Risinglink

Risinglink WiFi Power Outage Alarm Detector, Power Failure & Restoration Alerts with SMS Text, Email & Audible Alarm

Main Highlights

ENGINEERED IN THE USA EASY SETUP : Engineered in the USA for reliability and supported by a dedicated US-based team. No hubs, apps, subscriptions, or monthly fees required. Risinglink delivers direct SMS text, email, and audible alerts without relying on third-party smart-home platforms. Works with 2.4GHz WiFi networks (not compatible with 5GHz-only networks).
INSTANT POWER OUTAGE ALERTS: Detects power failures in as little as 3 seconds and immediately sends alerts. Even brief power interruptions are detected, helping you identify abnormal power conditions and take preventive action before they happen again. You will also receive an alert when power is restored.
TRUE SMS TEXT MESSAGE ALERTS: Receive direct SMS text alerts, not just app push notifications that can be missed if apps are logged out or notifications are disabled. Supports up to 2 phone numbers and 4 email addresses, so multiple people can receive outage alerts at the same time.
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.
LOCAL AUDIBLE ALARM + LONG BACKUP BATTERY: An integrated 85 dB audible alarm sounds immediately during power outages, even without Wi-Fi, providing an additional layer of protection. The alarm can be disabled during setup if preferred. The pre-installed backup battery is designed to last over 5 years under typical usage, ensuring reliable monitoring.
COMPREHENSIVE NOTIFICATIONS: Receive alerts not only for power outages and restorations, but also for 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.
2.4GHz WIFI COMPATIBILITY: Supports 2.4GHz WiFi only. Most WiFi routers support 2.4GHz networks. To send alerts promptly after a power loss, the device requires a few seconds of active Wi-Fi and internet connection.
