## Sensor Filtering
To improve the stability and reliability of sensor readings, the integration now supports **sensor filtering** for key environmental data collected from the Dantherm unit. This filtering mechanism is applied to the following sensors:
- **Humidity**
- **Air Quality**
- **Exhaust Temperature**
- **Extract Temperature**
- **Supply Temperature**
- **Outdoor Temperature**
- **Room Temperature**
### Control via Home Assistant Switch
The filtering feature can be enabled or disabled via the **"Sensor Filtering"** switch entity. By default, the filtering is **disabled**, ensuring the system behaves as it did previously. When the switch is enabled, the filtering logic described below will be applied.
### How It Works
Each sensor is equipped with a sliding history buffer, storing the last 5 readings. The filter applies two techniques:
1. **Initialization Smoothing**
For the first few readings (up to 5), the filter calculates a simple average. This helps the sensor start off with a stable baseline, preventing a single bad initial reading from influencing the system.
2. **Spike Filtering**
After initialization, every new reading is compared to a rolling average of the last 5 readings.
If the new reading changes more than a defined threshold (`max_change`) compared to the rolling average, the spike is rejected, and the system uses the current rolling average instead.
### Individual Thresholds per Sensor
Each sensor type has a predefined maximum allowed change per reading:
| Sensor | Max Change |
|-------------|------------|
| Humidity | 5% RH |
| Air Quality | 50 PPM |
| Temperatures| 2°C |
This ensures the filtering logic fits the natural dynamics of each sensor type.
> This feature was inspired by [issue #68](https://github.com/Tvalley71/dantherm/issues/68), reported by a community user.
## Actions
### Using the "Dantherm: Set State" and "Dantherm: Set configuration" Actions
The **Dantherm: Set state** action allows you to control the state of your Dantherm ventilation unit directly from a Home Assistant automation. This action provides a wide range of options to customize the operation of your unit, making it suitable for various scenarios.
#### Steps to Use the "Set State" Action
1. **Create a New Automation:**
- Navigate to `Settings` > `Automations & Scenes`.
- Click on **Add Automation** and select **Start with an empty automation**.
2. **Configure a Trigger:**
- Add a trigger that fits your use case. For example:
- A time-based trigger to schedule changes.
- A sensor-based trigger to react to environmental changes.
- Air Quality Sensor: Trigger when CO2 levels exceed a threshold, e.g., 1000 ppm.
- Humidity Sensor: Trigger when humidity exceeds, e.g., 70%.
- Window Sensor: Trigger when a window opens.
- Cooker Hood: Trigger when the smart plug detects power usage above a threshold.
3. **Add the "Dantherm: Set State" Action:**
- Under the **Actions** section, click **Add Action**.
- Search for `Dantherm: Set state` in the action picker and select it.
4. **Configure the Action:**
- Use the options provided to control the Dantherm ventilation unit:
- **Targets:** Choose the area, device, or entity to apply the action.
- **Operation Selection:** Set the desired operating mode (e.g., Standby, Automatic, Manual, or Week Program).
- **Fan Selection:** Choose the desired fan level (Level 0–4).
- **Modes:** Toggle special modes like:
- **Away Mode**: Enable or disable away mode.
- **Summer Mode**: Turn summer mode on or off.
- **Fireplace Mode**: Activate fireplace mode for a limited period.
- **Manual Bypass Mode**: Enable or disable manual bypass.

5. **Save the Automation:**
- Once configured, save the automation. The Dantherm unit will now respond to the specified trigger and perform the desired action.
The **Dantherm: Set configuration** action allows you to adjust various configuration settings of your Dantherm device directly from Home Assistant. This action can be used in automations, scripts, or manually through the Developer Tools.

## ⏳ The following sections are a work in progress
These features are planned for version **0.5.0**. The calendar function is currently still under development.
## Integration enhancements
The integration enhances the control of Dantherm ventilation units by introducing **Boost Mode**, **Eco Mode**, **Home Mode**, and a **Calendar Function** for advanced scheduling and automation. These features ensure efficient operation based on both **schedules** and **various triggers**, providing a comfortable and energy-efficient environment.
### Boost Mode 🚀
Boost Mode is designed for short bursts of increased ventilation, useful after activities like cooking or showering.
- **Boost Mode Switch**: This must be **enabled** for Boost Mode to activate.
- **Trigger-Based Activation**: If Boost Mode is **enabled** and the **Boost Mode Trigger** is active, the unit switches to the **Boost Operation Selection**.
- **Timeout Handling**: [See Trigger Timeout](#trigger-timeout) for details on how long Boost Mode remains active after the trigger is deactivated.
- **Available Operations**: `Level 4`, `Level 3`, or `Level 2`.
> **Important**
> The Dantherm unit has a built-in **automatic setback** from `Level 4` to `Level 3` after a fixed time period. This may cause Boost Mode to behave unexpectedly if `Level 4` is used for longer periods.
### Eco Mode 🌱
Eco Mode is designed to **reduce fan speed** under specific environmental conditions, optimizing efficiency and supporting the unit’s **defrost mechanism** in cold weather.
- **Eco Mode Switch**: This must be **enabled** for Eco Mode to activate.
- **Trigger-Based Activation**: If Eco Mode is **enabled** and the **Eco Mode Trigger** is active, the unit switches to the **Eco Operation Selection**.
- **Timeout Handling**: [See Trigger Timeout](#trigger-timeout) for details on how long Eco Mode remains active after the trigger is deactivated.
- **Available Operations**: `Standby` and `Level 1`.
> **Important**
> The Dantherm unit has a built-in **automatic setback** from `Standby` to `Level 3` after a fixed time period. This may cause Eco Mode to behave unexpectedly if `Standby` is used for longer periods.
### Home Mode 🏡
Home Mode allows for automatic adjustments based on a **Home Mode Trigger**, ensuring efficient ventilation when you are at home.
- **Home Mode Switch**: This must be **enabled** for Home Mode to activate.
- **Trigger-Based Activation**: If Home Mode is **enabled** and the **Home Mode Trigger** is active, the unit switches to the **Home Operation Selection**.
- **Timeout Handling**: [See Trigger Timeout](#trigger-timeout) for details on how long Home Mode remains active after the trigger is deactivated.
- **Available Operations**: `Automatic`, `Level 3`, `Level 2`, `Level 1`, or `Week Program`.
Trigger Timeout ⏱️
Each mode trigger (Boost, Eco, Home) includes a configurable timeout that defines how long the mode remains active after the trigger is deactivated.
- **Timeout Behavior**: After the trigger turns off, the unit continues operating in the triggered mode for the remaining timeout period.
- **Reset on Re-trigger**: If the trigger is activated again *within the timeout window*, the countdown restarts.
- **Automatic Revert**: When the timeout expires without further trigger activity, the unit reverts to the operation mode that was active before the trigger event—unless this has been overridden by a calendar schedule.
This mechanism ensures that temporary conditions (e.g., presence, humidity, low temperature) cause a short-term mode change without disrupting long-term schedules.
### Adaptive Triggers ⚡
Boost, Eco, and Home Modes rely on **Adaptive Triggers** — binary sensors or helpers that determine **when a mode should activate**.
An **Adaptive Trigger** can be:
- A **motion sensor** (e.g., presence detection for Home Mode)
- A **humidity sensor** (e.g., high humidity after a shower for Boost Mode)
- A **power sensor** (e.g., detecting stove or shower fan usage)
- An **outdoor temperature sensor** (e.g., reducing fan speed in cold weather for Eco Mode)
- A **custom helper** combining multiple conditions
Adaptive Triggers are configured manually in the integration options and linked to each mode individually.
> ⚠️ **Note**
> Only entities of type `binary_sensor` or `input_boolean` are supported as Adaptive Triggers.
> Make sure the entity returns an `on` or `off` state.
### Trigger Entity Availability 🛑
Entities related to Boost, Eco, and Home Modes (e.g., mode switch, timeout, operation selection) are **disabled by default** unless a corresponding trigger is configured.
If you manually enable these entities via Home Assistant, they will be **automatically disabled again after a reload** of the integration unless a valid trigger is set in the integration options.
### Configuring an Adaptive Trigger
#### Steps to set up an Adaptive Trigger:
1. **Go to Home Assistant → Integrations → Dantherm.**

2. **Click the Configure button** for the desired Dantherm integration instance.

3. **Enter the trigger entity**:
- Use the appropriate field (e.g., `Boost Mode Trigger`, `Eco Mode Trigger`, `Home Mode Trigger`)
- Examples: `binary_sensor.kitchen_motion`, `binary_sensor.living_room_presence`, `binary_sensor.outdoor_temperature_low`
4. **Click Submit** to save the configuration.
5. **Enable the corresponding mode** in the UI.
Once configured, the Dantherm unit will automatically switch to the selected **operation mode** whenever the **Adaptive Trigger** becomes active. ⚡
### Calendar Function 📅
The Calendar Function allows precise scheduling of different operation modes, providing full automation of the ventilation system.
- **Integration - Calendar Events**:
By entering an event word into the **summary** of a calendar event, the selected operation will take effect when the event starts, assuming it has a **higher priority** event words than an ongoing event. When the event ends, the system will revert to the **previously active event**. If no underlying event exists, the unit will revert to the **Default Operation Selection**.
- **Event Words**: You can schedule "**Level 1**", "**Level 2**", "**Level 3**", "**Automatic**", "**Away Mode**", "**Night Mode**", "**Boost Mode**", "**Home Mode**", "**Eco Mode**", and "**Week Program**". These terms will be translated according to the selected language in Home Assistant, assuming your language is supported by the integration.
- If **Level 1** to **Level 3** is scheduled, the unit will run in Manual mode at the selected fan level.
- If **Automatic** is scheduled, the unit will operate in Demand Mode.
- If **Away Mode** is scheduled, Away Mode will be **enabled at the start** and **disabled at the end** of the event.
- If **Night Mode** is scheduled, Night Mode will be **enabled at the start** and **disabled at the end** of the event.
- If **Boost Mode**, **Home Mode**, or **Eco Mode** is scheduled, the respective mode’s trigger will be **enabled at the start** and **disabled at the end**, allowing the unit to switch modes dynamically.
- If **Week Program** is scheduled, the unit will follow the selected program in **Week Program Selection**.
- **Priority System**: The following is the **priority order** for calendar scheduling:
1. **Away Mode** (highest priority)
2. **Boost Mode**
3. **Night Mode**
4. **Home Mode**
5. **Eco Mode**
6. **Level 3**
7. **Level 2**
8. **Level 1**
9. **Automatic**
10. **Week Program** (lowest priority)
The available operations in **Default Operation Selection** are **Automatic**, **Level 3**, **Level 2**, **Level 1**, or **Week Program**.
> [!IMPORTANT]
> The Dantherm unit has built-in **Night Mode Start Time** and **Night Mode End Time**. Scheduling Night Mode outside of these times may not function as expected.
These features provide **seamless automation and intelligent airflow control**, ensuring the ventilation system adapts dynamically to both **planned schedules** and **real-time environmental conditions**. 🚀🏡🌱📅
