A Low Current notification means the controller has measured low current in the wiring to the valve in a particular zone. When the zone finishes the cycle, you will receive an alert that says LOW CURRENT DETECTED (i.e., Hydrawise waits for the cycle to finish to verify if there is any current). This alert is usually the result of an OPEN WIRE CIRCUIT or DAMAGED SOLENOID.
The LOW CURRENT message will display in the Events log as a warning or through an alert (if set) if Hydrawise detects the current in a range between 0–70 mA. Model HC-600i does not have the current-sensing option.
IMPORTANT: Do not attempt to test this alert by connecting a faulty or damaged solenoid. Doing so can cause the controller to malfunction.

Basic Troubleshooting
- Use a Phillips screwdriver to remove the wire from the zone terminal that is receiving the message.
- Turn on the zone manually at the controller or using the Hydrawise app.
- If the zone appears to run normally from the controller (with no water flowing), then you will need to inspect the field wiring and solenoid.
- Field wiring: Verify the solenoid is properly connected with no open-wire connections.
- Solenoid: Test the solenoid by wiring straight to the controller and turning the zone on manually (e.g., com terminal and Zone 1).
- Using devices like solenoids from other manufacturers or low-voltage lighting relays may cause this alert as well. The system will run normally but you will continue to receive the alert.
