All Off When Away

S.C.O.R.E. → Convenience → Device Control

Overview

Leaving home often leads to unnecessary energy consumption from devices that remain powered on. This capability automatically turns off nonessential devices when everyone leaves, enhancing energy efficiency and providing peace of mind.

Benefits

• Reduces energy costs by minimizing power usage when the home is unoccupied.
• Increases safety by ensuring devices like irons or heaters are turned off.
• Provides convenience by eliminating the need to manually check and power down devices before leaving.

Intent

The purpose of this capability is to streamline energy management by automatically powering down nonessential devices when the last person leaves the home. This results in lower energy bills and a more secure home environment.

Preconditions

• Home Assistant must be installed and set up.
• Presence detection must be configured to recognize when all individuals have left the home.
• Nonessential devices should be integrated with Home Assistant for control.
• Home Assistant installed and configured.
• Integration available and authenticated: Zigbee2MQTT.

3. Send Turn Off Command

Home Assistant sends commands to the identified nonessential devices to turn them off.

4. Confirmation of Actions

The system confirms that all commands were successful and devices are powered down.

5. Log Activity

Home Assistant logs the actions taken for future reference and monitoring.

Postconditions

All nonessential devices are powered down, leading to reduced energy consumption and an empty, secure home.

Optional Enhancements

• Integrate with smart thermostats to adjust temperature settings when away.
• Add notifications to inform the homeowner when devices have been turned off.
• Enable a schedule for specific devices to turn off at certain times, even when someone is home.
