Support: HY485 6-in-1 Hydroponic Monitor

Product: Rovynel HY485 6-in-1 Hydroponic Water Quality Monitor
SKU: RVN-HYDRO-6IN1
Device type: Combined air and nutrient-water monitor

What it measures

Exactly six conditions: air temperature, air humidity, pH, water temperature, EC, and TDS. It does not measure ORP, salinity, specific gravity, or free chlorine.

Connection

The monitor uses a 2.4 GHz WiFi network for Tuya app readings and alerts.

Quick start

  1. Identify the air sensor and water probes before installation.
  2. Place each sensor only in its intended air or nutrient-water location.
  3. Power the system and confirm local readings.
  4. Connect to 2.4 GHz WiFi and the Tuya app.
  5. Complete model-specific pH and EC preparation or calibration.
  6. Observe a stable baseline before setting alerts for a crop or growth stage.

Troubleshooting

  • pH or EC drift: inspect probe fouling, solution mixing, temperature, calibration, and reservoir changes.
  • Air readings differ: compare sensor height, airflow, radiation, and distance from humidifiers or lights.
  • App is offline: confirm 2.4 GHz WiFi coverage and reconnect the display.
