v0.7.0

Another big release. It adds support for ha-evcc's new on-demand WebSocket data API, which lets the card read tariff forecasts, the full charging-session history and a live charging-plan preview straight from evcc without any extra Home Assistant entities, recorder load or helper sensors.

New features

• Live charging-plan preview (planner graph). In plan mode, as soon as you pick a target SoC and a departure time, the card shows a live preview of the planned charging window over the upcoming tariff/forecast, together with the expected duration, charging power and the average price or CO₂ of the plan. The preview updates while you drag the slider and is debounced and cached so it never floods evcc with requests.

• Statistics powered by your charging sessions. The stats mode is now fed directly by evcc's charging-session history through the new API, so it no longer needs the manually configured stat_* template/helper sensors or a recorder setup. The header mirrors evcc's own statistics view:
  • Period: Month, Year or Total, each with its own back/forward stepper to pick the exact month and year.
  • Metric: switch the bars between Energy (kWh), Cost or CO₂.
  • Grouping: stack the bars by Solar vs grid, by charge point or by vehicle, with a colour legend.
  • Rich tooltips: hover or tap a bar to see every series and the total for that day, month or year.
  • Everything is computed in the browser from a single cached request, so navigating periods and toggles is instant.
  • On older ha-evcc versions the card automatically falls back to the previous entity/recorder based statistics.

• Filter repeating plans by vehicle. A new repeating_plan_vehicles option lets you limit the repeating-plans view to specific vehicles.

• Heating loadpoints are handled correctly. Loadpoints that evcc marks as heating (for example a heat pump) are no longer shown with an electric-vehicle charge plan. Their target and limit are now labelled and shown as a temperature (°C) instead of a state of charge.

Good to know

• The new forecast, sessions and plan-preview features need the ha-evcc integration 2026.6.x or newer by @marq24 (the version that ships the WebSocket data API). Without it, the card keeps working and falls back to the existing entity-based behaviour. The card detects this automatically.
• The card stays easy on resources: data is fetched over the already authorized Home Assistant WebSocket connection, cached on both the integration and the card side, and reused across renders. An idle statistics card causes practically no extra load on evcc.
