumption planning.

EMS dashboard optimization
Consumption Planning
Interface to manually enter consumption planning.
Plan additional consumption as recurring. For example, for machines that switch on at fixed times where sufficient energy must be buffered to smooth this consumption peak.
Incidents and Monitoring
Muted incidents: incidents can be muted; muted incidents no longer count toward status/badges in the project overview.
New triggers: incident for negative consumption; command that verifies whether PV production is actually generating when it should.
Device Support and Management
New brands/models: Hite (PCS/BMS), Solis, Growatt, Socomec (energy meter), Schneider IEM3555 energy meter. Sunspec generic PV device; SCU BRES reverse PCS adapter; proxy for Gres BMS; Hite combiner box.
Adding devices: wizard redesigned:
Device properties are read live from the device.
Check if the device is reachable during setup.
Child devices are detected and offered for automatic addition (e.g., hybrid inverters).
Support for multiple BMS devices per inverter.
Improved validation and device configuration.
MCP (Model Context Protocol)
MCP server: new MCP server with device search and resources. Currently in beta.
Strategy and Trading
Project strategy: deadband as a project strategy setting.
Minor Adjustments and Improvements
UI/UX: small design and padding fixes; horizontal scrolling on battery components (no mouse wheel); fixed scrolling in charts; copy-to-clipboard for hardware ID (HTTPS); phone number no longer required/unique in profile.
Forms: improvements to General Settings, add device form, and user profile (including precognition, password saving); tooltips and visibility logic in device settings.
Charts: hidden series filtered from tooltip; tooltip rendering fixed when first series is disabled; minimum y-axis set to 0; adjusted line width; check added when chart element is not found (no mount).
