Towel Heater

Core Functionality

This configuration creates a comprehensive control system for a towel heater with multiple scheduling options and safety features.

Control Methods

1. Manual Control

   • Direct on/off toggle switch
   • Safety timer that automatically turns off the heater after 4 hours

2. Scheduled Operation

   • One-time schedule: Run the heater once at a specific time
   • Workday schedule: Automatically run the heater on workdays at a set time

Configuration Components

• Timer: A 4-hour safety timer that turns off the heater automatically
• Input Fields:
  • Time selectors for one-time and workday schedules
  • Adjustable run time setting (3-5 hours)
  • Toggle switches for manual control and schedule activation

Smart Features

• Calculated Start Times: The system automatically calculates when to start the heater (1 hour before the set time)
• Status Indicators:
  • Current heater status
  • Time until next scheduled use
  • Calculated start and stop times

Safety and Recovery Features

• Automatic shutoff when the timer expires
• Timer restart when Home Assistant restarts if the heater is already on (to make sure the timer ends and thereby shuts of the heater)
• Automatic disabling of one-time schedule after completion

Automations

The system includes multiple automations to handle:

• Turning the heater on/off based on manual control
• Starting/stopping based on schedules
• Synchronizing UI state with actual heater state
• Safety timer management
• Recovery after system restart

You physical device that controls power to the towel heater needs to be added to the code. Replace "switch.towel_heater" in the code with our switch. My configuration uses my switch.towel_heater as a manual control and as a visual cue if the heater is on or of, the automation is set up for the switch to be used that way.
