The Hunter NODE-BT 1-Station Bluetooth Controller with Solenoid brings highly advanced, professional-grade irrigation management directly to your smartphone. Designed for remote gardens, greenhouses, and landscape sites where running AC power is impossible, this battery-operated timer provides complete automated control over a single valve station. To ensure reliable performance from your controller's new solenoid, we highly recommend installing a water filter upstream to prevent debris from causing the valve diaphragm to stick open.
Built with Hunter's legendary ruggedness, the NODE-BT features a completely waterproof exterior capable of handling any weather condition, allowing it to be installed directly inside a muddy, subterranean valve box. Using the free smartphone app, you can easily program up to 3 separate schedules with 8 start times each, and adjust watering durations from a precise 1-second burst up to a full 12 hours. Even without your phone, a convenient manual push-button on the unit allows you to initiate immediate watering. Powered by either one or two 9-volt batteries, it is the ultimate standalone solution for isolated irrigation control.

Follow these steps to properly install and program your new Hunter controller.
Step 1: Install Batteries
Open the waterproof battery compartment and insert one or two fresh 9-volt industrial alkaline batteries. Secure the cap tightly to maintain the waterproof seal.
Step 2: Connect the Solenoid
Thread the included DC latching solenoid directly into your compatible Hunter valve body. Splice the solenoid wires to the controller wires using waterproof wire nuts.
Step 3: Download the App
Search for the Hunter "NODE-BT" app in the Apple App Store or Google Play Store. Download it to your Bluetooth-enabled smartphone.
Step 4: Pair and Program
Stand within range of the controller, open the app, and follow the prompts to pair the device. Set your desired watering days, run times, and start frequencies.
Can I run this timer without my smartphone?
Yes, the NODE-BT features a manual push-button on the controller face. This allows you to quickly start or stop a watering cycle directly at the valve without needing your smartphone.
This is especially helpful for quick system testing or if a landscaper needs to manually turn on the water while your phone isn't nearby.
How many batteries does it require?
The unit operates on a single 9-volt alkaline battery, but it features a dual-battery compartment. Installing two 9-volt batteries will significantly extend the operational life between replacements.
We recommend using two high-quality name-brand batteries, especially in extreme temperatures, to ensure a full season of reliable automated watering.
Is the controller fully waterproof?
Yes, the Hunter NODE-BT features a rugged, fully waterproof exterior. It is designed specifically to withstand harsh outdoor conditions and can be safely installed directly inside an underground valve box.
To maintain this waterproof rating, always ensure the battery compartment cap is tightly secured and that waterproof wire nuts are used on all splices.
Can I use this on a 24V AC irrigation system?
No, this controller and the included solenoid are designed exclusively for 9V DC battery operation. It cannot be hardwired into a traditional 24V AC residential sprinkler system transformer.
If you have a hardwired system but want to convert a specific remote zone to battery operation, this unit will replace the AC solenoid on that specific valve.
