<details> <summary><b>The Automation Process:</b> 👈</summary>

  • Auto Trigger:

    • When the derivative percentage rises above a set value, the fan turns ON
    • When the derivative percentage falls below a set value, the automation waits for a time delay and then turns the fan OFF.
    • Optional - Set a maximum humidity percentage to trigger the fan ON. This is useful when having back-to-back showers.

    Note: You must have a humidity sensor in the bathroom and set up a 'Derivative Helper' for this automation to work.

  • Manual Trigger Option:

    • This feature allows you to manually trigger the automation.
  • Multi-Speed Fan Control Option:

    • You have the option to use fan speeds to control the staging of your fan.
    • You can choose to stage your fan in your preferred configuration, such as High/Off, High/Low, High/Low/Off, High/Med/Low, etc.
  • Winter Mode Option:

    • You have the option to use 'Winter Mode.' This mode allows for different settings to be applied, accommodating the typically higher humidity levels experienced in winter compared to summer.
  • Light Control Option:

    • Use the "Light Control" option to turn ON lights, adjusting brightness levels, colour temperatures, and transition times.
    • This feature is commonly utilized with LED lights in a shower niche.
    • For expanded lighting options, consider integrating my 💡Sensor Light blueprint, which utilizes the automation link feature.
  • Manual Control Option:

    • Use a manual fan switch to toggle the fan ON/OFF.
    • Opt to use the auto-OFF option for timer-like functionality.
    • This is particularly useful for removing unwanted fumes from deodorant, hairspray, or the toilet.
  • Automation Link Option:

    • This feature simplifies the process of automatically disabling your other automations by providing an automation linking mechanism.
  • Bypass Functionality Option:

    • This allows you to bypass the automation, offering manual control and additional customization capabilities.
  • Safety Measures:

    • Set a maximum runtime safeguard for the fan to prevent continuous operation.
    • Benefit from built-in safeguards to ensure smooth operation and reliability, even if Home Assistant restarts.
  • Blueprint Add-On Integration:

    • Sensor Light: Control your lights in the bathroom. Click Here to learn more.
    • Toilet Exhaust Fan: Integrate with a toilet in the bathroom. Click Here to learn more.
