Requirements

Backend Integration (required)

This card requires one of the following Gardena Smart System integrations:

Integration	Repository	Notes
hass-gardena-smart-system	py-smart-gardena/hass-gardena-smart-system	Requires v2.0+ (tested up to 3.0.2). Provides full device control via custom services.
ha-gardena-smart-system	kayloehmann/ha-gardena-smart-system	Requires v2.x (gardena_smart_system_ng); its local gateway access mode (v2.1.0+) works transparently. Card versions up to v0.7.1 supported v1.x instead. Uses standard HA service calls.

The card auto-detects which backend is installed and adapts accordingly.

Schedule Integration (optional)

The card supports two schedule sources. You can use either or both:

Source	Integration	How it works
Gardena App	Gardena Smart Schedule	Reads schedules configured in the Gardena Smart App and exposes them as sensor entities.
Scheduler	scheduler-component + scheduler-card	Create and manage schedules locally in Home Assistant with a visual editor.

The card auto-detects both sources. Gardena App schedules are shown with a calendar icon, scheduler-component schedules with a clock icon. When both sources exist for a device, each section is labeled ("Gardena" / "Scheduler").

Display mode (config option show_scheduler_schedules):

• mixed (default) — all schedules in one list
• separate — scheduler schedules in their own labeled section

Without any schedule integration the card works fully, but no schedule rows are shown. See Schedule Documentation for details, recommended scheduler-card configuration, and alternatives using Home Assistant automations.
