Shelly Flood Gen4 WiFi-Operated Smart Flood Sensor Setup Guide

Shelly Flood Gen4 WiFi-Operated Smart Flood Sensor

  • Tools required:
    • Smartphone with internet access (for app and Wi‑Fi setup)
    • Soft cloth and isopropyl alcohol (clean mounting surface)
    • Screwdriver or double-sided adhesive pads (depending on chosen mount)
    • Small flat tool or fingernail to open battery compartment, if fitted
  • Applications:
    • Shelly mobile app (manufacturer configuration) — app name/availability not specified
    • Smart-home controller or hub app for integrations (optional) — compatibility and required apps not specified

 

  • 1. Unpack and inspect: Remove the sensor from packaging and inspect visually. Ensure the unit and any included mounting hardware or adhesive pads are present. Do not submerge the unit during inspection.
  • 2. Identify connectivity and capabilities: The product title explicitly states Wi‑Fi operation. Any other protocols (Bluetooth, Zigbee, Matter) appear as tags but their availability or role in setup is not specified. Configure using Wi‑Fi unless manufacturer documentation you possess states otherwise.
  • 3. Prepare the mounting location: Choose a location where leaks or water pooling are likely to occur (e.g. near a washing machine, below a hot-water cylinder, under sinks, in basements). Clean the surface with a soft cloth and isopropyl alcohol and allow to dry. Ensure the sensor probe/contacts will make contact with possible water flow.
  • 4. Install battery or power up: If the unit uses an internal battery, open the compartment gently and insert batteries following the polarity marking. If batteries are preinstalled, confirm any battery isolation tab is removed. If the device uses an external power option, refer to the manufacturer instructions — high-voltage wiring is not described here.
  • 5. Download and open the required app: Install the Shelly mobile app on your smartphone if available. If you have another app required by your smart-home controller, have it ready. Sign in or create an account if prompted (account creation steps are not specified here).
  • 6. Put the sensor into pairing/configuration mode: Follow the manufacturer app prompts to add a new device. If the sensor requires a physical action to enter pairing (pressing a button or removing an isolation tab), do that now. Exactly how to enter pairing mode is not specified here; follow app instructions when prompted.
  • 7. Connect to Wi‑Fi: Use the Shelly app (or the app directed by the device) to connect the sensor to your Wi‑Fi network. Only Wi‑Fi is explicitly specified by the product title; do not assume support for specific Wi‑Fi bands (e.g. 2.4 GHz) unless the app or supplied documentation states it. When prompted, select your network and enter the password.
  • 8. Confirm successful pairing and name the device: After configuration, the app should show the sensor as online. Assign a clear name and location (e.g. "Basement - Boiler"), so alerts identify the area of the leak.
  • 9. Mount the sensor: Secure the sensor using adhesive pads or screws as appropriate. Place the sensing edge or probes at the lowest point where water would first appear. Avoid mounting higher than surfaces you want to monitor; most flood sensors must make direct contact with water to trigger.
  • 10. Test the sensor and alerts: Use the app’s test function if available. If no test function exists, place a few drops of water on the sensing contact to verify an alert is triggered and that push/notification alerts are received on your smartphone. Dry the sensor immediately after testing.
  • 11. Integrate with other systems (optional): If you plan to integrate the sensor into a wider smart-home system, consult your controller’s integration steps. The device title confirms Wi‑Fi operation; whether direct Matter, Zigbee or Bluetooth integration is supported is not specified here and must be confirmed in manufacturer documentation.
  • 12. Maintenance and checks: Periodically check battery status in the app and replace batteries as indicated. Clean the sensing contacts occasionally to remove debris. Re-test alerts after any firmware updates or relocated mounting.
  • 13. Troubleshooting: If pairing fails, ensure your smartphone is on the same Wi‑Fi band and within range, restart the app, reboot your router if necessary, and retry following the app prompts. For persistent issues, consult official Shelly support documentation — specifics are not provided here.
  • 14. Important safety notes: This guide covers only physical and wireless setup steps. Do not expose the sensor electronics to prolonged immersion beyond brief testing drops. If you encounter any instructions that require mains wiring or high-voltage work, have a trained electrician perform those tasks; mains work is not described in this guide.
