v2.9.0 - Template Whisperer

Solar Bar Card - Releases

v2.9.0 — Template Whisperer

New Features

• HA Jinja2 label templates: Any label configurable via custom_labels or label_* YAML keys now accepts full Home Assistant Jinja2 template syntax. When a value contains {{, it is evaluated server-side via the HA websocket render_template API and updated reactively. Static label strings continue to work as before — no migration needed. The Custom Labels section has been removed from the visual editor (labels are YAML-only with template support); all previously configured labels remain fully compatible.

  custom_labels:
    solar: "{{ states('sensor.inverter_model') }}"
    export: "{{ 'Selling' if states('sensor.export_power')|float > 0 else 'Export' }}"

• Bar segment text templates (segment_text_*): Each of the five bar segments now accepts a freeform text template with token substitution. Configure via YAML; leave unset to use the default value label format. Available tokens:

  Token	Description
  {value}	Formatted power value (respectspower_unit and show_power_unit)
  {label}	Translated or custom label for this segment
  {percent}	Segment width as a rounded percentage of the bar
  {raw}	Raw numeric value (integer W or decimal kW, no unit suffix)

  Config keys and their segments:

  Key	Segment
  segment_text_solar_home	Solar → Home (self-consumption)
  segment_text_solar_ev	Solar → EV
  segment_text_battery_charge	Solar → Battery
  segment_text_export	Export
  segment_text_ev_potential	EV potential (pre-charge overlay)

  segment_text_solar_home: "{value}"
  segment_text_export: "{percent} → grid"
  segment_text_battery_charge: "⚡ {raw}W"
