🏠 Finally, a simple way to protect your home from water damage & temperature disasters

Ever worried about your washing machine hose bursting while you're on vacation? Or your basement flooding from a hidden pipe leak? One incident can cost thousands in repairs and destroy cherished belongings.

The Elitech RCW-800W is your 24/7 home guardian. It combines a high‑precision temperature/humidity sensor with a 33‑foot (10m) water leak detection cable. Simply place the cable near potential leak sources (water heater, sump pump, dishwasher) and the main unit anywhere you like. If water touches the cable, or if the temperature/humidity goes outside your preset range, you'll get instant alerts via app push, text message, email, and a loud 85dB audible alarm.

✅ FDA 21 CFR Part 11 compliant data logging – secure cloud storage with audit trail (great for home businesses or medical storage).

Note: Restart the device after connecting the external probe to ensure proper initialization.
