Risinglink Power Failure Alarm, Power Failure Detector, with Email, Text Message, and Audio Alerts(2nd Generation)

Main Highlights

Easy Setup: Say goodbye to cumbersome hubs and apps. Simply connect the device to your Wi-Fi and enjoy uninterrupted monitoring without any monthly fees or subscriptions. (Note: Only 2.4GHz WiFi supported. However, most WiFi routers nowadays could support both 2.4 and 5 GHz.)

Optimized Text Alerts: We believe in timely alerts. Unlike competitors who impose intervals or monthly caps on direct text alerts, Risinglink ensures you receive every text alert promptly. If your outlet experiences multiple trips in a short period, other systems might only send the initial text alerts, potentially delaying or missing the most critical last power outage alert. With Risinglink, there are no such hidden limitations, ensuring you stay fully informed.

Comprehensive Notifications: Not just power outages! Receive alerts for power restoration, low battery, and device offline (Wi-Fi loss). Unlike some brands that only inform about power status, our device ensures you're never in the dark about battery health or device connectivity..Audible Security: An 85dB alarm sounds during power failures, independent of Wi-Fi. If you prefer a quieter environment, this feature can be disabled during setup..

International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.
