Wattr
Smart & Sustainable Swimming
Free
The wattr pool control system makes use of an advanced swimming pool model to efficiently manage your pool's heat pump. Our self-learning algorithm integrates this model, your preferences, and weather forecasts to predict and optimize energy consumption. The system comes with a physical controller, connecting all your pool devices, and an easy-to-use mobile app, putting you in complete control. Please note: This app requires a Wattr module to function. The Wattr module is a separate device that connects to your pool installation and tracks its energy consumption. Without the Wattr module, the app will not be able to provide any data or functionality.
