Dear customer,

May I inquire if this "5 seconds on, 1 min off" pattern occurs consistently during watering, or is it an occasional issue? Also, could you please let us know when this behavior started? Please press and hold the reset button for 8 seconds to do a hard reset to reset the unit to see if it works.

1.Power off the device(unplug the power adapter)
2.Wait for 2 seconds, replug the power back in
3.Wait for 3 minutes for the device to start up
4.Press and hold the reset button for 8 seconds to do a hard reset
5.Wait for 3 minutes. This should set the light to slow blinking.

Thanks,

Netro Support
