WWD 241 Smart Water Detector with Float Switch

WWD 241 Smart Water Detector – Your Level Monitor with Mobile Alert for Water & Oil

Water, heating oil, or diesel is rising – your smartphone knows immediately. The WWD 241 from Elektrotechnik Schabus combines a proven mini float switch (from approx. 4 cm level) with smart Wi-Fi technology: in the event of an alarm, it sounds a loud 90 dB siren, flashes red, and simultaneously sends you a push notification via the free Smart Life app – no matter if you’re in the office or on vacation.

Once the liquid level drops again, all signals stop automatically and the app reports “all clear.” Detects liquids from 0.7 g/cm³ – perfect for heating oil tanks, collection trays, sump pits, and cisterns. Supplied with 2.5 m LIYY cable (extendable up to 50 m), mains-powered, and easy to set up. The smart professional that works reliably even with dirt and oil.

The technology is robust as is typical for Schabus – now made smart: a genuine float switch instead of a sensitive fork sensor – no false alarms caused by dirt or oil films. The loud signal generator is built directly into the plug-in unit, with automatic reset and a stable 2.4 GHz Wi-Fi connection. LIYY cable is flame-retardant, oil-resistant, and temporarily waterproof. Made in Germany – now with push notification for everyone who wants to avoid unpleasant surprises.

The WWD 241 is more than just a detector – it’s your mobile tank and basement guard. Landlords, vacation home owners, heating oil users, and anyone with a sump pit or collection tray appreciate the combination of loud on-site alarm and instant smartphone notification – especially when no one is around. Once plugged in and set up, it monitors 24/7 and keeps you informed wherever you are.
