iGrow 800 Temp Probe Fluctuating issues

Please take the following steps in troubleshooting your Temperature Probe.
 
·        iGrow 100 Series Sensor Troubleshooting

 
  1. Check connection’s inside junction box (if one exists) for moisture or corrosion
  1. Check the PCB for corrosion, moisture or contamination build up.
  1. Check the line that leads to that box for cuts or any damage which will affect the sensors readings.
  1. Check for wire any interference sources (voltage, motors, inverters, etc….)
  1. Cycle equipment ON and OFF and see if Sensor Reading appears or Stabilizes
  2. Check the power supply P/S and see if dropdown voltage AC to 12VDC is accurate.
o   Since incorrect voltage can discourage the logic within the device.

Try powering iGrow from a different circuit entirely (extension cord across the way or an inverter) and see if the sensor stabilizes
Sensor Reading Jumping Around and not constant.
Do troubleshooting steps first – when it JUMPS that indicates some type of Interference.
·         Try toggling OFF outputs 1 by 1 until all are OFF to see if sensors STABLIZES.
·         NEXT, toggle them ON to see if a power change creates fluctuation. 
·         Try powering iGrow from a different circuit entirely (extension cord across the way or an inverter)
·         If controllers are Daisy Chained to one 12V source, try powering 12V independently. With an additional P/S
·         How longs the Sensor wire  (150ft max)
·         Who spliced the wire?
·         Is the shield grounded?
IF ALL ELSE FAILS THERE ARE 3 OPTIONS AVAILABLE
-          Use a shielded cable
-          Install a filter PCB at the iGrow
-          Use a digital temp/hum sensor
