Rain Bird ESP-BAT-BT Battery Powered Irrigation Controllers with Bluetooth & Mastervalve Input

FEATURES

• Bluetooth Control: Program, start, stop, or test irrigation directly from your smartphone with the Rain Bird 2.0 App.
• Extended Battery Life: Runs up to 3–5 years on four AA batteries, with predictive power management and low-battery mapping.
• Waterproof Design: IP68 rating ensures protection against dust, dirt, and full water immersion—even in flooded valve boxes.
• Cycle & Soak™: Run-off management down to 7-second cycles, reducing water waste.
• Flexible Scheduling: Four independent programs (A–D) with eight start times per day, global seasonal adjust (0–200%), and permanent/custom days off.
• Smart Mapping & Sharing: View controller status, battery levels, and program data; securely share access with your team.
• Resilient Performance: Built-in capacitor stabilizes operation during voltage dips, extreme temperatures, and long wire runs

APP FEATURES

• Advanced Mapping: Map pins turn red when battery is below 30%. Select a mapping pin and access commonly used shortcuts: manual water, edit controller, battery status, controller sharing, change address, Bluetooth status and delete device.
• Offline Mode: Edit, track, and save desired controller changes in the app, even when out of Bluetooth™ range. Review change log at anytime. Rapid synchronize change log when back on site and in Bluetooth™ range.
• Controller Sharing: Streamline operations and collaboration with your team. Share secure access of any and all devices with new team members. Keep existing team members up-to-date with on-site controller changes or make offline changes from anywhere and share with a team member on site for synchronization, saving a site visit.
• Monthly Seasonal Adjust: Seasons change and so should your water schedule. Program adjustment values by month for the entire year in advance, saving not just water but site visits.
• Cycle & Soak™: Eliminate runoff, a common form of water waste by breaking up the total run time into shorter cycles so the soil has time to soak in the water (available down to 7 second cycles).
• Seconds Based Irrigation: Run times go down to 7 seconds allowing one second intervals (7 seconds to 18 hour run times).
• Calendar Days Off: Have a future event in the park and you want to be sure irrigation doesn’t run? Schedule the day(s) off ahead of time, saving a site visit.
• Permanent Days Off: Do you always mow on Thursdays? Exclude certain day(s) of the week on a recurring basis, no matter the chosen watering frequency. (Odd, Even and Cyclic)
• Additional Images: Quickly identify stations and sites via custom imagery.
• Interstation Delay: Allow a delay between a station turning off and another turning on. This ensures your hydraulics are never compromised.
• Rain Delay: Is rain coming? Save a site visit, turn the controller off for up to 14 days and then auto-resume irrigation. If rain is expected for more than 14 days set Monthly Seasonal Adjust values to 0%.
• Pause Active Irrigation: If and when a broken nozzle occurs, simply pause the station, fix the issue and resume right where the irrigation program left off.
• Search & Filter: Easily find controller(s) right from the home screen. Sort by name, controller type, recently added or last connected. Filter by Bluetooth in range, sync available or low battery.
• Controller Grouping: For sites with multiple battery-operated controllers, add multiple controllers to a group for organized on-site operations.
• Quick Status: View all your connected controllers and their most relevant statuses: controller auto, controller off, rain delay, calendar day(s) off, battery life and Bluetooth connection.

APPLICATIONS

• Remote Irrigation Sites: Ideal for valve boxes, sports fields, medians, and other locations without AC power.
• Residential & Commercial Landscapes: Flexible station models allow precise irrigation scheduling across multiple zones.
• Harsh Environments: Waterproof design and capacitor-powered reliability ensure performance in flooded boxes, dusty soils, and extreme climates.
• Team-Based Management: Contractors and maintenance teams benefit from controller sharing, offline programming, and predictive battery insights that reduce unnecessary site visits.
