RTUs & Gateways
The box between the site and everything else. It polls instruments, buffers locally, and forwards when the link returns.

What we measure
10 parameters on this area.
Every reading is timestamped on arrival. Where the link drops, the gateway holds the readings and forwards them when it returns.
| Parameter | Symbol | Unit | Typical interval |
|---|---|---|---|
| Energy meters | AC / DC | pulse, Modbus | 1 min |
| Dimmer and LDR | — | %, lux | 1 min |
| Fuel sensors | L | % | 5 min |
| Solar, battery bank, UPS | U, I, SoC | V, A, % | 1 min |
| Fire and smoke detectors | — | state | on change |
| Flood detection | — | state | on change |
| Gas and water leak detection | — | state | on change |
| GPS and asset tracking | — | lat, lon | 1 min |
| Geofencing | — | in / out | on change |
| On/off device control | — | command | on demand |
What is fitted is decided at survey. This is the range we specify from, not a list of what every site gets.
Also monitored
The other four areas.
Environment
Air, water and effluent, recorded continuously rather than when someone remembers to take a reading.
11 parameters
Energy
Generators, street lighting, distribution assets and metering points, reporting state and consumption from wherever they are installed.
10 parameters
Agriculture
Water, power and climate on land nobody is standing on — tank levels, pump state, gate and store status.
9 parameters
Water Management
Wells, mains and reservoirs reporting between visits, so consumption is a continuous record rather than a monthly reading.
9 parameters
