Energy Monitoring for Smarter Energy Management: Track real-time power usage through the YoLink app to identify and manage energy-intensive devices. Easily export energy usage and power data to analyze trends over time, helping optimize the use of appliances, reduce wastage, and lower bills for home or office settings.
Device-to-Device Control for Enhanced Interaction: The YoLink Relay can function as both a controller or responder, allowing it to directly control or be controlled by other YoLink devices, such as door sensors or motion detectors. This feature enables seamless device interaction without needing an internet connection, ensuring reliable responses and functionality even offline.
Instantaneous Power Status Updates: Refresh and view the current power status directly from the YoLink app, giving you immediate insights into the operational status of connected devices. This feature is invaluable for troubleshooting and ensuring devices are functioning optimally.

Customizable Real-Time Power Alerts for Enhanced Safety: Set high and low real-time power (wattage) alerts via the app to get notified when immediate power draw deviates from your set thresholds. This feature helps you manage device performance effectively and adds an extra layer of safety, alerting you to unexpected power spikes that may indicate potential issues.
Compatible with Third-Party Platforms: Integrate with Alexa, Google Assistant, IFTTT, and Home Assistant for hands-free control and compatibility with a range of third-party platforms, making the relay switch a versatile addition to your smart home.
YoLink Hub Required for Full Functionality: A YoLink Hub is essential to unlock all supported features in the YoLink app, including remote control, scheduling, automation, real-time power monitoring, and customized alerts.
