Home Assistant Timer with Input Datetime Blueprint

This Home Assistant blueprint enables the creation of a timer that can be set and adjusted through the Home Assistant user interface using an input_datetime entity. This method provides a flexible way to manage time-based automations directly from the dashboard.

Features

• User-Friendly Interface: Easily set timers using a time input in the UI.
• Precision Timing: Specify exact hours and minutes for your timers.
• Reusable: Use this blueprint to add timer functionality to any automation requiring precise time control.

Prerequisites

Before using this blueprint, you should have:

• Home Assistant installed.
• Basic understanding of Home Assistant configuration and automation.

Installation

1. Add the Blueprint:

   • Navigate to the Home Assistant UI, go to Configuration > Blueprints.
   • Click on the import blueprint button and use this URL to import: https://github.com/tdobrovolny/ha-timer-with-input-datetime/blueprints/automation/timer_with_input_datetime.yaml

2. Create the Required Entities: Add the following to your configuration.yaml file:

   input_datetime:
     timer_duration:
       name: Timer Duration
       has_date: false
       has_time: true
   
   timer:
     my_timer:
       duration: '00:00:00'

Using the Blueprint

1. Create a New Automation from the Blueprint:

    - Go to Configuration > Automations.
    - Click the “+ ADD AUTOMATION” button.
    - Select “Use Blueprint”.
    - Choose “Timer with Input Datetime” from the list.
   

   2. Configure the Automation: For Input Datetime Entity, select the input_datetime entity you created (e.g., input_datetime.timer_duration). For Timer Entity, select the timer entity you created (e.g., timer.my_timer).

   3. Save and Test:

      • Save the automation.
      • Set the desired timer duration using the input datetime helper on your dashboard.
      • The timer should start with the set duration.
