Risinglink
Risinglink Power Failure Alarm, Power Failure Detector, with Text Message, Email, and Audio Alerts(2nd Generation)
View Deal on:
View Deal
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.)
- Prompt Detection: Our device identifies power outage within 3 seconds and alerts you instantly. Experience faster responsiveness than many competitors that require much longer to recognize a power outage. Be in the know of even short power interruptions, enabling you to act preventively.
- Enhanced Alert Reliability: Risinglink allows you to register 2 phone numbers and 4 email addresses per device. Be cautious of competitors claiming to support multiple phones; they actually restrict you to just a single phone number for the direct text alert and rely on potentially unreliable Email-to-SMS services for the 2nd phone. If you and an additional contact, such as your spouse or coworker, both need to receive timely and reliable text alerts, Risinglink is the right choice for you!
- 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.
- Durable Backup Battery: Our device is built with an internal backup battery designed to last over 5 years, considering average power outages and maintaining a stable wifi connection. When not relying on the backup, the device seamlessly draws power from the A/C outlet it monitors.
- Optimal Performance Note: Our device is engineered to promptly keep you informed. To achieve this, it requires just a few seconds of active Wi-Fi and internet connection after a power loss to dispatch alerts.
