    Hey friends, welcome back to The Sprinkler Nerd Show. Today, I want to take you down a slightly different path. This one's not about technology. Not about sensors. Not even about irrigation. It's about something more fundamental… something that shapes how we lead, how we teach, and how we grow. It's about the power of not knowing. Have you ever noticed what happens when someone asks you a question? What do you do? You probably give them an answer. That's what we've been trained to do. We associate knowledge with value. We think: if I have the answer, I'm helpful. I'm smart. I'm a good leader. But I want to challenge that today. What if giving the answer actually ends the conversation too soon? See, when we hand someone an answer, we're closing a door. We're wrapping it up. Putting a bow on it. Done. Solved. Move on. But growth doesn't happen in the answers. Growth happens in the thinking. In the wondering. In the exploration of possibilities. So what if, instead of handing out answers like candy, we responded with questions? Imagine this: Someone asks you, "What should I do about this issue in the field?" And instead of launching into your best advice, you say: "What options have you considered?" "What's the outcome you're aiming for?" "What do you think will happen if you try that?" Now, suddenly, you're not just giving a solution—you're creating space for discovery. You're not the answer key. You're the guide. That's leadership. That's coaching. That's power. Because when you help someone think—not just tell them what to think—you unlock something in them. You give them a skill they can use forever, not just an answer they'll forget tomorrow. And here's the twist: Not knowing isn't weakness. It's wisdom. It's humility. It's the birthplace of insight. So next time someone comes to you looking for an answer, try holding back. Ask a question instead. Keep the door open. Let the conversation breathe. Because the power of not knowing... might just be the greatest tool you have. Thanks for listening, and I'll catch you next time.

    #183 - For Immediate Release, Patent US3808385
    Apr 11 2025

    For immediate release—breaking news, kind of.


    In this solo episode of The Sprinkler Nerd Show, Andy dives into what seems like a revolutionary product: a mechanical rain sensor that requires no batteries, no Wi-Fi, no firmware updates—just pure, functional design. It shuts off irrigation during rainfall and turns it back on when conditions dry out, all thanks to hygroscopic discs that expand and contract to trigger a simple switch.

    This device sounds like the newest drop in water-saving technology—until Andy reveals the twist: it's not new at all. In fact, it's based on US Patent 3,808,385, filed in 1972 and granted in 1974. That's over 50 years ago. And the core concept of the mechanical rain sensor hasn't changed since.

    Andy breaks down how the device works, why it's still effective today, and what it says about the pace of innovation in the irrigation industry. He challenges contractors and tech developers alike to ask the big question: why are we still using 1970s technology in 2025?

    Could we create a smarter, data-driven rain sensor that actually logs rainfall events, provides historical context, and informs better irrigation decisions? If so—why hasn't anyone built it yet?

    Key Highlights:

    • Breakdown of how the moisture-responsive switch actuator works

    • Benefits for contractors: simplicity, reliability, zero maintenance

    • Installation and adjustment tips

    • Why the current state of rain sensors is a wake-up call

    • A challenge to the industry: let's rethink how we track rain and respond to it

    Andy closes the episode with a call to action for all Sprinkler Nerds: always ask why. Why things work the way they do, why they've stayed the same—and how we can make them better.

  • #182 - Approachable 2-Wire with Rain Bird's Steve Barendt

    #182 - Approachable 2-Wire with Rain Bird's Steve Barendt
    Apr 4 2025
    YouTube Short: https://youtube.com/shorts/flpTuNN7vqY Summary In this episode of the Sprinkler Nerd Show, host Andy Humphrey sits down with Steve Barendt from Rain Bird to explore the company's new ESP 2-Wire Controller—a product that's making 2-wire irrigation systems significantly more approachable for contractors who may have previously avoided them due to complexity. The Origin of the Conversation Andy first encountered Steve at the IA Show, where Steve delivered an impromptu 2-minute elevator pitch on the new controller. That pitch sparked Andy's interest in Rain Bird's new approach to two-wire systems, leading to this deeper dive discussion. Steve's Background Steve brings a decade of experience at Rain Bird, including seven years on the sales team working directly with contractors in the Austin, Texas area. His background in the field informs his work as a product manager, enabling him to better understand real-world customer needs and challenges. Why "Approachable" Matters Historically, two-wire systems have been considered complex, especially around wiring specifications, connector types, and troubleshooting. Rain Bird's ESP Two-Wire Controller aims to lower the barrier to entry, making it easier for contractors—even those new to two-wire installations—to adopt the technology. The term "approachable two-wire" is intentional. Steve explains that Rain Bird designed this controller to work with standard irrigation wire and connectors, rather than requiring specialized components. As long as the wire is direct burial irrigation wire (down to 18 gauge) and connectors are rated for 600 volts, users can leverage what's already on their trucks—reducing the learning curve and installation costs. A Big Shift: De-Energized Two-Wire Path A key innovation is that the two-wire path is not constantly energized, as it is in traditional two-wire systems. Instead, it's only powered when actively running a station or performing diagnostics. This reduces heat at the connectors and decreases corrosion risks, allowing the use of standard connectors and simplifying troubleshooting. Positioning: Who's It For? The ESP Two-Wire Controller isn't designed to replace all two-wire systems. Instead, it's aimed at light commercial and large residential projects with about 12 to 30 stations—an area where contractors often debate between traditional wiring and larger two-wire systems. Key highlights: 50-station capacity (though ideal use is around 12–30 stations) Cost break-even point starts around 12 stations, lower than the 30+ typical for traditional two-wire setups Two solenoids can operate simultaneously Compatible with a standard flow sensor (hardwired) By offering a lower break-even point and simpler installation, this controller fills a gap between traditional modular controllers like the ESP ME3 and higher-end commercial platforms like LX IVM. Troubleshooting Tools and Diagnostics Rain Bird has invested heavily in diagnostics features that make this controller easier to troubleshoot: LED Feedback on Decoders: Each decoder includes red, green, and blue LEDs that indicate operational status, short circuits, and open circuits. Short Finding Mode: Allows energizing the path for diagnostics with a clamp meter. Power-Measure Mode: Helps track power issues in the field. These features empower contractors to isolate and resolve issues faster without needing advanced tools or specialized knowledge. Auto-Addressing Decoders Perhaps the most contractor-friendly feature is the auto-address functionality. Rain Bird decoders come in numbered order, and if installed sequentially, the controller will auto-scan and assign decoder addresses to stations with no manual input. This drastically reduces setup time and minimizes human error. While other systems may require manual address entry or use specialized software, Rain Bird's solution is faster and simpler—especially when paired with the mobile app. No Field Grounding Required Another simplification: unlike other two-wire systems, no field grounding is required for this controller. Though contractors can choose to ground the system if they wish, it's not necessary for functionality or warranty compliance. Connectivity and Software Integration The controller is WiFi-enabled via Rain Bird's LNK2 module. It currently connects to Rain Bird's legacy mobile app, but a transition to Rain Bird's 2.0 app and IQ 4 web platform is planned for 2025, which will bring expanded access and remote management options. Simplified SKUs and Installation Rain Bird is offering this platform with just two SKUs: the controller and a single-station decoder. That's a major advantage for distributors and contractors, who won't need to manage complex inventories of sensor decoders, grounding kits, or multi-station decoders. Behind the Scenes: Product Development Steve shared insights into the 2–3 year development timeline, which included field testing, focus groups, and ...

    #178 - Bespoke or A.I.
    Feb 1 2025

    In this episode of The Sprinkler Nerd Show, host Andy Humphrey starts off with an unapologetically bold greeting to illustrate the power of authenticity and grab listeners' attention. He gives a personal shout-out to friends, mentors, and colleagues he connected with during the week—highlighting the importance of real human relationships in an increasingly AI-dominated world.

    From there, Andy explores the rapid growth of AI and how it's poised to deliver personalized, mass-produced podcast content—comparing it to Walmart's ability to provide inexpensive, standardized groceries. But just as many people still prefer organic, home-cooked meals, Andy argues that listeners will continue to value authentic, human-created content. He emphasizes that AI, while a remarkable tool, simply can't capture the spontaneous quirks and genuine emotion inherent in a show crafted by a real person.

    Ultimately, Andy encourages creators (and listeners) to lean into their unique perspectives and passions. By embracing technology where it's helpful but maintaining the "handcrafted" essence of podcasting, we can build deeper connections and a vibrant community that values the human touch—something no AI can replicate.
