Brand: K-Rain SKU: BLUE-2
Product Overview
The K-Rain BLUE-2 is a two-station, battery-powered irrigation controller for remote valve boxes and landscape areas where running AC power or multi-conductor controller wire is difficult or cost prohibitive. It independently controls two irrigation valves and is programmed through the K-Rain BLUE app using a direct Bluetooth connection from a compatible smartphone or tablet.
The waterproof IP68 enclosure is designed for installation directly in a valve box. Its UV-resistant, high-impact construction supports demanding outdoor locations such as medians, roundabouts, remote gardens, nursery areas, and landscape additions separated from the main controller. K-Rain specifies manual Bluetooth operation from up to approximately 35 feet under suitable conditions and app functions that include mapping, passcode protection, battery indication, water-budget adjustment, and program backup.
Both controlled valves must use compatible 9V DC latching solenoids. Standard 24 VAC valve coils are not compatible with this battery-operated output. BLUE-2 can also accept a normally closed rain or rain/freeze sensor when wired according to the current manual. Confirm battery requirements, solenoid type, wire distance, and enclosure sealing before placing the controller into service.

Frequently Asked Questions
How many valves can BLUE-2 control?
It independently controls two stations or valves.
Can it operate standard 24 VAC solenoids?
No. Compatible 9V DC latching solenoids are required.
Is the title's “1-station” wording correct?
No. BLUE-2 is the two-station model; the live title contains legacy wording that should not be used to select capacity.
Why Buy the K-Rain BLUE-2 from Big Frog Supply?
This page corrects the one-station title conflict and clearly identifies BLUE-2 as the two-valve model. Big Frog Supply also carries compatible latching solenoids, irrigation valves, rain sensors, and waterproof connectors for building a complete battery-powered two-zone system.
