The clock is ticking. In 6 days, Cassie and Bobby from Sparx will be showcasing their patent-pending smart fire sprinkler technology at the NFPA Conference and Expo, and the energy in the room (and on the Linear board) has been electric.

I just pulled everything they moved to Done from the past three months. 46 tickets completed. Here’s the story of what they shipped.

The Mission: Show the World What’s Possible

The NFPA Conference and Expo isn’t just another trade show. It’s the gathering for fire protection professionals, engineers, and safety innovators. For Sparx, this is a chance to demonstrate live what their wireless smart sprinkler system can do: from sensor-based early detection to coordinated electronic activation.

The goal? A fully functional demo that stops traffic (and maybe saves a few hypothetical buildings in the process).

What They Shipped

The Hardware Sprint

The physical devices are where it all starts. Cassie and Bobby spent significant time getting the hardware battle-ready:

• Reducing power consumption on Edge Devices for improved battery efficiency
• Building electronically activated sprinklers using JOB GmbH’s R-Type Thermo Bulb technology
• Testing new antennas for reliable wireless communication
• Assembling electronics enclosures with switches, lightpipes, mounting pads with mounting straps, and battery clips
• Soldering components and building a 4th board to support additional sensors (the stretch goal they actually hit)
• Testing smoke/temperature auxiliary boards with custom test firmware and hardware validation

The Hub Gets a Major Upgrade

The Sparx Hub — the touchscreen brain of the operation — received its biggest polish pass yet:

• Smoke sensing is now visual on the Hub. Real-time smoke detection, displayed beautifully
• Temperature sensing upgraded for digital sensors. Goodbye analog, hello precision
• Device discovery redesigned. Clearer Device IDs and better search
• Navigation and page state fixes, because a smooth UI demo is half the battle
• Color scheme consistency between the Map and Sensor Data pages
• Device selection and zoom behavior finally behaving like users expect
• Offline devices correctly flagged as “trouble” instead of “supervisory”

The BIM Bridge

One of the biggest leaps since last year’s NFPA isn’t something that’ll be demoed front-and-center at the booth, but it’s what makes the Hub’s visual intelligence possible.

Cassie and Bobby built a Revit plugin that lets the design team assign Device IDs directly to sprinklers in their BIM models. Those IDs become a starting point for where devices get installed in the field, with installers able to fine-tune positions right on the Hub when needed. The plugin exports a .sparx file (Sparx Project File) that feeds into the Sparx Installation Tool, a simple but critical app that wirelessly uploads that project file to the Hub.

The result? The Hub doesn’t just see a list of sensors. It understands the building spatially — overlaying live sensor readings onto the actual floor plan and building model. They also added support for custom labels on those plans: fire department connections, sprinkler rooms, riser locations, and whatever else a facility needs marked.

It’s the bridge from CAD to reality, and it’s why the Hub demo at NFPA shows more than data. It shows context.

The Logistics of Getting There

Hardware and software are only half the battle. Getting to NFPA requires its own project management:

• Ordered Sparx stickers and branded notebooks from 4imprint
• Purchased a Home Depot table and chairs for the booth
• Arranged shipping for floor tiles, marketing materials, tablecloths, and the Sparx banner
• Created a new marketing poster and took photos of the latest device builds
• Planned the booth setup down to the last giveaway item

The Numbers

• 46 issues completed in the past 3 months
• 15 issues tagged to the “NFPA June 22nd Prep” project
• 5 issues for the Installation Tool + Revit integration
• 26 UI/UX improvements on the Hub — many in the past week alone
• 2 major refactors: migrating the service workspace to TypeScript and remodeling devices as containers of sensors

What’s Left

With the expo just days away, the team is in the final stretch. The devices are built, the Hub is polished, the poster is printed, and the booth gear is en route. Now it’s about comprehensive end-to-end testing — making sure every sensor reports correctly, every sprinkler responds on cue, and every edge case has been handled.

Because when you’re demoing fire safety technology at the NFPA Conference and Expo — with 8,600 attendees from 88 countries — “works on my machine” isn’t quite good enough.

Good luck at NFPA Conference and Expo, Cassie and Bobby — Sparx is going to turn heads. 🔥
