Support: 7-in-1 WiFi Water Quality Monitor

Product: 7-in-1 WiFi Water Quality Monitor with App Alerts
SKU: RVN-WQ7-WIFI
Device type: Complete seven-parameter monitor

What it measures

pH, ORP, TDS, EC, salinity, specific gravity, and water temperature. It does not measure free chlorine.

Two connection layers

A long-range wireless link carries readings from the sensor to the display. Separately, the display uses 2.4 GHz WiFi to connect to the Tuya app.

Quick start

  1. Prepare the sensor and display using the supplied model instructions.
  2. Pair or confirm the long-range sensor-to-display link.
  3. Place the sensor in a representative water location and the display where it remains dry and visible.
  4. Connect the display to 2.4 GHz WiFi and the Tuya app.
  5. Complete model-specific calibration and confirm stable readings.
  6. Set alerts only after you understand the normal range and expected daily variation for the application.

Troubleshooting

  • Display has no sensor data: troubleshoot the long-range sensor link, power, distance, and obstacles.
  • App is offline: troubleshoot 2.4 GHz WiFi near the display.
  • Readings jump: inspect bubbles, fouling, placement, stabilization time, and calibration.
