Every time you connect to ESP-BAT-BT, the Rain Bird 2.0 App receives the controller’s current battery status. After you leave the site, predictive battery monitoring uses the controller’s programming and last known battery information to estimate how the batteries are being depleted over time. The app makes it clear whether you’re viewing a current or […]

ESP-BAT-BT operates stations sequentially, so stations do not run at the same time. If a scheduled watering start occurs while irrigation is already running, the additional watering is added to the watering queue rather than running simultaneously. Once the current watering finishes, the queued irrigation can run in order. This prevents overlapping schedules from attempting […]

When you’re not within Bluetooth range, the Rain Bird 2.0 App can still show the controller’s last known information from the most recent connection, including information such as battery and controller status. Because ESP-BAT-BT is a Bluetooth controller, Last Known Status is not live remote monitoring. Information is updated the next time someone connects to […]

If you’re having trouble connecting: Make sure Bluetooth is enabled on your mobile device.

Yes. Once your irrigation programming has been synchronized to ESP-BAT-BT, the controller operates independently. Your phone does not need to remain connected by Bluetooth for scheduled irrigation to run. Bluetooth is used when you want to connect to the controller to synchronize changes, view current information, or perform controller actions.

ESP-BAT-BT includes several scheduling options that let you plan watering restrictions and shutdowns in advance. In each case, the controller automatically returns to its normal schedule when the restriction ends, eliminating the need for another site visit. Permanent No-Water Days: Prevent watering on a specific day of the week even when using an interval schedule—for […]

There are several ways to quickly find the controller you need in the Rain Bird 2.0 App: This is especially useful on sites with many controllers, where scrolling through a long controller list may not be the fastest way to find the device you’re standing next to.

You can make changes to a controller in the Rain Bird 2.0 App even when you are not within Bluetooth range. The app will save the changes until they can be synchronized with the controller. When you’re ready, share the controller with the person who will be on site. What happens next depends on whether […]

Yes. Some third-party 9V DC-latching solenoids may have electrical characteristics that cause ESP-BAT-BT to detect a potential wiring issue. The solenoid may still operate normally even when a warning is detected. If a wiring warning appears when using a third-party solenoid, first verify the wiring and connections are secure, then manually run the station to […]
