Redsea ReefControl Lite controller
The ReefControl Lite is a smart, modular aquarium controller designed to give reef keepers reliable, real-time monitoring and automation for their systems. At its core this controller is the central hub of Red Sea’s ReefBeat ecosystem, connecting to digital ReefSense probes to track your tank’s vital parameters 24 hours a day.
Out of the box it includes a combined pH and temperature ReefSense probe that is automatically temperature compensated and delivers high-accuracy data right to your phone via the ReefBeat app.
ReefControl Lite lets you automate key functions of your reef environment. Using the ReefBeat app you can set threshold triggers that automatically control a 12 V DC device like an ATO pump or cooling fan. If integrated with a ReefControl Power unit, the system can also take sensor readings to manage AC devices such as heaters, chillers etc, turning them on or off based on real readings rather than guesswork. The ReefBeat app also records historical data, sends notifications if parameters stray outside your desired ranges, and guides you through probe calibration with all calibration data stored on the probes themselves.
The Lite controller supports up to two ReefSense probes or sensors and one controllable 12 V output ideal for small to medium marine systems where core stability of pH and temperature is critical. Its digital sensors reduce interference compared to traditional analog probes and allow Bluetooth-enabled remote probe usage for tasks such as checking newly mixed saltwater at your mixing station. With firmware updating over Wi-Fi and the ability to integrate future ReefSense probe types, ReefControl Lite is built to grow with your tank.
