GoKawiilShelly launches sub-$30 Matter leak sensor with Apple Home support
Shelly has released the Flood S Gen4, a Matter-certified water leak sensor priced under $30 that works natively with Apple Home, Google Home, Alexa, SmartThings, and Home Assistant. The device uses three large stainless steel contact pads instead of small metal pins, allowing it to detect water faster and even sense low-conductivity liquids like AC condensate.
