Adaptive Cover

This Custom-Integration provides sensors for vertical and horizontal blinds based on the sun's position by calculating the position to filter out direct sunlight.

This integration builds upon the template sensor from this forum post Automatic Blinds

Installation

HACS (Recommended)

Add https://github.com/basbruss/adaptive-cover as custom repository to HACS. Search and download Adaptive Cover within HACS.

Restart Home-Assistant and add the integration.

Manual

Download the adaptive_cover folder from this github. Add the folder to config/custom_components/.

Restart Home-Assistant and add the integration.

Setup

Adaptive Cover supports (for now) three types of covers/blinds; Vertical and Horizontal and Venetian (Tilted) blinds. Each type has its own specific parameters to setup a sensor. To setup the sensor you first need to find out the azimuth of the window(s). This can be done by finding your location on Open Street Map Compass.

Modes

This component supports two strategy modes: A basic mode and a climate comfort/energy saving mode that works with presence and temperature detection.

Basic mode

This mode uses the calculated position when the sun is within the specified azimuth range of the window. Else it defaults to the default value or after sunset value depending on the time of day.

Climate mode

This mode calculates the position based on extra parameters for presence, indoor temperature, minimal comfort temperature, maximum comfort temperature and weather (optional). This mode is split up in two types of strategies; Presence and No Presence.

Climate strategies

• No Presence: Providing daylight to the room is no objective if there is no presence.

  • Below minimal comfort temperature: If the sun is above the horizon and the indoor temperature is below the minimal comfort temperature it opens the blind fully or tilt the slats to be parallel with the sun rays to allow for maximum solar radiation to heat up the room.

  • Above maximum comfort temperature: The objective is to not heat up the room any further by blocking out all possible radiation. All blinds close fully to block out light.
    
    If the indoor temperature is between both thresholds the position defaults to the set default value based on the time of day.

• Presence (or no Presence Entity set): The objective is to reduce glare while providing daylight to the room. All calculation is done by the basic model for Horizontal and Vertical blinds.
  
  If you added a weather entity, it will only use the above calculations if the weather state corresponds with the existence of direct sun rays. These states are sunny,windy, partlycloudy, and cloudy by default, but you can change the list of states in the weather options. If not equal to these states the position will default to the default value to allow more sunlight entering the room with minimizing the glare due to the weather condition.
  
  Tilted blinds will only deviate from the above approach if the inside temperature is above the maximum comfort temperature. In that case, the slats will be positioned at 45 degrees as this is found optimal.

Entities

The integration dynamically adds multiple entities based on the used features.

These entities are always available:

Entities	Default	Description
sensor.{type}_cover_position_{name}		Reflects the current state determined by predefined settings and factors such as sun position, weather, and temperature
sensor.{type}_control_method_{name}	intermediate	Indicates the active control strategy based on weather conditions. Options include winter, summer, and intermediate
sensor.{type}_start_sun_{name}		Shows the starting time when the sun enters the window's view, with an interval of every 5 minutes.
sensor.{type}_end_sun_{name}		Indicates the ending time when the sun exits the window's view, with an interval of every 5 minutes.
binary_sensor.{type}_manual_override_{name}	off	Indicates if manual override is engaged for any blinds.
binary_sensor.{type}_sun_infront_{name}	off	Indicates whether the sun is in front of the window within the designated field of view.
switch.{type}_toggle_control_{name}	on	Activates the adaptive control feature. When enabled, blinds adjust based on calculated position, unless manually overridden.
switch.{type}_manual_override_{name}	on	Enables detection of manual overrides. A cover is marked if its position differs from the calculated one, resetting to adaptive control after a set duration.
button.{type}_reset_manual_override_{name}	on	Resets manual override tags for all covers; if switch.{type}_toggle_control_{name} is on, it also restores blinds to their correct positions.

When climate mode is setup you will also get these entities:

Entities	Default	Description
switch.{type}_climate_mode_{name}	on	Enables climate mode strategy; otherwise, defaults to the standard strategy.
switch.{type}_outside_temperature_{name}	on	Switches between inside and outside temperatures as the basis for determining the climate control strategy.

Simulation

Blueprint (deprecated since v1.0.0)

This integration provides the option to download a blueprint to control the covers automatically by the provide sensor. By selecting the option the blueprints will be added to your local blueprints folder.
