K-Rain BLUE-1 Bluetooth Battery Powered | 1-Station Waterproof Timer

Product Details

The K-Rain BLUE-1 is a heavy-duty, single-station irrigation controller designed for remote locations where electrical power is unavailable. This rugged, battery-operated timer is managed entirely via the free K-Rain BLUE App on your smartphone or tablet, utilizing secure Bluetooth technology for wireless programming. With an IP68 waterproof rating, the BLUE-1 is fully submersible and designed to be installed directly inside a valve box. It is the perfect solution for isolated flower beds, highway medians, and greenhouse applications where traditional wiring is impossible or cost-prohibitive.

• Cloud-Based Backup: Your settings and programs are stored in the cloud via the K-Rain app, allowing for easy recovery if your phone is replaced.

Installation & Maintenance Tips:

• App Setup: Download the K-Rain BLUE app (iOS or Android), enable Bluetooth, and use the "Add Controller" function to sync your device.
• Testing: Use the "Manual Start" feature in the app to test your valve and check for leaks immediately after installation.

Common Uses/Applications:

• Greenhouses & Nurseries: Provides independent control for specific benches or propagation areas without complex wiring.

Common Questions:

Q: Can I lock the controller so others can't change it?

A: Yes. You can set a unique passcode for the controller within the K-Rain app to prevent unauthorized access in public spaces.

Q: Does it work if my phone isn't nearby?

A: Yes. Once the program is uploaded via Bluetooth, the BLUE-1 stores the schedule internally and will run automatically. Your phone is only needed for setup or changes.

Q: What happens to my program when the battery dies?

A: The controller features non-volatile memory that retains your schedule. Once a fresh battery is installed, the clock will need to be synced via the app, but your settings will remain.

The K-Rain BLUE-1 combines the convenience of smartphone control with the ruggedness of a fully submersible timer, offering a smart solution for every remote zone.
