Outdoor-Ready The main controller is designed for outdoor use with an IP65 waterproof rating, ensuring durability and protection from the elements.
Multiple Notifications Receive alerts via email and text message for high or low water levels, water level returning to normal, low battery, and device offline (WiFi connection lost). Unlike typical systems that only alert during abnormal conditions, ours also notifies you when the water level returns to normal providing a complete picture and added peace of mind.
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; some restrict direct text alerts to only one phone number, relying on unreliable Email-to-SMS services for the 2nd phone. Others depend entirely on Email-to-SMS for all alerts. If you and an additional contact, such as a spouse or coworker, need timely and reliable text alerts, Risinglink is the right choice for you!
Intelligent Alert System Proprietary algorithm prevents repetitive alerts triggered by water bouncing. After water level alert triggered, the device checks water levels every 5 minutes until normalization, and then sends an alert cancellation notification.
Long-Lasting Power Powered by 3 included AAA batteries, eliminating the need for a power outlet. With smart power management, these new batteries can last for years under normal usage and a good Wi-Fi signal.
