DWP Sprinklers
Wireless sprinkler valves you screw on, and then forget about. Most home sprinkler systems are wired through the yard; when a wire breaks, the zone dies. This replaces the wire: unscrew the old solenoid, screw on a battery-powered one, and a hub on the wall opens it over LoRa radio.
How it works
Three parts, one job: water the yard and leave you alone
- 1
Sprinkler Transmitter
A LoRa hub on Wi-Fi that opens each zone's valve over radio. Designed to keep the day's schedule itself, so the yard keeps working if the internet doesn't.
- 2
Smart Solenoid
A battery-powered driver for a latching solenoid, sealed in the valve box with no wires to the house. Rev B, now specced, moves to 4×AA with a boost + supercapacitor stage.
- 3
App + cloud
Version one does one thing: water now. Weather-adjusted scheduling, computed in the cloud and handed to the hub, is the next step.
The approach
Validate the production design before ordering a single board
No throwaway prototypes
The first boards ordered will be the design that scales. Layouts pass design-rule checks, the netlist is matched pin for pin, and the firmware's safety logic is mutation-tested before anything is fabricated.
Built for someone else to assemble
Plug-in solenoid leads, Tag-Connect flashing, no hand soldering. A contract manufacturer can't get it wrong, and the homeowner never sees a board.
Supply chain checked at scale
Parts are picked against 1,000-system volumes, with second-source footprints where stock is thin.
Where it is
- NOW
Rev A boards verified; rev B specced
- NEXT
One EU test unit: press a button, open a valve 100 m away
- THEN
US boards, first installs in Texas
- LATER
DIY kits, sealed production cases
