Bathroom Lights App

Overview

The Bathroom Lights app (BathRoomLights.cs) provides comprehensive bathroom automation including motion-activated lighting, shower mode with music integration, smart toothbrush automation, and Hue switch control. It creates an intelligent bathroom environment that adapts to different activities and times of day.

Key Features

🚶‍♂️ Motion-Based Lighting

  • Dual Light Control: Controls both ceiling light (plafond_badkamer) and mirror light (badkamer_spiegel)
  • Adaptive Brightness: 5% brightness when sleeping, 100% when awake
  • Smooth Transitions: 2-second transition times for comfortable lighting changes
  • Sleep State Awareness: Automatically detects sleep state for appropriate brightness
  • Configurable Timeouts: Separate day and night timeout periods via input numbers

🚿 Comprehensive Shower Mode

  • Music Integration: Automatically starts Spotify via Google Home
  • Volume Control: Sets audio volume to 40% for shower ambiance
  • Environmental Control: Closes roller blinds for privacy
  • Extended Lighting: 1-hour timeout with warning notifications
  • Discord Notifications: Alerts when shower mode times out
  • Full Brightness: Ensures optimal lighting during shower activities

🎵 Smart Toothbrush Automation

  • Automatic Music Start: Detects toothbrush activation and starts music at 15% volume
  • Timer Integration: Monitors brushing duration and patterns
  • Auto-Stop: Stops music after 30 seconds of toothbrush idle time
  • Health Routine Support: Encourages proper oral hygiene timing

🔘 Advanced Hue Switch Control

  • 4-Button Control: Complete Hue switch integration with multiple functions
  • Button 1: Toggle shower mode on/off
  • Button 2: Direct light control toggle
  • Button 3: [Custom function]
  • Button 4: [Custom function]
  • Physical Override: Always provides manual control regardless of automation state

🌙 Sleep & Time Awareness

  • Night Mode Detection: Uses house mode and sleep state for intelligent behavior
  • Configurable Timers: Separate timeout settings for day (input_number.bathroom_light_daytime) and night (input_number.bathroom_light_nighttime)
  • Sleep State Integration: Coordinates with Sleep Manager for optimal brightness
  • House Mode Coordination: Integrates with central house state management

Technical Implementation

Motion Detection Logic

private void InitializeLights()
{
    Entities.BinarySensor.BadkamerMotion
        .StateChanges()
        .Where(x => x.New.IsOn())
        .Subscribe(_ => TurnOnLights());

    // Auto turn off after 2 minutes (normal) or 60 minutes (shower mode)
    Entities.BinarySensor.BadkamerMotion
        .StateChanges()
        .Where(x => x.New.IsOff())
        .Subscribe(_ => ScheduleTurnOff());
}

Shower Mode Detection

private bool IsDouching => Entities.InputBoolean.Douchen.IsOn();

private void ScheduleTurnOff()
{
    var delay = IsDouching ? TimeSpan.FromHours(1) : TimeSpan.FromMinutes(2);
    
    Scheduler.Schedule(delay, () =>
    {
        if (!DisableLightAutomations && Entities.BinarySensor.BadkamerMotion.IsOff())
        {
            Entities.Light.Badkamer.TurnOff();
        }
    });
}

Night Mode Lighting

private bool IsNighttime => Entities.InputSelect.Housemodeselect.State == "Night";

private void TurnOnLights()
{
    if (DisableLightAutomations) return;
    
    if (IsNighttime)
    {
        // Dim lighting for nighttime
        Entities.Light.Badkamer.TurnOn(brightnessPct: 30);
    }
    else
    {
        // Full brightness for daytime
        Entities.Light.Badkamer.TurnOn(brightnessPct: 100);
    }
}

Configuration

Required Entities

  • Motion Sensor: binary_sensor.badkamer_motion
  • Bathroom Light: light.badkamer
  • Shower Mode: input_boolean.douchen
  • Disable Automation: input_boolean.disablelightautomationbathroom
  • House Mode: input_select.housemodeselect
  • Toothbrush Sensor: sensor.toothbrush_active (or similar)

Timing Configuration

  • Normal Timeout: 2 minutes after motion stops
  • Shower Timeout: 60 minutes when shower mode is active
  • Night Brightness: 30% of maximum brightness
  • Day Brightness: 100% of maximum brightness

Behavior Scenarios

Scenario 1: Normal Bathroom Use

  1. Motion Detected → Lights turn on at full brightness (or 30% if nighttime)
  2. Motion Stops → 2-minute countdown begins
  3. No Motion for 2 Minutes → Lights turn off automatically
  4. Motion During Countdown → Countdown resets

Scenario 2: Shower Mode

  1. Shower Mode Activated → input_boolean.douchen turns on
  2. Motion Detected → Lights turn on at appropriate brightness
  3. Motion Stops → 60-minute countdown begins (instead of 2 minutes)
  4. No Motion for 60 Minutes → Lights turn off automatically

Scenario 3: Manual Override

  1. Hue Button Pressed → Toggles shower mode on/off
  2. Disable Automation → All automatic behaviors disabled
  3. Manual Light Control → Direct light control bypasses automation

Scenario 4: Toothbrush Routine

  1. Toothbrush Activated → Music starts playing automatically
  2. Oral Hygiene Routine → Music continues during brushing
  3. Toothbrush Deactivated → Music stops when routine complete

Smart Features

Adaptive Behavior

  • Context Awareness: Different behavior based on house mode (day/night)
  • Usage Patterns: Extended lighting during shower activities
  • Energy Efficiency: Automatic shutoff prevents lights staying on indefinitely

Integration Points

  • House State Manager: Coordinates with overall house state system
  • Away Manager: Respects away mode settings
  • Sleep Manager: Adjusts behavior during sleep hours

Safety Features

  • Motion Safety: Lights won't turn off if motion is still detected
  • Manual Override: Physical controls always work regardless of automation state
  • Disable Switch: Easy way to disable automation when needed
