Ambient Light Powered Single-Station Irrigation Control
The DIG LEIT-1 Ambient Light Powered Timer is a revolutionary, fully self-sustainable single-station irrigation controller. Powered entirely by surrounding ambient daylight, it requires absolutely no direct sunlight, zero AC power, and no batteries to operate. This makes it the ultimate maintenance-free automation solution for remote gardens, median strips, and off-grid landscapes. Out of the box, it comes complete with a DC latching solenoid and specialized adapters to easily retrofit existing Rain Bird, Hunter, and Toro irrigation valves.
Beyond its innovative, battery-free power source, the LEIT-1 features a highly intuitive LCD screen and seven-button keypad for easy programming. It utilizes DIG’s SimpleSmart™ programming, which automatically adjusts your irrigation schedules monthly based on historical Evapotranspiration (ET) data, eliminating over-watering and under-watering. With 5 start times per day, custom watering intervals, and a dedicated connection for rain or moisture sensors, this ambient light timer delivers smart, commercial-grade water conservation wherever you need it.
- Ambient Light Powered: Operates flawlessly in any weather condition using just surrounding light—no batteries or AC electrical power required.
- Universal Valve Adapters: Includes a DC latching solenoid and adapters to securely fit most standard Rain Bird, Hunter, and Toro valves.
- SimpleSmart™ Technology: Automatically adjusts your watering schedules monthly based on historical ET data to maximize water savings.
- Advanced Scheduling: Offers 5 start times per day, 1-minute to 5-hour 59-minute durations, and weekly, odd/even, or interval programming.

Get your battery-free irrigation controller running in a few simple steps.
Step 1: Install the Solenoid
Remove your valve’s existing AC solenoid. Thread the included DIG DC latching solenoid onto the valve, utilizing the provided adapters for Rain Bird, Hunter, or Toro valves if necessary.
Step 2: Mount the Controller
Attach the LEIT-1 controller to a post, wall, or directly onto the valve using a compatible mounting bracket. Ensure the top of the controller receives ambient daytime light (do not bury it in a dark valve box).
Step 3: Connect the Wires
Splice the two wires from the LEIT-1 controller directly to the two wires on the newly installed DC latching solenoid. Always use silicone-filled waterproof wire connectors to prevent corrosion.
Step 4: Program the Timer
Use the seven-button keypad and integrated LCD to set the current time, date, and your desired watering schedules. Enable the SimpleSmart™ feature to allow the timer to automate seasonal adjustments.
