Shade Complete (ha-shade-complete)

The definitive, full-featured Home Assistant integration for motorized shades, blinds, and rollers.

🌟 Why Shade Complete?

Most smart motorized shades (whether Z-Wave, Zigbee, Matter, Somfy, Tuya, or ESPHome) come with frustrating limitations out of the box:

• Missing Tilt Controls: Blinds with motorized tilt often only expose open_tilt or raw tilt position attributes that cannot be operated like normal covers from dashboards or voice assistants.
• Dumb Static Schedules: Closing shades at fixed hours fails as the sun's trajectory shifts across seasons.
• Inaccurate or Broken Battery Reporting: Lithium batteries discharge along a curve that confuses uncalibrated firmware—often dropping to 50% in two weeks, staying there for months, or abruptly dying at 30%. In addition, voltage sag during active motor movement triggers false "low battery" alarms.
• Orphaned Entities: Helper entities often clutter Home Assistant as separate virtual devices rather than living on the physical shade's device card.

Shade Complete solves all of this in one elegant, cohesive integration.

✨ Features

☀️ 1. Intelligent Solar Vector Tracking (Shade & Group Level)

• Window Orientation & Field of View: Configure your window's facing direction (N, NE, E, SE, S, SW, W, NW or custom degrees 0–360°) with customizable azimuth tolerance (half-angle FOV) and clean $360^\circ$ North wraparound.
• Solar Elevation Mapping: Seamlessly interpolates between your low elevation cutoff (e.g. $5^\circ$) and high elevation threshold (e.g. $40^\circ$) to dynamically keep direct glare out while preserving ambient daylight.
• Overcast & Storm Suppression: Monitors an optional weather.* entity to suppress tracking on cloudy, foggy, or rainy days, automatically opening shades to maximize natural light.
• Arbitrated Manual Overrides: If a user physically adjusts a shade or any member shade in a group via a wall remote or dashboard, Shade Complete yields immediately, detects the override, and automatically resumes tracking after a configurable timeout (or at sunset).
• Travel Verification: Automatically monitors movement duration; if motion is halted or intercepted before arrival, manual override is flagged instantly.
• Group Solar Tracking: Synchronized groups can follow the same sun-tracking geometry, coordinating multiple physical shades smoothly.

🔄 2. Virtual Tilt Projection & Low-Percentage Interception

• Automatic Cover Entity Creation: When configuring a smart shade whose underlying physical device supports tilt (or when tilt interception is enabled), Shade Complete automatically provisions both the main SmartTrackingShadeCover and a co-located TiltCoverEntity directly on the physical device's card.
• Seamless Low-Percentage Tilt Interception: Ever wanted to slightly tilt your blinds open using a single slider without lifting the shade roller? Enable Low-Percentage Tilt Interception (threshold 1–5%, configurable up to 15%). Commands in the 1–5% range are automatically converted into 0–100% slat tilt adjustments (set_cover_tilt_position), while commands above the threshold adjust the shade height normally.
• Native Device Card Binding: Inspects the Home Assistant Device Registry and binds helper entities directly to the physical shade's device card (DeviceInfo). Your tilt controls, sun tracking entities, and battery sensors live right beside the physical hardware!

⏰ 3. Automated Morning Open & Evening Close Schedules

• Configurable per Shade or Group: Set automated daily routines for opening and closing.
• Flexible Trigger Modes:
  • Clock Time: e.g., Open at 07:30:00 to 100% (or custom target position), close at 21:30:00.
  • Solar Event (Sunrise / Sunset): Open with a configurable offset from sunrise; close with an offset from sunset.
• Re-Arming Daily Locks: Prevents redundant triggers throughout the day while automatically resetting manual overrides overnight.

🔋 4. Adaptive Battery Intelligence & Calibration

• Motor-Sag Rejection: Voltage temporarily plunges when a motorized shade draws inrush current. Shade Complete inhibits calibration sampling during active motor motion, eliminating false low-battery alerts.
• Exponential Moving Average (EMA): Smooths sensor noise without lag.
• Online Bounds Learning: Observes your battery's actual low-voltage cutoff point and full-charge peak over time, dynamically calibrating the true 0–100% scale for your specific hardware.
• Charging Detection: Automatically detects when the shade is plugged into a solar or USB charger and isolates charging peaks from discharge curves.
• Low Battery Diagnostics & Alert Blueprint: Ships with a ready-to-use Home Assistant automation blueprint (blueprints/automation/spelech/shade_low_battery_notification.yaml) alerting you when any shade falls below its critical battery threshold.

👥 5. Synchronized Shade Groups

• Group multiple individual shades or tilt entities into a single unified cover.
• Concurrent command execution via asyncio.gather for synchronized group movement and tilt positioning.
• Computes true average position across all member shades.
• Supports group-level solar tracking, scheduled open/close routines, and member override detection.
