Protect Outdoor Furniture with Automated Rain Detection

Perfect for: Patios, decks, and garden seating areas
 
Outdoor lounging spaces can be quickly ruined by unexpected rain. Using Rain Mode, Shelly Flood Gen4 detects the early signs of rainfall by sensing rising humidity levels on its surface – a reliable indicator before water visibly accumulates. When paired with Shelly 2PM Gen4 to control your motorized awning, it can automatically extend the cover to shield your furniture the moment rain begins. 
 
 
💡 Note: Shelly Flood Gen4 can detect rain using its leak sensor cable. The main device is IP44 rated and must not be directly exposed to rainfall. Place the device in a semi-sheltered location (e.g., under an awning, eave, or balcony cover) while positioning the leak sensor cable where it can be exposed to rain for accurate detection.
