Featured Product
A self-contained, industrial-grade control system for rural and off-grid water supplies — borehole, spring and pressure pumps managed from a single dashboard, with no cloud dependency.
Rural properties and remote sites often rely on a mix of boreholes, springs and pressure pumps to stay supplied. Manual oversight is impractical, and cloud-tethered controllers introduce a new single point of failure.
Our system runs on industrial hardware with a built-in web interface accessible over your local network — no account to create, no subscription to renew, no remote service that can disappear. Fault alerts are delivered instantly to your phone via lightweight push notifications.
Every installation is bespoke. We design the control logic, wiring and interface to match your site's pumps, tanks, pressure thresholds and flow targets.
Every feature designed for unattended operation on remote sites
Coordinated control of borehole pump, spring-fed gravity valve and freshwater pressure pump — each with its own logic, interlocks and safety limits.
Configurable periodic pumping with low-level lockout, startup grace period and maximum-runtime fault protection against runaway draw.
Spring intake split across daily slots with configurable target volumes. Automatic pause and resume based on tank level, surviving mid-slot power cuts.
Pressure pump is interlocked with confirmed UV lamp operation. No unsterilised water reaches the property. Hour meter flags scheduled lamp replacement.
Three independent pulse-counting flow meters with running totals, resettable trip counters and a live supply-vs-consumption balance.
Faults latch and require explicit reset — no silent recovery that hides a developing problem. Pressure, flow, runtime, level and UV failures are all independently monitored.
Fault alerts delivered to mobile phones via ntfy.sh. No account, no server, no app-store gatekeeping. Anyone responsible can subscribe in seconds.
Firmware upgrades are delivered over HTTP with automatic backup and restore of all counters and settings. No site visit required for revisions.
A complete web interface served directly from the controller: live status, event log, I/O diagnostics, simulation mode and a live wiring diagram. Nothing leaves your network.
Built on proven industrial components, not hobbyist kit
| Controller | Industrial PLC — dual-core ARM Cortex-M7/M4 at 480 MHz, wired Ethernet, built-in 24 V I/O |
|---|---|
| I/O Capacity | 24 inputs & 12 outputs via OPTA plus D1608S expansion module over I²C |
| Sensors | Pressure switches, float switches, pulse-counting flow sensors (10 L/pulse), UV lamp feedback, level probes |
| Communication | Wired Ethernet with static IP, local HTTP web server, JSON API, NTP time sync |
| Persistence | Versioned on-chip flash storage for counters, settings, logs and equipment state — survives power cycles and firmware updates |
| Alerting | ntfy.sh push notifications on fault conditions — zero-infrastructure, any number of subscribers |
| Deployment | DIN-rail mount for control cabinet installation, designed for 24 V field wiring |
Every site is different — pumps, tanks, pressure set-points, flow targets and fault tolerances all vary. Get in touch with a brief description of your setup and we'll discuss what a tailored system would look like for you.
