The GROHE Sense Guard water control system continuously monitors water pressure in the pipes, detecting every anomaly from minor leaks to a major burst. Once a pipe burst is detected, the water supply is automatically shut off and an alert is sent to your smartphone. Aqua self-learning algorithm learns your patterns of water consumption and alerts you if your water consumption is higher than usual, even detecting minor leaks and notifying you on your smartphone. GROHE Sense Guard also monitors changes in temperature and water pressure to help prevent frost damage. Grohe Sense Guard connects to your home Wi-Fi network. In the case of a connectivity loss, GROHE Sense Guard continues to protect your home by shutting off water in the event a pipe burst occurs.
