iGrow 800 Common Weather Station Sensor Problems and How to Fix Them

This article describes common sensor-related issues that may occur with the iGrow weather station and provides recommended actions to help restore accurate and reliable readings.

One or More Sensor Readings Are Missing or Blank

If a sensor value is not appearing on the display, it is usually due to an incorrect configuration.
Action: Verify that the menu mapping is set correctly and that each sensor is properly assigned within the controller settings.

Temperature Sensor Reading Is Jumping or Unstable

Fluctuating temperature readings are often caused by improper wiring or poor electrical connections.
Action: Confirm that a high-grade, shielded, stranded 22 AWG wire was used during installation, as other wire types may cause unreliable readings. Also, verify that all wire terminations in both the junction box and the iGrow controller are tight and secure.

No Wind Speed Is Detected

A lack of wind speed data is typically related to the physical installation of the sensor.
Action: Ensure that the wind cups are fully pressed into place and properly seated.

Rain Sensor Is False-Triggering

False rain events usually indicate loose wiring or stray wire strands.
Action: Check that all wiring terminations are tight and that there are no loose or exposed wire strands in the junction box or inside the iGrow controller.

Light Reading Is Low During the Day

Low daytime light readings are commonly caused by obstructions near the sensor.
Action: Make sure there are no shadows cast on the light sensor and that it has a clear, unobstructed exposure to sunlight.
