Operating Instructions
App Control
After successful pairing, you can control the connected appliance remotely via the eWeLink app. The app allows you to turn the switch on/off, view real-time energy data, set schedules, and configure various smart scenes.
Voice Control
The SONOFF POWR320D Elite is compatible with Amazon Alexa and Google Home. Link your eWeLink account to your voice assistant app to enable voice commands for controlling your devices.

Scheduling and Timers
Set one-time, repeating, or countdown timers to automatically turn appliances on or off. This feature is useful for automating daily routines and saving energy.

Inching Mode
Inching mode allows the device to automatically turn off after a set duration (e.g., 0.5 seconds to 3600 seconds) once it's turned on. This is useful for devices that only need to be on for a short period.

Energy Monitoring and Management
The POWR320D Elite provides comprehensive energy monitoring capabilities to help you understand and manage your power consumption.
Real-time Data and Historical Records
View real-time current, voltage, and power readings on the device's LCD screen or in the eWeLink app. The app also stores up to 6 months of historical consumption data, accurate to the hour, which can be exported for detailed analysis.

Consumption Goal and Notifications
Set daily or monthly power consumption thresholds. The device can send push notifications to your phone when the consumption exceeds a customized value, helping you stay within your energy goals.

Overload Protection
Configure maximum power, current, and voltage thresholds. If the connected appliance's usage exceeds these limits, the POWR320D Elite will automatically shut off to prevent damage to the appliance and ensure safety.
Figure 9: An illustration of the overload protection feature, demonstrating how the device safeguards appliances by automatically turning off when set thresholds are exceeded.
Smart Scenes for Energy Saving
Create smart scenes in the eWeLink app to automate energy-saving actions. For instance, if today's energy consumption exceeds a certain kWh, you can set a scene to automatically turn off specific high-power appliances like water heaters or air conditioners.
