Learn how to diagnose and troubleshoot when a newly installed soil moisture sensor is no found on a two-wire system.

At the Controller

• Turn the dial to Assign.
• Open the device you want to assign (ex. Zones).
• Search should be highlighted → Enter.
• Once search completes, the left panel shows found serial numbers from wire path.
• Move the correct serial number to the right side to assign, Q245151 → Zone 1.
• If a serial number (Q245153) doesn’t appear, it may already be assigned.

Soil Moisture Sensors

• Open Moisture Sensors → highlight Search → press Enter.
• If the sensor isn’t found, go out to the field and carefully dig it up.
• Carefully dig up the sensor.
  • We do not want to cut the wire to the short.
  • Remove the wire all the way back to the box where the original splice was made.
• Splices should be in a pull box with at least 18” of slack.
  • Industry standard call for splices to be made in a pull box.

Direct Sensor Test at Controller

• Now test the device back at the controller.
• Power down the controller (unplug, switch breaker, or remove orange plug).
• Disconnect the existing two-wire path from terminals.
• Connect the moisture sensor directly to the red and black terminals.
• Power the controller back on and try assigning the sensor again.
• If the controller finds it now, the issue is likely in the wire path or splices.

Wire Troubleshooting

• Check splices, wire integrity, or damage.
• If still not detected, the sensor may be faulty.
• Contact Baseline support to check warranty eligibility.
