Bluetooth and connectivity

You get local wireless control rather than cloud-based access, so you don’t need Wi-Fi or cellular service. That means you retain control when you’re within the Bluetooth range and avoid ongoing subscription fees, but you’ll need to be physically nearby to make changes.

Because the range is listed as up to 50 feet line-of-sight, you’ll usually connect easily from your patio or driveway to a backyard unit, though walls or other obstructions will reduce that range. The app interface makes programming quick and intuitive, and the ability to manage unlimited controllers from one device is helpful if you maintain multiple properties or spread-out irrigation zones.

Waterproof design and durability

The NODE-BT-100-LS features a fully waterproof enclosure to protect it from rain, sprinklers, and damp greenhouse conditions. This helps you avoid the need for extra weatherproof boxes or constant concern about moisture ingress.

Nevertheless, even waterproof enclosures perform better if mounted under some cover or in a location where direct high-pressure water streams don’t hit the face of the controller. Positioning it thoughtfully keeps seals happy and extends useful life.

Power and battery considerations

This controller is battery operated, so you don’t have to run electrical power to a box near the valves. That can save installation time and permit placement in remote or fenced areas. It uses standard batteries (follow the manual for exact type and quantity), and the battery-life LED gives you a visual cue that replacement is approaching.

Battery life depends on how often you run stations, how many solenoids you energize, ambient temperature, and battery quality. In many typical residential uses, you can expect months to a year of service before replacements are needed—but heavy use, frequent Bluetooth sessions, or cold climates can lower that. It’s smart to replace batteries seasonally or whenever the battery LED warns you.

Note: The listing states DC solenoid is not included, so you’ll need to ensure compatibility with your valve solenoids or purchase compatible DC latching solenoids if required.

Programming and scheduling flexibility

You can run three separate programs with up to eight start times each. That’s plenty for most residential setups: you can have a program for rotors, another for drip, and a third for specialty zones like a greenhouse bench.

Run times range from a single second to 12 hours, which gives you fine control for anything from brief pulse irrigation events to long soak cycles for large planters or water-hungry trees. The Cycle and Soak feature lets you split long run times into shorter cycles, reducing runoff on slopes and improving infiltration in compacted soils.

The Suspend function lets you pause watering for up to 99 days, which is handy when you’re traveling, facing an extended rainy period, or during winter dormancy. Monthly and global seasonal adjustments help you change run times by percentage across the entire controller, so you don’t have to edit every station when rainfall patterns shift.

Manual operation and LED indicators

When you don’t want to use your phone, the manual push-button operation lets you start or stop stations directly at the unit. This is helpful during installation, maintenance, or when you need to quickly test a valve.

Active station LEDs show you which stations are operating, and the battery-life LED signals when it’s time to swap batteries. These straightforward indicators remove guesswork and simplify ongoing maintenance.

Sensor support and compliance options

You can add a soil moisture sensor to the NODE-BT series for smarter irrigation control and to meet certain LEED or agricultural project requirements. A sensor helps you water only when the soil needs it and reduces waste.

Installing a compatible sensor gives you automation beyond time-based schedules and helps you adjust irrigation during wet spells or droughts without constant manual intervention.

Cycle and Soak, Seasonal Adjustment, and Suspend

Cycle and Soak prevents waste and runoff by breaking one long program run into a series of short runs with soak intervals between them. This is especially valuable with tight or sloped soils where water needs time to move into the root zone.

Global and monthly seasonal adjustments provide a fast way to increase or decrease run times by a percentage across all stations, which is a real time-saver during seasonal transitions. Suspend lets you stop watering for a set period up to 99 days without deleting programming—handy for winter or rainy seasons.

Installation and setup: what to expect

Installation is designed to be straightforward, especially compared to wired electric controllers. You’ll mount the unit near the valves, connect valve leads to the controller terminals, and insert batteries. Because the controller is battery-operated, you avoid mains wiring and can mount the box where it’s most convenient.

You’ll also download Hunter’s phone app (follow the manual for the exact app name or scanning code), pair over Bluetooth, and configure programs using an intuitive interface. The manual push-button gives you a fallback if you need to run zones while getting familiar with the app.

Practical tips for installation:

• Mount the controller on a flat surface at valve-box height or on a wall near the valve manifold.
• Keep it accessible for battery changes and inspection.
• Avoid placing it where sprinkler spray will constantly hit the face of the enclosure for extended durability.
• If using a soil moisture sensor or DC solenoids, verify compatibility before purchase.

Performance and real-world use

In real-world residential and light commercial settings, this controller performs well for the intended purpose: localized, battery-powered control. The Bluetooth connection is reliable within the advertised range, and the app provides a clear set of controls for programs, manual runs, and seasonal changes.

Battery life is usually adequate for typical household programs, but you should monitor the battery LED and change batteries proactively—don’t wait for a failure in the middle of summer. The waterproof enclosure means occasional direct moisture won’t immediately degrade performance, which you’ll appreciate in rainy seasons or in greenhouses with high humidity.

If you’re managing multiple NODE units across a property or several properties, the ability to control all of them from one app is a strong convenience factor. Just remember you’ll need to be within range of each controller to make changes unless you physically move between sites.

Where this controller fits best

This unit is great when you:

• Don’t have easy access to AC power near the valve box.
• Need a low-cost, no-subscription wireless control option.
• Want a straightforward install for small-to-medium irrigation systems.
• Use it in gardens, small lawns, parks, greenhouses, or remote irrigation off a single battery box.

It’s less ideal if you:

• Need remote access over the internet while you’re away from the property.
• Require integration with complex smart home ecosystems that rely on cloud services or voice assistants.
• Have extremely high-frequency irrigation cycles and prefer the reliability of AC-powered controllers for heavy use.

Troubleshooting common issues

You’ll likely encounter only a few common issues. Here’s how to troubleshoot them.

Bluetooth pair/connect problems:

• Make sure you’re within range and in line-of-sight if possible.
• Close and reopen the app, toggle Bluetooth on your phone, or restart the phone if needed.
• Verify no other app is monopolizing Bluetooth.
• Ensure batteries are fresh—low battery can reduce functionality.

Valves not activating:

• Confirm valve leads are connected correctly to the controller terminals.
• Verify you’re using a compatible DC solenoid (remember the controller doesn’t include DC solenoids).
• Check batteries; low voltage can prevent valve energizing.
• Manually activate the valve at the station to identify if the issue is the valve or the controller.

Water ingress or humidity concerns:

• Check the sealing gasket and mounting position.
• Ensure the unit is securely closed and the lid screws fully engage.
• If exposed to constant irrigation spray, consider a small, simple shelter or mounting under eaves.

Programming oddities:

• Re-check start times and run durations for overlapping programs.
• Use global seasonal adjustment rather than editing each station when you want a system-wide change.
• Suspend irrigation during rainy periods to avoid unintended watering.

Maintenance checklist

A simple seasonal and periodic checklist keeps your system reliable:

• Inspect enclosure and seals for cracks or damage once or twice a year.
• Replace batteries annually or when the battery LED indicates low life.
• Test valves manually using the push-button or app before peak watering season.
• Check sensor wiring and functionality if you use a soil moisture sensor.
• Update the app on your phone to get the latest features and bug fixes.

Tips to get the most from the NODE-BT-100-LS

• Group zones intelligently: Put similar plant types or similar sun exposure zones on the same program to simplify scheduling.
• Use Cycle and Soak for long run times: On clay or compacted soils and slopes, breaking long runs into cycles reduces runoff and improves uptake.
