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.

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.
Does the DIG LEIT-1 require direct sunlight to charge?
No, the DIG LEIT-1 is powered by ambient light. It does not require direct sunlight and can capture enough energy from surrounding daylight in any weather condition to operate flawlessly.
However, it must be installed above ground where ambient light is present; it cannot be buried inside a dark underground valve box.
Do I ever need to replace batteries in the LEIT-1?
No! The LEIT-1 is a fully self-sustainable irrigation controller. It utilizes an internal photovoltaic system powered by ambient light, completely eliminating the need for alkaline or lithium batteries.
This provides 100% maintenance-free power for the entire lifespan of the controller.
Will the DIG LEIT-1 work with my existing irrigation valves?
Yes, the LEIT-1 comes with a 7-12 VDC two-way latching solenoid and specific adapters that allow it to easily retrofit onto most standard Rain Bird, Hunter, and Toro valves.
Simply unscrew the old AC solenoid on your valve and replace it with the newly provided DC latching solenoid.
How should I prepare my DIG LEIT-1 for spring watering?
Prepare the DIG LEIT-1 for spring by verifying your wire connections and manually testing the valve operation. Because it features SimpleSmart™ programming, the controller will automatically adjust your schedules based on historical spring ET data.
This smart capability prevents overwatering during the cooler, wetter months of early spring.
