Issue

 Reason

 Solution

Consistent 0% value in the sensor data

Sensor pins not making proper contact with the soil

Remove sensor, shake it, and reinstall in the soil in a different spot.

Do not wiggle sensor back and forth when inserting as this can create a void and prevent proper soil contact. 

The integrity of the sensor compromised (crack or break)

Usually caused by excessive force during installation.

If delivered this way, device will be replaced. If caused by the user, the issue will need to be investigated. Sensor may be replaced and advice given on proper installation method: Push sensors into the soil but stop pushing should you feel resistance. In rocky soils, tap in with a rubber hammer.  Stop tapping should you feel resistance and find a better installation location.

No data from sensors farthest from the gateway

Range may not be optimal or signal may be obstructed.

Move sensors closer to the gateway or reinstall them at the same location but leave them sticking out of the ground 5-10 cm (2-4 in) to improve range.

Sudden linear drop or rise in soil moisture value.

Soil type for the sensor has been changed. 

Historical data is not changed to reflect the new selected soil type. New calibrated data is shown after soil type is changed.

Soil moisture values not changing after rain

Depending on the soil type, the depth of the sensor, and the quantity of rain, changes in soil moisture may not register immediately if at all.

• Manage client expectations. Clay soils hold water longer and are slower to show changes in value under average conditions. Sandy soils can drain water away quickly. 
• Use the soil moisture interpretation guide to educate clients about soil moisture values. 
• If a client is suspicious of readings from one sensor, have them use two sensors at the same location and depth to compare and test readings.

Unexpected high soil moisture values 

High salt content or EC values of the soil may have an impact on soil moisture readings.

User can create their own adjusted thresholds based on knowledge and experience with soil moisture. A soil analysis will show salt and EC values.

No data from any sensor

Gateway outage

Check the power supply or internet cable/antenna connection.

No data from sensors

• Signal may be obstructed.
• Gateway might be down

• Reinstall sensors at the same location but leave them sticking out of the ground 5-10 cm (2-4 in). Move away from any obstacles like grain silos, high-power-lines, dykes, etc.
• Reassess distance to the gateway if the problem continues. 
• Check gateway health
