Troubleshooting Guide

If you’re experiencing an issue with your STA device, the information below may help you resolve it before contacting support.

Each section describes a common issue, followed by the most likely causes and suggested solutions.

The bold text is a description of the issue.

• The dot points underneath are the cause – Followed by a description of the solution in italics.

STA device won’t turn on.

• The trigger mechanism or attachment is not connected correctly – Ensure the trigger mechanism is correctly fitted to the sprayer and moves freely when the spray trigger is pressed.
• The trigger cable is not connected to the STA device – Connect the trigger attachment to the STA device and press the spray trigger to wake the unit.
• The battery is flat – Fully charge the device before use. Ensure you are using a charging cable rather than the configuration cable.
• Hardware fault – If the above steps do not resolve the issue, contact support for assistance.

The device worked correctly in the field, but no data appears in the web app

• Upload error – Something is causing an Upload error. Refer to the next section.
• Cloud processing issue – Occasionally there may be an issue processing uploaded data. Contact support with the device name and the date(s) of the missing data.

The device reports “Upload Error” or is stuck on “Uploading”

• Incorrect WiFi credentials – Verify that the stored WiFi network name and password are correct.
• Poor WiFi signal – Uploads are most reliable when the device is close to the wireless router. Walls, buildings and long distances can cause brief interruptions that result in failed uploads.
• Poor internet connection – Slow or unstable internet connections may prevent uploads from completing successfully. Try uploading using a reliable broadband connection.
• Network security restrictions – Some organisations have firewalls or network security policies that prevent unknown devices from communicating with the internet. If you’re using a managed network, speak with your IT provider.
• Incorrect WiFi band – STA devices support 2.4 GHz WiFi networks only. They cannot connect to 5 GHz-only networks. If your router broadcasts separate 2.4 GHz and 5 GHz networks, ensure the device is configured to use the 2.4 GHz network. If your router combines both bands under a single network name (band steering), you may need to enable a dedicated 2.4 GHz network or temporarily disable band steering while configuring the device.
• Country or regional restrictions – In some countries or regions, local network restrictions may interfere with cloud connectivity. If you suspect this is the case, please contact support.

A continuous spray zone is being recorded

(Appears as a long “worm” beneath the tracklog.)

• The trigger mechanism is being held slightly pressed – Adjust the trigger mechanism so it is only activated when the spray trigger is intentionally pulled.
• Hardware fault – Contact support if the trigger mechanism appears to be operating correctly but the problem persists.

Test data appears inaccurate or scattered

• Poor GNSS/GPS reception – Ensure the device has a clear view of the sky during testing. Do not test indoors. Allow approximately 30 seconds after powering on each morning for the initial satellite fix. After the first fix, satellite acquisition is much faster throughout the day.

Location accuracy appears poor

• Poor GNSS/GPS reception – Ensure the device has an unobstructed view of the sky. Avoid using the device indoors or beneath heavy tree canopy where possible. Allow sufficient time for the initial satellite fix each day.
• Imagery basemap offset – Most online imagery basemaps are not perfectly aligned with true ground position. Small offsets are normal and do not necessarily indicate poor GPS accuracy.

If you would like advice on assessing GPS accuracy in your area, contact support.

The device keeps beeping and is unresponsive

• If the screen is damaged or unavailable, the STA device communicates its status using beep sequences – Count the number of beeps in each repeating sequence (between one and nine, or continuous). Contact support and let us know the number of beeps you hear.

The screen displays “SD Card Error”

• The SD card has become dismounted or has developed a fault – Contact support. We can guide you through checking, remounting, testing the SD card or sending back for repair.
